A CNC Machine device is used in carpentry suppliers and some other commercial configurations. They are very costly, so most people do not buy them, although used ones can be acquired more effortlessly. They are essential for rate and reliability in huge, recurring projects. There are many uses in market for CNC models. Routers routine gaps, for example. Many CNC models are capable of doing a variety of projects at once, increasing performance in the developing procedure. The technological innovation behind these models is Pc system Numerated Management. This technological innovation was designed in the nineteen seventies and it allows for a device to be designed in progress so the functions are set up to function almost instantly. The preliminary installation is a little challenging, but once that is done it is easy to work. A CNC wireless router would be designed to routine an opening regularly at certain durations. This is much more powerful than guide computation and exploration and reduces inconsistency due to people problem or exhaustion. A CNC lathe would be used to cut items of wooden of consistent style. Lathes can have energy including 15 to 40 HP, and how much energy is required will depend on the job being done. A good CNC lathe will allow you to function at various amounts of computerized, so that you can function all guide, or all computerized, or any collaboration in between.

Delivering Long-Term Value For CNC Machining Operations

CNC Machines January 20th, 2012 by cnc machines, cnc routers, types of cnc machines, used cnc machines, cnc machines for sale, cnc milling machines, hobby cnc machines, cnc machines manufacturers admin

By educating customers on coolant best practices, Quaker helps customers manage their costs for the long term

Conshohocken, PA /PRNewswire/ - Computer Numeric Control (CNC) machining is when the functions and motions of a machine are controlled by an automated program. CNC is beneficial in machining and grinding operations because of its high accuracy, short production time, and greater flexibility. It can be used for multiple types of metals, but requires a metalworking fluid that provides a high degree of lubricity.

When Bahrat Electronics Limited (BEL) — a state-owned electronics company manufacturing advanced electronic products for the Indian Armed Forces — was experiencing problems with their metalworking fluid performance, tool life, hazardous waste generation and coolant odor in their CNC machining center, they turned to Quaker Chemical experts for help.

After analyzing the situation which involved the machining of brass parts, Quaker recommended switching to QUAKERCOOL® 3890 — a metalworking fluid designed for non-ferrous, medium-to-heavy duty machining and grinding operations requiring a high degree of lubricity, cleanliness, cooling, and corrosion protection — for all CNC machining operations. The change to QUAKERCOOL® 3890 offered improvements from day one, including increased tool life, reduction in hazardous waste generation and elimination of bad odors. BEL continues to experience these positive results 24 months later, with no change out of product — providing additional cost savings in process fluid purchases.

“Since the changeover to QUAKERCOOL® 3890,” said Kubera Naik B V., Manager/ CFF at Bharat Electronics Bangalore site, “we have experienced elimination of bad odors, which had been a major problem, and increased sump life while maintaining tool life, finish, and operator friendliness.”

As additional support, Quaker’s technical experts provided on-site training related to metalworking fluids, to share best practices in coolant management and help the customer better understand the subject matter.

“We are very happy with the day-to-day service, the prompt technical support, and efforts being extended to ensure total customer satisfaction from Quaker,” comments Mr. Naik.

IBAG high speed electrospindles add capability to Star CNC sliding-head lathes

CNC Machines January 17th, 2012 by cnc machines, cnc routers, types of cnc machines, used cnc machines, cnc machines for sale, cnc milling machines, hobby cnc machines, cnc machines manufacturers admin

CNC sliding-head lathes fitted with one or more high speed spindles, capable of milling and drilling at up to 100,000 rpm, can extend the range of applications that are possible, and Star Micronics GB has demonstrated as much.

  • Star CNC sliding-head lathes

Star collaborated with electrospindle specialist Emmaco to install a lathe fitted with an 80,000 rpm IBAG spindle at a subcontractor in the North of England. The company needed to drill a 0.5 mm cross hole in a brass component, but the lathe’s 8,000 rpm driven tool speed was insufficient to achieve the ideal surface speed for efficient machining.

By fitting an electrospindle capable of 10 times the rpm, cutting speed was increased to around 40,000 rpm (63 m/min), resulting in better surface finish, higher productivity and reduced tool wear.

Ian Baker, managing director of Emmaco UK cites another application, this time in the medical sector. The cycle time for machining bone screws on a CNC sliding-head lathe was reduced from 7 minutes to 45 seconds by retrofitting an IBAG spindle. A further advantage was the elimination of burrs that were previously created by milling at sub-optimal speeds.

Mr Baker says that there is considerable interest at the moment from medical companies in high-speed units, especially for milling stainless steel using typically 2 mm diameter cutters. Not only are the best machining parameters attainable, but also the IBAG drive is particularly smooth, resulting in very fine component surfaces approaching a mirror finish in some instances. One US manufacturer has installed no less than 17 such spindles on one Star lathe.

There are over 60 high-speed spindles in the IBAG range suitable for fitting to CNC sliding-head lathes, including some designed specifically for mounting on the rear toolpost on Star machines. Fixed-angle and adjustable-angle units extend the machining possibilities.

Debt management guided tiny machine shop to success

CNC Machines January 16th, 2012 by cnc machines, cnc routers, types of cnc machines, used cnc machines, cnc machines for sale, cnc milling machines, hobby cnc machines, cnc machines manufacturers admin

The economic downturn that crippled so many industries in Southwestern Ontario just may have been a turning point in the growth of Attica Manufacturing Inc.

The Dundas St. East business, owned by Andy Mavrokefalos, is a machine shop just west of Highbury Ave. that creates new parts and products for area industries, exactly the kind of business that gets hammered in a recession when industries aren’t buying.

Though sales plummeted at Attica in 2009 and 2010, owner Mavrokefalos used that time to invest in new equipment and technology, spending cash and taking on debt.

“We put more money in during the recession than we ever did in the history of the company. We did take on debt to do it; debt management was very important to us,” he said. “If we didn’t buy the machines, I don’t know where we would be right now. It increased our depth with existing customers, and widened (products they could offer) those companies.”

The investment enabled Attica to outbid, by as much as 50%, competitors going after the same business, including some Asian bidders, Mavrokefalos said.

That is the power of investing in a down economy, so a business can be better positioned for recovery when the economy shows signs of stability and growth. Now Attica is enjoying its best sales growth, year over year, in its nine-year history.

“We have taken our punishment and now this year looks very healthy. (The year) 2011 was a good year for us,” Mavrokefalos said.

Sales are up about 25% in the last two years, he said.

If Mavrokefalos had to pinpoint a reason, for Attica doing well in tough times, he looks no further than across the shop floor in his machine shop.

There, his father, Gerry (Gerassimo), 73, still comes to work every day, where he runs his own business C&M Machine that shares the business space with Attica.

“He can outrun a lot of 20-year-olds for sure,” Mavrokefalos says, laughing.

“My father didn’t give me a platform, it was more like a springboard. Today, he advises me still. He has been through so much, so many downturns, recessions, there is nothing like having a mentor beside me always to guide me through rough patches.”

C&M was where Mavrokefalos got his start at 14, cleaning toilets and machines and sweeping floors. He worked his way up until he branched out with his own business, Attica, in 2002. But to this day the two businesses are in the same building.

Mavrokefalos also is quick to praise his mother Athena. She worked for years as a hairdresser before having children. After staying home with them, she began working in administration at the plant.

Working at his father’s business steadily since he was 14, Mavrokefalos graduated from Westminster secondary school at 17 and enrolled at Fanshawe College.

He studied machining. After graduating in 1991, he returned to his father’s business.

“The shop was small. We only had about six people, but we had a lot of work - Kellogg, Ault Dairies, Labatt and we did work for Cami,” Mavrokefalos said.

In 1997, C&M bought its first CNC machine. In the world of machine shops, the machine is the Cadillac of technology because it lathes and machines parts faster and for less money. But the machines themselves are expensive.

“My dad knew I was itching to try (CNC machines), but it really helped the rest of the shop, too. We were able to produce a lot more than on conventional equipment,” Mavrokefalos said.

It was soon after that investment he got a call from another machine shop, looking for a shop with CNC techhnology that could help it fill orders. Mavrokefalos took on the work. They began making thousands of parts, a tall order for a small shop.

“All of a sudden I got this bug, this burn, trying to find more work, more production and machining . . . Within a year we had a second CNC machine, going from dozens of parts to thousands, from using equipment worth $18,000 to $90,000 and another year later, $140,000.”

It was soon after that Mavrokefalos struck out on his own, under the wings of his father, forming Attica. C&M provided parts for equipment and machinery, to keep its operation running, whereas Attica makes parts to sell to other industries, a supplier.

Today, C&M is Attica’s biggest supplier, meaning father and son still work closely, and that suits Mavrokefalos just fine.

“My father was not like a lot of Greek dads. He was very patient. Every time I made a mistake the first question he asked is ‘What did you learn.’ It’s incredible what that does to a kid’s confidence, to take a risk and not be afraid to get your hand slapped.”

Mavrokefalos’ strategy to expanding is the “snowshoe effect,” creating as wide a footprint as possible to diversify his business.

The biggest challenge this year could be finding a new home. Attica is at full capacity in its 24,000-square-foot shop and is looking for a 50,000-square-foot plant, he said.

Attica is nominated this year in the quality category in the London Business Achievement Awards. The business was also nominated in 2009, being named a finalist.

“It is an honour,” said Mavrokefalos of the nomination.

Mavrokefalos’ voice rises with pride about visiting Kefalonia in the northwest of Greece, the island his parents hail from. His aunts showed him drawings his father did as a young man in Greece attending technical school.

“He never told me how well he did, not a word. He won all these awards. He entered in national technical drawing competitions. I didn’t know any of this. I was amazed. He is so humble.”

Mavrokefalos’ father never pushed into the field, saying only he needed help in the shop, but Mavrokefalos grew to love the work.

“My dad wanted to give me my wings and I felt ready,” he said of opening his own company. “He runs a tight shop and it has seen him through very challenging times. I have to rely on his experience.

“I can make all the decisions about Attica, but I don’t. I look to my dad and he has to be on board. He does not have one share (in Attica) but I have tremendous respect for my father. I am his son, first.”

Dovetail Machine and Wood Clamps Assessment of Machine Hazards

CNC Machines January 16th, 2012 by cnc machines, cnc routers, types of cnc machines, used cnc machines, cnc machines for sale, cnc milling machines, hobby cnc machines, cnc machines manufacturers admin

It is very important to assess machine hazards for machinery like bin tipper , dovetail machine, edge banding machine, etc. to prevent human injury & death. No matter, which industry you are in, it is very essential to maintain industrial equipment and tools like wood cutting tools , wood clamps, dovetail machine, magnetic drill , edge banding machine, edge cutter, mortise chisel , chisel mortiser, wood CNC router, etc. in good condition. This will extend the life of the machinery and will not affect productivity or cause disruption in routine activities.

It is very important to carry maintenance procedure for industrial equipment and tools like mortise chisel, chisel mortiser , wood CNC router, turret lathe etc. Maintenance process will keep the machinery working in good condition all the times and will increase its efficiency. Besides maintenance, it is very important to install machine safety guards to prevent human injury or death. Machine related hazards may appear during machinery installation, operation or maintenance.

Safety guards are designed to get rid of potential hazards of machinery. You should adopt hazard control methods, which can reduce the hazard levels to a great extent. Selection of hazard control methods should be done on the basis of hazard control hierarchy. Manufacturer of machines usually design these guards.

All important details like installation process, operation and maintenance are specified in the manufacturer’s manual. However, there may be certain hazards which may take place after the machinery is installed at plant site. Possibility is there that such hazards have not being included in the safety manual. Such problems are very common and are result of various factors like extreme process condition or interaction with nearest moving equipment.

Identify the machinery

The first thing you should do is identify machinery like dovetail machine, edge banding machine edge cutter , etc. operated in your industry. Industrial equipment can be identified based on their types, area of their placement & source of energy used for operating machines. This will let you identify machines, which will be helpful in assessment of machinery hazards, before you determine safety guards. Assessment of machinery hazards for safety

Even though, you have a safety manual with you still it is very important to assess machine hazards of various industrial tools like wood cutting tools , wood clamps, etc. and risk assessment to ensure that no hazards are left out to be assessed.

To read more about importance and details of maintenance process for wood cutting tools, wood clamps, dovetail machine, edge banding machine, edge cutter, mortise chisel, chisel mortiser and wood CNC router , you can refer to related sites on Internet.

CNC Machines January 13th, 2012 by cnc machines, cnc routers, types of cnc machines, used cnc machines, cnc machines for sale, cnc milling machines, hobby cnc machines, cnc machines manufacturers admin

Rentapen’s CNC Operator, John Dinon and CAD Drafter Kory Maier, attended a two day training course in New Berlin on the new 3D software, FeatureCAM. CAM (computer-aided manufacturing) is computer software that can be used for CNC machines.

“FeatureCAM will benefit Rentapen, because it will allow us to create more custom products for our customers,” said Kory Maier. CAM software greatly reduced the time required to program the CNC machine to produce a custom product.

FeatureCAM software will help Rentapen create custom products quicker which will make the weld fixtures that Rentapen builds for its customers be even more economical.

Rentapen has already greatly reduced the costs of weld fixtures for manufacturers through its line of standard yet versatile blocks, plates, clamp risers and shims. These RAPid Tooling Components™ are a part of Rentapen’s mission, which is to save manufacturers costs in their weld fixtures.

Kory Maier is a CAD drafter using Pro/E Wildfire 4.0 software for modeling and detailing parts and assemblies as part of Rentapen’s customers. “We thought Kory would be a good person to learn the software,” said Susan Straley, Queen of Lean Machine Design, President at Rentapen Inc.

Maier joined Rentapen as an intern from WCTC the area’s technical college and was quick to learn. He started full time on January 9th as a CAD Drafter for Rentapen.

“His excitement and enthusiasm for learning and using the CAM software fits right into the culture of learning here at Rentapen,” said Straley.

“FeatureCAM, a feature-based CAM system, incorporates support for 64-bit computers, improved data exchange from a wider range of design software, the ability to use stock models and new strategies across the complete program, from turning to five-axis machining.” (News. Delcam Issue 3 2010)

VTC Revitalized with New CNC, AC Servos

CNC Machines January 12th, 2012 by cnc machines, cnc routers, types of cnc machines, used cnc machines, cnc machines for sale, cnc milling machines, hobby cnc machines, cnc machines manufacturers admin

Most U.S. shops take for granted the quality and reliability of their electric power, though invariably there are power fluctuations and outages, and in some regions of the world these are inescapable. Operating CNC machine tools in such an area will underscore how well a machine control can handle a power ‘hiccup’: Can the CNC recover quickly or does it forget what planet it’s on?

A significant percentage of Helac’s parts pass across the shop’s MAG VTC: a 36-inch, fixed-height, 2-axis machine that was sensitive to power outages.
Retrofitting an older MAG VTC with a new Fanuc 0iTD CNC, AC spindle, servo drives, and motors ended recurring problems caused by regional power outages. Commonality with other Fanuc controls in the shop improved programming efficiencies and training.
Helac’s MAG VTC does heavy metal removal on the tube-shaped housings used for many actuator models, using a 3-pallet pool of queued work to stay in production during much of a +80-hour work week. Workpieces are DOM tubing and alloy steel, weighing 60 to 500 lb. The tubular parts have welded steel flanges on each end and some have off-center plates on the sides. These are mounted on an angle plate that has half-rounds to locate off the OD of the tube.
Helac actuators provide swing, steering, head rotation, articulation, and similar capabilities, with drift-free, brakeless positioning, and protection from overload conditions.

Jerry Gilara, director of Continuous Improvement, and his maintenance team at Helac Corporation in Enumclaw, WA, knew the answer for an older vertical turning center that is a vital operating unit for the plant, and a workhorse production unit. It is critical to Helac’s production program. Built in 1998, the MAG VTC experienced significant downtime with every power hiccup.

“This is a rock-solid, very capable machine, but it’s older CNC and DC drives/motors were an Achilles heel,” Gilara explained. “We’ve always been pleased with the machine, so we had MAG retrofit a new Fanuc CNC and AC digital axis drives/motors and spindle. The retrofit transformed the machine, making it utterly reliable and giving us other advantages because of the widespread use of Fanuc controls in our shop.”

Helac’s main products are helical hydraulic rotary actuators, a clever device that translates linear piston movement into rotary motion. Extremely compact, the Helac actuator produces high torque with high load-bearing capacity, making it an ideal positioner or steering component for mobile construction equipment, forklifts, aerial platforms, utility vehicles, agricultural equipment, marine applications, etc. The actuators provide swing, steering, head rotation, articulation and similar capabilities, with drift-free, brakeless positioning, and protection from overload conditions. The device is covered by many patents and has been adapted and sized for numerous applications.

Gilara said a significant portion of Helac’s parts pass across the MAG VTC, a 36-inch, fixed-height, 2-axis machine. The machine does heavy metal removal on the tube-shaped housings used for many actuator models, using a 3-pallet pool of queued work to stay in production during much of the plant’s +80-hour workweek. Several hundred different part numbers are involved, made of DOM tubing and alloy steel, weighing 60 to 500 lb.

The tubular parts have welded steel flanges on each end, and some have off-center plates on the sides. “We mount these on an angle plate that has half-rounds to locate off the OD of the tube,” Gilara continued. “We bore the part completely in one shot from the top, with tolerances of 0.001 in. Then, we face two parallel surfaces so everything is concentric. We do all the machining from one end, using a 250-lb boring bar with a CAT 60 taper, which is a primary reason we purchased this machine. We have a backup machine for this work, but that machine is what caused us to purchase the MAG unit. When our primary machine is down, we’re quite unhappy, because parts aren’t moving through production.”

Because power quality is often in question due to wind conditions in this area of Washington, the machine’s control frequently lost its memory during brief power outages. “Every time the power ‘hiccupped’ the control would lose memory, even with an outage of just a minute, and it could take a day or two to reload all the programs,” Gilara explained. “If it happened on the second shift when no maintenance people were available, the machine might sit idle until morning before someone could work on it. The CNC hardware and DC drives had become liabilities, too.”

Helac discussed a retrofit of the CNC and drives/motors with MAG in 2009, and the new hardware – a Fanuc 0iTD CNC, AC spindle, servo drives and motors – was installed in 2010. MAG offers pre-engineered, modular retrofit packages with pre-built panels, providing a modular approach that represents an economical retrofit of just the CNC, or the CNC with servos, spindle drive and motors – at different times, if needed, to distribute the cost as budgeting may require.

MAG is a machine tool builder and machining systems developer. It offers pre-engineered retrofit kits for many models of its legacy brand VTLs, HBMs, lathes, HMCs, VTCs and 5-axis machines, utilizing Fanuc, Fagor and Siemens control solutions.

“Our power-quality issues have become non-issues since the retrofit,” according to Gilara. “We went through an entire winter without a problem. And, the similarity of the Fanuc control to others in our shop has given us advantages in programming and training. We can now post process to a Fanuc file, like the rest of the machines in our plant, and operators familiar with other machines in our plant can migrate to this machine with less training. The faster data handling of the new control also yields improvements in finish. Given this machine’s workhorse capability, accuracy and repeatability, the retrofit has proved a cost-effective investment.”

CNC Machining General Information

CNC Machines January 12th, 2012 by cnc machines, cnc routers, types of cnc machines, used cnc machines, cnc machines for sale, cnc milling machines, hobby cnc machines, cnc machines manufacturers admin

CNC machining refers to any process that uses a CNC machine. This could be for routing, milling, drilling, or other types of work that is done with metal, wood or other materials. This is a manufacturing process that uses the automatic opportunity from the computer to create shapes or forms that must be precise.

Raw materials are used and they are put into a CNC machine that uses cutting tools to make these shapes. The CNC machining process involves computers that have at least one microprocessor and several units for storage. With CAD or CAM software systems added to CNC the computer can be programmed to produce the precise movements that are able to create the part.

In CNC machining the process is automated which saves the operator time and saves the business money. The operator is able to load the materials, program the machine and then the machine can work without attention when set up properly; the amount of time it is run without attention is also programmed in.

An important aspect of any CNC machining is for the operator to know the machine well. CNC is an addition to the general aspects of the machine. As an example, if you are doing routing, adding CNC to the process only automates it. However, for the operator, it means that they must understand the machine, how to put in codes or use CAD or CAM and how to operate the machine; they must also understand how basic routing works.

Another area that is important in order to understand CNC machining is the basic components of the machine. It is important to know how these machines operate in order to fix them if something goes wrong. This also allows the operator to understand the limitations and the capabilities of the machine to get the most out of its use.

As CNC machining becomes a project the operator is in charge defining five areas. They will first think about the project they want to design and plan it out. This is where sitting down and drawing out plans will be a good idea.

The next area is to understand CAD to translate the drawing into the computer and then an understanding of CAM to translate the CAD information into machine language. In the final area the individual must understand the Controlling function in order to make the machine do what is required. When all these areas are fulfilled properly they allow the individual to create the project in the way they saw it in their drawing.

CNC machining was traditionally only done in commercial settings with very large CNC machines. Today, there are mini-CNC machines that allow the process to be done on a smaller scale in a home workshop. This has allowed the smaller business to be able to take advantage of building a variety of parts and products that were not previously available except on a larger scale.

CNC machining can produce both simple and complex designs and can be used on a variety of materials including aluminum, foam, wood and other metals.

Coagh firm CNC Components goes bust with up to 50 jobs lost

UP TO 50 jobs have been lost after one of the Northern Ireland’s leading independent manufacturers based in Coagh went bust.

CNC Components which makes doors and accessories for kitchen and bedroom units called in the administrators on Monday.

However local firm Orrlee Kitchens which operates nearby has quashed all rumours that it is linked to CNC Components.

Managing director of Orrlee Robert Watson said while it is tragic that CNC had gone under, his firm, which manufactures kitchens, is thriving and still operating as a successful business and has no connection to CNC Components.

In a statement to the Mid Ulster Mail, the Director of CNC Components Tim Dillon, blamed the demise of his company on ‘major challenges in trading through a depressed market and consequential cash flow problems’.

Mr Dillon said: “It is with the greatest regret that we have reached this difficult decision which we believe is the only choice we have been left with. On behalf of myself and all the directors we would wish to pay tribute to the dedication and professionalism of our staff who have supported us throughout these difficulties.

“We would also wish to recognise the support of our customers and suppliers over the years.”

CNC Components (U.K) Limited was established in 1988 and employed more than 40 staff. The company operates from premises at Ruskey Road, Coagh.

John J. Cavanagh, of Cavanagh Kelly, the Administrator, has assessed the position of the company and the decision was taken to cease trading with immediate effect. The Administrator is considering options to sell the business and assets of the company. All opportunities to fulfil existing orders for customers are being explored.

Interested parties in the business and assets of the company should contact the Administrator’s Office at Cavanagh Kelly, 38 Northland Row, Dungannon, BT71 6AP telephone 028 8772 1194

Ulster Unionist Councillor Trevor Wilson, Chairman of Cookstown Enterprise Centre, said: “It is disappointing to hear of the loss of jobs at CNC components.

“It will be extremely difficult for those employees and their families who have been affected by this closure. The company has been a major employer in the area and the job losses will be a severe blow to the local economy.

However Councillor Wilson was keen to point out that nearby Orrlee Kitchens is still a thriving business.

“I would like to assure any customers and potential customers that Orrlee Kitchens are not part of CNC Components and are trading successfully,” he said.

Mid-Ulster DUP Assembly MLA Ian McCrea, has voiced his disappointment at the news that CNC Components based near Coagh has closed its doors, resulting in many jobs lost.

Councillor McCrea said: “It is with great sadness and disappointment that I heard of the closure of CNC Components a company that has served the community well over many years giving employment to many local people during this time.

“During these hard economic times and with growth slower than expected, it is understandable that businesses find it very difficult to stay afloat and I am in no doubt that the owners tried everything possible to keep the business running and that closure was a last resort.

“The knock on effect to the families of those employed at CNC components whose loved ones have lost their job is devastating and with rising living costs, times have never been tougher and I want to assure everyone that my constituency offices are open to help them to ensure they get everything they are entitled to.”

Ulster Unionist Sandra Overend also expressed her disappointment.

The Mid Ulster MLA said: “Unfortunately due to the current difficult economic climate some of our local businesses are finding it more and more difficult to sustain their future, and Mid-Ulster is witnessing a share of business closure as well as those going into administration.

“It a very difficult climate in which to thrive – the world is a much smaller place and competing companies are not just within Northern Ireland, the UK, or Europe, but across the globe.

“I am very saddened to hear of the closure of CNC Components - a local business which was trying to survive in a very competitive market. As a new year begins we do try to be optimistic for the future but it will be especially difficult for the forty people who are now without jobs, as well as the management.

“CNC Components is based at Ballynewy, Coagh; the land there was farmed by my late grandfather during the late 1940’s and I have often been proudly told of the family business that grew in Ballynewy after my grandparents moved to Stewartstown.

“I am saddened that CNC components has met its fate, however, I am glad that Orrlee Kitchens which is on the same site continues to thrive and I wish them future success.

“I offer my support to those affected and ask them to contact me if I can be of any assistance, at any time (Tel: 86748090 or 90520305) or call into my constituency office at 1 High Street, Moneymore.

“In times of austerity, which we currently find ourselves in, it is more important than ever that the government strives to work together to promote economic recovery and growth. The Ulster Unionist Party will continue to champion this need and drive the economy forward as best it might.”
