With a functional range from manual turning to full CNC, the Haas TL-1 Toolroom Lathe features a proprietary conversational operating system that makes cutting parts and creating part programs nearly effortless. The operator chooses an operation, touches off the X and Z surfaces, and is then prompted to enter basic dimension information. Default values for feed per revolution, spindle speed and depth of cut are automatically entered by the control, but may be changed by the operator.

Once all necessary information is entered, a push of the Cycle Start button performs the desired operation.

A Recorder function allows information to be saved for future retrieval.

The TL-1 operates in four modes.

In all modes, the Haas control provides extremely accurate digital read-out (DRO) of position, displayed to 0.0005in when using the manual handwheels or to 0.0001in when using the electronic jog handle.

Electronic soft stops may be set to limit the travel of the lathe.

In manual mode, the X and Z axes are moved via standard handwheels.

In semi-automatic mode, the TL-1 performs simultaneous linear interpolation for both axes using a single handwheel.

ID/OD chamfers and tapers, for example, are easily cut in semi-automatic mode.

In automatic mode, built-in machining cycles (both single- and multi-pass) are available for rough and finish profiling, chamfering, grooving, parting off, threading, drilling and tapping.

In full CNC, the TL-1 is programmed using standard G code, and all axis motion is regulated by the Haas control via a G-code program.

Operations that would be difficult or impossible on a manual machine, such as radii, tapers, profiles, grooving, ID and OD threading, and rigid tapping, are all possible on the TL-1 - without knowledge of G-code programming.

Help menus are available directly on-screen, and a dry-run graphics feature allows operators to check their work before running a part.

MACH 2006 witnessed several new machines from Haas Automation, the largest CNC machine tool manufacturer in the world.

Haas demonstrated machines and metal cutting technology for aerospace, automotive, medical, mould and die and general machining industries.

More than 25 CNC technology products were on show demonstrate vertical and horizontal machining and turning applications.
