The Haas Toolroom Lathe series offers versatility in turning diameters to 30" and lengths to 60". With a functional range from manual turning to full CNC, Haas Toolroom Lathes feature 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 Toolroom Lathe series operates in four modes – from manual to full CNC.. In all modes, the Haas control provides extremely accurate digital read-out (DRO) of position, displayed to 0.0005" when using the manual handwheels or to 0.0001" 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 Toolroom Lathe series performs simultaneous linear interpolation for both axes using a single handwheel. 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, 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 Toolroom Lathe series – 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.
