Electronic lathes for complex machining

Modern Machine Shop, Feb, 2005 by Christy R. Bramlet

The company introduces its Liberty series Touch Turn electronic lathes, giving those machinists with little or no CNC experience the ability to perform normal manual operations with electronic handwheels. Operators can also achieve complex machining using an intuitive touchscreen system.

Using CNC technology, the lathes are developed to enhance accuracy and reduce work time. They can be operated manually (like any conventional lathe) or through semiautomatic cycles via Fanuc control.

Sizes range from 13" x 40" to 26" x 200". As many as 40 different operations can be saved and executed upon demand. There is also capacity for 15 calibrated tools. Accessories used with manual lathes, such as a taper attachment, tracers and a threading gearbox, are no longer required. Finishes are produced through a customized double-belt drive system to the Fanuc variable speed main drive and a three-bearing spindle that employs angular contact ball bearings. The control incorporates an RS-232 port for communicating with a remote PC, allowing the download of CAD/CAM or existing programs to the Touch Turn control for execution.

Various cycles for OD and ID turning, facing, threading and grooving that require interpolation of two axes are displayed on the touchscreen in the form of icons. No CNC training or knowledge of G codes is necessary. In addition, the screen can display operating data including axis position, feed rate, spindle speed, tool selection and more.
