Micro Lathe Offers Compact Footprint
The Grizzly Industrial G0745 Micro Metal lathe is designed for turning small workpieces. With 4 1/4" swing over bed and 6" distance between centers, the lathe is well-suited for jewelry, model-making and hobby applications.
The compact machine is built on a precision-ground cast iron bed and offers a footprint of 14" × 5 1/2", enabling benchtop use. The tailstock quill travel measures 7/8" and the cross-slide travel is 1 1/2". A single-phase, 110-V motor provides 150 W (1/5 hp), and the variable-speed spindle ranges from 100 to 3,800 rpm. The lathe is equipped with a 2" three-jaw chuck, a chuck safety shield, a tailstock dead center and a cross-slide mounted toolholder.
A leading manufacturer of high-performance valve train components installed a twin spindle/twin-turret lathe to bring camshaft machining work in-house. Here, the company explains how it has become more effective using its multifunction lathe to produce small batches of custom racing camshafts.
This manufacturer’s use of live-tool lathes overcomes labor cost in various ways. One of the latest sources of savings involves bringing another operation—hobbing—into these machines. INCLUDES VIDEO.
The additional rotary milling axis on these machines allows them to complete many types of complex parts in a single setup, but these machines have gained a reputation for being difficult to program. Today’s CAM software, however, eases the programming challenge significantly.
