Gearhead Lathes

Gearhead lathes use hardened and ground gears in the headstock to transmit power, delivering higher torque, more speed selections, and greater rigidity under heavy cuts. Belt drive lathes use pulleys and belts, which are quieter and less expensive but can slip under load and offer fewer speed options — making them better suited for lighter, precision work.

The three common types of lathes are engine lathes (manual, general-purpose machines for turning, facing, and threading), CNC turning centers (computer-controlled for high-precision and high-volume production), and turret lathes (equipped with a multi-tool turret for repetitive production work). Gearhead lathes fall within the engine lathe and CNC categories.

Clausing gearhead lathes are available with spindle motor power ranging from 3 HP up to 75 HP depending on the model series. The C-Series engine lathes cover 3 HP to 50 HP, while the CNC lathe series offers 50 HP to 75 HP inverter-driven spindles — accommodating light general machining through heavy-duty industrial turning.

Clausing gearhead lathes feature a universal gearbox supporting inch (imperial), metric, diametral pitch (D.P.), and module pitch (M.P.) threading. For example, the 8044VSJ supports 73 inch pitches, 51 metric pitches, 27 module pitches, and 27 diametral pitches — giving machinists broad flexibility for diverse threading applications.

Yes. Both the Clausing Engine Lathe C-Series and Clausing CNC Lathe are specifically designed for oil field, oil country, shipbuilding, and marine industry applications. With swing over bed capacities up to 80 inches, spindle bores up to 24 inches, and distances between centers up to 488 inches, they handle large-scale components common in these industries.

Clausing engine lathes include a one-year warranty backed by the Clausing Service Center, which stocks over 80,000 parts with 95% of orders shipped within 24 hours. The 8044VSJ Variable Speed Lathe additionally provides a 4-year parts and labor warranty on the AC inverter drive. Phone and on-site technical support from qualified technicians is also available.
