2025 Clausing C1330SJ – Geared Head Lathe with 13” Swing over Bed, Straight Bed Engine Lathe

Clausing geared head lathes are the industry standard. The quality built into every machine translates into real long-term performance for your application. The removable gap plate allows for large face plates to be mounted onto the spindle nose for various turning applications. Camlock Spindles, a wide range of spindle speeds, full length rear splash guard with coolant system, and inch/metric threading make this machine a must have for any machine shop.

Geared head lathes use a belt drive system from the motor to gearbox head. Speed changes are then selected by shifting gear levers into a certain configuration recorded on a legend plate.

Three phase voltage refers to three individual lines that connect to and run voltage through the motor. Each line alternates in a sequence as it reaches its voltage peak. This provides for a more stable flow of voltage and more horsepower to the machine.
