2025 Clausing C1550J – Geared Head Lathe with 15.25” Swing over Bed, Gap 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 configurations 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.
