Features and Benefits:
Clausing variable speed 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.
Variable speed head lathes use a belt drive system from the motor to gearbox head. Speed changes are then selected by inverter drive, 4 range speed selection, and potentiometer.
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.

Machine Features:
- 157” between center distance
- 30.7” Swing over the bed
- A2-11 Spindle nose
- 3 Step Inverter drive spindle speeds allow optimum cutting speed for a wide range of machining applications. Speed range 14-1000 rpm
- 20 Hp Spindle Motor for exceptional machining power
- All gears are made from chromium molybdenum steel treated with cementation and precision ground for long life and dependability
