Features and Benefits:
Clausing/Colchester Magnum Large Capacity Infinitely variable speed manual lathes are the industry standard for lathes. 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. Rugged construction, consistent quality in design and production, along with human engineering makes the operator more efficient, making this lathe a cost effective investment. You will get unbelievable machine performance and operational longevity with the Clausing/Colchester Geared Head Lathes. Optional spindle bore sizes make these machines a best fit for large turning applications.
These Variable Speed lathes use a State-of-Art AC Spindle Drive to control the motor. A belt drive system from the motor to gearbox head. Speed changes are then selected by shifting gear levers into one (1) of four (4) locations then adjusting a pot control knob to adjust the speed output.
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.
