Features and Benefits
Engine lathes are used for heavy-duty work and offer heavy casted machine bases with built-in coolant systems and foot brakes. The Swing range on these lathes is from 13" and larger.
Geared head lathes generally feature drive belt(s) from the motor to the headstock. Speed changes are made by shifting gear lever combinations in the headstock.
Three-phase refers to three individual lines (coils) that connect to and run voltage through the motor. Each line alternates in a sequence as they reach their voltage peak. They provide a more stable flow of voltage and more horsepower to the equipment.
