Features and Benefits
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.
