Features and Benefits
Toolroom lathes are used for 5C collet work and precision finishing operations. They are capable of achieving spindle runout within 50 millionths on an inch or better.
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.
