Different Types of Spindles

Spindle Types

Belt Driven- (similar to basic spindle design)

Spindle shaft is held with bearings

Supported by Spindle housing

Spindle shaft uses tool taper, drawbar, and tool release system

Power and rotation uses external motor


Reasonable Cost- relatively low

Variety of Characteristics- specifications can be modified, vary speed ranges

High Power and Torque Possible- large motor can be used

Integral Motor- does not rely on external motor, motor is part of shaft and housing

Rotate at higher speeds as a uniform unit without limitations

Spindle shat includes motor element and tooling system

Non ventilated, ventilated, liquid cool


Smaller machine inventory, require less space than belt driven

More powerful the motor the higher the speed
