Rapid Traverse Rates
The following tables show rapid traverse rates, in metric and English, for the axes. The
Spindle Max RPM values are listed in some tables to differentiate between machine types.
Where NA is indicated, the axis is not available for the machine model.

Servomotors
Axis velocity, position, and travel direction are controlled using AC servomotors along
with the CNC control. These motors are enclosed, transistor-driven, and self-cooled.
Because they are designed without brushes, the motors are free from flashover and
commutation loss.
The servomotors power the ballscrews by belt drive on the X and Y axes, and by direct
drive transmissions on the Z axis.
Ballscrews and Bearings
The precision ballscrews are the double ballnut type (the VM series machines have a
single nut anchored on both ends of each ballscrew). The ballscrews are hardened and
ground to minimize "drag torque" and reduce backlash.
The axes positioning drives are supported at the drive-ends by ABEC-7 class bearings.
