Due to its robust design and high precision, the series 500 motor grinding spindle is suitable for all applications related to state-of-the-art grinding technology. Our grinding spindles are manufactured from special materials ensuring a high dimensional stability even at extreme application conditions. Only high-­precision bearings installed under ­preload are used as bearings. The concentricity on the taper is < 0.002 mm.

Rotation
Thanks to our locking device on the ­taper, our grinding spindles can be ­operated in CW and CCW mode. ­However, the use of our original accessories is a prerequisite.

Lubrication
Grease life-time lubrication

Motor
The motor can be controlled via a frequency converter up to max. 100 Hz.
The motor is connected to the spindle shaft via a Rotex coupling.

Sealing
The tool end is sealed by means of a specially tested labyrinth seal. It protects the spindle bearings against soiling. The spindles can be used horizontally and vertically alike.
