Spindle Technology – Series 800

Spindle Technology – Series 800

Motor spindles

Main features series 800

  • High frequency motors with liquid cooling
  • High bearing rigidity
  • Concentricity on the mounting taper < 0.002 mm
  • Preloaded spindle bearings

The 800 series motor spindle conceals a powerful spindle system with a liquid-cooled drive which has been designed in line with the latest developments. Because of its precision and stability, this spindle is particularly suitable for all processing tasks that require higher cutting speeds. We manufacture these spindles exclusively from special materials that meet these high demands. The mounting taper concentricity is < 0.002 mm.

The technology of the 800 series


We only use high precision preloaded ball bearings with ceramic balls. We thereby achieve a better wear behaviour and higher maximum speeds.

Rotational direction

The anti-twist lock on the mounting taper allows our grinding spindles to be operated clockwise and CCW. This requires use of our own brand accessories.


Lifetime grease lubrication


It is driven by a liquid-cooled, variable induction motor.
A frequency converter is used to control the motor up to its maximum speed.
The motor is protected by KTY or PTC Sensors in the motor winding.


Heat is dissipated using an integral cooling circuit near the motor winding.


The tool side is sealed by a specifically proven labyrinth packing. This protects the spindle bearings against soiling.
Spindles can be installed either horizontally or vertically.
