Why doesn't the motor reside on the spindle?

The 2-stroke, 4-stroke or 400 V electric motor drives a separately mounted V-belt pulley which in turn drives the grinding shaft.

  • This is reducing vibrations,
  • produces a more homogeneous cross section,
  • exposes the grindstone to less wear and
  • protects the motor from impact.
  • At every step of the grinding process, a perfect view of your work is retained.

How do I set / replace the cup wheel?

A fixing nut on the grinding spindle sets the bottom limit of grindstone motion. Aim for a spindle stiffness setting which stops the cup wheel from turning downward by its own weight and the machine vibrations while maintaining a smooth spindle movement.

 

There is no vertical play of the cup wheel. When setting the cup wheel, the handwheel's rotary motion thus fully translates into a change in height equivalent to the fine-tuning feel needed for finishing.

 

The nut in the middle of the grinding shaft makes cup wheel replacement quick and easy.
