What do I use ROGRIND 1.0 for?
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.
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.
