How does ROGRIND 1.0 improve ergonomics while grinding?

Pivot the machine by up to 90° for grinding the sides. To find your most ergonomic posture, lock the tilting handle at any point within a 60° swivel range.


Ease of use is further enhanced by the machine's modular design which allows you to set the machine to your preferred way of working:

  • Attach the soft-grip tilting handle on the left or right side in work flow direction according to personal preferences.
  • Attach the optional extra handle to the middle of the drive motor's fan case to improve the way you guide the machine and to optimise your posture.
  • Install the mounting kit of the air filter protection to improve the feeding of intake air and to reduce the dust concentration in the exhaust air.

What do I use ROGRIND 1.0 for?

  • For restoring the profile of welded joints
  • For deposit-welded tread and lateral faces
  • On free rural lines
  • In urban areas (electric version)
  • In tunnels (electric version)

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 reduces vibrations,
  • produces a more homogeneous grinding pattern,
  • exposes the grindstone to less wear and
  • protects the motor from damage by hits.
  • At every step of the grinding process, a perfect view of your work is retained.

How do I set / replace the grinding 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 grinding wheel. Therefore, 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 grinding wheel replacement quick and easy.
