RTM – CNC Rotary Table Grinding Machine

RTM – CNC Rotary Table Grinding Machine with horizontal chuck for grinding circular saws or similar workpieces.


The RTM-CNC with horizontal workpiece loading for circular knives, circular saws and similar workpieces. Extreme short cycle times because of the digital servo drives with idle speed up to 30m/sec (100ft/sec).

As an optional feature a robotized feeding and automation system is available.

  • High precision due to preloaded playfree linear roller bearing guides
  • Infinitely variable regulation of the grinding wheel drive with programmable constant peripheral speed
  • Sensor controlled contact of grinding wheel with workpiece to avoid “air grinding”
  • Easy programming with CNC-control SINUMERIK
  • Integrated dressing attachment for the grinding wheel, CNC controlled
  • Automatic compensation of the grinding wheel wear
  • Grinding of different angles with 2 CNC axis


Optional features

  • Infinitely variable speed of the workpiece chuck with constant surface speed (programmable).
  • Dressing attachment with diamond coated dressing rolls for short dressing cycle
  • Magnetic workpiece chuck
  • Automatic feeding system with Scara-Robot
