CNC tool grinding machine model NEXT



Kinematic continuity – specified and improved in the details.

After 30 years of experience in the grinding industry, the NEXT model ist the latest result of our grinding know-how. Highest precision in a tool grinding machine with 5 to 6 axes and 4 to 5 spindles, designed by our milling, boring and gear cutting experts.

The NEXT combines properties like precision, speed, compactness, accuracy and repeatability in one single CNC grinding machine.

Thanks to its remarkably quick setup times, this machine is well suited for smaller batches. Still, larger numbers and long cycle times guarantee for an astonishing precision. And the quality and continuity in the µm range is ensured aswell.

Tool data

  • Maximum diameter of the tool Ø 14 mm
  • Minimum diameter of the tool Ø 0.02 mm
  • Maximum grind length 150 mm
  • Resharpening Ø 3 - 25 mm

The NEXT is capable of producing tools between diameters of 0.02 to 14 mm with total precision and in perfect quality. It is possible to resharpen tools of up to Ø 25 mm without any issues.
