CNC tool grinding machine model NEXT

CNC TOOL GRINDING MACHINE TTB NEXT

COMPACT HIGH PRECISION TOOL GRINDING MACHINE

Continuity in the kinematics - Refined and optimized in the details.

The NEXT model is the latest result of more than 30 years of experience in the grinding field for boring, milling and gear cutting tools. A high precision tool grinding machine with 5 or 6 axes and 4 or 5 spindles.

Speed, accuracy, repeatability, compactness, and reliability are the main attributes of the NEXT model.

Due to exceptionally short setup time, this machine is suitable to produce small batches. But even with large quantities or long cycle time, a constant high quality in the µm range is guaranteed.

Tool data

  • Min. tool diameter Ø 0.02 mm
  • Max. Tool diameter Ø 14 mm
  • Max. grind length 150 mm
  • Resharpening Ø 3 - 25 mm

Tools with a diameter of 0.02 to 14 mm can be produced with the machine in perfect quality. Resharpening of tools up to Ø 25 mm is possible without any challenges.
