WALTER HELITRONIC DIAMOND - The Machine For Grinding PCD Tools

  • For PCD grinding power

The WALTER HELTRONIC DIAMOND is the door to the future of PCD tooling – based on the Helitronic Vision

The market for polycrystalline diamond (PCD) tools is growing fast in both the metal and woodworking industries.  The reason is simple: PCD tools offer up to 300 times the life of normal tungsten carbide tools.  If you want the competitive edge in making these tools—explore the Helitronic Diamond’s unique approach and features.

With its Two-in-One concept, the HELITRONIC DIAMOND opens the door to the future market of PCD tools specifically for metal machining.

Eroding of PCD and conventional grinding on ONE machine according to the motto: Eroding where necessary - Grinding where possible all with surface qualities of RA up to 0.1 µm. 


  • Stock removal up to 2.6 times faster than competing machines
  • Surface finish down to Ra 4 µin. (0.1µm)
  • Erosion machine and two-spindle grinder—Enter the growing PCD market without dedicating a machine to it
  • Contour EDG for a wider variety of tools
  • Easy setup on the machine or an office PC so machine stays productive
  • Direct drives in all axis with incredible acceleration & speed (up to 2,000 IPM)
  • Patented “acceleration proof” mineral casting (machine weight 16,500 lb.)
  • HELITRONIC TOOL STUDIO software combines ease of use with infinite flexibility
  • Automatic Smart Probe quickly measures and positions the cutting edge and compensates for any skew or bow in the PCD insert
  • Optional autoloader for up to 504 tools
