The efficient eroding and grinding machine


Basic Data

The HELITRONIC DIAMOND EVOLUTION  tool eroding machine can erode and grind tools  in one setting. 

The machine is a highly efficient solution when it comes to the eroding of PKD/CBN material tools and the grinding of high speed steel/carbide tools in one single clamping cycle on a minimal footprint. It handles tools with a diameter of 1 to 165 mm, a tool length up to 185 (255) mm and a piece weight of up to 30 kg.


Gantry design

The WALTER gantry design in cast iron with its good damping properties ensures excellent tool surfaces.

Linear axes

The tool eroding machine has three linear axes X, Y, Z with ball screw. The maximum travel speed is 15 m/min.

Belt-driven spindle

The HELITRONIC DIAMOND EVOLUTION has a HSK 50 belt/driven spindle with two spindle ends for up to three  electrodes and up to three  grinding wheels, alternatively up  to six grinding wheels.

Fine Pulse Technology

The eroding machine is equipped with the latest eroding technologies for a stable and fast eroding process. This ensures an excellent surface finish and minimal chipping.
