tool grinding machines HELITRONIC POWER 400
For maximum flexibility in volume production


Basic Data

The HELITRONIC POWER 400 tool grinding machine is powerful with maximum flexibility for medium to large series.

It stands for top quality worldwide in the production and resharpening of rotationally symmetrical tools. It grinds tools in the diameter range from 3 to 315 mm, a machining length up to 520 mm and a piece weight up to 50 kg.


Gantry design

The WALTER gantry design with its heavy weight and extreme rigidity converts the high dynamics of the digital drives into grinding precision with minimal vibration.

Ball screws

The tool grinding machine has three linear axes X, Y, Z with ball screws. The max. traverse speed is 15  m/min.

4/8 Grinding wheel changer

As option there is a grinding wheel changer 4/8. It has a capacity of up to 8 grinding wheel adapters and thus multiplies the grinding wheel capacity of the HELITRONIC POWER 400.

Motor spindle (option)

The optinal powerful direct driven motor spindle with a spindle end is equipped with a liquid cooling system. The spindle power is  26 KW.

Belt-driven spindle with two spindle ends

The powerful belt-driven spindle with two spindle ends can accommodate up to 3 electrodes resp. 6 grinding wheels with a maximum diameter of 254 mm and has a maximum peak power of 24 kW.

Laser Contur Check

The new, innovative Laser Contour Check option offers an intelligent measuring system integrated directly in the tool grinding and eroding machine for the highly accurate, non-contact measurement of various tool parameters on cylindrical tools.
