For maximum flexibility in volume production
Basic Data

The HELITRONIC POWER 400 tool grinding machine with wheel changer 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.

Grinding wheel changer

The standard equipment includes 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

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