For maximum flexibility in volume production

The HELITRONIC POWER 400 with wheel changer is the high-performance top version with maximum flexibility for mid-sized to large series. Around the world, it stands for top quality in the production and resharpening of rotationally symmetrical tools. Permissible diameters range from 3 to 315 mm, machining lengths can be up to 520 mm and weight up to 50 kg.

For the production and resharpening of rotationally symmetrical tools in a single clamping cycle, even with complex geometries. Working together with the grinding wheel changer, a variety of loading systems and the motor spindle, it sets standards in productivity and flexibility.

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.

 

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.

 

Ball screws

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

 

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.

 

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.

 

Laser Contour 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.
