With wheel changer as standard equipment

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.
