tool grinding machine HELITRONIC MINI AUTOMATION
For series production


Basic Data

The 5-axis CNC HELITRONIC MINI AUTOMATION tool grinding machine is the first choice when it comes to the highest productivity and quality expectations in volume production. For rotationally symmetrical tools and production components with maximum 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.

Ball screws

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

Torque motor

The tool grinding machine has a workpiece holder A as a torque motor with max. 750 min-1 for the extended range of functions, such as profile grinding or background lines.

Robot loader

The HELITRONIC MINI AUTOMATION is equipped as standard with 1,500 tool slots on a Fanuc robot loader.

Glass scale

The HELITRONIC MINI POWER has glass scales with a linear resolution of 0.0001 mm for highest positioning accuracy.

Belt driven 9 KW spindle

The tool grinding machine has  a  9 KW belt driven spindle with two spindle ends. The different grinding wheel sets are assigned together with the wheel data of the respective spindle.
