HELITRONIC MICRO grinding machine for small diameters
High-end for smaller Tool diameter


Basic Data

The tool grinding machine HELITRONIC MICRO with C.O.R.E.-Technology produces and sharpens rotationally symmetrical tools and production parts with smaller diameters. It grinds tools from a diameter of  0.1 mm in production and in re-sharpening operation from a diameter of 3 mm. The maximum diameter is 12.7 mm, the tool length isup to 220 mm and the piece weight is up to 12 kg.

New with Laser Contour Check option!

C.O.R.E. Panel


Mineral cast machine bed

The HELITRONIC MICRO has a mineral cast machine bed and is specifically designed for this application. The machine provides you with great vibration damping, temperature sensitivity, drive dynamics and ultimately grinding precision.

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.


All five CNC axes are equipped with linear or torque drives and are controlled by the integrated high resolution measurement systems. These create exact movements while at the same time creating high dynamics.

Robot loader

The HELITRONIC MICRO has a 6-axes machine-integrated robot loader that minimizes charging times. The capacity is up to 1,500 tools.

Workpiece axis A

The fast rotating workpiece axis A with max. 3,000 min-1 gives the HELITRONIC MICRO - especially with step tools - a precise profile grinding capability.

Motor spindle

With three motor spindles for up to 12 grinding wheels, the HELITRONIC MICRO is flexible in its application. Motor spindle 1 with 6.5 KW spindle power for grooves. Motor spindle 2 and 3 with 4.3 KW spindle power for the grinding of geometry.
