Thielenhaus Microfinish says it has introduced a trendsetting innovation on the path to Industry 4.0: based on the proven MicroStar platform, the machine-tool manufacturer has managed to develop the first self-regulating flat-finishing machine, MicroStar iQ. Until now, no reducing processes were possible with parameters such as flatness.

The eight-station machine for combination processing does not just ensure highly precise workpieces, but consolidation of the process stream. In the area of active magnetic spindle technology, the magnetic fields of the bearings retain the spindle both radially and axially, and perform the feed motions. The MicroStar is equipped with a synchronous spindle, which is capable of varying and/or oscillating highly dynamic speeds during the process. Due to the speed variation, the tool can always be maintained within an easy-cutting range. HyperFinish processing is also possible with this system by overlapping the main oscillation with an additional high-frequency oscillation.
A new HyperBrushing process that was developed especially for the machine ensures equal or even better results than those achievable by a high-pressure deburring unit, which can thus
be omitted from the whole process to save costs, says Thielenhaus. This deburring technology with special kinematics of the brushes improves the symmetrical rounding ratio of the flat surface to the casing and ensures more constant deburring results. According to the company, this is particularly important in the case of holes in components used for injection technology, which may be subjected to pressures of more than 2000 bar.
