The 8 station machine for the combination processing doesn’t just ensure 100% compliance of all drawing dimensions for highly precise workpieces, but also the consolidation of the process stream. It generates significant cost savings. Oscillation sensors control the sensors and also the quality of the processes. 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 kept in an easy-cutting range. Hy-perFinish 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 this 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. This deburring technology with the special kinematics of the brushes improves the symmetrical rounding ratio of the flat surface to the casing and ensures more constant deburring results. That is particularly important in the case of holes in components used for injection technology, which may be subjected to pressures of more than 2,000 bar. Before the workpieces leave the machine, they are cleaned in a cleaning station with dry ice and an extraction system and then finally, their flatness is measured.
Based on the measured results, in the event of deviations from the drawing specifications, the program can make immediate readjustments in conjunction with PowerTilt in a closed control loop. PowerTilt automatically adjusts the flatness and the cross cut of finish stations. With EasyTilt calculation software is also available for highly precise adjustment of finishing units of the workpiece drawing.
Due to “gauging inside” with feedback of the results to the finishing units and monitoring the oscillations, measuring room capacity is also saved and the operator is significantly unburdened as s/he no longer needs to make quality-related adjustments.
In the case of frequently changing workpiece versions, the extremely shortened set-up times also have an incremental affect on output.

Thielenhaus Microfinish
Thielenhaus Microfinish, a division of the German Thielenhaus Technologies GmbH, has been building high-precision, high-productivity machine tools for over 100 years. In the last 70 years, Thielenhaus Microfinish has become the leading manufacturer of extreme-precision machine tools for Microfinish/Superfinish and double-disc grinding applications.
Microfinishing, also known as superfinishing or short-stroke honing, is the ideal machining process for achieving extreme precision surfaces and component geometries, and removing amorphous surface layers in the magnitude of 2 µm. Honing stones, cup wheels and microfinishing tape or film can be used to generate surface roughness or geometrical accuracy within a previously defined window that often spans a few tenths of a micron. Indicated below are a number of parameters which can be optimized using Microfinish:
With facilities in Europe, America and Asia and a worldwide service network, Thielenhaus has adapted itself to the market conditions and to the customer needs all over the world.
Commitment to quality: Thielenhaus machines are employed by leading manufacturers across the world for a good reason – their high reliability, productivity and production quality. Thielenhaus continuously pushes the limits of precision machining, enabling its customers to achieve workpiece qualities that were previously impossible.
All solutions from a single source: Extreme precision is the specialty of Thielenhaus, and over the years the manufacturer has built the world’s largest portfolio of Microfinish solutions, ranging from industrial equipment for large and small manufacturers to just-in-time tool delivery and other services. When it comes to Microfinish Thielenhaus is the one-stop shop.
The flexibility of Thielenhaus is its customer’s advantage: The manufacturer adapts the machine solutions to the customer’s component, loading/unloading preferences, cycle time requirements and other specific needs. The modular design of the machine platforms accommodates even tricky components.
New challenges and innovation are the passion of Thielenhaus: They are proud of their 430+ patents in surface finishing technology as well as of numerous market-leading platforms and pioneering innovations. Thielenhaus constantly seeks to improve the machining concepts, always keeping in mind the challenges of tomorrow.
Customer support all over the world: With customer service locations in six countries and service agreements with a network of agents and distributors, Thielenhaus is able to provide quick service on short notice practically anywhere in the world. The customers also benefit from a 24/7 hotline and Online Direct Service.
Thielenhaus is known as a highly experienced problem solver: Anyone can be a problem solver, but with more than 70 years of developing Microfinish solutions, the Thielenhaus staff have probably seen and solved more Microfinish problems than anyone else in the industry. When it comes to splitting microns, the Thielenhaus in-depth knowledge of the microfinishing process is unsurpassed.
