Whirling milling (or trochoidal milling) stands for highly dynamic milling with a high chip volume. Until now, this function was only optimal for slotting. HEIDENHAIN is changing this with a new optional feature for the TNC 640: Optimised Contour Milling (OCM) makes the idea of trochoidal milling available for a much wider range of applications. In addition to roughing open and closed pockets and islands of any shape, OCM also offers cycles for finishing bottoms and side walls.
Like whirling milling, OCM limits the wrap angle and allows milling with the entire cutting edge length. With OCM, the user can programme any contours directly on the TNC 640 in the usual workshop-oriented way. The control automatically calculates the best possible tool paths to ensure that the cutting conditions are constantly maintained. Machining always runs with the optimum cutting values. This not only significantly increases the machining speed - tool wear is also noticeably reduced.
Advantages of vortex milling with OCM.
Less milling pressure for thin-walled components
Higher chip volume
Lower processing time
Better machining of hard materials
Lower heat generation in the component
Lower tool wear
We would be happy to show you the advantages of vortex milling using a practical example in our demonstration centre in Meppen.

What do the Olympic Games have to do with metalworking? At first glance, not much. Some might immediately think of the customary bite that winning athletes take out of their medals. But it’s worth taking a closer look – because the right equipment can make all the difference when it comes to those crucial hundredths of a second. When German athletes compete for medals at the Olympics, in many cases there is a great amount of development and manufacturing work behind the scenes. At the Institute for Research and Development of Sports Equipment (FES) in Berlin, this also includes CNC technology from HEDELIUS Maschinenfabrik in Meppen.
(PDF | DE) Machining large workpieces flexibly whilst reducing unproductive downtime: The TILTENTA 9-2600 with MARATHON LR810 combines the advantages of a universal travelling-column machine with high-performance heavy-duty automation. During the day, the machine remains freely accessible for the manual machining of large and complex single parts, whilst the automation system enables additional productive spindle hours outside regular shifts. Up to ten pallet locations and a transfer weight of 2,000 kg provide the ideal conditions for this.
Steingross Feinmechanik GmbH & Co. KG specialises in the manufacture of sophisticated CNC-turned and CNC-milled components – from prototypes through to series production. Founded in Berlin in 1990 by Uwe Steingross, the company sees itself as a comprehensive system supplier of CNC machining technology and combines modern milling and turning processes with surface treatment, precision finishing, final assembly and design consultancy. Since 2019, Steingross has been relying heavily on HEDELIUS as a technology partner – including for the automation of its manufacturing processes.
