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.

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.
From 15 to 19 September 2026, HEDELIUS Maschinenfabrik GmbH will be presenting three automation solutions at the AMB in Stuttgart, designed to meet a range of requirements in single-part and small series production. The focus is on productive manufacturing concepts that maximise spindle running time, reduce set-up time and give manufacturing companies greater flexibility in handling changing orders. A particular highlight is the premiere of the new MARATHON LR810 heavy-duty automation system. The systems can be seen in action in Hall 10, Stand D71.
Milling and turning in one clamping: In the new product video, the TILTENTA MILLTURN shows what modern complete processing looks like today. The continuous machining process reduces reclamping operations, increases process reliability and creates the basis for the economical and precise production of complex workpieces. Experience the TILTENTA MILLTURN in practical use and discover the advantages of economical and process reliable complete processing on one machine.
