The Curvic coupling from the aviation sector is a critical component used in helicopters. Previously, the external helical gearing was manufactured on one machine and the curvic coupling gearing on a second machine. The external and internal cylindrical grinding was then carried out on a third machine in two consecutive process steps.

Forming tools are expensive, often made from carbide and tool steel. Carbide grinding is often the first choice today because customer requirements have increased and continue to increase in terms of complexity, dimensional accuracy and reproducibility. Apart from that, production must also be significantly more economical.

The Haas Booth C50 Hall 10 at GrindingHub will include the Multigrind Radical, Multimation and the Multigrind CB XL series. In addition, the Multigrind CU, the Multigrind CA and the Multigrind CB will be featured during the show.
