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.

On the high-precision Multigrind CA high-tech grinding machine, the complete workpiece can be machined in a single clamping operation. This grinding strategy is unique, and the process design is innovative. The Multigrind CA produces maximum precision and enormous time savings with minimum space requirements. The process guarantees repeatable results in series production and is also ideal for prototyping and one-off production.

From precision tools and turbine blades to gearbox shafts and knee implants: You can grind just about anything on the Multigrind CA. The center features the Adelbert Haas Multicube design with a cubic mineral composite base and symmetric arrangement. There are no mechanical surpluses and no projections. Tool changers and automation make your grinding projects cost-effective and reliable.

The Multicube is made from a thermally stable mineral composite with cast-in X- and Y-axes and a central grinding unit. There are no surpluses, little thermal expansion and vibration dampening for maximum stability. Thanks to its kinetic arrangement, the grinding wheel lies in the machining center of the Z-axis. Located at the top, the Z-axis ensures significantly reduced paths and faster machining – in an impressive working range of 630 mm (X-axis), 345 mm (Y-axis) and 430 mm (vertical Z-axis).
