The Driving Flange was designed in cooperation with one of the leading power tools producers. The part is absolutely brand-new. It has never been produced before by any other technology. The original conception, including prototypes, was designed for CNC machining from conventional bars. Yet, the adaptation to PM technology provided a huge price reduction in comparison to traditional technology.
The serial scale production provides a cost effective solution to the customer. The new design of the driving flange represents a truly new approach in cutting and brushing disc clamping action. We expect to spread this concept worldwide during next few years, including complete replacement of old generation of a flange, which uses an internal thread to create a clamping force. From an end user point of view, the main contribution is the reduction of the time which is needed to replace an already worn disc – within a few seconds instead of one minute. The Driving Flange is compacted on a CNC hydraulic press using all three upper axes and all four lower axes. To ensure a higher hardness of the surface layer and tough core of the part, case hardening is used. CNC turning is used to ensure a precise internal diameter, and CNC milling is used to create four counter bars for screws
