Universal shifting milling head for soft and hard machining of screws
The K 200 hobbing machine is equipped with a high-performance universal shifting milling head that is extremely small and set up for hobbing of spur gears and milling of single-start and multi-start screws. Its compact design also makes swiveling the milling head under the tailstock in order to mill screw geometries possible. The hobbing machine is mostly used by manufacturers of step-down gears and their suppliers.
Utilizing the machine’s state-of-the-art drive technology, the K 200 hobbing machine threads at a level of precision perviously achieved only through griding applications. With this quality, the K 200 hobbing machine is also particularly useful for the manufacture of safety-relevant components or aerospace engineering. This high-precision gear-cutting is decisive, as work gear drives with crossed axes have generally been produced using an immersion method. Nearly all standard hobbing machines are suitable for this, although they cannot reach this level of precision. A precision of DIN7 or DIN6 is mandatory in the aerospace sector, however (e.g. for wing flap adjustment).
The K 200 hobbing machine is able to meet these specifications, above all because of the tangential hobbing option, the use of a special tool, and development of the corresponding software.
Key points in milling of screws:
- Production of screws for step-down gears
- Production of screws using hard skiving
