KOEPFER K 200 Gear Hobbing Machines
The gear hobbers of the K Series for precise gear hobbing have a machine body made of high-grade MINERALIT® polymer concrete, which provides excellent damping properties. This results in better surface quality and long tool service lives.
The KOEPFER gantry loader, equipped with V-grippers, forms the basis of the automation system of the Gear Hobbing Machines. A number of blank and finished component magazines are available to cover a great variety of components. A combination of "ramp" and belt conveyor constitute the standard solution. Long-time magazines, like the recirculating storage conveyor, make sure that the gear hobbing machines are running for a number of hours and are not only suitable for both wheel- and shaft-type components, but can also be reset without much effort.
The capacity of a gravity-based magazine, and thus the autonomy of the hobbers, can be greatly enhanced with the use of multiple feeding rails. The triple distributor system can also be used as a twin or even a single distributor. Moving the supporting blocks for the distributor levers provides practically unlimited numbers of settings to accommodate different workpiece lengths.
