CNC 6-Axis Gear Cutting Machine

Gear size between 8 m to 16 m (26’ ~ 52’)

Gear Cutting Machine (RF-CNC) – SCHIESS BRIGHTON designed and manufactured the largest 6-axis CNC gear hobbing machine in the world recently. SCHIESS BRIGHTON now offers the RF-CNC series gear hobbing machines, which have been improved from the previous models to incorporate the latest state-of-the-art technology. This has resulted in a line of new machines the represent the most modern and efficient gear manufacturing machine tools available today.

The old Schiess AG was located in Düsseldorf, Germany; it was one of the most famous manufacturers of gear cutting machines. It manufactured a total of 600 plus pieces of gear hobbing machine ranging from the gear cutting capacity of maximum diameter of 12 meters to the minimum diameter of 1 meters. Moreover, in the late 1980’s, the old Schiess designed and manufactured the very first and the largest 6-axes CNC gear hobbing machine in the world. This machine has been operating functionally until today in one of the factories located in Germany.

The most significant advantage of CNC gear hobbing machines against its traditional and mechanical gear hobbing models is that the gear cutting production time can be shortened significantly (about 5 ~ 10 times faster), because for CNC models, the carbide tipped hobs with approximately 160 m/min surface speed can be utilized verses only the 16 m/min HSS-cutters for the traditional mechanical models. The CNC machines have additional advantages against its mechanical counterparts; for example, the production of gears can be programmed and recorded within the CNC control system, which can be used competitively; manufacturing gears of more complicated shapes, such as diagonal hobbing and crowning; the structure of the machine is simplified and it is easier for operation and maintenance.

Schiess Brighton continued this series of products of the old Schiess; the RF-CNC series gear hobbing machines applied the latest state-of-the-art technology within the machine tool industry. By building on the foundation of the previous models, and re-engineering this line of machines, the new CNC controlled gear hobbing machines become one of the most modern gear manufacturing machine tools.

This series of CNC gear hobbing machines has 2 models, the maximum gear cutting diameters are: 16 and 10 meters (single indexing); or 14 and 8.5 meters (hobbing). These 2 units are all CNC controlled 6-Axes gear hobbing machines. The relative movements of the axes are described as the follows:
