Bevel gear technology

Bevel gear cutting

Manufacturing spiral bevel gears from bar stock

Turn your INDEX G220, INDEX R200 or INDEX R300 turn-mill center into a gear cutting machine. With this technology, you can produce spiral bevel gears from the bar completely in one setup (front and rear end machining). The proven R series platform, which combines two five-axis machines in one, is an ideal base for bevel gear cutting due to its excellent static, dynamic and thermal properties. Part of our technology package is a special control cycle. Using this cycle, you enter the relevant machine data and correction data for the toothing. 

The tools used are special INDEX cutter heads with carbide inserts. Where you have previously required a special gear cutting machine, you can now use a flexible turning/milling center for production of your bevel gears from bar stock with a minimum of manpower.
