Gear hobbing machines, horizontal
The Model 300 hobbing machine combines the latest advancements in machine technology with maximum versatility and flexibility in an area of only 8 m2. The 9 CNC controlled axes on Model 300 allow all possible gear cutting applications to be accomplished. The machine bed is a composite epoxy material that incorporates roller bearing slides in all linear motion axes. This provides the highest static, dynamic and thermal stability. A closed box machine design prevents deflection of the tailstock due to high clamping pressures and cutting forces. The unique KOEPFER design concept of symmetrical distribution of cutting forces ensures a long machine life with consistent part quality. The slant design of the hob head allows optimum chip flow for dry or wet cutting.
