BVGM

The series product is a high reliability, high accuracy, good efficiency metal cutting machine. It is realized rough, finely machining for inner tooth straight gear or taper gear by C axis, Z axis simultaneously feed together with highspeed rotating with round tool disc.
It is performed machining roughly and finely for inner and outer straight gear or inner race profile of taper gear on the swivel supporting parts.
The series is adopted advance metal cutting method. It is realized rough, finely machining for inner tooth of straight gear or taper gear by C axis, Z axis simultaneously feed and forceful milling with round tools disc.
It is international advanced metal cutting tools for single tooth machining, so production efficiency can be improved 10 times than common gear hobbing machine.
CNC system is SIEMENS 828D.
