In addition, CBN grinding wheel all carries out grinding to the trunnion and the outer circle of connecting rod neck, thrust surface of crankshaft, thus
It is required that the face R (i.e. hollows) of CBN grinding wheel and periphery both participate in grinding, CBN grinding wheel in use for some time can be with mill
The progress cut and consume so that grinding wheel rust and losing original shape, influence the machining accuracy to connecting rod neck and trunnion, this is just
It needs to modify the face R of grinding wheel and periphery, grinding wheel is enabled to restore good working order, and existing CBN sand
Wheel dressing device modifies grinding wheel using emery wheel, in dressing process, the one end of emery wheel far from electro spindle
The preceding finishing sword of end face modifies the periphery of grinding wheel, the side of the periphery of emery wheel finishing sword to the face R of grinding wheel into
Row finishing, emery wheel is set to side of the grinding machine far from grinding wheel, and the axis of emery wheel is parallel to the work top institute of grinding machine
In plane.This finishing mode there are the problem of include following two points: (1) need to be separately provided the driving device of emery wheel,
Grinding wheel is modified to drive emery wheel far from the side of grinding wheel from grinding machine to from grinding wheel, structure design is multiple
It is miscellaneous；(2) the preceding finishing sword of emery wheel is a finishing face, and face is modified to foreign round with outer circle face contact in the finishing face, is repaired
