Machining precision in the face grinding of a groove

2003/7/20In face grinding using a cup CBN quill, the grinding force is rapidly increased and wheel life is short because the coolant does not reach the grinding points easily. The CBN grain size, coolant supplying method and the tilted spindle grinding method have been discussed, the larger CBN grain size and hollow shank coolant supplying are beneficial to wheel life [1], [2], [3] .Get price
