Abstract:
End face burn occurred when grinding CBN grinding wheel in grinding crankshaft journal and end face. In condition that adjusting the cooling system does not solve this problem, the structure of grinding wheel is redesigned by modifying the end surface and grain type. The newly designed and prepared electroplated CBN grinding wheel is tested on grinding experiment. Results show that at the same cooling system, the new electroplated CBN grinding wheel could solve the problem of burns in the mentioned process.
