北京第二机床厂与北京航空航天大学合作开发的ＭＫ8332型数控凸轮轴磨床于 6月 2 9日通过鉴定。鉴定委员会认为 ,该新产品采用国产高档数控系统 ,实现凸轮曲线轮廓面的精密磨削 ,从根本上改变了凸轮型面的传统靠模加工工艺。该机采用了ＣＢＮ新型磨料的高速磨削工艺。机床采用 MK8332 CNC camshaft grinding machine developed by Beijing No. 2 Machine Tool Plant and Beijing University of Aeronautics and Astronautics passed the appraisal on June 29. Accreditation Committee believes that the new product using high-end domestic CNC system to achieve the cam profile contour grinding, fundamentally changed the cam surface of the traditional model machining process. The machine uses a CBN new abrasive high-speed grinding process. Machine used
