通过采用立方氮化硼(CBN)砂轮在数控(NC)磨床上磨削硬化钢工作靠模的外形,并采用一台专用的数控检验机,从而减少了加工和检验时间,且生产出更加精确的工作靠模。汽车发动机用的凸轮轴通常是在磨床上加工。这种磨床能自动地将一系列工作靠模的外形复制到凸轮轴相应的凸轮上。工作靠模是均布在由整体工具钢棒料加工成的靠模轴上。在
Grinding the hardened steel working profile by grinding with a cubic boron nitride (CBN) grinding wheel with a dedicated NC inspection machine reduces machining and inspection time and produces more accurate Work by model. Camshafts for automotive engines are usually machined on a grinding machine. This type of grinder automatically replicates the profile of a series of working profiles onto the corresponding camshaft cams. Work by die are evenly distributed in the overall tool steel processed into the master axis. in
