英国Jones&Shipman机床制造厂目前可提供一种镀有磨料的刀具,称之为微量饺刀,微量铰刀用于普通珩磨后铰削,前孔光洁度要求不严,经过铰削的孔精度达0.005mm,并无废品。这种微量铰刀是由带有螺旋槽的,可调整的套筒与带有与套相配的锥度心轴组成。铰刀套尺寸可根据被加工孔的尺寸精确选择。因铰削余量很小,故铰后可以校正孔的几何形状误差。套简表面镀有金刚石或立方氮化硼磨料,它能精
At present, Jones & Shipman Machine Tool Works in the UK can provide an abrasive-coated tool called a micro-dumpling knife. The micro-reamer is used for ordinary honing and reaming. The requirements of the front hole finish are not rigorous. The reaming hole accuracy is 0.005mm There is no scrap. This micro reamer is composed of a spiral groove, adjustable sleeve with tapered sleeve with a matching mandrel. Reamer sleeve size can be machined according to the exact size of the hole. Due to the low reaming allowance, so after the hinge can correct the hole geometry error. Set of simple surface coated with diamond or cubic boron nitride abrasive, it can fine
