金刚石铰刀具有加工精度高、寿命长和生产率高等优点,目前已广泛用于加工液压分配器壳体和定量泵机体等精密阀孔。金刚石铰刀的结构如图1a所示,它是由带螺旋形切口槽的铸铁套2、锥形刀杆3、前导向套5和后导向套1等组成。在套2的表面上电镀一层细小金刚石颗粒4(ACM40/28,ACM是人造金刚石微粉的牌号,40/28是粒度代号,相当于我国W40粒度,颗粒
Diamond reamer with high precision machining, long life and high productivity, has been widely used in machining hydraulic distributor housing and quantitative valve body and other precision valve hole. The structure of the diamond reamer is shown in FIG. 1a. The diamond reamer is made up of a cast iron sleeve 2 with helical notch grooves, a tapered arbor 3, a front guide sleeve 5 and a rear guide sleeve 1. The surface of the sleeve 2 is plated with a layer of fine diamond particles 4 (ACM40 / 28, ACM is a synthetic diamond powder grade, 40/28 is the particle size code, equivalent to China W40 particle size, particle size
