The invention discloses a method for
processing the gear form of a connecting rod of a
diesel engine, and a special
processing cutter. The method is to use a milling
processing method to mill the gear forms of a connecting rod body and a connecting rod cover of the
diesel engine, the milling processing method has good processing quality and high processing efficiency, the shapes of the processed gear forms of the connecting body and the connecting cover have good consistency, the contact area after
pairing and matching is large, and e contact points are even. The special cutter is a
milling cutter for milling the gear forms of the connecting body and the connecting cover of the
diesel engine, and in particular is a formed ball head taper shank cutter, wherein the molded lines formed by the rotary cuttings of
cutting edges are consistent with the molded lines of the gear form of the connecting rod, the
tool bit groove type of the formed ball head taper shank cutter is spirality of 35 degrees, the number of the
cutting edges is two, the proper alignment of the
cutting edges and the tool shank is within 0.01
millimeter, the cutter material is stable and high
wear resistant ultrafine particle hard
alloy, and the cutting edges adopt TiAlN
coating. The special cutter has the characteristics of
high wear resistance, stable performance, short manufacturing cycle, and low cost.
