Finishing tappet hole and tappet hole wall thickness are uneven, it easy to cause hole cylindricity out-of-tolerance and size unstable the scheme adopts the six insert not equidistant points Ream machining, cutting force, the jump size jump are controlled within 0.003, it make the cutter with extremely efficiency to achieve the products precision requirement.
And can according to customer’s different machine tools select heat shrinkable type, one-piece, flange adapter and different handle interface type, etc.
When cutting tool leave the factory, the dynamic balance grade preset to G2.5 and with internal cooling hole can achieve the cutting tools’ longest service life.
