The angle boring cutter is fixed on the cutter bar by a fastening screw and locked, the angle boring cutter protrudes out of the cutter bar, and the protruding length is determined according to the allowance of a workpiece and the specification of a process file. The protruding length of the angle boring cutter can adjust the feed amount.
The angle of the angle boring cutter is ground and formed by an operator according to the specification of a process file. The R arc transition of the step hole at one end of the steel casting rotating sleeve workpiece is ensured by the grinding angle boring cutter, and the requirement of the product quality standard can be met.
The same two cutter bars are manufactured by the cutter bars, one cutter bar is used for rough machining, and the other cutter bar is used for finish machining.
The utility model provides a cast steel rotate set both ends hole or two earholes machining production efficiency low, and processing product quality is poor, especially the problem that R circular arc transition department can not reach product quality standard and customer's requirement etc. and exists. The design is simple, the operation is convenient and the maintenance is convenient; the method reduces huge special equipment purchase cost or outsourced processing cost, improves the production efficiency, reduces the production cost, and ensures that the product processing precision meets the product quality assurance requirement.
