Improve the quality and efficiency of taper machining
Cone pin coupling is widely used in mechanical design. In order to ensure the accuracy of its positioning, smooth and safe transmission, the precision of the taper hole and the taper pin is very high. The surface roughness is generally R_a3.2, which gives Processing brings certain difficulties, especially the addition of tapered holes in steel. First, the improvement of the process of the reaming hole hole According to the conventional method of adding the cone hole, firstly, the grading of the twist drills of different diameters is used or the step drill is used to drill the step, and then the coarse and fine reamers are used for the coarse and fine reaming. 1). This method is complicated to process, and the remaining amount of the bottom hole is difficult to grasp, and it is easy to have a small amount of hinges and a large amount of reaming.
