Problems solved by technology

[0002] At present, manufacturers generally use the following three methods when processing large tapered holes: one is to use a large tapered reamer to ream the tapered hole. This method takes a long time to process the tapered hole, and the production efficiency is low. It will affect the processing accuracy of the tapered hole, and the reamer is disposable, and the price is relatively expensive; the second is to use the flat rotary disc boring method, which is limited by the expensive price of the flat rotary disc; the third is to use the arc cutter The processing method of helical differential compensation and line approximation, because the surface of the taper hole processed by this processing method is formed by line approximation, the milling cutter interpolates one circle per arc, making it difficult to guarantee the hole accuracy and surface roughness. The processing time of taper hole is long and the production cost is high. The circular arc knife is used to process the large diameter Φ105.86, the small diameter Φ95, the depth 536.4, the surface roughness Ra6.3, and the taper 1 / 50 taper holes, processing each hole takes about 16 hours
