Problems solved by technology

[0004] Due to the special processing mechanism of traditional vibration cutting, although it can reduce the cutting force, reduce the cutting temperature, improve the ultimate cutting ability and processing quality, but due to the limitation of the limit speed, the cutting line speed is very small (generally 4 ~ 6m / min), Especially for rotating parts such as large-diameter long shafts or deep holes made of difficult-to-machine materials, the efficiency is very low, which is greatly restricted in actual cutting applications
