The Study Of Design And Application Of Cutter Of Spinning Cutting Machine

In the past century, on account of the all-round progress of numerical control machine, numerical control system, cutter material and coating technology, mental cutting technics got an extremely rapid development. At the end of the 20th century, mental cutting technics stepped into the high speed cutting phase, whose main technology characterized by 500 to 1,000 percent speed improvement. At the same time, high speed cutting technology made a strong claim to manufacturing for higher level in the following aspects: high rigidity and precision of machine and clamp system cutter's material performance and process precision, and cooling effect.With the development of mental cutting technics, it is necessary for us to make use of high performance cutter materials in place of low performance cutter materials, moreover, it has been a trend in application field, for example, fine particle cemented carbide replacing high speed steel and ceremic or cermet replacing cemented carbide. The usage scope of superhard material PCD and CBN has got further expansion.The application of changing cutter's performance by the way of coating technology got widespread day by day. Due to all-round development of various cutter materials and cutting technics, the efficiency and all-round cutting level of mental cutting in different fields and different procedure have made remarkable progress. What's more, the development, opening up the new phase of mental cutting, has laid the development foundation of manufacturing and manufacturing technology. By using the most advanced technics, this subject developed alloy tool steel(Cr12MoV) cutter to cut compressor manufactured by Danfoss, which conforms to the developing tendency of cutter's materials and technics.The study on this subject is as following:Chapter 1: Illustrate the present situation of spinning cutting machine and cutter and put forwards the research content and meaning of this subject based on the problems arising during Danfoss's usage.Chapter 2:Determine to-be-used material through making comparions of all kinds of alloy materials used to make spinning cutting machine.Chapter 3:Study principle of cutter design and compare various shapes of cutter to fix on the cutter shape, make integrated structural design of cutter as well. Chapter 4:Compare key machining processing technology and procedure, espcially make complete probe and study on forging technics to be certain of cutter processing technics.Chapter 5:Check up the rigidity and metallurgical structure of manufactured cutter and analyze performance data obtained from continuous cutting tests.Spinning cutting machine, manufactured with the developed technics, reaches the aim(cut over seventy compressors) fixed by the subject.
