Description
One, technical field
The present invention relates at a kind of composite material for saw blade.
Two, background technology
The applicating history of diamond saw blade is quite long, and first diamond saw blade made by the Frenchman in the world, and owing to the gradually maturation of powder metallurgy process, people began to adopt metal powder metallurgy manufactured saw blade afterwards.The research of China's diamond saw cutting tool begins later, just succeeds in developing the welding saw blade beginning of the seventies, is mainly used in insulating materials, electroceramics cutting at first.The eighties as the high-efficient cutting instrument, diamond cutting tool has obtained rapidly development.Recent two decades comes, do having arrived widely of diamond saw blade of cutting edge uses with the diamond cutter head, industries such as building, traffic, chemical industry, timber processing, non-ferrous metal cutting use the ratio of diamond saw blade increasing, especially diamond saw blade has become the principal element that determines project progress and cost in lithotome processing, highway construction and concrete works, along with the range of application of diamond disc is extensive day by day, processing object is complicated day by day, and these have all proposed new challenge to the design of diamond disc with manufacturing.
Carbonado about 50% is used to make the processing of stone instrument in the world at present, wherein mainly is the stone material saw blade.The condition of work of diamond saw blade is more abominable, at a high speed, vibration, high temperature proposed harsh requirement to the performance of diamond saw blade, and be along with improving constantly of the saw blade cutting speed and the depth of cut, also more and more higher to the requirement of diamond saw blade intensity.
Three, summary of the invention
