Abstract of the main content of the paper: pressureless sintering as a new diamond tool making technology in recent years.å·³ Beginning to be promoted and recognized in the industry, the maximum edge value of diamond can reach 2/3 of the particle size, and the tool life is close to that of the ordinary sintering method. When the diamond saw blade is produced by pressureless sintering technology, the shape retention of the saw blade is difficult to control. It is one of the factors that restrict the development of this technology. In the case of cold forming, in order to increase the density of the carcass, in the actual production, the method of increasing the pressure is often used, but when the limit pressure is exceeded, the pressure will decrease the density of the carcass. In response to this problem, this paper discusses the forming process using cold isostatic pressing after pre-compression, and studies its effect on the shape and performance of the pressureless sintered diamond saw blade. The powder cold isostatic pressing forming method has the following advantages: the powder is pressed in all directions in the soft mold, and the pressing time is controllable, which can eliminate the adverse effect of the pressure gradient on the compact density when the steel mold is pressed, and the blank strength is higher than the same condition. The strength of the mechanical compact. After the pre-compression, the cold isostatic pressing process is adopted, and the density of the saw blade is uniform. When the pressureless sintering is performed, the shrinkage of the diamond saw blade in all directions is uniform, and the shape retaining property of the saw blade is improved. The above text is selected from the "Impact of Cold Isostatic Pressure Process on the Performance of Pressureless Sintered Diamond Saw Blades", which is included in the "2012 China Superhard Materials Technology Development Forum Proceedings".Here you can find the related products in Water Analysis Measurement, we are professional manufacturer of Water Analysis Measurement,PH Meter For Water Testing,Conductivity Meter For Water Testing,Tds Analyzer.
