近几年来的试验证明,砂轮的速度从25～35米/秒增大到50～80米/秒和采用强力磨削的方法可以提高加工效率和延长砂轮的寿命,并可提高工件的精度和加工表面的质量。因此全苏工具科学研究院在莫斯科工具厂对砂轮切割工具毛坯、无心磨削带锥柄的钻头和磨削丝锥螺纹进行了高速磨削工艺试验。砂轮切割的试验是在改装的Mφ332型切割机床上进行的。试验采用了高速切割镶片砂轮ΠΠ400×4×32,规格为14A63HT1Бу和14A50HT1Б,由乌拉尔磨料与磨削科学研究所研制和伊尔沙夫砂轮厂生产。工具毛坯,直
Experiments in recent years prove that the speed of the grinding wheel is increased from 25 to 35 m / s to 50 to 80 m / s and the method of intensive grinding can improve the processing efficiency and prolong the service life of the grinding wheel and improve the accuracy of the work piece The quality of the machined surface. Therefore, all the Soviet Union Tool Science Research Institute in Moscow tool shop on the cutting tool blanks, centerless grinding with taper shank bit and tap thread grinding process of high-speed grinding test. Wheel cutting test is carried out on the modified Mφ332 cutting machine. The test used high-speed cutting inserts ΠΠ400 × 4 × 32, the specifications for the 14A63HT1Бу and 14A50HT1Б, developed by the Ural Institute of Abrasive and Grinding Science and Irsar Abrams factory production.
