在中、高强度的磁场中磁处理,是提高切削刀具耐磨性的有前途方法之一,它能消除与工具制造和热处理相关联的缺点,促使刀具材料组织中的相转变,改变等温转变速度,这对于高温条件下的切削过程是重要的。为确定磁处理后切削刀具的强化性能,进行了实验室和工业性试验。用P9K5,P6M3,P6M5钢制造的φ6～18mm钻头,加工合金钢和结构钢:30X、1X13、1X15、20、30、45、40X等一直到完全变钝。后面磨损0.6mm定为变钝极限。设计了钻头磁场强化用的—7型专用设备。它的外壳是角型材并装的。电磁铁、整流器、变压器、自动开关
Magnetic processing in medium and high strength magnetic fields is one of the promising ways to increase the wear resistance of cutting tools by eliminating the disadvantages associated with tool manufacturing and heat treatment, enabling phase transitions in the tool material organization, changing isothermal transformations Speed, which is important for the cutting process at high temperatures. To determine the enhanced performance of magnetic cutting tools, laboratory and industrial tests were conducted. With P9K5, P6M3, P6M5 steel manufactured φ6 ~ 18mm drill, alloy steel and structural steel processing: 30X, 1X13, 1X15, 20,30,45,40X, etc., until completely dull. Behind the wear 0.6mm set blunt limit. Designed with a drill-magnetic field-7-type special equipment. Its shell is angular profile and installed. Electromagnet, rectifier, transformer, automatic switch
