To overcome the characteristics of cutting stainless steel materials in stainless steel machining The stainless steel materials that are often cut are mostly SUS303, SUS304 and SUS316 of the Waseda iron series. However, due to their high corrosion resistance and strength and toughness, these materials will not be easy to dissipate heat during cutting. The problems of work hardening and chip sticking on the tool make their machinability difficult. In order to overcome the characteristics of cutting stainless steel materials, the material, coating, and tool design of the cutting tool are key priorities. The stainless steel cutting series products mainly focus on stainless steel cutting, with the following explanations: 1、 For stainless steel cutting, in addition to easy chip breaking and good chip removal, how to take away processing heat energy and reduce work hardening phenomenon. 2、 Stainless steel cutting mostly adopts wet cooling, and the more suitable coating is' G10 '. 3、 High helix angle R groove and seismic design; When machining with high efficiency, the cutting speed Vc value can reach 100-120m/min, and it also has a processing capacity of 1D in groove milling and side milling.
