Stainless steel plate in the cutting processing of the most easily encountered problems

Friends who understand the stainless steel industry may know that the most difficult thing to deal with in the processing of stainless steel plates is the cutting position. During the cutting process, stainless steel will show some characteristic phenomena.

1. Stainless steel will generate a lot of heat during the cutting process. Because the thermal conductivity of stainless steel is relatively poor, all the heat is concentrated in the cutting area and the blade, which is difficult to heat.

2. Stainless steel sheet in the processing and cutting process, due to its certain elongation, will have a large plastic deformation.

3. Due to the relatively high hardness of stainless steel, it is not easy to break and adhere during processing, resulting in cutting and extrusion of the stainless steel surface, resulting in excessive wear of the tool (this is because of tool wear, resulting in pits and small spalling on the blade surface. And the notch, coupled with the high hardness of stainless steel, the direct contact with the tool during the cutting process, friction, scratches on the tool and work hardening will aggravate the tool wear), thus worsening the surface processing of the stainless steel plate.

4. Due to the principle of thermal expansion and cold contraction, stainless steel will expand due to friction in the process of cutting stainless steel.
