Problems that are prone to occur in the process of stainless steel cutting

The first problem that easily occurs in the process of stainless steel cutting is that the strength of stainless steel is easily deformed. In the process of machining and cutting, stainless steel has a certain elongation rate, especially austenitic stainless steel, which will cause relatively large plastic deformation, which brings certain difficulties to the cutting process. Furthermore, the strength of stainless steel itself is relatively large, which increases the double resistance during the cutting process and strengthens the cutting force. Second, stainless steel cutting temperature is high. A large amount of heat will be generated during the cutting process, but the thermal conductivity of stainless steel is relatively poor, so all the heat is concentrated on the cutting area and the blade, and it is not easy to dissipate heat. Third, the cutting difficulty is great. Stainless steel is a hard material, with good plasticity and high toughness, but during processing, cutting is not easy to break and easy to stick, resulting in cutting and extruding the stainless steel surface, resulting in excessive tool wear (this is because the tool wears out, resulting in the occurrence of the blade surface. Potholes, forming small peelings and gaps; coupled with high hardness in stainless steel, direct contact with the tool during cutting, friction, scratching the tool, and work hardening, which will aggravate tool wear), so the surface processing of stainless steel deteriorates . Fourth, stainless steel is easy to expand. During the cutting process, a large amount of heat will be generated, which will cause the stainless steel to expand, making the cutting process more difficult.
