Stainless steel pipe processing and hardening

Stainless steel pipe work hardening is severe: the work hardening tendency is large during cutting, and the tool is cut in the work hardening zone to shorten the tool life.

1, the use of stainless steel profiles is becoming more and more common, and the demand for stainless steel profiles is also increasing, which has promoted the development of precision machining of stainless steel to a certain extent. Here are some of the difficulties in the processing of stainless steel pipe fittings:

2. Large cutting force and high cutting temperature: This type of material has high strength, large tangential stress during cutting and large plastic deformation, so the cutting force is large. In addition, the thermal conductivity of the material is extremely poor, and the high temperature tends to concentrate in the narrow area near the cutting edge of the tool, thus accelerating the wear of the tool.

3, stainless steel pipe processing easy to stick knife: no matter any stainless steel, there are characteristics of strong chipping and high cutting temperature during processing. When the strong chips flow through the rake face, the tool wear is accelerated.

4, the tool wear is accelerated, the material generally contains high melting point elements, plasticity, high cutting temperature, which makes the tool wear faster, sharpening the knife and changing the tool frequently, which affects the production efficiency and improves the tool use cost.
