There are many types of stainless steel like 304, 303, but most of the processing manufacturers of stainless steel have the same feeling: stainless steel is difficult to process. In fact, the reasons are nothing more than the following:
1: The chemical relationship between the tool and the material to be processed causes work hardening and low thermal conductivity of the material to be processed. Not only is it easy to cause unusual wear, but it also causes chipping and abnormal cracking.
2: Low thermal conductivity causes plastic deformation of the cutting pin and faster tool wear.
3: The built-up edge is easy to cause small pieces of debris to remain on the cutting edge and cause poor processing of the surface.
4: The hardness of the machining causes the tool to wear faster and it is difficult to chip.
The solutions to the above processing problems are as follows:
A: Choosing the right tool: The tool for stainless steel should have excellent toughness, and the strength of the cutting edge and the bonding force of the coating film should be relatively high.
B: Sharp cutting edge: The chip breaker groove is wider, which reduces the cutting pressure, so that the chip removal can be well controlled.
C: Optimal cutting conditions: Inappropriate machining conditions reduce tool life.
D: Use a tool with high thermal conductivity.
