During the processing of stainless steel strips, there may be difficulties such as high processing strength, laborious cutting, and easy wear. If these problems cannot be effectively solved, the processed stainless steel strips will have rough surfaces and high wear strength, which is not conducive to secondary processing situation. Then Chengdu Stainless Steel Processing will explain to us how to solve the difficulties in the processing of stainless steel strip?
All stainless steel processing manufacturers have the same feeling: stainless steel is difficult to process. In fact, the reasons are as follows:
1. High cutting force: If the cutting force is large, the strength of the stainless steel strips of different raw materials is inconsistent, so the corresponding force when cutting is relatively large, and it is not easy to be plastic. When selecting technologies such as drilling and boring, try to choose a technology that has greater strength than the processing raw material, so that it is not easy to deform the stainless steel belt, and it can also reduce the cutting strength during cutting.
2. High cutting temperature: From the perspective of thermal conductivity, the stainless steel strip material is not conducive to thermal conduction. During the cutting process, the processing technology and the workpiece want to touch, resulting in high processing temperature, which also adds tool wear. It can be solved by the thermal solution of "Solution Solution, Water Toughness Solution". Without changing the physical data and initial data, the metallographic structure of the processed data must be fine-tuned to improve the temperature during processing .
3. Simple sticking knife during cutting: When processing several raw materials of stainless steel belt, there will be a certain viscosity between the processing technology and the workpiece due to the strength of the cutting. , The appearance is easy to wear, and the danger of the sticky knife to the tool is also very large. Solving such questions can be avoided through the following methods,
1) Replace sharp tools.
2) Decrease the spindle speed.
3) Increase the feed speed.
4) Improve the cooling method.
5) Replace sharp tools.
6) If the spindle speed can be adjusted, increase the spindle speed.
7) Reduce the feed rate.
4. The machining hardness causes the tool to wear quickly and it is difficult to discharge chips.
5. Low thermal conductivity causes plastic deformation of the cutting edge and faster tool wear.
6. Detritus tumors simply form emblems, small pieces of powder remain on the cutting edge, and lead to poor machining appearance.
