Since the 21st century, due to the improvement of living standards, more than 30% of Chinese residents need high-grade water pipes to meet their needs of high-quality life. Therefore, high-quality stainless steel materials move from high-grade tableware to household water pipes. It has become a trend to select high-quality thin-walled stainless steel pipe in tooling or home decoration engineering. Thin wall stainless steel water pipe and stainless steel pipe fittings will become an indispensable part of the building materials market in the future.
Stainless steel is a recognized health material that can be implanted into human body. It has been many years since stainless steel was used to make water pipes in developed countries. With the characteristics of safety and reliability, sanitation and environmental protection, economy and applicability, thin-walled stainless steel pipe has gradually become a new choice of water supply pipe, and has become the current world trend and development direction. Stainless steel water pipe is called the real green pipe in the 21st century.
What are the difficulties in the processing of stainless steel pipe fittings?
The use of stainless steel profiles is becoming more and more common, and the demand for stainless steel profiles is also increasing, which promotes the development of stainless steel precision machining to a certain extent. Here are the difficulties in processing stainless steel pipe fittings:
1. The work hardening of stainless steel pipe fittings is serious: when cutting, the work hardening tendency is large, and the tool cuts in the work hardening area, which shortens the tool life.
2. Large cutting force and high cutting temperature: this type of material has high strength, large tangential stress and plastic deformation during cutting, so the cutting force is large. In addition, the thermal conductivity of the material is very poor, and the high temperature is often concentrated in the narrow and long area near the cutting edge of the tool, which speeds up the wear of the tool.
3. Stainless steel pipe fittings are easy to stick the knife: no matter any stainless steel, it has the characteristics of strong and tough chips and high cutting temperature. When the strong chips flow through the rake face, the tool wear will be accelerated.
4. The tool wear is accelerated, the material generally contains high melting point elements, large plasticity and high cutting temperature, which speeds up the tool wear and frequently grinds and changes tools, thus affecting the production efficiency and improving the tool use cost.
