The processing of precision stainless steel parts is facing great difficulties,which is due to the characteristics of stainless steel materials,such as high hardness,easy to crack,large cutting force and easy to scratch.To solve these problems,the following measures can be taken:
Precision stainless steel parts processing
First,choose the right cutting tool
Blade with high hardness and strong wear resistance:When processing precision stainless steel parts,it is necessary to select cutting tools specially suitable for stainless steel materials.The blade of this kind of tool has high hardness and strong wear resistance,which can effectively improve the processing efficiency and quality.
Suitable cutting tool material:cubic boron nitride blade is recommended.Its rigidity is second only to diamond,and it can withstand extremely high temperature.It is chemically inert and will not react with iron group metals at high temperature.It is especially suitable for the processing of stainless steel precision parts.
2.Reduce the processing temperature
Adopt low temperature cooling method:In view of the characteristics of stainless steel easy to hot cracking,it can be solved by reducing the processing temperature.In the process of precision machining,liquid nitrogen and other cryogenic cooling methods should be used to control the machining temperature in an appropriate range,so as to reduce workpiece deformation and tool wear.
3.Reasonable design of cutting tools and processing parameters
Optimize the design of tool structure:In order to reduce the cutting force and extend the service life of cutting tools,reasonable tool structure design can be adopted,such as reducing the rake angle and relief angle of the tool,increasing the cutting edge angle,etc.
Select the appropriate processing parameters:according to the specific material properties,workpiece shape,cutting tools and other factors,reasonably select the processing parameters,such as cutting speed,feed rate,etc.,to ensure the processing quality and process stability.
IV.Treatment before processing
Heat treatment or chemical treatment:Before precision machining of stainless steel parts,heat treatment,chemical treatment and other methods can be used to improve the performance of the material itself and machining performance.These treatments help to reduce the hardness and toughness of the material and make the process smoother.
5.Use proper cutting oil
Cutting oil with good adhesion resistance and heat dissipation:As stainless steel has the characteristics of easy adhesion and poor heat dissipation,it is very important to select cutting oil with good adhesion resistance and heat dissipation in the cutting process.This kind of cutting oil can effectively reduce the cutting temperature,reduce the cutting force,and improve the cutting life and processing efficiency of the tool.
6.Adoption of high-precision machine tools and advanced technology
High precision machine tools:The precision machining of stainless steel parts largely depends on high precision machine tools and advanced processing technology.High-precision machine tools can ensure the stability and accuracy of the machining process,thereby improving the dimensional accuracy and surface quality of the parts.
Advanced processing technology:such as laser processing,ultrasonic processing and other advanced technologies can further improve the processing accuracy and efficiency.These technologies can realize the fine processing of stainless steel materials and meet the processing needs of high-precision parts.
VII.Continuous improvement and optimization
Quality inspection and feedback:The dimensional accuracy and surface quality of the finished precision stainless steel parts shall be strictly inspected to ensure that they meet the requirements of the drawings.The unqualified products shall be repaired or scrapped,and the experience and lessons shall be summarized to optimize the processing technology and parameters.
Technological innovation and upgrading:With the continuous progress of science and technology and the change of market demand,we need to constantly learn and master new technologies,new processes and new materials to adapt to market changes and meet customer needs.At the same time,we should pay attention to environmental protection and sustainable development,and promote the development of precision stainless steel parts processing towards green and intelligent direction.
