The quality of surface roughness of line cutting is one of the important indicators of machining accuracy and it directly affects the quality and service life of the product.It is necessary to take measures to improve the surface roughness of line cutting to ensure product quality and extend service life.
Improvement measures of line cutting surface roughness
1. Selection of cutting tools
The selection of line cutting tools directly affects the surface quality of line cutting parts. According to different cutting materials, cutting process and machining accuracy, rational selection should be made to ensure the line cutting tool has good quality and sharpness.
2. Optimization of cutting speed
During line cutting machining, it is also necessary to set a suitable cutting speed. The cutting speed should not be too fast nor too slow. If the cutting speed is too fast, the quality of line cutting surface will be affected. If the cutting speed is too slow, it will also increase the frictional resistance between cutting tools and workpieces, resulting in lower cutting efficiency.
3. Control of cutting parameters
Reasonable cutting parameters are very important for the processing of line cutting. The cutting parameters such as cutting depth, cutting speed and feed rate should be properly controlled to make sure that the cutting parameters can make full use of the cutting tools and ensure the surface roughness.
4.Correct installation of cutting tools
In the process of line cutting machining, it is necessary to ensure that the cutting tools are installed correctly to avoid deformation of cutting tools and reduce the cutting force. Unreasonable installation will result in poor workpiece surface finish, increase power consumption and reduce service life of cutting tools.
5. Selection of materials
It is necessary to choose the appropriate material for the line cutting machining. Different material properties determine different machining parameters.The higher strength and hardness of the cutting material, the smaller the cutting speed will be, and the greater the cutting force will be, resulting in higher surface roughness.
6.Cooling system
In the process of line cutting machining, it is necessary to ensure that there is a suitable cooling system. The temperature of cutting tools should be very low in order not to damage the precision of the machined parts. The coolant can reduce the cutting force, reduce tool wear and improve the surface quality.
7.Grinding and grinding
In the case of high-precision line cutting processing, grinding and grinding work must be carried out. The grinding method can be used to adjust the machining surface to a certain degree of accuracy, which can improve the precision and surface roughness of the line cutting machining.
Conclusion
The above is about the improvement measures of line cutting surface roughness.Hope it can help you. In line cutting machining, it is necessary to pay attention to the above matters to ensure the machining accuracy and high quality of line cutting parts.
In addition, regular inspection of the tools and maintenance of cutting machine is also necessary in order to ensure the consistency of machining accuracy.
