In the process of metal processing, burrs often appear on the parts.
In the process of metal processing, burrs often appear on the parts. Therefore, in the production process, the removal of various parts of the burr, need to spend a lot of manpower and material resources. Therefore, a lot of cost is wasted. So, how to effectively reduce the production of burrs in metal processing? Here we come from the tool to introduce.
1, choose the right tool material
The performance of the tool material itself is the main factor affecting the cutting performance of the tool, and the tool in the cutting process, the working environment is very bad, the tool has to bear a lot of cutting force, but also by high temperature heating and oxidation, which will lead to increased tool wear. When the tool wear, the cutting edge will become dull, at this time it is easy to produce coarse burr, this burr is very difficult to remove. Therefore, when designing the tool, the tool material must be selected according to the processing requirements and the performance of the workpiece material.
2. Choose a reasonable tool angle
The tool angles that affect the generation of burrs are mainly rake angle, back angle, main deflection angle, auxiliary deflection angle, etc. If the rake angle is properly increased, the deformation of the cutting can be effectively reduced, which is helpful to reduce the burr generation. And the appropriate increase in the rear angle, can make the cutting edge sharp, reduce the extrusion of the cutting edge on the workpiece material, to reduce the generation of burrs also have some help. The main deflection angle and secondary deflection angle mainly affect the main factors of the residual area, and burrs are often generated on the residual area during cutting. In order to reduce the generation of burrs, it is necessary to increase the main deflection angle and reduce the secondary deflection angle.
3, the use of appropriate tool structure
According to the processing requirements and processing conditions of parts, various structural forms of tools can be used to control the generation of burrs. For example, the use of composite tools, in the processing process, the burr generated by the cutting of the previous tool can be removed by the latter tool, which effectively controls the generation of burrs and improves the quality of processing.
In production, the processing principle, characteristics and application occasions of each deburring method are different. For different types of burrs produced by various parts and processing methods, what kind of deburring method is very important. There are many factors that affect deburring, but it is mainly part processing conditions and processing requirements. Therefore, in choosing the method of deburring, the following issues need to be considered:
1. The production batch, material characteristics, structure shape, size and other factors of the processed parts.
2. The processing capacity, economy, existing deburring equipment and technical level of deburring method.
3, the side effects of deburring.
