In the process of CNC metal parts processing, the machining center often leaves burrs on the parts. This kind of burr must be removed, otherwise it is easy to hurt people. However, deburring during processing has become a fixed processing cost, requiring labor, materials and time. It is necessary to reduce the appearance of burrs in metal processing. In fact, there are many ways to reduce glitches, but there are differences in cost and difficulty. The following series introduce some simple methods to reduce glitches.

Fine screening tool materials

The material of the tool is the reason why it affects the cutting performance of the tool. Especially in the high-speed cutting process of the machining center, the tool must withstand high cutting force and be heated at high temperature to cause oxidation, which will increase tool wear. Once the tool is worn, the blade will be damaged or dull, and it is easy to produce burrs. This degradation is usually difficult to eliminate. When designing the workpiece, the material of the tool must be selected according to the processing requirements and the material characteristics of the workpiece.


Calculate the angle of the tool

There are many types of tool angles, mainly front angle, back angle, front angle, back angle, etc. Properly increasing the tilt angle can effectively reduce the deformation of the incision, which helps reduce the appearance of burrs. Increasing the angle of the backrest can make the edges sharper, which reduces the extrusion of the cutting edge in the workpiece material. Advance angle and recoil angle are factors that affect the remaining area of ​​the workpiece. Properly increasing the forward angle and reducing the recoil angle can also reduce the generation of burrs in the residual area.


The mechanism by which the tool must be applied

According to the processing requirements and processing conditions of CNC parts, various structural tools can be used to control the generation of burrs. For example, it is usually possible to pour a drill bit such as a steel flange into a very small arch and feel good to touch it. Using the compound tool, remove the tool behind the front tool burr. This can effectively control the generation of burrs and improve the processing quality without consuming too much cost, which is very suitable for use in our processing plants.


In short, although burrs cannot be completely avoided during parts processing, it is necessary to find an effective deburring method that respects the environment and low cost. By focusing on the selection and use of tools, this is a good way to use light beams.
