The burrs generated during the processing and manufacturing of precision hardware parts will have an adverse effect on the processing accuracy

The burrs generated during the processing and manufacturing of precision hardware parts will have an adverse effect on the processing accuracy, assembly accuracy requirements, reprocessing positioning, operation safety and appearance quality of the parts. Therefore, the requirements for deburring technology of precision hardware parts are getting higher and higher, which has made deburring technology receive widespread attention and rapid development. From simple manual operation to mechanization, automation and intelligence.

In the processing of precision hardware parts, the generation of burrs is often inevitable. In the study of deburring, we must first start with the design. Study and design the structure of parts with few burrs or no burrs. Secondly, explore advanced deburring technology for different types of burrs. There are positive burrs and negative burrs, and there are burrs when cutting plastic materials and castings, injection molding, stamping and other processing. The formation of positive burrs has the characteristics of convex forming surface. The height and size of burrs are related to the processing parameters. When cutting hard and brittle materials, the edges of parts often produce defects such as chips, forming the so-called negative burrs. Negative burrs may form small crack defects. It may even cause product scrapping.

In the process of part design and process planning, attention should be paid to preventing and reducing burrs in part processing. Mechanical deburring is the earliest and most widely used method. There are mainly vibration deburring, jet deburring, roller grinding deburring, eddy current grinder deburring, etc. These deburring methods and equipment are widely used. In addition, special mechanical equipment such as belt grinding equipment is also used to remove burrs.

In order to improve the research level and application effect of deburring technology for precision hardware parts, the following suggestions are put forward:

1) Strengthen technical transformation research, promote burr-free processing technology and new deburring technology, improve existing testing equipment as soon as possible, put it into actual production, and strengthen the promotion and application of mature technology.

2) On the basis of summarizing production practice experience and experimental research data, deepen theoretical research, explore new deburring processes and new processes, and study multi-method composite processing technology.

3) Use digital technology to design and manufacture automated and intelligent deburring equipment to improve the overall level of the machinery manufacturing industry.
