3d-With the continuous progress of science and technology and the increasing development of industrial manufacturing technology, precision metal parts are more and more widely used in various fields. In order to meet the strict requirements of its use, the machining accuracy and surface quality of the parts must be fully guaranteed. Among them, deburring as the last process of metal parts processing, to improve the service life of the parts, reliability and safety is of great significance. This paper will focus on precision metal parts deburring technology and application to discuss.
First, the necessity of deburring precision metal parts
In the processing of metal parts, due to the limitations of cutting, forging, welding and other processes, the surface of the parts will often produce burrs, scratches, oxidized skin and other defects. These defects not only affect the appearance of the quality of the parts, but also reduce the performance of the parts, and even have a serious impact on their service life. Therefore, in order to ensure the quality and performance of metal parts, it must be deburred.
Second, precision metal parts deburring technology
At present, precision metal parts deburring technology mainly includes the following types:
- manual deburring: through manual operation to remove burrs on the surface of the parts, applicable to small quantities, simple parts. This method is less efficient, the quality is not stable, and it is difficult to meet the needs of mass production.
- mechanical deburring: the use of special deburring machine tools for deburring parts. This method can remove deeper burrs, but the surface finish requirements of the parts is not ideal.
- chemical deburring: chemical corrosion, electrolysis and other methods to remove burrs on the surface of the parts. This method requires a higher surface finish of the parts, but the choice of materials is limited, not for all metal parts.
- Electrolysis deburring: through the electrolytic solution on the parts of the electrolytic treatment, so that the burr partially dissolved, to achieve the purpose of deburring. This method is applicable to a variety of metal materials, deburring effect is better, but the cost of equipment is higher.
- magnetic polishing deburring: the use of magnetic field distribution produces a strong and smooth magnetic effect, so that the stainless steel needle, grinding needle, grinding material and workpiece for high-frequency rotary movement, so as to achieve deburring, polishing, washing and other multiple effects. This method is highly efficient, effective and can meet the needs of mass production.
Third, precision metal parts deburring application cases
In the aerospace, medical equipment, automobile manufacturing, precision instruments and other high-precision manufacturing areas, metal parts deburring technology plays an important role. For example, in the aerospace field, due to the extremely high precision requirements of the parts, the traditional deburring method is difficult to meet its quality requirements. And magnetic polishing deburring technology can guarantee the accuracy of the parts at the same time, improve deburring efficiency, to meet the needs of mass production.
In short, precision metal parts deburring technology is important in improving the quality and performance of parts. With the progress of science and technology and the development of industrial manufacturing technology, deburring technology will continue to innovate and bring more possibilities for the processing of metal parts.
