Laser engraving product parts deburring, descaling and mirror polishing process method

How to deburr, descale and mirror-polish parts of laser engraving products?

Laser engraving is an exquisite application of modern precision machining and manufacturing industry. Based on CNC technology, laser beam is used to irradiate the surface of the workpiece, and the material is evaporated, gasified or ablated through instant high temperature to obtain specific patterns. In the industries of advertising decoration, printing and packaging, leather shoes and clothing, model making, craft gifts, etc., laser engraving, a precision machining technology, has been widely used. Today we will share a case of how to remove turning tool pattern, stains, oxide scale and burrs from the camera lens cover of aluminum alloy to achieve mirror polishing. This finishing process solution is also suitable for the deburring, descaling and polishing needs of other precision machining product parts such as laser, plasma, and flame cutting.

5. Additional instructions
  • The laser engraving beam has strong energy, so it will generate very high temperature during engraving, which can easily form a hard and wear-resistant oxide layer on the surface of product parts. In addition, the precision of laser engraving is very high, and the strokes and lines in the pattern are very fine, so it is difficult for abrasive media to penetrate into these parts for finishing. Now we use a vibrating finishing machine, which has strong finishing force and high cutting efficiency, and the working bowl uses an anti-collision divider structure, thus avoiding the problem of collision and damage between workpieces. Abrasive media uses a heavy-cutting angle cut tri-angle ceramic tumbling media, which can achieve the effect of rapid deburring and descaling.
  • Fine finishing uses light cutting force tetrahedron-shaped plastic media, also called polyester media. This tumbling media has small grit size and light weight, will not cause deformation of the workpiece, and can further reduce the surface roughness.
  • The last step after fine finishing is to use a mirror vibratory bowl polishing machine with precision finishing media to enhance the brightness and mirror polishing.

6. Final summary
  • In this case study, we demonstrated the process of automatically removing the burr, oxide scale, turning tool lines from the surface of a laser-engraved aluminum alloy camera component to achieve mirror polishing effect.

Deburring, deflashing and polishing technology of laptop middle frame, bezel, chassis of magnesium-aluminum-zinc alloy die-casting parts

How to deburr, deflash, descale, polish magnesium alloy laptop frames of digital product parts?

Among the parts of digital products such as mobile phones, laptops, digital cameras, and tablet computers, the middle frame, bezel, chassis, shell are mostly made of soft metal materials such as aluminum alloy, magnesium alloy, and zinc alloy through die-casting and then CNC precision machining. These metal structural parts often produce burrs, turning lines, and stains during the production process. Therefore, the automated precision finishing and polishing process of the product surface is particularly important. In this case, we will share a magnesium alloy laptop component – the middle frame structure of the automatic high-efficiency deburring, descaling, polishing and brightening process technology and method. This finishing and polishing process solution is also suitable for the deburring, flash removal, burnishing of other soft metal machined parts such as aluminum alloy, zinc alloy, and copper alloy.

5. Additional instructions
  • Aluminum-magnesium alloy frame, bezel, chassis is an important part of electronic digital products. Due to its light and soft material, and the complex and special-shaped parts such as holes, gaps, and corners on the surface, the dimensional accuracy is high. Therefore, the cutting force for removing burrs, flash and oxide scale should not be too heavy, and the complicated body of parts should be fully polished. Therefore, the polishing machine adopts rectangular tub finisher, and small-sized tetrahedron-shaped plastic media is used for rough finishing, mixed with large-sized cone-shaped polyester media, the sharp angle of the plastic media can reach deep into the grooves and corners to remove burrs and oxide layers.
    Fine polishing uses precision ceramic polishing media without cutting force, spherical porcelain polishing media, which has a high density and has a polishing and brightening effect, which can further reduce the surface roughness.
  • In order to improve the anti-rust performance of the product after water treatment, use a vibratory drying machine with corn cob polishing media to absorb moisture and dry the inner and outer surfaces.
