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.
  • If you need professional technical support for laser, plasma, wire cutting and other precision hardware parts or the following products in terms of deburring, deburring, removal of turning tool marks, mirror polishing, you can refer to the above cases:

Deburring, descaling, chamfering and polishing process of CV joint for automobile parts

The CV joint is an important component of the ball cage universal joint, a steering component of the car. On its drum-shaped side wall, six window holes are milled by CNC to install the steel balls responsible for rotation. If there are burrs on the inner wall of the window hole, then over time, the car will make a “clicking” noise during driving or turning. Therefore, the last process in the product production process is deburring and finishing. The commonly used polishing process is to use the vibrating deburring process to put the CV joint into the working bowl of the vibratory finisher for batch deburring. One disadvantage of this process is that the burrs on the edge of the window hole will have a flanging and curling phenomenon, which cannot be removed cleanly; at the same time, collisions between products will cause bumps and wounds. Today we will share how to improve and optimize the process of a 20 chromium manganese titanium CV joint product to solve the problem of unclean burr removal and bumps on the surface of the workpiece. This finishing process method is also suitable for other deburring, deflashing processes such as vibratory, centrifugal barrel, disc finishing where the burrs are not removed cleanly, and the collision between workpieces causes bumps and needs to improve and adjust the finishing and polishing process.

Deburring, descaling and mirror polishing technology method for deep drawing stamping parts of stainless steel

How to remove burrs, oxide scale, stretch lines and mirror polish the stainless steel deep drawing stamping parts?

Metal drawing stamping process is a common metal forming process. The difference between it and the standard stamping process is that standard stamping does not significantly change the depth of the formed product, while drawing (stretching) stamping generally significantly increases the depth of the formed product. Most of the daily necessities we use are made of metal by deep drawing and stamping processes. Today we will share a case of reducing surface roughness and mirror polishing of parts made of 304 stainless steel plates after deep drawing and stamping. This polishing process solution is also suitable for deburring, descaling, removing stretch marks, wrinkles, and mirror polishing of hardware drawing and stamping parts made of other materials such as aluminum alloy, carbon steel, copper, or nickel-titanium alloy.

5. Additional instructions
  • There is a shallow oxide layer on the surface of the pinion needle valve, and the burrs on the edge of the cutting surface at the bottom of the cylinder are also relatively slight. The process requires that the dimensional accuracy of the product should not be affected after polishing. Therefore, the time for deburring and removing oxide scales should not be too long. so the polishing machine uses a centrifugal barrel finisher. Small-sized angle cut cylinder ceramic tumbling media are used for coarse finishing. The sharp angle of the ceramic deburring media can reach into the grooves and corners to remove burrs and oxide layers.
    Fine polishing uses precision polishing media without cutting force straight cut cylinder high-density porcelain polishing media, which has a high density and has a polishing and brightening effect, can further reduce the surface roughness.
  • In order to improve the anti-rust performance of the product after water treatment, after fine polishing, use a centrifugal spin dryer to dehydrate and dry the moisture on the inner and outer product surfaces.

  • Because stainless steel metal sheet processing parts are easily deformed, a centrifugal finishing machine with a small-capacity working barrel is used to reduce the operating speed and use it with softer texture cone-shaped resin media (also called plastic media) is used to chamfer and deburr. If you use ceramic tumbling media or other very hard abrasive media will cause problems such as deformation and bending of the workpiece, and ceramic deburring media can easily contaminate the stainless steel surface and make the surface black.
  • So why don’t polish parts use vibratory polishers? Because the vibrating polishing machine will cause the thin parts to stick to each other, and multiple pieces will fit together, which will not achieve the finishing and polishing effect.
  • Products can be separated automatically using a vibrating separator, to control the vibration amplitude of the vibrating separator so that no bending deformation occurs due to mutual collision.
  • In order to improve the anti-rust and anti-corrosion performance of the product after water cleaning, vibrating dryer, with corn cob polishing media, dry the moisture and wipe away water stains on the surface of the product.

5. Additional instructions
  • Because stainless steel is harder material, ceramic deburring ball is used for rough finishing to remove scale and burrs. If you use angle cut triangle ceramic deburring media or angle cut cylinder ceramic deburring media with sharp corners or edges will cause scratches, pitting and other problems on the surface of the product.
  • The workpiece material is hard and has no edges and corners, so it can be automatically separated by a machine. There will be no surface damage caused by collision with each other, which greatly improves the efficiency of discharging materials.
  • For stainless steel product parts, polish with stainless steel polishing ball is very effective in brightening. The surface of the product after rough finishing has no luster, but it will become bright after vibratory fine finishing and polishing with stainless steel media.
    In order to further improve the smoothness and brightness of the product surface, finally use tumbling barrel polishing machine, combined with walnut shell polishing media, achieves a quasi-mirror polishing effect with the support of polishing paste.

5. Additional instructions
  • Because the workpiece material is relatively soft, resin media can only be used to roughly remove scale and burrs. If you use ceramic deburring media, so the hardness is too high and the sand grits are too coarse, it will wear the surface of the product and cause scratches, pitting, color contamination and other problems.
  • Also because of the material, if a machine is used for automatic separating, the collision of workpieces will cause surface damage.
  • Zinc alloys can easily re-oxidize when exposed to water and air. Therefore, we need to dry the water immediately after polishing.

6. Final summary
  • In this case, we demonstrate a process of using a resin (plastic) finishing media to deburr, remove scale and brighten on the surface of a zinc alloy handle.
  • This process is also suitable for polishing belt buckles, jewelry pendants, souvenirs, craft gifts and other products produced from aluminum alloy and copper die-casting parts.

5. Additional information
  • Because the rubber material is soft, elastic and tough, heavy cutting force spherical ceramic deburring media is used to roughly finish the parting line. If you use ceramic media with sharp angles, such as triangular brown corundum deburring media, they may scratch the rubber surface, causing scratches, pitting and other problems on the product surface.
  • To achieve brightness on the rubber surface after rough finishing, it is necessary to use ceramic media with high density and no cutting force to achieve the polishing effect. It also requires slow work and fine work, so a barrel-type finishing machine is used.
  • Rubber will age again easily when exposed to water and air. Therefore, we need to dry the water immediately after polishing.

6. Final summary
  • In this case, we demonstrate a process of using spherical ceramic deburring media and high-density porcelain polishing media to remove the parting line from the rubber O-ring surface.
  • This process is also suitable for parting lines removing and polishing of injection molded parts, 3D printed parts, souvenirs, craft gifts and other products produced from silicone, fluorine rubber, nitrile rubber, Teflon and other materials.
