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
  • This stainless steel deep drawing stamping hardware parts product is formed from stainless steel thin plate through deep drawing of mold. There are sharp burrs on the upper end after cutting, but the wall thickness of the finished product is very thin, which can easily cause deformation of the workpiece during polishing. Therefore, the rough finishing machine adopts vibrating bowl finishing machine, which has moderate finishing force and high cutting efficiency. Abrasive media uses heavy-cutting triangular silicon carbide deburring media, which can quickly remove burrs, stretch line marks and wrinkles.
  • Fine finishing uses light cutting force cone-shaped plastic media, also called resin media. This abrasive 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 polisher with precision finishing media to enhance the brightness and mirror polishing.

5. Additional instructions
  • The gearbox housing is produced by high-pressure casting of aluminum alloy. The product has high precision and a smooth surface, but burrs and flashes will appear on the edges and holes of surface, which need to be polished. Therefore, a finishing process combining rough deburring, deflashing, descaling and cleaning is adopted. The rough finishing adopts a vibratory finisher with medium cutting force cone plastic media. The sharp angle of the tumbling media can reach into the grooves, corners and inner walls to remove burrs and flash.
    A vibratory polishing machine is used for cleaning. The abrasive media is made of precision finishing material without cutting force angle cut cylinder porcelain polishing media. This tumbling porcelain media 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 vibrating dryer with corn cob drying media to absorb moisture and dry the inner and outer surfaces.

5. Additional instructions
  • Copper alloy floor outlets have low hardness and are medium-sized product parts with a large daily processing quantity. Therefore, a vibratory polishing machine is used with a cone plastic media with low hardness to perform rough finishing. The conical tip can touch deep into the groove to remove burrs and chamfers.
    Fine polishing and brightening is also achieved by using a vibrating finishing machine, with spherical white corundum finishing media with high hardness and light cutting force, which can cut a small amount, further reduce the roughness and improve the surface brightness.
  • In order to improve the anti-rust and anti-corrosion performance of the product after water treatment, it is immersed in the anti-rust liquid for anti-rust treatment after polishing. Finally, a vibrating dryer is used to dry the surface moisture and dry it.

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.
