Mirror polishing technology of stainless steel dental probe for precision dental medical equipment parts
How to deburr, descale, and mirror-polish stainless steel dental probe parts for precision dental medical equipments?
The main materials used in the production of precision medical devices and parts are stainless steel, alloy steel, titanium alloy, nickel-titanium alloy and other metal materials. Due to their special uses, the surface must not have tiny pits, scratches and other defects, otherwise it will cause bacteria to grow and affect the patient’s life safety. Therefore, the mirror polishing process of the product surface is particularly important. In this case, we will share the process technology and method of automated and efficient deburring, descaling, brightening and mirror polishing of a stainless steel dental medical device part such as a dental probe. This finishing process solution is also applicable to the mirror polishing of precision medical equipment accessories made of other metal materials.

5. Additional instructions

The dental probe is made of stainless steel. After annealing, there is a thick oxide layer on the surface of the product, the color is black, and there will be slight burrs on the edge of the hole. It is necessary to remove the burrs, oxide scale, reduce the surface roughness, and further improve the brightness. Therefore, the finishing process combining rough deburring, descaling and fine finishing and mirror polishing is adopted. The polishing machine uses centrifugal barrel finisher with heavy cutting force angle cut cylinder ceramic tumbling media. The sharp angle of the ceramic deburring media can reach into the grooves, corners, and inner walls to achieve the effect of removing burrs and oxide layers.
Fine finishing 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, which can further reduce the surface roughness.
In order to improve the anti-rust performance of the product after water treatment, after fine finishing, use a centrifugal spin dryer to dehydrate and dry the moisture on the inner and outer product surfaces. - For mirror polishing, use walnut shell mirror polishing media and polishing paste to achieve a mirror-like surface effect.
6. Final summary
- In this case study, we demonstrated the process of automated surface deburring and descaling of stainless steel probe used in the dental medical industry to achieve mirror polishing.
