This lens cover for the endoscope has a flat rectangular plate with an overall rounded rectangular shape. The four angles are machined with symmetrical oblique angles by CNC precision milling machines. There is a circular hole in the middle of the cover plate, with a smooth wall and precise dimensions. The surface is first sanded with grating 120 # and then subjected to anodizing in glossy silver. The product has a uniform edge thickness and excellent flatness.
Step 1: First, cut the AL6061-T6 aluminum alloy raw material accurately to eliminate excess edges and angles; restart of the High Precision CNC Milling machine and completion of the integrated milling of complex structures such as flange shape, Central cylinder and installation hole position at once thanks to the predefined digital program. The whole process adopts the high precision CNC Milling technology to control the dimensional tolerance at micrometer level, to ensure a perfect adjustment between the lens cover and the endoscope and to eliminate mounting and precision deviations.
Step 2: Then enter the surface treatment phase. First, use the 120# sand process, which uses compressed air as force to spray small abrasives on the surface of the product at high speed, to remove the machining knife marks and form a uniform and delicate matte texture. At the same time, improve the adhesion of the next oxide layer.
Step 3: Finally, an anodizing of the shiny silver is carried out, to produce a dense and wear-resistant alumina protective film on the product surface by electrochemical reaction. This not only gives the lens cover a uniformly shiny silver appearance, but also greatly improves corrosion resistance and scratch resistance, to meet the requirements of disinfection and cleaning of medical devices while ensuring the biocompatibility and safety of the product.
