Endoscope Base CNC Milling Part

The base of the endoscope is made of high-strength aluminum alloy AL6061-T6 by High Precision CNC Milling and has a uniform rectangular plate structure. A central forest combined with a U-split ensures precise positioning and secure closure of the optical components. The flush feet and the symmetrical threaded bores allow for flexible installation. The surface receives a 120# sandblasting, followed by a glossy silver anodizing that provides a matte metallic surface. Internal reinforcing nerves and weight reduction cavities optimize endurance and reduce mass to a minimum. Specially designed for high precision medical devices, it meets the stringent requirements of repeatable positioning, Dimensional stability and compatibility with sterile environments.

Step 1: In the machining phase, ballets made of solid aluminum alloy 6061-T6 are used and cut precisely with a CNC sawing machine. The dimensional error of the billets is controlled to ± 0.1 mm to ensure consistency with the drawing height and to form a precise basis for subsequent processes.

Step 2: Then firmly fix the blank on the CNC machining center worktable and enter the CNC Milling process: After the blank is firmly clamped, it is first roughly milled with a large-diameter flat bottom knife to quickly remove the excess and preliminarily form the base contour and convex platform; Then use a medium diameter cutting tool to semi precision mill the side wall, installation surface, positioning holes, and groove positions of the convex platform, leaving a uniform margin for precision machining; Finally, all mating surfaces, hole positions, and chamfers are precision milled with small diameter cutting tools to strictly control flatness, hole coaxiality, and positional tolerances within ± 0.005mm.

Step 3: After milling, remove the edges with ultrasonic cleaning and manual disposal. Next, the sand treatment of 120 # is carried out to form a uniform matte surface and improve the adhesion of the oxide film; By anodizing in glossy silver, a dense aluminum oxide film is produced, which provides corrosion resistance, improves wear resistance and biocompatibility while maintaining the metallic gloss according to the standards of medical equipment. The entire process uses the Precision Milling Service, with cutting parameters and high-pressure cooling optimized depending on the properties of the aluminum alloy, to avoid thermal deformation and ensure consistency between size and appearance.
