The Precision Sliding Metal Bracket CNC Milling Parts are made of 7075-T6 high-strength aluminum alloy and have a Y-shaped symmetrical layout. The main body is a longitudinal support trunk with double screw mounting openings at one end (fixed spacing); The other end is divided into left and right parallel arms, and the insides of the two arms are symmetrically machined with guide slots of full length. The groove width and depth are adapted to the size of the sliding part; Each end of the two arms is equipped with a circular through-hole for the assembly of limit pins or shaft sleeves;A trapezoidal weight reducing hollow window is opened in the middle, and the transition area adopts continuous rounded corners without sharp edges.
Step 1: Choose the 7075-T6 aluminum alloy plate, CNC precision cut according to the contour of the bracket and perform aging treatment on the blank to eliminate the internal force and avoid deformation during post-treatment, thereby ensuring consistent hardness and flatness.
Step 2: Use a high-precision machining center to perform multi-faceted linked milling, wherein the thick and fine machining of the Y-shaped contours, the sliding groove, the mounting openings and the positioning surfaces are closed at once; Based on the mature experience of Metal Milling Service, we strictly control the parallelism of slot positions, coaxiality of drilling positions and contour tolerances, to ensure the sliding precision and the adaptability of the fitting.
Step 3: Double deburring and rounding the milled corners, slots, and hole walls manually and mechanically to eliminate sharp edges and prevent scratching the sliding parts; Additional polishing improves the smoothness of the contact surface and creates the basis for the anodizing pretreatment.
Step 4: After degreasing, degreasing, sandblasting, or mirror pre-treatment of the bracket, it is subjected to hard anodizing to form a uniformly thick oxide film, greatly improving surface hardness, wear resistance, and corrosion resistance. Different colors can be customized as needed to balance performance and appearance.
Step 5: Perform a complete inspection of the dimensions, shape and position tolerances, surface smoothing and the sliding performance of the trim by means of a coordinate measuring tool, a rugosimeter and a sliding simulation tool. Based on the quality standard of CNC milling parts, ensure that each product meets the requirements for the use of precision equipment. Only after inspection can it be packaged and stored.
