Precision Scale Knob Turned Parts

This precision scale knob is made of 7075 aluminum alloy as raw material, with a cylindrical shape and a smooth surface with a running texture. The outer edge is marked with clear digital scales for precise setting and reading; The central region is formed in the form of a circular channel which has a plurality of through openings and positioning openings of different diameters, used for mounting and fastening or connection to the transmission mechanism.

First, the high-precision lathe with CNC on aluminum mounts 7075 is executed on a lathe. Complete the shaping of the external contour,  center hole, and installation hole of the knob in one go, with strict control of key measurement tolerances in the range of ± 0.01 mm, to ensure a precise approach to the support material.

After finishing the turning, the teeth and scale of the knob are finely processed by a carving machine to ensure that the scale is clear, is evenly distributed and easy to read and precisely edit. Subsequently, a number of polishing processes are carried out to gradually improve the smoothness of the surface until a soft metallic gloss occurs.

The final process uses a natural anodizing to form a uniform and dense oxide film on the surface of the aluminum workpiece. By maintaining the original metallic texture of the aluminum alloy, it greatly improves its surface hardness, wear resistance and corrosion resistance. This entire process fully demonstrates the company’s technical strength in the field of Precision CNC Turning Services
