7075 Aluminum CNC Turned Parts for Sound Devices

The CNC Turned Parts are made of aluminium 7075 with short cylindrical shape and rounded edges; their envelope are made of matt black metal, with delicate touch and wear resistance; The front side are equipped with dense perforated grille with small holes evenly arranged in the concentric circular die. This type of components are often used in small speakers, microphones and other transmitters or sound collection devices.

Step 1: Use CNC cutting machine to accurately cut raw materials, control the cutting accuracy according to the parameters of the dimensions of the product drawings, and strictly control the parts permissions;

Step 2: High speed turning and milling machine is used to finish the precise processing. The technical team corrects the parameters of the equipment and plans the processing path in advance according to the drawings. First, all the exact dimensions of the product are turned accurately and the shape and position tolerances are strictly controlled, as well as the accuracy of the dimensions; Then synchronize the drilling to make sure the position of the opening is not shifted and the wall of the opening is smooth. After processing, perform complete degradation and bright cleaning of the surface, orifice edges and corners of the product;

Step 3: Polish and polish the detail to obtain a uniform and smooth texture on the surface and to lay a solid foundation for subsequent surface treatment;

Step 4: Adopt a hard oxidation process (light black) to form a hard, dense oxide film that ensures wear resistance, greatly improves the corrosion resistance and surface hardness, and extends the service life.
