(2) rough polishing: polishing a cloth wheel, roughly polishing by using 600# polishing wax, and polishing and flattening the surface of the product;
(3) fine polishing: polishing a cloth wheel, namely finely polishing by using 1000# polishing wax to increase the surface glossiness of the product to 600 ℃;
(4) light receiving: polishing the cloth wheel, namely slightly polishing the whole product by using 1200# polishing wax to reduce the silk mark of the cloth wheel;
(5) anodizing: using polishing liquid to perform highlight treatment on the surface of the product, removing the cloth wheel silk print, and enabling the glossiness of the product to be 700-800 ℃;
(6) anode: and (5) carrying out anode production on the product to form the color required by the customer.
The traditional process is easy to have the following defects:
firstly, the polishing single-process flow is long, so that the polishing cost is high;
secondly, the polishing single process has a long process flow, so that the turnover frequency of the product materials is too high, the rotating shaft product is easy to be scratched and bumped in the rotating shaft process, and the bad proportion is about 8%;
and thirdly, the polishing process can be finished only by sanding, rough polishing, fine polishing and light receiving actions, the sanding action, the rough polishing action, the fine polishing action and the light receiving action are all manual operations, and the surface quality of a polished product is often unstable due to human factors.
