Description

Technical Field

[0001] The invention belongs to the field of valve processing, and in particular relates to an outer surface polishing and grinding device for producing faucet valves and a process thereof. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters of the conveying medium. They are often used in conjunction with faucets. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. They have the functions of shutoff, adjustment, flow diversion, backflow prevention, and pressure stabilization.

[0003] The valve needs to go through the processing steps of cutting, casting, welding, etc. during the production process. Since the valve is made of metal, burrs will be generated during production. Therefore, it is usually necessary to polish its surface after the processing is completed. In the prior art, when polishing the valve, the processing personnel usually manually place the faucet on the polishing equipment, and then polish it through the polishing equipment, which not only reduces the production efficiency of the valve, but also is time-consuming and labor-intensive.
