Technical Field

The invention relates to the field of processing, in particular to a method for processing a card-grabbing sand-blasting coating.

Background

The surface of an accessory clamp used on the laser gyro needs to be subjected to sand blasting coating treatment so as to ensure that the accessory clamp can normally work at a working place. The prior sand blasting coating treatment process is to carry out sand blasting coating treatment on the surface of the grab clamp and then tap the central hole of the grab clamp so as to screw a matched fine screw. However, because the size of the grab is very small, the grab is very difficult to tap after the surface is treated by sand blasting and then is used for tapping, and a tapping tool is easy to break. If the central hole of the grab clamp is tapped firstly and then treated with sand blasting coating, a layer of coating is added in the screw hole, and the matched thin screw is difficult to screw in.
