The edge of the chip is uneven and not smooth, and the loss of direct end-face coupling is large. In order to achieve end-face coupling, we need to smooth the end of the chip. The most commonly used grinding and polishing method is to use a grinder, fix the product in a fixture, place it on a grinding disc, add an appropriate amount of grinding fluid, use the rotation of the grinding disc to produce friction with the product, and control the grinding time to achieve the purpose of thinning, flattening, and chamfering.
