Identification of polisher quality

polishing machine is an electric tool. The polishing machine consists of basic components such as a base, a polishing disc, a polishing fabric, a polishing cover and a cover. The motor is fixed on the base, and the taper sleeve used to fix the polishing disc is connected to the motor shaft through screws. The polishing fabric is fastened to the polishing disk through a ferrule. After the motor is turned on and started through the switch on the base, the sample can be polished by applying pressure to the sample by hand on the rotating polishing disk. The polishing fluid added during the polishing process can flow into the square plate placed next to the polishing machine through the drain pipe in the plastic plate fixed on the base. The polishing cover and cover can prevent dust and other debris from falling on the polishing fabric when the machine is not in use and affecting the use effect.
In polishing machine quality appraisal cases, Zhongke Testing can provide polishing machine quality appraisal services.
