The polishing machine is composed of some basic components such as base, polishing disc, polishing fabric and polishing cover. The electric motor polishing machine is fixed on the base, and the tapered sleeve used for fixed polishing disc is also connected with the shaft of the electric motor through screws. The polishing fabric is fixed on the polishing disc by tightening the ring, and the motor can rotate and polish by applying pressure after the power is turned on.

The key to the operation of the polishing machine is to try to obtain a maximum polishing rate, so that the damage layer produced during polishing can be removed as quickly as possible. It is also important that the polished layer does not affect the final observed tissue. The use of coarser abrasives ensures a larger polishing rate to remove the polished layer, which is also deeper. The latter using finer materials, polishing damage layer will be shallow.

For this problem we can polish in two stages to carry out, the purpose of rough polishing is to remove the abrasive damage layer, this stage should have a large polishing rate, for the formation of rough polishing surface damage is a secondary consideration, but should also be as small as possible, the drawing machine followed by fine polishing it is the purpose of removing the resulting damage to a surface layer and then make its damage is reduced to a minimum.

When polishing machine polishing, the specimen grinding surface should be parallel to the polishing disc and evenly pressed on top of the disc. Care should be taken to prevent the specimen from flying out or creating new abrasion marks due to excessive pressure, and to keep the specimen rotating and moving back and forth along the radius of the disc. To avoid too much wear and tear, keep adding micro-powder suspension to keep the polishing fabric moist.

We need to do a check on the environment before using the polishing machine, the operator's hands and feet to keep away from the rotating polishing head, the operator can not step on the power cord or power cord to wrap into the polishing head, in the replacement or installation of light pads must be cut off the power. If the operator has not received professional training or has not learned the safety operating procedures, polishing machine does not operate properly do not go to use high-speed polishing machine.
