Polishing machine is the object appearance coarse Department clearance loss, in order to reach the mirror. The key of polishing machine control is to try to get the maximum polishing rate so as to remove the damaged layer as soon as possible when polishing.

The polishing machine is composed of a base, 7906, polishing cloth, polishing cover and cover the basic components. The motor is firmly fixed on the base, and the taper sleeve used for firmly throwing the optical disk is connected with the motor shaft by screws. The polishing fabric is fastened on the polishing disc by a ferrule, and the motor is connected with the power supply through a switch on the base, and after starting, the hand can be applied to the sample to exert pressure on the rotating polishing disc.

In the process of polishing polishing liquid in the tube into a polishing machine by the side plate in the plastic plate drainage on the base of the firm.

Polishing cover and cover can prevent dust and other debris on polishing fabric and use results in stiff with bad luck.

Polishing is divided into two stages, the first is the rough polishing, polishing target is to remove the damage layer, this stage should have the maximum rate of polishing, rough polishing and surface damage formation is a secondary consideration, but also should as far as possible; second is precision parabolic, its goal is to remove the rough polishing and surface damage occurred in gestation to minimize the damage, so that the polishing.

When the polishing machine is polished, the sample grinding surface and the polishing disc should be absolutely parallel and symmetrically pressed on the polishing disc, so as to prevent the sample from flying out and producing new grinding marks due to too much pressure. At the same time, the specimen should be rotating and moving back and forth along the radius of the turntable, so as to prevent the local wear of the polishing material too quickly. During polishing, polishing liquid or other polishing aids are added to make the polishing joint stand positive humidity.

The humidity is too general to weaken the role of polishing grinding, the sample of hard phase metal mixtures and graphite in cast iron phase to produce "trailing" signs of non convex and floating steel; humidity is too small, due to friction will make the sample temperature, reduced lubrication, grinding to lose light and dark spots.

After rough polish smooth, but under the microscope to inspect the intense darkness without light, have worn well proportioned carefully, to eliminate fine polishing. When polishing, the turntable speed can be improved properly, and the polishing time should be suitable for throwing the damaged layer with coarse throwing. After the fine grinding polishing bright as a mirror, but in contrast lighting conditions will still see the marks.

In recent years, a lot of things at home and abroad were studied in the performance of polishing machine, polishing of many new models, a new generation of equipment deployment, is the original manual operation of all sorts of growth become semi active and full automatic polishing machine.
