What is the polishing principle of the outer cylindrical polishing machine?

The working principle of the cylindrical polishing machine is similar to that of the round tube polishing machine.

 It adopts the principle of centerless grinding and consists of two mechanisms: polishing and feeding. By adjusting

 the feed rate of the grinding head, the workpiece can be ground with a large margin or finely ground. Grinding 

and polishing, by adjusting the distance between the guide wheels, workpieces of different specifications can be

 processed. The feeding mechanism of this machine adopts a stepless speed change device, which can make the

 workpiece achieve the ideal grinding and polishing by changing the feed speed of the workpiece processed by 

the outer cylindrical polishing machine. Effect.and according to the different materials and polishing requirements 

of the workpiece, various polishing tools such as emery cloth wheel, hemp wheel, cloth wheel and nylon wheel can

 be flexibly selected to polish the workpiece. 

The workpiece supporting plate is made of wear-resistant material, so it does not need to be adjusted frequently. 

When the workpiece specifications are changed and adjusted, the machine adopts the structure of "one-way

 movement and two-way positioning", which greatly simplifies the adjustment work of the pallet. The complete 

production line consists of three parts: polishing machine, feeding device and discharging device. And there are 

standard, automatic, environment-friendly and economical models for users to choose from.

If the external polishing machine wants to increase the polishing rate, it must be carried out in two stages, that is, 

rough polishing and fine polishing. The purpose of rough polishing is to remove the polishing damage layer. This 

stage should have a large polishing rate. The surface damage caused by rough polishing is a secondary consideration, 

but it should be as small as possible; followed by fine polishing (or final polishing), Its purpose is to remove the surface 

damage caused by rough polishing and minimize the polishing damage.

Basic working principle of cylindrical polishing machine

When the polishing machine is polishing, the sample grinding surface and the polishing disc should be relatively parallel 

and evenly pressed lightly on the polishing disc, and attention should be paid to prevent the sample from flying out and 

new grinding marks due to too much pressure. At the same time, the sample should be rotated and moved back and forth 

along the radius of the turntable to avoid local wear of the polishing fabric too quickly. During the polishing process, the 

micropowder suspension should be continuously added to keep the polishing fabric at a certain humidity.

The speed of the turntable can be increased appropriately during fine polishing, and the polishing time is appropriate to

 throw away the damaged layer of rough polishing. After fine polishing, the ground surface is as bright as a mirror, and no

 scratches can be seen under the bright field conditions of the microscope, but the wear marks can still be seen under the

 phase contrast illumination conditions. The polishing quality of the polishing machine seriously affects the tissue structure 

of the sample, which has gradually attracted the attention of relevant manufacturers.

Only on the basis of understanding the basic working principle of the cylindrical polishing machine, can it be better operated

 and used to exert its maximum practical effect. With the continuous development of cylindrical polishing machine, it is bound

 to be used in more fields.
