Drum polishing machine

Drum Polishing machine is a mechanical equipment commonly used for surface treatment of hard materials such as metals, plastics, ceramics, etc. Its main Working Principle is to drive the workpiece placed in it to rub against polishing abrasives (such as polishing grinding stones, polishing paste, etc.) through the rotation of the drum, thereby removing burrs, oxide layers, scratches, etc. on the surface of the workpiece, and improving the smoothness and glossiness of the workpiece surface.

A drum polishing machine usually consists of the following parts:

Drum: It is the main part of a polishing machine, usually made of stainless steel or special wear-resistant materials. The inner wall of the drum has spiral blades to push the mixture of workpiece and abrasive to roll inside the drum.

Electric motor: provides rotational power for the drum.

Control box: used to control the start, stop, speed adjustment and other functions of the electric motor.

Feeding and discharging system: facilitates the addition of workpieces and abrasives, as well as the removal of polished workpieces.

Cooling system: Due to the large amount of heat generated during the polishing process, the cooling system is used to maintain the polishing machine at a suitable temperature and prevent the workpiece from deforming due to high temperatures.

Drum polishing machines can be classified into various types based on their structure and purpose, such as horizontal drum polishing machines, inclined drum polishing machines, vibrating drum polishing machines, etc. They are widely used in various manufacturing industries, such as hardware, jewelry, automotive and motorcycle parts, electronic components and other industries in the production process.
