Chemical polishing is a method of eliminating abrasion marks and leaching and levelling by the selective dissolution of chemical reagents on the uneven areas of the sample surface. Read More

The fluid polishing process (abrasive grain flow process), compared to conventional mechanical processing methods, has the following characteristics. Read More

Plasma polishing machine as a new polishing process, is a development trend of stainless steel polishing Read More

The surface of the workpiece shows residual chips and very fine microscopic metal particles on the surface, these are called burrs and the more burrs there are, the lower their quality standard, they travel in cutting, grinding and other similar chip processing processes. Read More

Sandblasting is a process of surface treatment of workpieces. Compressed air is used as power to form a high-speed jet beam to spray material (copper ore, quartz sand, emery, iron sand, sea sand) at high speed onto the surface of the workpiece to be treated. Read More

Ultrasonic polishing can be divided into the following categories according to the construction of the abrasives used and the processing method Read More

Grinding and polishing are different treatmentsGrinding processing refers to the use of abrasive particles coated or embedded in the research tool, through the relative movement of the research tool and the workpiece under a certain pressure on the processing surface for finishing processing.

Mirror polishing is a polishing process that gives a mirror effect to the surface of a product. The process is commonly used for lift cabins, aerospace equipment parts, moulds, automotive parts, medical machinery, decorative items, etc. Such products require a glossy appearance. The surface after polishing treatment is scarless, bright, smooth, no relief, no metal disturbance layer, no crater like mirror surface state, is the ideal mirror polishing effect. Read More

Metallographic specimens need to be polished after grinding, in order to remove the abrasion marks and deformation layer produced by the grinding process on the specimen, so that it becomes a smooth mirror surface. The current methods of polishing specimens are mechanical polishing, electrolytic polishing, chemical polishing and compound polishing. The most commonly used polishing method is mechanical polishing. Read More
