Precision powder metallurgy parts products after casting molding, there are many burrs, flash and other conditions on the surface of the product. How to use mechanical equipment to remove burrs, flash and improve the surface brightness and other processing?
General grinding and polishing process is the use of polishing machine equipment, such as vibration grinding machine, centrifugal polishing machine and other polishing machine, and then mixed brown corundum grinding stone, white corundum abrasive polishing abrasives, first rough grinding deburring processing, and then the use of high-aluminum porcelain abrasives, high-frequency porcelain abrasives and other fine grinding polishing abrasives for fine grinding, hoping to further improve the surface brightness of powder metallurgy parts.
In actual use, there is no problem in the process of coarse grinding to remove burrs, but the effect of fine grinding to improve the surface brightness is very unsatisfactory.
Many friends may encounter this situation, powder metallurgy products after grinding, the surface brightness is not any improvement, no matter what the replacement of abrasive or brightener, the surface is still black, there is no metal bright color. This has also become an urgent problem to be solved in the powder metallurgy industry.
Magnetic deburring polishing machine, the use of magic magnetic field force, conduction of fine grinding stainless steel needle, produce high-speed jumping flow, turning and other actions, in the workpiece hole, dead Angle, seam surface friction, one-time efficient polishing, cleaning and removing burrs and other precision grinding effect. The grinding speed is fast, the average grinding time is about 5 minutes to 15 minutes, the replacement of the workpiece with double processing slots is fast, and the grinding parts can be exchanged during the operation of the machine.
