1, fluid polishing deburring: physical deburring, the grinding medium is semi-fluid soft abrasive, and the soft abrasive flows through the inner hole to continue grinding through piston pressure, thus achieving the deburring effect of the inner hole. After the burr of the inner hole is removed, it needs to be washed with water.

2. Using the deburring process of polishing machine and deburring magnetic grinder, put the workpiece into a barrel filled with abrasive and grind it for 3- 15 minutes. It can remove all the fine burrs of precision parts, make the surface of the workpiece smooth and flat, and bring unprecedented high quality to users. And the precision of the product will not be affected.

3. Ultrasonic deburring is not suitable for all burrs, mainly for some microscopic burrs. Generally, if you need to observe burrs with a microscope, you can try to remove them by ultrasonic.
