Inner hole deburring method:

Inner hole deburring is always a difficult problem in workpiece processing. According to my practical experience, several practical and feasible methods of inner hole deburring are introduced.

6 ways to deburr the inner hole:

1 Fluid polishing deburring: physical deburring, the grinding medium is a semi-fluid soft abrasive, through the piston pressure, so that the soft abrasive flows through the inner hole, continue grinding, and then reach the role of removing the inner hole burring. After the inner hole burrs are removed, rinse with water.

2 Electrolytic polishing deburring: The use of positive and negative electrodes to clamp one end of the workpiece, electrolytic effect after power, remove the inner hole burring. The advantage is that the speed is fast enough, the defect is that the area around the burr may also form corrosion, affecting the product precision.

3 Magnetic polishing deburring: Use a very fine, magnetic steel needle to deburring the inner hole. It is possible to perform large volume polishing operations, the problem is that if the burr hardness is high, it may not be completely removed. deburring

4 Oscillation polishing deburring: Select a fine solid polishing stone with high hardness, put it in the cylinder together with the workpiece, quickly oscillate, and then reach the deburring effect. At present, this method is only applicable to the workpiece with brittle burrs, and the scope of application has greater limitations. Deburring machine

5 High pressure water polishing deburring: Use the instantaneous impact force of high pressure water beam to remove burrs in the hole. At present, it is used in the field of automobile engines, but because the impact force of high-pressure water beam is very strong, it may damage the workpiece itself, and it is necessary to evaluate its own workpiece before application.

6 Thermal polishing deburring: a relatively environmentally friendly inner hole deburring program, the use of hydrogen and oxygen incineration to produce high heat, instant oxidation of inner hole burrs, at the same time, the oxidized burrs will also be attached to the workpiece, the need for secondary processing, remove attachments. Before using this method, it is necessary to know whether the workpiece can accept high temperature.

Matters needing attention

Before using the method of inner hole deburring, it is necessary to carefully evaluate your workpiece, evaluate the material, scale, shape, etc.
