B60 Ceramic Beads Media with RoHS certificates for Abrasive flow Deburring
Description of Ceramic beads for deburring
Ceramic blasting beads is made of imported zircon sand as a raw material and melted in Ore furnace in
temperature above 2000℃,and then blow into micro beads. It is an efficient and environmentally friendly
sand blasting media. Based on the performed tests on Ceramic beads samples by SGS, the result if
Cadmium, lead, Mercury, Hexavalent chromium, PBBs, PBDEs do not exceed the limit as set by
RoHS Directive (EU)

Features of Ceramic beads for deburring
1. Ceramic beads has long service life and high cost performance:
The life of ceramic beads is more than 30 times that of glass beads. Ceramic sand will not wear, only a small amount will be broken into pieces, and the broken ceramic beads will still maintain the original size, shape and hardness. and smooth surface, this is enough to recycle.
2. Ceramic beads does not produce dust. This is enough to effectively reduce the dust content and final waste in the working environment, which can effectively protect the environment from pollution and pose no harm to workers.
3. Ceramic beads has high hardness, long service life, good elasticity and low wear, which can effectively reduce the number of replacement materials and reduce the cost of workers. Whether it is used in dry blasting, wet blasting or shot blasting, ceramic sand can bring high efficiency.
Application of Ceramic beads for deburring
Aluminum alloy work pieces inner holes abrasive flow deburring
Metal deburring is mainly to deal with metal surfaces and internal hole burrs. The burrs on the workpiece are caused by plastic deformation during the cutting process, and some are the flashing of the castings, the forgings, and some of the materials extruded by the welding.
Surface deburring is not difficult, then how about the inner hole deburring?
How to deburr the inner hole for aluminum alloy workpieces with many inner holes and intersecting holes?
1. Difficulties in deburring the inner hole of aluminum alloy workpiece
The heat resistance and acid resistance of aluminum alloy workpieces are not too high, and they are not suitable for compression. These features eliminate many deburring methods. Moreover, it can be seen that these burrs are mainly concentrated near the intersecting holes of the inner hole, and the ultrasonic deburring grinding head can not be found there, and it is barely used, and may not be cleaned. Moreover, in order to maintain the precision of the workpiece, we must also control the polishing margin within a reasonable range when removing the internal hole burr.
Therefore, we must find a way to solve the inner hole, without loss of precision, without damaging the workpiece, and environmentally friendly deburring.
2. Ceramic beads abrasive flow is the most applicable deburring ways of aluminum alloy inner hole
First of all, the abrasive flow is the most suitable process for deburring the inner hole. Secondly, by adjusting the particle size of the abrasive and the polishing time, we can control the polishing allowance. From the enlarged detail view, after polishing the abrasive flow, we no longer need to go through any treatment, which not only solves the problem of internal hole burr, but also improves the polishing effect of 2-3 grades on the original basis of the workpiece. This is unique in all deburring processes.
