Aluminum Oxide 220 Grit Abrasive Suppliers Thailand

At a higher speed of high purity fused aluminum oxide grinding wheel, the metal removal rate can be increased, the grinding force can be reduced, and the power consumption can be reduced. The higher the speed of wheel, the better the surface roughness of workpiece, so that the tangential and normal grinding forces are reduced, so that the force on a single abrasive is reduced, so that the wear of wheel is reduced, and the aluminium oxide blasting grinding heat is reduced.

The higher grinding ratio of CBN wheel is obtained by using the black aluminum oxide abrasive 70 grit higher grinding wheel speed. If the CBN grinding wheel speed is increased from 35m / s to 50m / s and 60m / s respectively, not only the limit feed speed of the grinding wheel is increased from 20m / s to 35m / s and 40m / s respectively, the grinding efficiency is increased to 369% and 647% respectively, but also the black alumina grinding ratio is increased from 361 to 1331 and 2337 respectively.(aluminum oxide 220 grit abrasive suppliers thailand)

Therefore, the adoption of steel shot abrasive high grinding wheel speed can not only significantly improve the grinding efficiency and grinding ratio of CBN grinding wheel, but also reduce the grinding force, reduce the power consumption and improve the surface roughness of workpiece grinding. When grinding workpieces with low thermal conductivity (such as alloy steel), because the surface temperature of aluminium oxide abrasive grit workpieces is relatively high, it is easy to produce burns and cracks.

(aluminum oxide 220 grit abrasive suppliers thailand)When brown fused alumina grinding thin workpiece, it is also necessary to use the wheel with loose structure and low hardness. Similarly, the speed of CBN grinding wheel has increased from 60m / s to 80m / s, 120m / s, 160m / s and 200m / s. The 240m / s CNC grinding machine with CBN grinding wheel has been used in industrial production abroad. Generally, it is in the range of 0.45-1.8m/min. Select large value for rough grinding and small value for aluminum oxide for sand blaster fine grinding.

In China, CBN wheel is used to grind automobile camshaft and ceramic bond wheel with a diameter of 600mm. The brown aluminum oxide grinding speed of CBN wheel is 50M / s and 60m / s. At present, the hardness of the grinding wheel should be lower than that of the solid workpiece, there is no unified grinding specification for CBN wheel in China. In the 1980s, the recommended grinding speed of CBN wheel was in the range of 15-35m / s. This is mainly due to the limitations of aluminium oxide sandblasting machine tools.(aluminum oxide 220 grit abrasive suppliers thailand)

Because the brown aluminium oxide workpiece speed has little influence on the grinding effect, it can be selected in the range of 10-20 M / min. When fine-grained CBN wheel is used for fine grinding, the speed of workpiece can be increased properly. The selection principle of axial feed rate or axial feed rate is the same as that of ordinary grinding wheel, which can be selected by reference to the grinding of ordinary pink aluminium oxide grinding wheel. A smaller feed should be used for precision grinding.

(aluminum oxide 220 grit abrasive suppliers thailand)At this time, it is necessary to select glass bead abrasive grinding wheels with low hardness and loose structure, and strengthen cooling at the same time, so as to effectively avoid burns of workpieces. When grinding the outer circle of the thin-walled hollow workpiece, which is also to prevent the workpiece deformation caused by the increase of grinding temperature. By increasing the speed of CBN wheel, the surface roughness of workpiece is improved. Selection of black synthetic corundum workpiece speed and feed speed.
