First. The quality of emery cloth directly affects the quality of emery cloth flap wheel. The common problems that will not shine are as follows:

1. Emery cloth has low strength and poor toughness, and a large number of pieces appear in the process of use.

2, The abrasive bonding is not strong, in the grinding process of desarening, cutting ability rapidly decreased, until the loss of cutting ability.

3, The base is not wear-resistant, the abrasive grain have not been fully grinding, and with the fall off, the wheel will wear quickly.

4, According to different grinding material to choose different density of cloth, abrasive and sand, due to improper selection of abrasive cloth, often cause jam, affect the grinding effect, serious will cause the flap wheel scrap.

Second, after the adhesive curing, the strength, bonding performance is poor, or heat resistance is not good, in the grinding process, due to the temperature rise, cause chuck falling off, or flaps fall off in groups.

Third.The chuck with poor rigidity and deforms after receiving pressure and impact, causing the wheel to fail.

Four. Small flaps is arrange too close, elastic, grinding surface and workpiece contact area is small, the cutting efficiency is low, especially the flaps diameter smaller constantly in the process of wear and tear, shorter plates, this kind of phenomenon is very outstanding, so the installation the chuck of flaps wheel shoulds not be too tight, round plates are grouped interval, even some page to increase flexibility.

Five. Uneven density in the assembly of the flaps will cause uneven wear of the flap wheel, resulting in the deformation of the flap wheel, in the grinding process, there will be beating, and even damage the workpiece.

Six. The assembly process of the flap wheel is not reasonable, the flap wheel mounting card should use the flange, the main stressed part should be in the flap wheel and the flaps bonding part, the mounting card does not pay attention to make the chuck deformation, or even fall off.

Seven. Operation process is not reasonable, the new wheel, due to its flap length, good elasticity, abrasive surface and large workpiece contact surface, its cutting force is the best. Therefore, the pressure between the flap wheel should not be too large, otherwise, the flap wheel wear fast, will cause excessive wear of the workpiece, in the actual operation, should be adjusted according to the wear degree of flap wheel grinding workpiece pressure.

Eight. Emery cloth wheel using line speed is generally 20-30m/s, too high line speed will cause the wheel damage, or even rupture.
