The Reason Of The Unequal Rotation Of The Grinding Wheel

Grinding wheel production process is more complex in the production process to be strictly in accordance with the process of production, otherwise it may cause the wheel error process, and the impact of the use of grinding wheel manufacturers introduced a number of reasons leading to uneven wheel.

Grinding wheel imbalance is mainly caused by the wheel manufacturing and installation is not accurate, so that the wheel center of gravity and the rotation axis does not coincide caused. Grinding wheel imbalance is mainly manifested in two aspects, on the one hand in the wheel high-speed rotation, causing vibration, easy to cause the workpiece surface polygonal vibration marks.

After grinding and curing of the grinding wheel and other processes, its size, shape and the surface of the mutual position accuracy, are not up to the use of technical requirements, must be turning, grinding and grinding, due to objective technical reasons, most of the domestic and foreign use of traditional Knife bowl to turn.

The state generally advocate energy-saving emission reduction, in the firing of ceramic grinding wheel when we have not always forget this point, low-temperature firing can shorten the time, conducive to rapid firing, for energy conservation has a significant effect.

Grinding wheel in the processing and manufacturing industry is very widely used, but the wheel also has a very many types, different types of different processing requirements, each in a wide range of applications, the wheel manufacturers to teach you how to choose the right wheel The

The hardness of the grinding wheel refers to the abrasive grain on the surface of the grinding wheel in the external force off the degree of difficulty. Easy to fall off for the soft, and vice versa hard. The same kind of abrasive can be made into different hardness of the grinding wheel, which depends mainly on the performance of the binder, the proportion of grinding wheel manufacturing process.

When the hardness of the grinding wheel is chosen, the abrasive grains of the grinding process can fall off on their own, revealing new sharp abrasive particles and continue grinding. If the selected grinding wheel is too soft, abrasive particles have not passivation to prematurely fall off, not only increase the grinding wheel consumption, but also to lose the correct shape of the wheel and affect the processing accuracy; if the selected wheel is too hard, abrasive passivation can not come off in time So that the grinding wheel on the surface of the gap between the abrasive dust, resulting in increased grinding force, grinding heat increases, grinding temperature increases, so that the workpiece deformation or even burns, but also to improve the surface roughness, productivity decreased.

Usually, grinding hard materials, the hardness of the wheel should be lower; the other hand, should be higher. Non-ferrous metal toughness, grinding wheel pores easily wear debris, generally not grinding. To grind, you should choose a soft wheel. For forming grinding and precision grinding, in order to better maintain the shape of the wheel accuracy, should choose a hard wheel.
