The grinding wheel is further processed into various forms of polishing wheel, which can be divided into four types: the film type, the stack type, the folding type and the attached shaft type. Emitter type: the sand felt cut into the required size of the rectangular block. The core is surrounded by a radial. The inner ring is bonded with an adhesive, and the density is increased from the outside. Polishing wheel stacking type: the sand felt cut into the required size of a layer of the park, the product of the compression, the density of the inside and outside of the uniform. Fold type: the sand felt cut into the required size of the rectangular block, crumpled into Yuanhuan used in hexagonal steel buckled firmly and. Polishing wheel with shaft type: the sand felt cut into the required size of the rectangular block in the round core around the columns into a radial and inserted into the central axis. Sand felt things appearance with an accuracy of better than cloth, secondary, smooth appearance, wear small, falling sand less, proper to produce large quantities of machine; the disadvantage is due to the abrasive and fiber only by adhesive bonding, bonding points smaller, abrasive shedding phenomenon occurs.

  Above is the processing requirements of various styles of polishing wheel.
