characteristics of the organic abrasive

Using a wide range of organic abrasive, has a combination of flexibility and high strength, and has good polishing properties. In the rough, fine, fine, throwing, etc. have been applied in the grinding process, the resin abrasive has the following characteristics:
1, the combination of high strength
Compared with ceramic binder, resin  grinding wheel binder is high strength, its resin grinding wheel speed of 80 ~ 120m / s, and can withstand greater pressure grinding. Heavy-duty grinding wheel pressure up 10 × 104 ~ 40 × 104N, widely used in iron and steel industry, such as various steel ingot, billets and other snagging processes. Dedicated high-speed heavy-duty wheel and other coarse machining with safe operation, suitable for high speed grinding and large feed grinding, grinding efficiency.
2, with a certain degree of flexibility
Relative ceramic abrasive resin abrasive with good toughness, a certain plasticity and ductility. The elastic modulus (E) several times lower than ceramic. Therefore, the resin abrasive suitable for the preparation of a variety of sheet wheel and high-speed cutting wheel. Also, because a certain degree of elastic deformation, the grinding force can be buffered. Thus grinding effect, a polished effect, can improve the surface roughness.
3, can be made into a variety of complex shapes and special requirements of abrasive
Hardening of the resin bonded abrasives low temperature curing at normal temperature, shrinkage is small, can be made of the special requirements of complex shapes and abrasive. Such as: the use of glass fiber reinforced resin grinding wheel, easy to chip, good heat dissipation porous resin grinding wheel and the groove; improved grinding wheel bolts conditions, electrolytic grinding wheel, polishing wheel; and a cylindrical bowl shaped, butterfly and other shaped grinding wheel.
4, for a wide range
Since the new resin bond varieties, can be made  Abrasive paper into a variety of strength and performance of resin abrasive. Therefore, can be widely used in waste grinding, rough grinding, cutting, semi-fine grinding, grinding, polishing and other processes. Resin abrasive combined with high strength, high speed, impact resistance, and a shortage of suitable coarse grinding; resin abrasive with good toughness, suitable for cutting processes; resin abrasive Good elasticity, has some polishing, available for grinding and polishing. Resin abrasive lower heat resistance, easy to wear, suitable for surface grinding and fine grinding.
5, and prevent burns workpiece to be ground
Low heat resistance resin binding agent, can reduce or avoid the phenomenon of burn the workpiece. The workpiece in the heat generated during the grinding, the first carbonization of the resin to promote passivation of the abrasive fall off, exposing new abrasive sharp, reducing the grinding area of ​​the heat, to avoid workpiece burn.
6, low temperature curing resin abrasive, short production cycle, simple equipment
Conducive to specialized production. The  Sanding Sheets disadvantage is that:
(1) resin abrasive alkali resistance, water resistance is poor, easy to aging. Generally be kept for one year. Thus, not long-term storage.
(2) low heat resistance resin abrasive, grinding machining, wear larger shape suitable for form grinding.
(3) low porosity resin abrasive, processing smell, should pay attention to environmental pollution problems.
