Compared with bonded abrasives, coated abrasives have the following processing characteristics:
1. Soft performance:
Softness is the most important feature of coated abrasives. It can be folded, bent, rolled and cut into various shapes to meet different processing needs.
2. Sharp micro-edges of abrasive grains:
The electrostatically planted abrasive grains are implanted into the adhesive layer perpendicular to the surface of the substrate, with the abrasive grain tips facing outward and evenly distributed, forming sharp micro-edges. Therefore, the grinding efficiency is high and the grinding surface texture is uniform.
3. Strong abrasive holding force:
Under the action of the continuous electric field force in the electrostatic field, the abrasive particles have a relatively large kinetic energy and are deeply embedded in the adhesive layer. After the adhesive layer solidifies and dries, the abrasive particles have sufficient holding force and are not easy to fall off during grinding. Coated abrasive tools do not have the problem of "self-sharpening" during the grinding process, and new belts are replaced after dulling.
4. Easy and safe to use:
The coated abrasive is light in weight, easy to carry and replace, does not require balancing after tapering, and does not require rest during use.
5. Simple equipment:
Coated abrasives require simple equipment, are easy to manufacture, low in cost, and easy to automate. The sanding belt is light and has a vibrating pin. Because it is soft and insensitive to vibration, the rigidity requirement for the equipment is low.
6. Stable belt cutting speed:
Abrasive belts exhibit minimal wear during use and can maintain a stable grinding speed over time, a key feature. Most metals are sensitive to changes in grinding wheel speed when machining with bonded abrasive tools, especially when machining small curved surfaces or performing high-precision machining. The belt's stable grinding speed is ideal for high-precision grinding operations.
