Resin grinding wheel is a grinding wheel made of resin. According to the abrasive, it is generally divided into ordinary resin grinding wheel and super hard resin grinding wheel.
The ordinary resin grinding wheel is a grinding wheel with white corundum, brown corundum, silicon carbide and other ordinary abrasives as the main grinding component, and the superhard resin grinding wheel is a grinding wheel with diamond or CBN as the main grinding component.
The resin grinding wheel has the characteristics of good elasticity, high strength, low heat resistance, strong self-sharpening, simple production and short process cycle. It is widely used for rough grinding, barren grinding, cutting and free grinding, such as grinding steel ingots, casting burrs Wait.
Resin grinding wheel is a tool with large demand. It is widely used in various grinding operations, such as: surface grinding, external centerless grinding, grooving and internal grinding, etc.
Speaking of this, Jekkir has to tell everyone about the precautions for the use of resin grinding wheels. When using resin grinding wheels, you should follow the following rules, otherwise it will not only affect the grinding quality, but may even cause more serious consequences.
- Before using the resin grinding wheel, be sure to check the product for cracks and dullness, if there is, it cannot be used;
- The speed of the grinding wheel shall not exceed the safe linear speed;
- Do not work with the end face of the grinding wheel;
- When the grinding wheel is processing the workpiece, do not use the lever to push the workpiece to increase the pressure on the grinding wheel;
- Professional dressing tools should be used when dressing the grinding wheel, and the operator should wear protective equipment;
- During the grinding process, the coolant should be selected correctly. If the coolant is not used, there must be a dust-proof device;
- The center hole of the grinding wheel and the center axis of the grinding wheel must match, otherwise it cannot be used;
- The shape and size of the flanges clamped on both sides of the resin grinding wheel must be the same; the diameter must meet the requirements, and there must be grooves on both sides;
- When installing and fixing, it must be tight enough. After installation, start the machine idling for about one minute, and use it after there is no abnormality;
- The pressure should be uniform during grinding and use. It is strictly forbidden to violently collide with the workpiece when the grinding wheel is adjusted and rotated. The knife should be progressively advanced. When cutting large diameter workpieces, the contact surface between the grinding wheel and the workpiece should be reduced.
