Introduction to resin wheels and precautions for using resin wheels

2019-11-11 1418

Resin grinding wheels are grinding wheels made of resin, which are generally divided into ordinary resin grinding wheels and superhard resin grinding wheels according to their abrasive properties.

Ordinary resin grinding wheels are grinding wheels mainly composed of ordinary abrasives such as white corundum, brown corundum, and silicon carbide, while superhard resin grinding wheels are grinding wheels mainly composed of diamond or CBN.

Resin grinding wheels have the characteristics of good elasticity, high strength, low heat resistance, strong self sharpening, simple production, and short process cycle. They are widely used for rough grinding, rough grinding, cutting, and free grinding, such as grinding steel ingots and casting burrs.

Resin grinding wheel is a tool with a high demand, which is widely used in various grinding operations, such as surface grinding, cylindrical centerless grinding, slotting, and cylindrical grinding.

When using resin grinding wheels, it is necessary to follow the following rules, otherwise it will not only affect the grinding quality, but may even cause more serious consequences.

1. Before using resin grinding wheels, it is necessary to check the product for cracks and hoarse sounds. If there are any, they cannot be used;

2. The rotational speed of the grinding wheel shall not exceed the safety line speed;

3. Not working with the grinding wheel end face;

4. When processing workpieces with a grinding wheel, do not use a lever to push the workpiece to increase the pressure on the grinding wheel;

5. When dressing grinding wheels, professional dressing tools should be used, and operators must wear protective equipment;

6. When grinding, the correct choice of coolant should be made. If coolant is not used, a dustproof device must be installed;

7. The center hole of the grinding wheel and the center axis of the grinding wheel must match, otherwise they cannot be used;

8. The flange plates sandwiched on both sides of the resin grinding wheel must have the same shape and size; The diameter should meet the requirements, and there should be grooves on both sides;

9. When installing and fixing, it is necessary to ensure that the tension is moderate. After installation, start the machine and idle for about one minute. Only after there are no abnormalities can it be used;

10. The pressure applied during grinding should be uniform, and it is strictly prohibited for the grinding wheel to collide violently with the workpiece during adjustment and rotation. The feed should be gradual and the contact surface between the grinding wheel and the workpiece should be reduced when cutting large diameter workpieces.
