How to Use & Install Resin Grinding Wheels

The article offers some suggestions on how to use and install resin grinding wheels properly.

1. Resin grinding wheels must be handled with care during transport. Collision and shock should be prevented. The packaging should be damage free.

2. Resin grinding wheels should be put in order without touching the floor directly and be kept dry and well ventilated.

3. Resin Grinding Wheels should be used in time, because extended storage period may affect grinding performance.

4. Resin Grinding Wheels that have been stored for over a year should be inspected before use.

Do's & Don'ts during Installation

1. Before using resin grinding wheels, check to make sure that there are no cracks.

2. Before installation, check to see the maximum rotation rate and the linear velocity, and make sure the protective device is in good condition.

3. The flange plate on both sides of the grinding wheel should be same in shapes and sizes.

4. While installing and fixing grinding wheels, the degree of tightness should be moderate. When the installation is finished, idle the machine for a minute, if everything is all right, you can use the grinding wheels.

5. The pressure should be well-distributed during polishing process, collision between grinding wheels and workpiece is prohibited. When cutting large-diameter workpiece, the contact surface of grinding wheels and workpiece should be diminished.

6. Cutting discs should be fixed stably. Don't cut overlapped workpieces, because loosening workpieces may collide with the grinding wheels and lead to accidents.

7. The power of a grinding machine and the processed workpiece contacting area have a direct influence on grinding wheel's feeding speed. When the grinding machine's power is low and the processed workpiece contacting area is large, less hard grinding wheels should be used.

8. Polishing the workpiece on the end face of grinding wheels should be prevented in case of accidents.

9. Depressed-center wheels and the processed workpiece shall be beveled at an angle of 30.

Principles in Choice of Resin Grinding Wheels

1. Well organized and proportioned without cracks are the basic elements of a superior grinding wheel.

2. Rotation speed and geometric dimensioning limit deviation are important guarantee for grinding wheel safety.

3. During workpiece burrs polish, only by playing the properties of grinding wheels to the full extent, can it help to improve working efficiency, reduce consumption, and save manufacturing costs.

4. Choice of grit size for grinding wheels has a direct influence on surface finish and grinding effect. Generally speaking, coarse-grained grinding wheels are higher in grinding efficiency, but the workpiece surface will be rough; fine-grained grinding wheels are lower in grinding efficiency, but the workpiece surface will be better.
