How to Determine the Quality of Grinding Wheel Cutting Discs?

 Dec 20-2017

Slicing sheets are commonly used products in daily life, which have great help for industrial production and construction. They have high tensile, impact, and flexural strength. So how can we determine the quality of grinding wheel slices when purchasing?

Storage and preservation requirements for grinding wheel slices

When handling and storing grinding wheel slices, be careful not to collide with them. The resin bond grinding wheel slices and ceramic bond grinding wheel slices are prone to cracks and fractures after collision.

Avoid contact with corrosive gases and liquids, especially resin-bonded diamond grinding wheel slices. Contact with corrosive chemicals will change the performance of the resin.

Due to the aging of the resin, the storage period of grinding wheel slices should generally not exceed one year. Otherwise, it will affect their normal use. If you must use them, you need to conduct relevant safety tests again.

When the grinding wheel slices are not in use, the cooling fluid should be washed off in time to keep the surface of the grinding wheel slices clean and prevent oil-based coolants from penetrating into the interior of the grinding wheel slices, causing imbalances when they are used again.

It is best to store the grinding wheel slices at room temperature and avoid contact with high or low temperatures.

Methods to judge the quality of grinding wheel cutting slices

Check the nameplate and instructions of the grinding wheel cutting slices. The nameplate parameters should be consistent with the 3C certificate.

Observe the outer packaging of the grinding wheel cutting slices. The outer packaging should have clear patterns and no damage. Open the packaging box and observe the appearance of the grinding wheel cutting slices. They should have a uniform color, no obvious wire, and marks on the surface of the plastic parts. The coating on the aluminum castings should be smooth, beautiful, and free from defects. The surface of the whole machine should be free from oil and stains.

Hold the grinding wheel cutting slices in your hand, turn on the power, and frequently operate the switch with your hand to start the tool frequently. Observe whether the on-off function of the stone cutting machine switch is reliable.

When operating the grinding wheel cutting slices, observe whether there are any abnormal phenomena on the TV and fluorescent lamps at the scene to confirm whether the tool is equipped with radio interference suppressors.

When operating the grinding wheel cutting slices, observe the sparks during reversal. The sparks during reversal should not exceed 3/2 of the level. Generally, looking from the air inlet of the tool, there should be no obvious arc on the surface of the reversing device. During operation, there should be no abnormal noise.
