There are many grinding wheel breakage causes. Many people think that the quality of grinding wheels is poor. In fact, the crack of the grinding wheel is caused by many reasons. Of course, the quality of the grinding wheel may also be among them. Other, the rupture of the grinding wheel is also related to the storage and transportation and the using method of the grinding wheel.
Breakage caused by cracking of the grinding wheel
Problem 1: When the grinding wheel hole is small or the shaft is big, fix the grinding wheel toughly.
Solution: The shaft should be loaded smoothly in the grinding wheel holes, not rigidly loaded.
Problem 2: Uneven support of the flange(flange bending, lead filling layer protruding, flange burr, uneven grinding surface)
Solution: The left and right sides of the grinding wheel flange should be finished to the specified correct and smooth size. The flat part of the grinding wheel is precisely processed, and the lead filling layer cannot protrude flat.
Problem 3: The tightening force of the nut is too large.
Solution: If the force of the tightening the nut of the flange is too big, the flange will be twisted, so that the local force of the grinding wheel is large, so it should be properly tightened.
The linear velocity of the grinding wheel is too large
Problem: When the rotation speed of the grinding wheel shaft is too high, use the grinding wheel with a larger diameter.
Solution: Change the speed of the grinding wheel shaft, use the grinding wheel with a small diameter.
When the imbalance of the grinding wheel is too large
Problem 1: The balance check from the grinding wheel factory is insufficient.
Solution: Correct the balance again on the balance stand.
When the strength of the grinding wheel is small
Not allowed to use the grinding wheel for siding except the side.
Insufficient inspection of the grinding machine or improper machine tool
Problem 1: The bearing is loose, and the spindle is bent, and the precision of the grinding machine is significantly reduced.
Solution: Check and repair the grinding machine to improve accuracy.
Problem 2: The shaft diameter of the grinding wheel is too small.
Solution: Use the grinding wheel that size is the same as the shaft.
Problem 3: Rough grinding or wrong using of grinding wheel
Solution: Correct grinding with the guidance of the skilled person or grinding wheel instruction manual.
Side grinding with an unsuitable grinding wheel
When using the grinding wheel other than the side grinding, should use the grinding wheel for side grinding (cup grinding wheel,etc.)
Qualitative change of grinding wheel
Problem: When the grinding wheel encounters flood or fire, the resin bond and rubber bond grinding wheel should qualitative changes.
Solution: Confirm the way of grinding wheel enters. The correct storage should consider the date of manufacture of the grinding wheel and strictly check the inspection before using it.
Problem: The quality of the grinding wheel is not good, and the grinding wheel is pressed by heavy objects, and improper installation of the grinding wheel.
Solution: Ensure the product quality, and the heavy objects are not allowed on the grinding wheel and install the grinding wheel smoothly.
Conclusion of Grinding Wheel Breakage Causes and Solutions:
Carefully check the grinding wheel and grinding machine before using the grinding wheel, and strictly enforce the operating rules.
