Share 6 routine inspection methods for grinding wheel cracks
1) Visual inspection
Check the surface of the grinding wheel directly for defects and breakage with the naked eye or other utensils.
2) Acoustic inspection (percussion inspection)
Gear grinding machine grinding wheel manufacturers share that the grinding wheel is placed vertically on a flat hard ground (the small grinding wheel can be suspended through the center hole), and lightly tapped with a small wooden hammer weighing 200-300g.
The percussion point is 45o on both sides of the vertical center line on either side of the grinding wheel and 20-50mm away from the outer edge of the grinding wheel. After the point is percussed, rotate the grinding wheel for another 45o and strike again.
If the sound is clear and clear, it means that there is no crack, and it can be used. If the sound is dull or hoarse, it means that there is a crack, and it is strictly forbidden to use it (the grinding wheel to be inspected must be dry and free of attachments).
3) Check with the markup
According to the marks pasted on the grinding wheel, check whether the abrasive, bond, particle size, structure, hardness, shape and size of the grinding wheel meet the requirements for use.
4) Validity issue
The new grinding wheel taken from the warehouse is not necessarily a qualified grinding wheel, and even the new grinding wheel bought from the manufacturer is not necessarily a qualified grinding wheel.
Any grinding wheel has a certain validity period. If it is used within the validity period, it is a qualified grinding wheel; if it is used beyond the validity period, it is not necessarily a qualified grinding wheel.
The regulations stipulate that "grinding wheels should be used within the validity period, and resin and rubber bonded grinding wheels must undergo a rotation test after being stored for one year, and those who pass the test can be used."
5) Texture issues
During use, if cracks are found in some parts of the grinding wheel, stop using it immediately and replace with a new grinding wheel to avoid accidents caused by broken grinding wheels.
6) wear problem
Gear grinding machine grinding wheel manufacturers remind that any grinding wheel has its certain wear and tear requirements. When the wear condition reaches a certain level, it must be replaced with a new grinding wheel.
