Diamond cup grinding wheel breakage causes

Diamond cup grinding wheel in the daily processing use often encounters the problem of diamond cup wheel rupture, thus affecting the production of manufacturers, serious cases may be due to rupture and injury and other things happen. At this time, some processing manufacturers will think is the reason is the grinding cup is not good cause rupture diamond cup wheel rupture has many factors caused, such as diamond cup wheel in the processing of the use of methods and storage and other reasons. Today, for you to analyze the five core problems of diamond cup grinding wheel rupture and program countermeasures.

Here is the content list:

l Cracking of diamond cup wheels produced by the cracking of diamond cup wheels

l Inadequate inspection of the grinding machine or inappropriate machine tools

l Improper spindle diameter and diamond cup wheel bore diameter

l Change of diamond cup wheel quality

l Storage of diamond cup wheels

Cracking of diamond cup wheels produced by the cracking of diamond cup wheels

Problem: When a shim is needed, there is no shim or the diameter of the shim is too thin after it is used.

Solution: Use shims with high strength and large diameter.

Problem: The tightening force of the nut is too large.

Solution: The tightening nut of the flange is often tightened with too much force from the idea of really wanting to clamp the diamond cup wheel, but tightening with too much force will distort the flange and make the local force of the diamond cup wheel large, so it should be tightened moderately.

Problem: Abuse the cup wheel by considering only the grinding power.

Solution: Since the strength of diamond cup wheels with coarse grain size or low hardness is particularly small, care is needed when grinding with efficiency as the main focus, such as heavy grinding.

Inadequate inspection of the grinding machine or inappropriate machine tools

Problem: Loose bearings, bent spindles, and a significant decrease in the accuracy of the grinder.

Solution: Check and repair the grinding machine and seek to improve its accuracy.

Problem: The shaft diameter of the diamond cup wheel shaft is too small.

Solution: If there is a diamond cup wheel of comparable size to the shaft, use a diamond cup wheel comparable to it.

Problem: Rough grinding or incorrect use of the cup grinding wheel.

Solution: Rely on the guidance of a skilled person or the instruction manual for the use of the diamond cup wheel to perform proper grinding operations.

Improper spindle diameter and diamond cup wheel bore diameter

Problem: The diamond cup wheel bore diameter is too small compared to the standard size and is forced onto the spindle.

Solution: Have a proper clearance between the diamond cup wheel hole and the spindle and strictly forbid to force-fit into it and enlarge the diamond cup wheel hole.

Change of diamond cup wheel quality

Problem: When the diamond cup wheel encounters flooding or fire, the resin bond, rubber bond diamond cup wheel, etc. should start a qualitative change.

Solution: Confirm the way the diamond cup wheel enters, keep it correctly considering the year of manufacture of the diamond cup wheel, and strictly carry out all checks before use.

Storage of diamond cup wheels

Abrasive wheels should not be stored in places that are susceptible to moisture, freezing, and high temperature; rubber wheels should avoid contact with oil; resin wheels should be stored for one year; wheels that have been stored for more than one year should undergo strict inspection and be confirmed to be problem-free before use.
