Camillus, NY. Mar 8, 2010. #5. Grinder Wheel Rotation. As pointed out, grinders tend to rotate down toward the tool rest, keeping the tool on the rest. With this rotation the burr forms on top of the tool. This is due to the deformation of the edge on the unsupported top surface of the tool as the wheel moves into it.

Holding the abrasive stick on the grinding wheel face while the wheel turns will "true" the wheel back into round, producing a flat grinding face. To clean or sharpen the wheel, move the dressing stick back and forth across the grinding wheel face. Moving the stick quickly causes the grinding wheel face to be rougher, which results in faster ...

Follow these Steps! 4. Broken Shims. Another reason responsible for the grinding noise when braking is broken shims. A worn-out shim will make a contact with a piece of the braking system, such as the rotor. When metal comes together with other metal like this, they will create a grinding sound from your braking system.

In Conclusion. While they both involve the physical removal of material from a workpiece, milling and grinding aren't the same. The former machining process is characterized by the use of a milling machine, whereas the latter machining process is characterized by the use of a grinding wheel. No tags for this post.

X2, at least the bottom of the inner liner has come loose in one of the pics. As well, there could be a wheel bearing issue, Nissan has issued a TSB on ruining wheel bearings (the bearing rollers/balls get chipped) due to pothole impacts, once the bearing wears loose the wheel will move out of place and can rub and the grinding can be from the bad part too.

When a wheel bearing wears out, it can make a grinding, rubbing, or scraping noise from the wheel while driving as the internal parts wear and cause more resistance. This can increase in sound volume the longer it goes unreplaced. Bad wheel bearings might also make a groaning or rubbing noise when turning—another sign the wheel bearing is bad ...

Grit. Bench grinder wheel grit comes in two different sizes: coarse and fine. This is one of the most distinct differences when it comes to grinder wheels and is important to look at when buying one.
