How to determine the maximum speed of the diamond grinding wheel

When the high-performance diamond grinding wheel is running, nothing can stop it. According to its operating specifications, the right diamond grinding wheel can cut through concrete blocks or quartz plates. Alternatively, by slowing down the diamond grinding wheel and equipping it with fine-grained gemstones, it can be sliced ​​by glass or tile. In any case, in addition to those diamonds, the working speed of the diamond grinding wheel determines the cutting performance.

Determine the speed limit

As a rule of thumb, technicians use a rotational speed of 50 to 60 meters per second when operating a diamond cutting tool. This difference will vary to accommodate diamond grinding wheel geometry and diamond type variations. The softness or hardness level of the diamond bond matrix also affects the speed of the tool. If the cutting media is dense and full of abrasive elements, expect the diamond grinding wheel to spin more slowly. If the material is soft, such as masonry or tiles, the cutting speed of the diamond beveling tool may increase.

Handling high speed friction energy

So far, these facts have been seen as common sense operator tips. After all, by operating the diamond grinding wheel at speeds above 60 m / s on abrasive and hard cutting media, frictional heat is generated, which is likely to result in tool damage and premature diamond wear. The only way to avoid this problem is to increase the flow of liquid coolant from the device. Yes, these are wet diamond cut off wheels. When using a dry diamond grinding wheel, the disc speed drops below the lower limit of 50 m / s because there is no liquid to keep the diamond cool. Basically, in order to keep everything running, the operator should consult the diamond grinding wheel speedometer in the tool manual or the diamond grinding wheel data sheet.

Manufacturer set diamond grinding wheel tension

In this field of work, not only the geometry of the insert and the rim profile, but also the fact that the diamond and adhesive ageing are affected, not only the minimum and maximum rotational speeds of the insert are affected. In addition to these two short-lived problems, there is also the fact that the metal disc has been specially tensioned so that it can operate normally at the referenced operating speed. If the tool setting exceeds this operating threshold, the tensioned metal may warp and break. Like unbalanced wheels, high-speed swings can cause serious accidents.

Fundamentally, the working speed of diamond grinding wheel must not be ignored. In the best case, the diamond will heat up and wear out. They can rupture and age, and the adhesive can do very similar things. In short, the tool won’t last long. In the worst case, a tensioned cutting disc can create an annoying swing that can compromise its performance. If the swing is intensified, the diamond grinding wheel will warp and break.
