What is the line speed of the customized metal cutting disc?

6 inch es cutting disc

Today, let us talk about one factor that should be paid attention to when choosing a customized metal cutting disc, that is, “line speed”. The maximum working line speed is specified on the label of the 6 inch es cutting disc. Before use, it must be confirmed whether the spindle speed of the machine tool is within the linear speed range of the grinding wheel.

The linear speed of the grinding wheel generally refers to the “safety speed limit range of the grinding wheel”. It clearly stipulates that the speed of the grinding wheel must not exceed the speed during use, otherwise, it may cause the grinding wheel to burst.

As we all know, each industry has some industry default standards for certain performances on its own products. In terms of the choice of grinding wheel speed, it also has industry standards. For example, the line speed selection of ordinary abrasive grinding wheels, the industry standard is 40m/s-80m/s, in general, the grinding speed of the grinding wheel is higher than 45m/s, which is called high speed grinding. This range is the conclusion that people in the industry have come through long-standing experience and is best suited for general abrasive wheels for machining and grinding.

As for the grinding wheel with super-hard material abrasives, the industry standard is 35m/s for the selection of the line speed. Similarly, this is the same as the choice of the line speed of the ordinary abrasive wheel. This parameter is also obtained through experience and is the most suitable for basic applications. It is also the most recommended. Of course, if you want the line speed to be a little higher and make it more efficient to grind, we can do it. This is not difficult, but it is likely to cause unsafe factors in the grinding wheel. After all, the most suitable for it is the safest, and it is the one that can play its biggest role, carefully consider it.

Although the choice of line speed is only a part of the consideration of the grinding wheel, once the deviation is selected, when the grinding wheel is working, because the rotation speed is too high, it is very likely to cause the grinding wheel to suddenly burst, which will seriously threaten the personal safety of the staff; If the speed is too low, the grinding wheel can’t exert its original efficiency, and it is a waste for itself. Therefore, please don’t underestimate the importance of line speed.

Attachment 1: The formula for calculating the linear speed of the grinding wheel is V = πDN /1000
V is the grinding wheel line speed
π is the circumference ratio 3.14159
D is the outer diameter of the grinding wheel x mm
N is x RPM per minute
The division of 1000 is the unit conversion of the outer diameter of mmmm and the linear velocity of m.
