Yesterday, after a hard argument with a friend about the proper installation of the cutting disc on the grinder, I decided to write an article, and dot the Y.
Hundreds of articles on the internet and in each his arguments in favor of one or another version. I believe that my opinion the right thing! )) (Otherwise it can not be). All consonants and not quite please write in the comments your thoughts, and the main reasons that would not be unfounded.
So, let's begin...
Two sides of the disc, what's the difference?
The back side of the disc is open, abrasive, on it there is no notation. On the other hand, the front side of the label or the image to be a disk name and its basic characteristics. On the same side to be himself "decoy" dispute - crimp the metal ring.
The functions of the metal crimp ring (washer).
This ring serves to increase the bearing area of a disc with a clamping nut, for load balancing and maintaining the integrity of the cutting disc during tightening of the nut itself. Also, the compression ring is a kind of protection against boiling of the presser nut with an abrasive surface. It allows without too much trouble to change the drive on the grinder at any time.
Advantages installation disk image and the ring outwardly.
As you may have guessed from the title, I am in favor of the version that correctly placing the disk image and the ferrule outwards.
No specific direction of rotation of discs do not have, so special recommendations from manufacturers, which side to install the cutting disc, no. But the difference - huge!
- It facilitates the replacement disk.
Setting ring disc outwardly facilitates loosening the clamping nut when the disc is replaced (by abrasive structure spin nut harder). As well, there are several other advantages of this installation of the cutting disc.
- Ensures a smooth installation disk.
The compression ring increases the bearing area when twisting the tightening nut. When tightening there is a uniform load distribution on the disc and prevents breakage. It also guarantees a smooth installation disk to support washers.
- Convenience and informative during installation.
When installing outside of the disk image and the ring in your mind is the information always with the characteristics and drive parameters, such as for what material it is intended (metal, concrete, stainless steel ...), a diameter, maximum permissible speed, manufacturer, and so on. d...
As for the Bulgarian disks are not interchangeable, then use them for other purposes can lead to tragic consequences. So, if you cut the concrete disc for metal, that is a strong likelihood that the disc shatter and injure the worker.
Therefore, setting out the disk image and the ring is not only convenient but also more secure manner.
