Last time for the damage of [u]180*6*22mm metal grinding disc[/u], three preventive measures were proposed. This time we continue the last topic.
 
4. Installation
If [u]China high efficient grinding disc[/u] is mounted on an unsuitable instrument, such as at the end of the main shaft of the polishing machine, accidents or breakage may occur. The main shaft should have a proper diameter, but not too large, so as to prevent the center hole of the grinding disc from cracking. The flange shall be made of mild steel or similar material and shall not be less than one-third of the diameter of the grinding disc.
 
5. Speed
180*6*22mm metal grinding disc must not run faster than the maximum allowable working speed specified by the manufacturer. All grinding machines should be marked with spindle speed. The large permissible peripheral speed and corresponding speed of the new grinding disc are also displayed on the grinding disc. For variable speed grinding machines and grinding discs, special protective measures must be taken to allow the hand-held grinding machine to be installed with the appropriate permissible speed.
 
6. Operating bracket
Whenever possible, you need to provide the right size and install a solid stand. The bracket should be adjustable as close as possible to 180*6*22mm metal grinding disc to avoid leaving a gap, because in the gap, the workpiece will be pressed onto the disc, the disc bursts, and the operator's hand enters the gap and hurts.
 
7. Protection
The shroud should have sufficient strength to resist bursting of 180*6*22mm metal grinding disc. Some countries have detailed provisions on the design and use of protective devices. In general, cast iron or cast aluminum should be avoided. The grinding operation opening of the guard should be as small as possible and should be fitted with an adjustable baffle.
 
In special cases, due to the nature of the work, the protective device cannot be used and can be protected with a special protective flange or a safety chuck.
