"Grinding Instructions:

If the material gets too hot during the grinding process, drawing threads or forming knots on the surface, the feed should be stopped.Grinding should then be continued without tool feed until the surface is restored.Where possible however the disk should be skimmed clear of 'built-up' or melted spots with diamond-felt, before restarting the tool feed, slightly reducing the feed if necessary."
