Green silicon carbide contains at least 97% SiC. It is harder than black variety and is used for grinding cemented carbide. Diamond Diamond grit is best suited for grinding cemented carbides, glass, sapphire, stone, granite, marble, concrete, oxide, non-oxide ceramic, fiber reinforced plastics, ferrite, graphite.
How often should abrasive wheel training be given?
From what I can find Red, the general consensus is that PUWER says the training should be “adequate”, meaning if someone hasn’t been doing the changing for some time, (frequency) then re-training would be advisable, however, if the person has been on-going doing the changing of the abrasive wheel, then 3 to 5 years …
What type of abrasive wheel is used on a hand held disc cutter?
An abrasive wheel is a wheel, cup or cone consisting of abrasive particles bonded together with various substances. There are two main types of bonding agent, inorganic and organic. Only organic-bonded wheels should be used for portable and hand-held grinding machines.
