Resinoid-bonded wheel

Resinoid-bonded wheels find wide use in heavy-duty snagging operations where large amounts of metal must be removed quickly, in cutting-off operations, portable disk grinding (as for weld-beads), roU grinding, and vertical spindle disk grinding. 

Resinoid-bonded wheels can be made extremely thin, can be used with safety at high speeds, and are ideal as cut-off wheels for cutting metal bars, tubes, etc. This type of bond is designated by the letter B. 

Rubber. Both natural and synthetic rubber are used as bonding agents for abrasive wheels. Rubber-bond wheels are ideal for thin cut-off and slicing wheels and centerless grinding feed wheels. They are more flexible and more water-resistant than resinoid wheels. 

Since fimax is solely a geometric factor, there might be concerns that thermal effects could also be a controlling factor. It should be observed that test condition number 1 is operating at near the maximum safe wheel speed for the resinoid-bonded grinding wheel employed in this research.

There are two main types of bonding agent inorganic and organic. Inorganic bonds are mainly vitrified, i.e. the wheel is generally fired in a furnace. Organic bonds are not fired, but are cirred at a low temperature, commonly resinoid and rubber.
