Unitized Wheels and Convolute Wheels

Unitized Wheels are constructed of compressed, non-woven, tough abrasive fibers bonded together with an adhesive system under heat. The wheels are then cut from a solid block.

Convolute Wheels are constructed of non-woven nylon impregnated with abrasive grain and wrapped in layers around a core and bonded together to produce a uniform wheel.

    Other Considerations
    Softer wheels produce a rougher finish
    Lower SFPM produce a rougher finish
    Deburring requires high SFPM (6000)
    Decorative finishes require lower SFPM (900)     		Blending requires high SFPM (7000)
    S/C provides a finer (higher luster) finish than A/O
    Polishing requires a light pressure
