Resin bonds have been used for superabrasive wheels for many years. They are probably the most common type of bond material for superabrasives. They are relatively easy to manufacture and therefore relatively inexpensive. Resin bond wheels are used extensively for plain profile operations.
We offer two families of resin bonds, phenolic and polyimide resins.
Phenolic resins have gained a reputation as good general-purpose wheels for grinding parts with simple forms. It wears relatively fast. So if you make mistake during the grinding, you just let the wheel wear little. Resin bonds wheel also absorb a fair amount of impact. Consequently, resin bonds are less than careful handling and a little variation process that are not controlled as tightly as they should be. Other reason for the popularity of resin bonds in general-purpose wheels include their ability to run either wet or dry and to work on low-power surface grinders that cut at slow surface speeds. Although they carry the second-lowest price tag (after electroplated wheels) of all the bonds, they require separate truing and dressing operation. Moreover, the heat generated in grinding degrades phenolic resins, causing the wheels to grow dull rapidly and need refurbishing or replacing frequently.
Polyimide resins, on the other hand, are stronger than their phenolic counterparts. In fact formulators can alter their chemistry to make them tough, brittle, ductile, abrasion, resistant, heat conducting, and formable as necessary, marking these resins the most versatile of the superabrasive bonds.

Advantage:

    • Cheaper price & most wide range of application
    • Higher grinding efficiency
    • Useful for both dry & wet grinding
    • Better surface

Disadvantages:

    • Difficult to put a complicate profile into a resin bond. For this reason application normally restricted to plain profiles or a simple radius shape.
    • Truing techniques are slow and often require a subsequent conditioning process to remove bond and exposed the grits.
    • Can be affected by the heat generated in the grinding zone and for this reason wheel wear is comparatively fast.
