The polyimide resin diamond wheel is made of diamond abrasives and polyimide with high-temperature resistant and high-strength as the bonding agent.

The heat resistance performance of diamond grinding wheel has been greatly improved, and is can be used for dry and large feed rough grinding tungsten carbide. The life of polyimide resin diamond wheel is longer than that of phenolic resin bond diamond grinding wheel.

Application of Polymide In Grinding Wheels:

P84 polyimide powder is a completely imidized PI resin. Due to its chemical structure, it is a kind of infusible and non-thermoplastic polymer.

Generally speaking, compared to other polymers such as polyamide, epoxy resin, and poly ether ketone, polyimide resin has the highest thermal stability. With high thermal stability and extremely high strength, P84 polyimide is a ideal choice for high quality resin bond diamond grinding wheel.

Features of Polymide Resin Wheels：

Compared with traditional phenolic resin bond diamond grinding wheel, polyimide resin diamond wheel has high mechanical strength and impact resistance, smaller friction coefficient, and high thermal stability.

When machining the tungsten carbide blades, the sound of grinding is clear, the quality of the blade is stable, no protrusion, and the life is 2.5 times longer than that of phenolic resin bond grinding wheel.

Application of Polymide Diamond Grinding wheels:

With good thermal stability, polyimide resin bond diamond grinding wheel is suitable for rough grinding of objects with large feed, deep cutting , or high speed, such as tungsten carbide or cast iron workpieces. Due to the good rigidity of polyimide resin bond diamond grinding wheel, when high flatness is required for grinding workpieces, it is an ideal for choosing this kind of grinding wheel.

Polyimide resin diamond grinding wheels are particularly suitable for the following items.
