Product Details

Diamond grinding wheels for sharpening tungsten carbide circular saw blades in Woodworking industry. Widely used for face grinding, top grinding, flank grinding, hollow tooth grinding and re-sharpening for tungsten carbide tipped saw blades and one-piece HSS saws.
What type of grinding wheels for sharpening saw blades

Resin bond diamond grinding wheel. The bond strength is weaker than other wheels. The self-sharpening for carbide saw blade is better. The low grinding force and grinding temperature . Wear resistance is poor, and the wear of abrasive tools is high and is not suitable for heavy load grinding. Resin bond diamond grinding wheels are used for sharpening carbide saw blades. Resin CBN wheels for hss circular saw tipped.

 

Vitrified bond diamond grinding wheels. Vitrified diamond wheels for grinding pcd tips saw blades. The wear resistance and bonding strength is higher, and the cutting is sharper and efficiency is higher. It has better control for heating, blocking, thermal expansion and accuracy. But the surface of saw blade after sharpening is rough and the cost is higher.
