Descriptions of diamond grinding wheel for sharpening tungsten carbide saw blade
Circular saw blades with tungsten carbide (TC) segments are nowadays commonly used across various industries. Be it during production of a new saw blade, or during a resharpening of a used saw, grinding of the TC segments is a multi-step process and is performed on different machines. Moresuperhard provides diamond and CBN grinding wheels to the saw blade 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.

What are steps in the process of sharpening circular saw blades

• Flank grinding
• Top grinding
• Face grinding
• Hollow tooth grinding and resharpening

Shape and dimensions of the grinding wheels that are used in grinding carbide-tipped saw blades depend on the grinding machine, as well as on the shape of the saw blade itself.

The CNC machines:  Vollmer, Woodtronic, Akemat, Widma and so on
