What are metal bond grinding wheels and what benefits do they offer?

Metal bond grinding wheels, a staple in diamond grinding wheel manufacturing, are crafted through three distinct processes: cold press, semi hot press, and hot press modes.

Advantages of Metal Bond Grinding Wheels

Each superabrasive grinding wheel comprises diamond or CBN grit enclosed within a supporting matrix referred to as the "bond." The primary bonding systems include resin, vitrified, plated, and metal. Among these, metal bond grinding wheels stand out due to their overall versatility and extensive availability.
