Background
After the formed blank of the vitrified tile is fired, the surface smoothness can not meet the application requirement of the vitrified tile; large size tiles tend to warp, twist, warp to different degrees, and require edging, chamfering, flat grinding, and polishing. Grinding is a leveling and thickness-fixing process for the vitrified tiles to facilitate surface grinding and polishing. The polishing is to grind, polish, chamfer and chamfer the surface of the ceramic brick or board by utilizing the high-speed rotation of various tool bits of a polishing machine, so that the use surface of the ceramic brick or board is smooth and bright like a mirror.
The grinding tool for polishing the vitrified tiles is called a cutter head. The cutter head is a key tool in the polishing process of the vitrified tile. The tool bit is made of abrasive and bonding agent, and the abrasive such as diamond, cubic boron nitride, corundum, silicon carbide and the like is adhered to a metal matrix by using metal bonding agent, ceramic or resin or is made into tool bits with various shapes and sizes by adopting an electroplating method.
When the abrasive particles are dull ground, the abrasive particles partially or completely fall off from the grinding tool due to the self-fragmentation of the abrasive particles or the fracture of the bonding agent, and a new cutting edge or a new sharp abrasive particle is continuously exposed on the abrasive material on the working surface of the tool bit, so that the tool bit can keep the grinding performance for a certain time. The self-sharpening property of the cutter head is the prominent characteristic of the cutter head different from a common cutter.
