During metal grinding process, it is very important to choose the right grinding fluid in order to obtain the ideal machining accuracy and surface quality. Different metal grinding processes have different processing phenomena and different requirements on grinding fluid, so the grinding fluid used is more different.

For high precision CNC cylindrical peel grinding machine, widely used for profile cylindrical peel grionding former working procedure of milling cutter, drill bit, tapping, non – standard carbide rotary tools .

Centerless grinding is on centerless grinding machine, which interacts with regulating wheel and supporting plate to grind workpiece cylinder. During grinding process, no spindle or fixture is used to locate and secure the workpiece, workpiece is between the grinding wheel and the regulating wheel, supported by the support plate below, and the regulating wheel drives the cylindrical workpiece to rotate on the pad iron. Centerless grinding can also be used for inner circle grinding. During machining, the outer circle of the workpiece is supported on the roller or the supporting block, and the workpiece is driven to rotate by the eccentric electromagnetic suction ring. The grinding wheel extends into the hole for grinding. Centerless inner circular grinding is usually used to grind inner groove of bearing ring on special grinding machine for bearing ring.

CBN grinding wheel has high hardness and wear resistance, and the material removal rate of CBN grinding wheel is higher than that of ordinary grinding wheel. 

In the grinding process, under the action of friction and extrusion, the edges and corners of the grinding wheel gradually become round and blunt, or in the grinding of tough materials, the grinding debris is often embedded in the pore of the grinding wheel surface, so that the surface of the grinding wheel is blocked, and finally the grinding wheel loses its cutting ability.

CBN internal grinding wheel for grinding hole requires the machine to have enough rigidity and the grinding wheel to keep enough stable state, otherwise it is easy to produce grinding vibration veins, especially for processing thin-walled disc parts with inner holes.
