Conditions for high-speed grinding of grinding wheels
Grinding is a machining method that uses abrasives or tools to remove excess material from a workpiece. Grinding is a mechanical processing in the field of removal processing, which belongs to the advanced processing technology category in advanced manufacturing technology. According to the linear speed of the grinding wheel, grinding can be divided into ordinary grinding (V≤45m/s), high-speed grinding (45m/s≤V≤150m/s) and ultra-high-speed grinding (V≥150m/s)
High-speed grinding is to increase Vs. It can reduce the thickness of a single abrasive chip, which can effectively reduce the roughness of the workpiece, improve the machining accuracy, improve the efficiency of the machine tool, extend the service life of the wheel, and improve the shape shape retention. . The key of achieving high-speed grinding is whether there can be higher grinding head speed, greater motor power, higher grinding machine rigidity, stronger grinding cooling system, better bearing cooling scheme, higher grinding wheel strength, and Is there an automatic wheel balancing system installed on the grinding wheel? The key to restricting high-speed grinding is the strength of the grinding wheel. The strength of the grinding wheel determines the grinding speed, which poses a great challenge to the grinding wheel technology.
