Abstract: A Block-Type structured diamond grinding wheel with adaptive supply of instantaneous Cooling, includes a grinding wheel substrate and several grinding wheel units, each including an execution mechanism, a push mechanism, and an instantaneous Cooling mechanism. Various structured patterns are provided on an upper surface of the grinding unit in the execution mechanism, and a heat sink is disposed at a lower surface. During operation, a tangential grinding force generated by the grinding unit and a workpiece presses a sprayer to spray nano fluid into an operating region, to implement instantaneous Cooling of grinding wheel. When wear occurs in a grinding unit of a grinding wheel, a corresponding grinding unit may be replaced to extend the service life of the grinding wheel, and production costs are reduced. A special surface structure of the grinding unit further enhances a cooling effect, thereby improving a surface quality of a workpiece.
