Grinding wheel, grinding wheel unit and machine tool

摘要

Problem to be solved: to provide a grinding wheel, a grinding wheel unit and a machine tool capable of increasing the machining amount while suppressing the lowering of the machining ability.The grinding stone 10 for processing the workpiece W is arranged along the circumferential direction C of the grindstone 10 to the side surface 41 of the grindstone 10, and has a plurality of columns 42 extending in the direction intersecting the side surface 41 of the grindstone 10.The column portion 42 includes a plurality of abrasive grains contacting the workpiece W when the work W is to be machined, and a coupling material for coupling a plurality of abrasive grains.Thus, the machining amount can be increased while suppressing the lowering of the machining ability of the grindstone 10.Diagram
