PROBLEM TO BE SOLVED: To provide a workpiece machining device capable of efficiently machining a disc rotor to predetermined precision. SOLUTION: This workpiece machining device 10 is provided with a rotary mechanism 11 for rotating a hub 3 of a hub assembly 1 with disc and the disc rotor 6 integrally, tools 40, 41 for grinding rotating disc rotor 6, and a measuring device 45 for measuring surfaces 6a, 6b of the disc rotor 6 after machining. A partitioning member 50 is provided between a face to be machined (surface 6a) of the disc rotor 6 and a bearing part 9. An air introduction port 55 is opened in a space S on an inner side of the partitioning member 50. High pressure air fed from a compressed air supply source 32 is supplied into the space S on the inner side through the air introduction port 55. It is possible to suppress the adhesion of chips generated when machining the disc rotor 6 by the tools 40, 41 to the bearing part 9 by high pressure air blown out to the outside from the space S on the inner side.
