    摘要： A first grinding head is provided on a base frame 10 via a first movable body 11A and a first grinding base 12A. The proximal portion of the tilt arm 28 is tiltably fitted in the housing of the grinding head. A measuring device 41 is rotatably coupled to a distal portion of the tilt arm 28. A gauge 46 and a measuring pin 47 are coupled to the lower end of the measuring device 41, and the gauge 46 is engaged with a crankpin 23a of a crankshaft A tilt center 028 of the tilt arm 28 is arranged on the same axis as the rotation center O15 of the first grindstone 15A. When the tilt arm 28 is tilted, the position of the measuring device 41 is changed, accordingly, However, since the relational relationship between the first grindstone 15A and the gauge 46 is not changed, the position of the gauge 46 is easily adjusted in accordance with the diameter of the crankpin 23a. Accordingly, a grinding machine is provided that simplifies the movement path of the gauge of the measuring device, thereby allowing the outer diameter of the workpiece to be quickly measured.

    摘要： A grinding machine includes a pair of workpiece support devices (12, 13), which clamp and rotate a workpiece (W), on a bed (11). A pair of saddles (14) is provided on the bed (11) in such a way as to be movable along the rotational axis of the workpiece (W). Grindstone heads (16) provided with rotating grindstones (16c) and drive mechanisms (16d) are supported on the saddles (14) in such a way as to be movable in a direction that perpendicularly intersects the movement direction of the saddles (14). There is provided a partition structure (20) which consists of a fixed cover (21) and a extendable cover (22), and serves to partition a machining region (T) for the purpose of sealing off the same so that the clamping portions (12a, 13a) and the rotating grindstones (16c) of both of the workpiece support devices (12, 13) will be located inside the machining region (T), and that bearing sections (12b, 13b) and driving sections (12c, 13c) of both of the workpiece support devices (12, 13), as well as bearing sections (16b) and driving sections (16d) of both of the grindstone heads (16), will be located outside the machining region (T).
