Abstract
A grinding machine includes a wheel spindle stock in which a wheel spindle is rotatably provided. The wheel spindle moves between first and second spindles so that a third rotation axis of the wheel spindle moves in the direction perpendicular to first and second rotation axes on an XZ plane extending through the first and second rotation axes. The grinding wheel that is held by the wheel spindle grinds a first workpiece as the wheel spindle stock moves toward a first headstock, and grinds a second workpiece as the wheel spindle stock moves toward a second headstock.
Claims12
A grinding machine, comprising:
- a first headstock having a first spindle that can rotate about a first rotation axis extending in a vertical direction and that rotatably supports a first workpiece;
- a second headstock having a second spindle that can rotate about a second rotation axis separated from the first rotation axis at a predetermined interval and extending parallel to the first rotation axis, and that rotatably supports a second workpiece different from the first workpiece;
- a wheel spindle stock that has a third rotation axis extending parallel to the first and second rotation axes and that moves between the first and second headstocks so that the third rotation axis moves in a direction perpendicular to the first and second rotation axes on a plane extending through the first and second rotation axes;
- a wheel spindle that is rotatably provided in the wheel spindle stock;
- and
- a grinding wheel that is provided on the wheel spindle, that grinds the first workpiece as the wheel spindle stock moves toward the first headstock, and that grinds the second workpiece as the wheel spindle stock moves toward the second headstock.
