Abstract
A grinding machine includes a main spindle on which a grinding wheel is mounted, a spindle head movable relative to a workpiece, a dressing device body provided to be movable relative to the spindle head and a dresser supporting member provided to be movable relative to the dressing device body for rotatably supporting a dresser. The dressing device body is moved to a dressing position while the grinding machine grinds with continuous dressing. The dressing device body is moved to a retracted position while the grinding machine normally grinds except for the grinding with continuous dressing.
Claims22
A grinding machine comprising:
- a main spindle on which a grinding wheel for grinding a workpiece is detachably mounted;
- a spindle head for rotatably supporting said main spindle, said spindle head being movable relative to the workpiece along at least three mutually transverse axes including a direction in parallel with an axis of said main spindle;
- a dressing device body provided to be movable relative to said spindle head along at least one direction perpendicular to the axis of said main spindle;
- and
- a dresser supporting member provided to be movable relative to said dressing device body along one direction perpendicular to the axis of said main spindle, said dresser supporting member rotatably supporting at least one dresser for dressing said grinding wheel,
- wherein said dressing device body is moved to at least one dressing position in which said dresser dresses said grinding wheel, while said grinding machine grinds with continuous dressing in which an operation of dressing said grinding wheel with said dresser and an operation of grinding the workpiece with said grinding wheel are performed simultaneously;
- and
- wherein said dressing device body is moved to at least one retracted position at which the workpiece does not interfere with at least said dresser, while said grinding machine normally grinds except for said grinding with continuous dressing.
