INTERNAL GEAR GRINDING MACHINE |
摘要 |
An object is to provide an internal gear grinding machine which makes it possible to achieve space savings and reduce the size of a machine, as well as to prevent the tools from being damaged even when an abnormal situation such as a blackout occurs, by simplifying dressing operation. To achieve the object, an internal gear grinding machine for use in grinding a workpiece (W) by synchronously rotating the workpiece (W) and a barrel-shaped threaded grinding wheel (17) in mesh with each other includes a dressing device (20) for dressing the threaded tool (17) by meshing the threaded grinding wheel (17) with a disk dresser (56). At the time of dressing, the threaded grinding wheel (17) and the disc dresser (56) are operated in accordance with the helix angle and barrel shape of the threaded grinding wheel (17), and the brake mechanism (58) applies a braking force to a dresser turn drive motor (53) to enable the disc dresser (56) to be maintained at a turned position thereof. |
