Abstract
This dressing device has: a gear grinding tool spindle () that rotatably supports a screw-shaped grindstone (); and a dressing tool () that dresses the screw-shaped grindstone (). The dressing device dresses the screw-shaped grindstone () by driving the screw-shaped grindstone () to rotate, and causing the relative motion of the screw-shaped grindstone () and/or the dressing tool (). The dressing device performs a dressing process on the screw-shaped grindstone () in a manner such that the pressure angle changes along the direction of the tooth line by means of moving the screw-shaped whetstone () and/or dressing tool () at a fixed speed and altering the speed of rotation of the screw-shaped grindstone (), or rotating the screw-shaped grindstone () at a fixed speed and altering the speed of motion in the axial direction of the screw-shaped grindstone () and/or the dressing tool ().
