[0002] When the existing grinding machine is CNC grinding roll workpieces, since the roll workpieces are convex or concave shafts with circular arcs, the grinding head and grinding wheel of the grinding machine will not only feed radially and move axially, but also with the grinding position. The change requires a rotation, and when the grinding head rotates, the position of radial feed and axial movement will change. If a qualified roll needs to be ground, the centerline of the radial and axial axes must follow the rotation axis of the grinding head. To offset the position change of the two feed axes in the radial and axial directions of the grinding wheel due to the movement of the rotating shaft, this will make the NC programming complicated and the grinding process more difficult

Embodiment Construction
[0007] A numerical control grinding method for roll workpieces. The specific method is: A. installing an axial feed guide rail and a radial feed guide rail on the horizontal surface of the grinding machine; B. setting a turntable on the radial feed guide rail, and the center line of the turntable is Perpendicular to the horizontal plane, there is a grinding wheel feed guide rail on the turntable, and there is a grinding wheel dressing guide perpendicular to it. The roller or diamond dressing pen for grinding wheel dressing is installed on the grinding wheel dressing guide rail. The feeding guide rail of the grinding wheel frame and the grinding wheel dressing guide rail are controlled by the numerical control system; C. Dress the grinding wheel into the desired shape, and control the feeding guide rail of the grinding wheel frame after dressing the grinding wheel , move the grinding wheel to the intersection of the busbar at the tangent position between the grinding wheel and t...

A roller working piece digital control grinding method features in the axial feeding guide track and the radial feeding guide track on the horizontal surface of the grinder, a rotating plate on the radial feeding guide track, center of the rotation disk vertical to the horizontal surface, an abrasion wheeler feeding guide track and the abrasion wheel finish guide track vertical to it on the rotation plate on the horizontal surface. Moving the abrasion wheel to the cross location of the bus and rotation plate center line tangential with the working piece and the cross point of the bus and the rotating center line being the grinding point, the rotation plate rotated by the digital control, controlling the running track of the grinding point being consistent with the working piece to be machined. It is simple in digital programming, convenient in operation, with high precision in grinding.
