Method and apparatus for internal grinding and outer surface grinding machine parts rotationally symmetric with a longitudinal bore

摘要

Machine parts (5) has a working surface of the conical. Machine bed (1), in the longitudinal direction movable grinding table (7), the one above it work headstock that sandwich mechanical parts (5) clamping jaws (4) chuck (3) (2) apparatus including the door is used in the processing. By be longitudinally displaced in the direction longitudinal axis (6) and (7) grinding table, working surface of the cone-shaped mechanical part (5) is ground in a vertical spindle grinding method (14) the first grinding wheel. Grinding headstock supplied with (10), in addition grinding spindle of the first for (14) the first grinding wheel (12), the second grinding wheel attached to (15) the grinding arbor (16) also has (13) the grinding spindle of the second for. Mounted grinding headstock saddle (9) grinding headstock (10) to pivotally about a vertical axis (11), the grinding headstock saddle X axis through (8) adjusting motor It can be moved in the direction of. The sign B, represents the turning direction of the grinding headstock (10), Z and X are the usual axes of CNC control technology. Be allowed to act in (5) mechanical parts (16) the second grinding wheel in order to move it to exit out of the area of ​​the mechanical parts the first grinding wheel (14), and internal grinding a longitudinal bore that it can be is obvious.
