Abstract
PURPOSE: To provide high-precision grinding of the rear portion of a stepped work with an optical profile grinder, by setting the work vertically and projecting the profile of its stepped portion on a screen through a movable mirror in the below.
CONSTITUTION: A work 1 is so set that its stepped portion is positioned vertically. A movable mirror 5 mounted below the work 1 directly receives light from a reflecting illuminator 3 and reflects it for projecting the profile of the work's stepped portion on a screen 6. A grindstone 2 then efficiently provides high-precision grinding on the base of this projection. Since some work 1 with a large or complicated step is not always clearly projected on the screen 6 due to the influence of the depth of focus, another movable mirror 8 is mounted below the work 1 to catch the profile of the stepped portion and project its expanded shape through reflection on the screen 6.
