<p>This invention relates to a superfinishing machine with a lapping film (25) which is used for superfinishing the surface (30a) to be finished of a work (30) which is either rotated or reciprocated. The rotating direction of a pair of take-up rollers (2, 3) for taking up the lapping film is switched and controlled by driving switching means (23, 24) and at the same time, a follower friction wheel (8, 9) to be driven is braked by braking means (26). Accordingly, the entire abrasive surface of the lapping film (25) can be utilized effectively and excessive pull-out of the lapping film (25) can be prevented effectively. Since the machine is equipped with press means (29) for pressing the lapping film (25) to the surface (30a) to be polished of the work (30), high precision polish faithful to the contour of the surface (30a) to be polished can be attained.</p> |
