MACHINE FOR ABRASIVE TAPE GRINDING AND POLISHING OF ELONGATE CYLINDRICAL ARTICLES Russian patent published in 1996 - IPC

FIELD: mechanical engineering, in particular, grinding and polishing of bars and pipes with abrasive tapes. SUBSTANCE: machine has frame, tape-feeding mechanism mounted on frame, article receiving device pivotally connected with tape-feeding mechanism. Each mechanism has friction disk connected to bracket for displacement relative to it. Bracket is mounted on frame for rotation relative to axis intersecting axes of rotation of article and friction disk and disposed in plane coinciding with disk plane. Base device mounted on frame has two guides with calibrating nozzles fixed on its ends. Guiding base devices and receiving and feeding mechanisms are positioned in symmetry with respect to tape rotation plane. Tape-feeding mechanism is further provided with deflecting roller for moving away and bringing tape into contact with article. EFFECT: increased efficiency, simplified construction and improved quality of worked surface. 2 cl, 3 dwg
