Title:
MACHINE TOOL FOR POLISHING FLAT ARTICLES
Document Type and Number:
WIPO Patent Application WO/2001/036152
Kind Code:
A1
Abstract:
A machine tool for polishing flat articles comprises a bed (1) with two vertical columns (C2) and a table (3) arranged between (C2) has a rotating faceplate (P4) that is provided with a plate (5) with vacuum holders (6). The machine tool also comprises two autonomously controlled spindles (S11) for polishing wheels (14). The (S11) are mounted in such a way that they are capable of reciprocal motion across a surface of the article being machined. The machine tool is also provided with a crossbeam (7) which is rigidly connected to the vertical column (C2). Each (S11) is cinematically connected with the crossbeam (7) by means of an axle (8) arranged in therein in such a way as to enable reciprocal motion, and by means of an arm (9) which is mounted on the axle (8) in such a way as to enable limited turning together with the (S11), along the surface being machined. Each (S11) is mounted in the area of the free end of the corresponding arm (9) in such a way as to be able to perform an alternate micro-motion across the surface being machined by means of an autonomous drive of the micro-motion. The drive is adaptively connected to a sensor used for the active control of the surface being machined. The plate (5) with the eccentrically embedded holders (6) is used for basing and fixing the articles being machined.
