Title:
METHOD FOR PRECISION TWO-SIDED MACHINING OF FLAT ARTICLES
Document Type and Number:
WIPO Patent Application WO/2001/036154
Kind Code:
A1
Abstract:
A method for precision two-sided machining of flat articles consisting in the following: a workpiece which is based at least on three points is introduced into a machining area between oppositely situated cutting elements of diamond tools (1) and (2) in such a way that all plane surfaces of the piece can be machined. Diamond drums are used as diamond tools. The generatrixes of the diamond drums are longer than the maximum length of the workpiece measured along said generatrixes. Axes (7) of rotation of the drums are oriented parallel to each other in such a way that they lie on the same plane as the contact lines between the cutting parts of the drums and the working surfaces of the workpiece. When the workpiece is introduced into the machining area, the drums perform a relative displacement such that a projection of the workpiece on the plane which is perpendicular to the axes (7) of rotation of the drums performs a forward motion across the axes of rotation. Said axes (7) are allowed to intersect the axis (8) of rotation of the workpiece during a complete machining cycle. The base positioning of the workpiece is carried out along the contact line between one of the surfaces being machined with the cutting element of the corresponding diamond drum and with aid of at least one base device which is situated outside the cutting area.
