Cutting frame for sawing blocks of stone, rock, granite, marble or the like

摘要

A cutting machine comprises one horizontal blade-holding frame (1); one or more parallel and adjacent cutting blades (2), held by the blade-holding frame (1) for cutting one or more blocks (B); means (4, 30, 31, 201) for guiding and supporting the blade-holding frame (1), for alternatively moving it in the direction of the cutting edge of the blades (2); means (3, 103, 12, 13, 14) enabling the relative motion of the blade-holding frame (1) with respect to the block(s) (B) which are being processed, and in the penetration or downfeed direction of the blades (2) through them; means (15, 16, 17) for reciprocatingly moving the blade-holding frame (1) in the direction of the cutting edge of the blades (2). The cutting machine further comprises means (4, 104, 204, 8, 9, 10, 11) for setting the blade-holding frame (1) into a reciprocating, oscillatory and swinging movement in the downfeed direction of the cutting blades (2).
