Abstract: An apparatus (100) for cutting workpieces comprises a clamping mechanism (2) adapted to be fastened to said workpiece (1) rotatably therearound. The clamping mechanism (2) comprises a frame element (5) and first and second arms (6, 7) extending therefrom. The arms (6, 7) are coupled at one end to the frame element (5) of the clamping mechanism (2) and each arm (6, 7) has its free end fitted with a contacting member (15, 16, 31, 32) configured to contact the surface of the workpiece. The apparatus comprises also two movable guiding members (28, 29) to which said arms (6, 7) are coupled so that when said guiding members (28, 29) are moved away from each other, the contacting member (15, 16, 31, 32) of the arms (6, 7) are configured to be moved away from each other and vice versa. The apparatus comprises also at least two supporting bars (50, 51) elongated through said guiding members (28, 29). The first supporting bar (50) comprises a first threaded portion (52) with a first coupling means (21), and the second supporting bar (51) comprising a second threaded portion (53) with a second coupling means (22). The first arm (6) and the first coupling means (21) are functionally coupled to each other by a first suspension arm (24), and the second arm (7) and the second coupling means (22) are functionally coupled to each other by a second suspension arm (25). The supporting bars are configured to be rotated at the same time.

Abstract: An apparatus for cutting workpieces adapted to engage the workpiece in at least four points of surface engagement. The apparatus has a clamping mechanism designed to be fastened to the workpiece. The clamping mechanism has a tool unit attached which includes adjustment elements for displacing the tool unit relative to the clamping mechanism towards or away from the workpiece. The clamping mechanism has a frame element and arms extending from the clamping mechanism. Each of the four arms includes a bearing wheel. Each of the wheels may be used to engage a workpiece to retain its position while it is being cut.

Abstract translation: 一种用于切割适于在至少四个表面接合点接合工件的工件的设备。 该装置具有设计成紧固在工件上的夹持机构。 夹紧机构具有附接的工具单元，其包括用于相对于夹紧机构朝向或远离工件移动工具单元的调节元件。 夹紧机构具有框架元件和从夹紧机构延伸的臂。 四个臂中的每一个包括一个轴承轮。 每个轮可以用于接合工件以在其被切割时保持其位置。
