An apparatus (100) for cutting workpieces (1) adapted to engage the workpiece (1) in at least four points of surface engagement. The apparatus (100) has a clamping mechanism (2) designed to be fastened to the workpiece (1). The clamping mechanism (2) has a tool unit (3) attached which includes adjustment means (4) for displacing the tool unit (3) relative to the clamping mechanism (2) towards or away from the workpiece (1). The clamping mechanism (2) has a frame element (5) and arms (6, 7, 24, 25) extending from the clamping mechanism (2). Each of the four arms (6, 7, 24, 25) includes a bearing wheel (15, 16, 35, 36). Each of the wheels (15, 16, 35, 36) may be used to engage a workpiece (1) to retain its position while it is being cut. |
