摘要： An apparatus (100) for machining a tubular or round-bar type piece, wherein the apparatus comprises a frame element (102), a machining unit (104), as well as a threaded shaft (110), which is fitted to the frame element in a rotatable and axially immobile fashion and has a first section 110a) provided with a right-handed thread and a second section (110b) with a left-handed thread. The first section is provided with at least one first support element (106a) and the second section is provided with at least one second support element (106b), the mutual distance between the support elements being adjustable in response to rotating the threaded shaft, such that the support elements, for example wheels, are adapted to touch a workpiece and to support and guide the apparatus (100) in the process of machining the piece. At least one of the support elements, such as wheels (106a, 106b), is adapted to be capable of rotating relative to its axis in response to moving the apparatus along the surface of a workpiece.

摘要： 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.
