FIELD: process engineering.
SUBSTANCE: invention relates to machining device (100) and can be used for cutting, threading and/or bevelling. Claimed device comprises the frame element (102), machining assembly (104) and threading shaft (110) secured to said frame element (102) to turn thereabout and axially fixed. Said shaft consists of the first part (110a) with RH thread and second part (110b) with LH thread. The first part has at least one first bearing element (106a) while the second part has the second bearing element (106b). The distance between bearing elements can be adjusted by the revolution of threaded shaft so that said bearing elements, for example, the wheels, are brought in contact with the part at supporting and guiding the device (100) in machining. At least one of said bearing elements, for example, the wheel (106a, 106b), can run about its axis at displacement of the device over the part surface.
EFFECT: enhanced machining performances.
