FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly, to wheel pair lathes. Mobile device is mounted on rollers (10, 10') to move on in-shop track (11) for machining wheel pairs (4, 6) arranged in rotary trucks by lathe (2). Said lathe 2 can be jointed with service container 3 also mounted on rollers (10) running on said track (11). There are also devices (7) to support unmachined wheel pair (4, 6) of rotary truck. Mobile lathe (2), service container (3) and device (7) are arranged on common bearing frame (9) mounted on roller (10) running on in-shop track (11).
EFFECT: removal of chips formed in log-term operation.
