FIELD: machine building.

SUBSTANCE: device comprises a bracket attached to a container and including a plate with an inner boring made along a trunnion diameter, and set on the non-machined section of the trunnion. A support with a hole whose axis coincides with the trunnion axis is attached to the plate. An axle is installed in the support hole, a casing able of swinging is mounted on the axle and connected to a cross bar to which U-shaped swinging levers connected by rams in the lower part are coupled. The rams are movably fitted with a screw cross-feed mechanism with a pneumatic grinding machine being attached to its quill. The screw cross-feed mechanism is coupled with a quill of a screw longitudinal feed mechanism of the grinding machine placed inside a handle attached to the swinging lever. A grinding disk or a rolling disk is installed on the grinding machine shaft.
