MACHINE TOOL TO MACHINE AUTOMATIC COUPLER CASING Russian patent published in 2010 - IPC B23C3/00 B23C1/12 

FIELD: process engineering.

SUBSTANCE: invention relates to machine building, particularly to machine tool that allows machining automatic coupler casing surfaces. Machine tool comprises two lengthwise and crosswise tables mounted on the bed to move perpendicular to each other in horizontal plane, and rotary table with the support that supports rotary spindle head with cutter to machine coupler tail part end face. Crosswise table accommodates the support to carry lower spindle head with cutters to machine larger tooth impact and draw surface. Upper spindle head with cutters to machine impact and draw surfaces is mounted on aforesaid port. Upper spindle head axis is located in the plane parallel to lifter roll bore axis. Lower spindle head axis is arranged at an angle to upper spindle axis, while rotary spindle head is arranged to turn through radius equal to the sum of coupler tail part and face machining cutter radii.

EFFECT: higher precision and reduced time of milling.
