MILLING METHOD BY ADAPTABLE TOOL Russian patent published in 2006 - IPC B23C3/02 

FIELD: machine engineering, working profiles of rolling surfaces of wheel pair of railway road transport vehicles.

SUBSTANCE: method comprises steps of imparting rotation and feed motion along worked surface to blank and to milling cutter in body of which cutters having round cutting tips of hard alloy are mounted. In order to enhance efficiency and quality of working milling cutter is provided with damping member in the form of washer like corrugated spring. Body of milling cutter has trapezoidal radial grooves enlarged to axis of milling cutter and designed for placing said cutters with cutting tips of hard alloy engaged with damping member. Surfaces of radial grooves are faced with bronze porous self-lubricating plates. All said plates except one lateral plate are plane-parallel and they are fixed to body. Said lateral plate is in the form of wedge and it is designed for adjusting gap between it and cutter with use of screw. Cutters in the form of trapezium reciprocal to radial groove of milling cutter body are mounted in said grooves by sliding fit and they are hold in grooves by means of first lid at one end and by means of damping member and second lid at other end. Lids are secured to body by means of screws designed for adjusting elasticity of damping member.

EFFECT: enhanced operational reliability, increased vibration resistance of milling cutter.
