PROFILED MILLING METHOD Russian patent published in 2006 - IPC B23C3/04 

FIELD: metal working, in particular, working of rolling surface profile of wheel pairs for railway transport.

SUBSTANCE: method involves transmitting rotational motion and feeding motion to profile cutter mounted on holder and to blank; using cutter located on mandrel for rotation in slider bearings formed as bushings and in thrust roller bearings. One end of cutter is made corrugated for joining to mated corrugated end of coupling mounted on mandrel in slots for axial displacement and biased by nut to cutter with the help of damping member formed as disk spring. Other end of cutter is biased with the help of nut through one of thrust roller bearings. Before machining, resiliency of damping member may be regulated for increasing resistance to vibration, providing continuous-intermittent bringing into contact and separation of cutter teeth from contact with surface under machining process, said surface having thermomechanical and other defects.

EFFECT: increased durability, enhanced reliability in operation and increased efficiency.
