METHOD FOR RESTORING WORKING SURFACES OF COMPLEX-PROFILE CUTTING MEMBERS OF BUILTUP SHAPED MILLING CUTTERS FOR MILLING WHEEL PAIRS Russian patent published in 1999 - IPC

FIELD: restoration of working surfaces of complex profile cutting members of builtup shaped milling cutters for milling wheel pairs of railway road transport vehicle. SUBSTANCE: method comprises steps of subjecting cutting members of damaged milling cutters to welding by additive metal after their preliminary preparation; initially fusing inner surfaces of mounting seats for cutting tips; filling seats with technological inserts of material having no adhesion with fused metal; welding bridges between seats and front surface of cutting member; further working welded surfaces of cutting members mounted in body of milling cutter; forming necessary shaped profile and sizing mounting seats for cutting tips. EFFECT: possibility of multiple restoration of shaped milling cutters without use of expensive equipment, possibility of repairing milling cutters directly in place of their operation. 2 dwg
