METHOD OF PRODUCTION OF PARTS WITH KEY SLOT

摘要

FIELD: mechanics. ^ SUBSTANCE: proposed method comprises fabricating part, producing key slot followed by electric-contact processing and heating. Prior to processing, tool roller is produced with its diameter equal to that of the part. Contact surfaces of the part and tool roller key slots are aligned to bring them into contact. Electric-contact processing is carried out by rolling the tool roller on over the part diametral surface. ^ EFFECT: higher quality of machine parts in producing key slots of outer and inner surfaces. ^ 1 dwg, 2 ex
