    摘要： Provided is a method for manufacturing a hollow engine valve, by which a hollow engine valve having a shaft part with a desired thickness can be relatively easily manufactured. A method for manufacturing a hollow engine valve having a hollow part formed over a range from a shaft part to an enlarged diameter section of a valve umbrella part is provided with: a rotational plastic working step for performing rotational plastic working on a follow engine valve body semifinished product (10) which is configured from a shaft part (11) and a valve umbrella part forming portion (12) connected to the shaft part, and in which a columnar hole part (13) is formed over a range from the shaft part to an enlarged diameter section of the valve umbrella part forming portion to thereby reduce the diameter of the shaft part; a necking step for, following the rotational plastic working step, necking the hollow engine valve body semifinished product to thereby reduce the outer diameter and the inner diameter of the shaft part; and a sealing step for, following the necking step, sealing the leading end of the shaft part to obtain the hollow engine valve.

    摘要： Work line module comprises a plurality of machines (103-106) having a plurality of working functions and non-work facility (107, 108) such as a conveying machine can cooperate so as to produce a necessary amount even if the necessary amount is varied. A plurality of work machines (103-106) for mechanically working a workpiece (124) and non-work facility (107, 108) for processing the workpiece (124). One work machine (106) is a multifunction furnishing machine having a function of measuring the workpiece (124) in addition to a function of mechanically working the workpiece (124). A conveying machine (109) having robots (185-187) for conveying the workpiece (124) between the work machines (103-106), and between the work machines (103-106) and the non-work facility (107, 108).
