  • Apparatus and method for manufacturing spark plug
    Patent number: 9748742
    Abstract: An apparatus for manufacturing a spark plug by working of a workpiece with dies, wherein the workpiece has a metal shell part to be processed into a metal shell of the spark plug and a ground electrode part to be processed into a ground electrode of the spark plug. In the manufacturing apparatus, a position of the ground electrode part is measured in a non-contact manner by a position measurement unit in a state where the workpiece is held in position by a holding unit. The dies are controlled by a die control unit so as to adjust the working phase of the dies relative to the workpiece based on the measured position of the ground electrode part and then effect working of the workpiece with the dies.
