BAR-LIKE WORK PROCESSING METHOD IN MACHINE TOOL, PROCESSING JIG FOR PERFORMING THE METHOD, AND SUPPORT DEVICE FOR BAR-LIKE WORK PROCESSING

摘要

A main shaft ( 6 ) movable in a direction of X-axis is provided at a position on one side of a foundation ( 1 ), and a lateral stand ( 12 ) is fixed on the top portion of the rotation support shaft ( 10 ). On the upper surface of the lateral stand ( 12 ), there is provided a work grip rotation feed mechanism portion ( 13 ) for rotating bar-like work (w) about a specific lateral axis (S) on the upper surface. The rotation support shaft ( 10 ) and the specific lateral axis (S) are horizontally separated by a required distance (L 0 ). The rotational position of the rotation support shaft ( 10 ) is varied between the case where the bar-like work (w) is processed by the operation of the main shaft ( 6 ).
