A tool is rotated by a spindle mounted on a Z-axis table carried on a column and moved in the direction of a Z-axis to process a workpiece, while moving an X-axis table supported on a column rising from a bed in the direction of an X-axis and moving a Y-axis table supported on the X-axis table in the direction of a Y-axis to move the workpiece supported on the Y-axis. By controlling the movement of the X-axis and Y-axis tables in a contouring manner to move the workpiece along any path, holes having various sizes and shapes can be made by one type of the tool. Moreover, the wear of a cutting blade of the tool can be compensated by correcting the path of movement of the workpiece.

Machining center, contouring process, and tool supporting mechanism

A multispindle-head machine tool has a column, a plurality of multispindle heads each having a plurality of tools and an engaging member and an annular feed passageway supporting the multispindle heads for circulatory movement therealong. The annular feed passageway includes a pair of upper and lower fixed guide members supported on the column, and a movable guide member movable back and forth horizontally for interconnecting ends of the upper and lower fixed guide members near a machining position. A rotary actuator is provided together with a feed mechanism disposed around the annular feed passageway and movable to circulate along the annular feed passageway by the rotary actuator for moving the multispindle heads along the annular feed passageway. An actuator unit is mounted on the column in association with the movable guide member for positioning one of the multispindle heads which is held on the movable guide member in the machining position, and rotating the tools of one of the multispindle heads. A jig table is mounted on a side of the column and horizontally movable back and forth. The jig table includes an attachment jig for supporting a workpiece to be machined by the tools of one of the multispindle heads.
