PURPOSE:To make the pentahedral machining of a workpiece performable in an easy manner, by constituting a tool chuck with five spindles of a vertical Z'-axis chuck, horizontal Y-Y'-axis chucks and horizontal X-X'-axis chucks in total. CONSTITUTION:A vertical upper Z-axis of an almost hexahedral tool block 1 is a setting axis 2 to be set to a spindle of a machine tool. A vertical Z'-axis chuck exists in a vertical Z'-axis in the opposite direction, and in four directions of the horizontal direction, there are provided with an X-axis chuck 4, an X'-axis chuck 5, a Y-axis chuck 6 and a Y'-axis chuck 7, respectively. The spindle setting axis 2 and a Z'-axis chuck 3 both consist of one axis in succession. The spindle bevel gear 8 installed in this axis and the chuck axis bevel gear 9 installed in each chuck axis in the horizontal four directions are engaged with each other, thus they are rotated together with all five spindles. |
