Claim:
A machining center for machining a workpiece on a table, comprising: a spindle being movable in a Y-axis direction and in a Z-axis direction with respect to a main unit, and being immovable in a X-axis direction, said X-, Y-, and Z-axis directions being substantially perpendicular to one another, said Z-axis direction extending in the direction of a longitudinal axis of the spindle, and said spindle having a tool mounting portion on its end; a turn table located on a front side of said main unit, said turn table having a horizontal workpiece mounting face which rotates only in a C-axis direction, said turn table having a rotation axis that is immovable in the X-axis direction; an automatic tool changer located on the rear side of said turn table on said main unit side, having a tool change position on a Y-Z plane; and a separated control panel independently formed from said main unit, said separated control panel located on a rear side of said automatic tool changer; characterized in that machining is executed on a workpiece on said workpiece mounting face by rotation of said turn table in said C-axis direction and movement of said spindle in said Y-axis direction and in Z-axis direction, and a tool is exchanged between said spindle and said automatic tool changer by relative movement between said spindle and said automatic tool changer in said Y-axis direction and in said Z-axis direction.
