Abstract

See full text

A vertical machining center includes a table, a tool spindle, an angle tool holder, a tool unclamping operation device, and a tool changer. The angle tool holder includes a shank, a spindle, a housing, a collet, a draw bar, and a spring mechanism. The shank has a shank axis and is rotatable around the shank axis. The spindle has a spindle axis perpendicular to the shank axis and is rotatable around the spindle axis. The tool unclamping operation device includes an angle tool holder rest, a hydraulic piston, and a restrictor. The angle tool holder is to be placed on the angle tool holder rest. The restrictor is disposed on the angle tool holder rest to restrict a portion of the angle tool holder and to receive force in a direction of the spindle axis which is generated in a case where the hydraulic piston presses the draw bar.
