Abstract

When exchanging a tool, a tool of a spindle is stored in an empty pocket of a tool magazine, and thereafter, upward movement of the spindle and rotation of the tool magazine are simultaneously executed. At this time, synchronous control is performed in order to prevent a collision between the spindle and the tool. When installing a next tool in the spindle, both downward movement of the spindle and rotation of the tool magazine are executed while synchronously controlling. The tool exchange time can be shortened with simultaneously executing the movements of the spindle and the tool magazine.

Description

technical field [0001] The present invention relates to a machining center capable of machining a workpiece while appropriately changing tools, and more specifically, to a machining center equipped with a so-called armless automatic tool changer. Background technique [0002] The machining center has a table on which a workpiece is placed, a spindle that drives a supported tool to process the workpiece, and an automatic tool changer that automatically replaces the tool on the spindle, and is configured so that the workpiece can be machined by appropriately replacing the tool. As the automatic tool changing device, there can be exemplified an ATC arm or a moving frame or an ATC arm driving unit (armed automatic tool changing device), and a tool is performed only by the movement and positioning of the tool magazine and the spindle without the ATC arm. Changing armless automatic tool changer. [0003] Compared with the arm type of the former, the latter armless type is charact...
