Description

Multi-tool changer and multi-spindle type machining center with the same Multi-tool changer and multi-

The present invention relates to a multi-machining type machining center in which a plurality of spindles are provided to machine a workpiece by a method such as cutting.

In general, machine tools are widely used for a variety of applications, including machining centers, turning centers, Swiss turn, electric discharge machines, horizontal NC boring machines, and many others.

In particular, a machining center is a machine tool for automatically machining drilling, boring, milling, cutting, reaming, tapping, etc. In a state where various tools are arranged in a magazine, The workpieces are automatically machined in a predetermined order.

Since these machining centers need to be machined by selectively exchanging various kinds of tools for various kinds of automated machining, when the tool mounted on the spindle finishes machining for one process, An automatic tool changer (ATC) is indispensable to replace the tool housed in the tool magazine.

The machining center is divided into a short axis type and a multi axis type according to the number of spindles, and is classified into a vertical type machining center or a horizontal type machining center depending on the position of the spindle.

Among these, in the case of a multi-shaft type (multi-type) machining center, it is possible to mass-produce small parts such as a smart phone at a time, thereby increasing the productivity.

In order to increase the productivity, processing speed is very important. In order to do this, it is necessary to improve the machining environment and set the optimum machining program. In addition, the technique of continuously and rapidly machining a workpiece while quickly changing the tool on each spindle is also an important factor for improving productivity.

 Therefore, in a multi-axial machining center, it is required to develop a technology of a tool changer or the like that can exchange tools more quickly and efficiently in order to further improve the productivity.
