This type of machine does not have a conventional tool magazine and tool changer. Instead, multiple (generally 3 to 18) spindles are mounted side by side on the spindle frame. Each spindle is driven directly by its own motor and a different tool is mounted on each spindle. When changing the tool, the tool is not exchanged on the spindle, but the workpiece mounted on the fixture is quickly moved from the machining position of one spindle to the other spindle with different tools to realize the tool change and process immediately. This movement time is the tool change time and is very short. The tool change is quickly completed by the jig, eliminating the need for a complicated tool change mechanism.
This type of machine tool is very different from the usual machining center structure. It is useful not only for machining that requires quick tool change but also for simultaneous multi-axis machining. And it’s suitable for use on high-efficiency production lines.
Of course, this type of machine is usually expensive, and you can also consider solving the problem of efficiency and price by purchasing an automatic tool change spindle:
