toolchanger

A toolchanger is a mechanism used in automated manufacturing and machining to rapidly change tools on a machine tool, such as a CNC milling machine or lathe. The primary function of a toolchanger is to increase efficiency and flexibility by allowing a single machine to perform a variety of operations without manual intervention.

There are several common types of toolchangers. Rotary toolchangers, often referred to as "revolvers," store tools in a rotating carousel. As a new tool is needed, the carousel rotates to bring the desired tool into position, and then it's transferred to the spindle. Linear or magazine toolchangers typically store tools in a linear rack or magazine. An arm or shuttle then moves to pick up the required tool from the magazine and insert it into the spindle.

The process of tool changing usually involves a tool magazine, a tool holder, and an automatic tool changer mechanism. When the machine's controller signals for a tool change, the ATC mechanism engages with the tool currently in the spindle and the new tool in the magazine. The old tool is removed, and the new tool is inserted into the spindle. This entire process is automated and takes a relatively short amount of time, often just a few seconds.

Toolchangers are crucial for operations that require multiple machining processes, such as drilling, milling, and tapping, on a single workpiece. By eliminating the need for manual tool swaps, they significantly reduce machine downtime, improve productivity, and minimize the risk of human error. This automation is essential for high-volume production environments and complex manufacturing tasks.
