Products - ATC CNC Wood Carving Machine with Tool Changer

Since the rotary tool rest and turret head type changer can not accommodate too many bits, they cannot meet the processing needs of complex parts. Therefore, ATC CNC machines mostly use automatic changers with tool magazines. The device with a tool magazine consists of a magazine and a tool changing mechanism, and the changing process is more complicated. First of all, all the bits used in the machining process should be installed on the standard holder, and after pre-adjusting the size outside the machine, put them into the magazine in a certain way. When changing, first select the bit in the magazine, and then the changer will take out the bit from the magazine or the spindle for exchange, put the new bit into the spindle, and put the old bit back into the magazine. The magazine has a large capacity and can be mounted on the side or above the headstock. Since there is only one spindle in the headstock of the machine with the automatic tool changing magazine, the rigidity of the spindle components should be high to meet the requirements of precision machining. In addition, the number of bits in the magazine is large, so multi-process processing of complex parts can be carried out, which greatly improves the adaptability and processing efficiency of the machine. The ATC system with magazine is suitable for drilling centers and machining centers.

In the automatic tool changing system, the device that realizes the transfer and loading and unloading of the tool between the magazine and the spindle is called the tool changer. There are two ways to exchange tools: the relative movement of the magazine and the spindle, and the manipulator. The device that uses the relative movement of the magazine and the spindle to realize the tool exchange must first return the used tool to the magazine when changing the tool, and then take out the new tool from the magazine. The two actions cannot be performed at the same time, and the tool change time longer.

However, the manipulator tool changer can grab and load and unload the bits in the spindle and the magazine at the same time during changing, so the changing time is further shortened. The method of tool exchange using a robot is the most widely used. This is because the manipulator is flexible in changing, fast in action, and simple in structure. The manipulator can complete a series of actions such as grasping – drawing – turning – inserting – returning. In order to prevent the bit from falling, the movable claw of the manipulator is equipped with a self-locking mechanism.
