Types and differences of CNC machining center tool magazines;

There are two types of tool magazines in CNC machining centers, one is a manipulator disc tool magazine, and the other is a bucket hat tool magazine. The function of the tool magazine in the machining center is to store the tool first, and it is one of the main components of the automatic tool changing equipment. According to the number of tools stored in the tool magazine and the method of tool retrieval, the tool magazine can be designed into different types. The tool change process of the machining center machine tool is messy. When machining parts with a machining center, the different types of tools needed in the machining process should be installed in the tool pockets of the tool magazine. After being pre-scaled outside the machine, it should somehow be placed in the tool magazine. When changing the tool in the machining center, first select the tool in the tool magazine, and take out the tool from the tool magazine and the spindle through the tool changing device. After tool replacement, load the new tool into the spindle and put the old tool back into the magazine. Generally speaking, a magazine for storing tools can store 16 or 24 tools. Hat knife magazine and disc magazine? what is the difference

Bucket tool magazine: The tool change mode of the tool magazine is to change the tool by moving the spindle up and down. When the tool on the spindle enters the clamping slot of the tool magazine, the spindle moves up and separates from the tool, and then the tool magazine rotates. When the tool to be replaced is aligned directly under the spindle, the spindle moves down, allowing the tool to enter the taper hole of the spindle. After clamping the tool, the tool magazine returns to its original position.

Advantages: This type of tool magazine has a simple structure, low requirements for the surrounding environment, low failure rate and low price.

Disadvantages: long tool change time and low power. Affects the working stroke of the spindle of the machining center.

Disc magazines are also known as robotic magazines.

Disc-type tool magazine: The manipulator automatically changes the tool, with obvious advantages and fast tool change. The working principle is that the robot arm pulls out the tool in the tool magazine and the spindle at the same time, rotates 180 degrees, and inserts the tool at the same time.

Advantages: fast tool changing speed, high relative processing power of the machine tool.

Disadvantages: The failure rate is relatively high, and the requirements for the surrounding environment are high. (For example, air pressure, knife release action, and knife release signal. A common fault situation is that the knife is pulled out when the release claw is not fully opened, which will cause damage to the spindle, mechanical arm and cam.
