The tool magazine commonly used in machining center includes hat type tool magazine and disc type tool magazine, and there is also a kind of chain type tool magazine. This kind of tool magazine is generally installed on gantry machining center and horizontal machining center, but rarely used in vertical machining center.
Characteristics of bamboo hat type tool magazine
The biggest feature of the bamboo hat type tool magazine is its high cost performance and simple structure. Its tool change speed can be completed in 8s. It is better to use it in small batch production. The maintenance and maintenance of the bamboo hat type tool magazine is simple and convenient. The disadvantages of the bamboo hat type tool library are that the tool change speed is slow, when the handle is placed in the magazine, the cone surface is open without protection, and the cone surface is easy to stick Dirt will directly affect the accuracy of tool repeated installation.
Characteristics of disc type magazine
Disk magazine can be called manipulator magazine and arm magazine. They are different in each place, but they are the same. They are all disc magazine. The tool change speed of disc type magazine is fast, complex and expensive. The tool change speed of disc magazine is less than 4 s because of its tool change action: the mechanical arm pulls the tool from the tool magazine and the main shaft at the same time, and installs it to the spindle and magazine through 180 ° rotation, thus completing the tool change process. The price of the magazine is much higher than that of the hat magazine. The magazine can load up to 40 tools. The disc type magazine is extremely strict on the weight of the tool. Once the loaded tool exceeds the bearing range of the magazine, the tool will be easily thrown out of the magazine, which is easy to cause accidents. If the length of the tool exceeds the specified size, it will collide with the tool in the process of tool change, which will cause damage to the magazine and the tool.
According to the characteristics of the above magazine, which is better? The problem is clear at a glance. The bamboo hat type magazine is cheap and easy to maintain, while the disc magazine is fast and expensive.
