The advantages of the bucket hat type tool magazine: high cost performance, simple structure, suitable for small batch production; The maintenance and maintenance of the type tool magazine is simple and convenient; Disadvantages: The tool change speed is slow (8-10S); When the tool handle is placed in the tool magazine, the tapered surface is open and unprotected, and the tapered surface is easy to stick to dirt and directly It affects the accuracy of the repeated installation of the tool; the tool magazine must be "returned to zero" every time the machine is turned on. 850 Machining Center (Figure) 850 Machining Center Disc-type tool magazine Disc-type tool magazine, also known as manipulator tool magazine, is called differently in every place, but they are all the same, all of which are disc-type tool magazines.
Advantages of disc type tool magazine: Tool change is fast and reliable (2-4S); the memory of the tool pocket number and tool number is permanent by the CNC system, and the tool magazine can be restored to the original state before shutdown without "returning to zero" after turning it off. state. Disadvantages: complex structure and high price; troublesome maintenance, the cam box of the tool magazine needs to be regularly replaced with gear oil for lubricating and cooling; the disc-type tool magazine has extremely strict restrictions on the weight of the tool, once the loaded tool exceeds the bearing capacity of the tool magazine If the length of the tool exceeds the specified size, the tool will be easily thrown out from the tool magazine, which may easily cause accidents; the disc-type tool magazine also has certain restrictions on the length of the tool. It will cause damage to the tool magazine and the tool.
