The 3-axis cutter grinder machining center is developed from the basic CNC milling machine. It combines all the features and functions of the CNC milling machine. Unlike the CNC milling machine. The machining center has an automatic tool changer that can automatically change during machining knife function. The CNC milling machine does not have an automatic tool changer. And the automatic tool change function cannot realize. This is the difference between the CNC milling machine and the machining center. Today, Demina introduces the automatic tool changer.
The composition of the 3-axis cutter grinder machining center
The automatic tool changer of the 3-axis cutter grinder machining center is composed of a tool magazine. A robot arm, and a drive mechanism. The tool magazine stores the tools required for machining. There are many types of magazines, mainly according to the shape of a variety of types of magazines. Such as bucket magazines, disc magazines, and chain magazines. These magazines have several to hundreds of tools. There are two types of tool magazines used in the common machining centers on the market: the bucket type magazine and the disc type magazine. The chain-type magazine is not used by many manufacturers because of its high price.
The tool change method in the center of the is relatively simple. This type of tool magazine does not have a robot arm. So there is no need to use a robot arm to complete the tool change. The tool change method of the tool magazine is as follows: the tool magazine moves to the main shaft to realize the tool change. This type has the advantages of high-cost performance, convenient maintenance, simple structure, etc.. But the disadvantage is that the tool change speed is slow.
Advantage of 3-axis cutter grinder
The 3-axis cutter grinder machining center mainly performs the tool change operation by the robot arm. The robot removes the tool from the tool magazine and rotates it into the spindle to complete the tool change. Such a tool magazine has the advantages of a fast tool change speed and has the disadvantages of complicated structure. Inconvenient maintenance, and high failure rate.
Although the tool change mode, tool selection mode and tool structure of these tool magazines are different. The 3-axis milling vertical machining center is controlled by the numerical control system. And the tool selection is realized by motor, air pressure or hydraulic and robot.
