CNC machining centers CNC machining center with an automatic tool changer. This type of configuration of the machining center can achieve automatic processing methods, but also can achieve automatic conversion of the workpiece processing tools. The automatic device of the magazine can complete the processing of multiple complicated processes in a single setup after being controlled by the system. Compared with other CNC numerical control equipments, it can realize true automatic processing.
The installation and tool change actions of the CNC machining center's tool magazine are different and can be divided into disk magazines, bucket magazines, and chain magazines. This includes the disadvantages of a relatively low tool change rate in the bucket magazine, which can be selected by customers in small machining centers. Nowadays, the most used configuration is the disk magazine. This time, the tool change instructions of the CNC machining center's disk magazine are briefly introduced. And programming knowledge.
The tool change command is an important operation part of the tool processing workpiece. When the machining center completes a processing operation, it must maintain a timely and accurate tool change to ensure the processing of the next operation. The main command for tool change in the magazine is the magazine reverse command, the tool number setting command, and the nearest selection command.
In simple terms, there are mainly two types of tool change programs in the tool magazine. One is that the actions are all controlled by the PLC program, and the other is that the macro program completes the control in the tool change sequence. Single-step action is controlled by PLC. The tool change of the circular tool magazine is generally divided into two tool change actions: tool selection and tool change. When using the machining center, the tool selection command is issued first, and the tool change is performed when the tool change is performed. action. Thus the entire tool change operation saves time, thus changing time of the disc to the magazine manipulator much faster than hats magazine. The programming of macro programs is relatively simple, and it is convenient to change the program flow. It is more convenient to analyze the debugging program. In the preparation of macro programs for disk magazines, a macro program for selecting tools is generally prepared, and the other is a macro program for tool change. The macro program is the simplest and most convenient method in the tool change program.
