CNC turretThe automatic tool changing program of CNC turret is realized through a series of complex mechanical and electrical controls, ensuring that the tool can be changed quickly and accurately during the processing, improving the processing efficiency and precision.
First of all, the implementation of the automatic tool changing program depends on the control of the CNC system. The CNC system receives instructions from the programmer and determines the tool to be replaced according to the requirements of the processing technology. When the tool needs to be changed, the CNC system will send a tool change signal to start the automatic tool changing program.
In terms of mechanical structure, CNC turret is usually composed of a tool disk, a tool holder, a tool changing mechanism, etc. Different tools are installed on the tool disk, and the tool holder is used to fix the tool. The tool changing mechanism is responsible for removing the currently used tool from the spindle and installing the required tool on the spindle.
The tool changing process is generally divided into the following steps: First, the spindle returns to the tool changing position, which is usually a specific safe position to ensure the safety of the tool changing process. Then, the manipulator or other device in the tool changing mechanism moves to the position of the current tool, grabs it and removes it from the spindle. Next, the robot will place the removed tool at the designated position on the tool tray, move to the position of the required tool, grab it and install it on the spindle. Finally, the spindle restarts and continues processing.
In order to ensure the accuracy and reliability of tool change, CNC turret is usually equipped with various sensors and detection devices. For example, the position sensor is used to detect the position of the spindle and the tool to ensure that the tool change mechanism can accurately grab and install the tool. The force sensor can detect the change of force during the tool change process to prevent the tool from getting stuck or not being installed firmly.
In terms of programming, the programmer needs to specify the tool change instruction in the CNC program and set related parameters such as tool number, tool change speed, etc. The CNC system will control the turret to automatically change the tool according to these instructions and parameters.
In short, the automatic tool change program of CNC turret is realized through the control of the CNC system, the coordination of the mechanical structure and the detection of various sensors. This process requires a high degree of accuracy and reliability to ensure the smooth progress of the processing process. When using CNC turret, operators need to understand the working principle of the automatic tool change program and master the correct programming methods and operating skills to give full play to the advantages of CNC turret and improve processing efficiency and quality.
