Gantry machining center is mainly used for processing large parts. In the long-term use, if the operation is improper, some failures will occur, affecting the normal use of the equipment, delaying the construction period, and causing a series of losses. The common failure is the manipulator tool magazine.
1. In case of an emergency during the tool change process that requires an emergency stop or reset to prevent greater losses, please press reset or emergency stop arbitrarily. At this time, the situation is more complex, which can be divided into two types: tool not communicated and tool communicated.
2. When an alarm that can be recovered by itself appears at the end of tool change, the tool change of the tool magazine will be suspended immediately. Don't panic at this time. Don't press the reset key or emergency stop key. Just turn the feed rate to 0%, turn on the single-stage execution switch button, and then press the cycle to start after the alarm is eliminated until the tool change is completed. Block the single-stage execution and adjust the continuous execution sequence of the feed rate.
3. When the tools of the gantry machining center have been communicated, the tool magazine will be disordered. The manipulator must release the brake to manually swing back. Manually press the electronic valve button of the tool sleeve back to the tool magazine to move the tool sleeve to the tool magazine and then press reset. After removing the tool from the spindle, the mode switch selects MDI mode, and only M06 is output; After the execution, check whether the tool on the spindle is different from the later tool number displayed on the operation panel. If not, remove it manually and replace it with the target tool manually. Repeat M06 for rotor pump; Replace the removed tool.
4. When the tools are not communicated, the tool magazine will not be disordered. Just release the brake of the manipulator to manually swing back, manually press the electronic valve button of the tool sleeve back to the tool magazine to move the tool sleeve to the tool magazine and then press reset.
5. At present, the mechanical hand type tool magazine of FANUC's fragmentary gantry machining center can ensure that the tool magazine will not be disordered in any situation. There is a scene of disordered cutting. The reason is that the operating environment and the service life cause some detection signals to be abnormal, which leads to disordered cutting. When encountering such effects, first identify the defective components according to logic, repair or replace them, first take out all the tools in the tool magazine, and then install the tools one by one from the spindle side.
When there is a fault in the manipulator tool magazine of the gantry machining center, we can carry out preliminary repair according to the above methods. If it still cannot be used normally, we should seek the help of professionals. Do not disassemble the equipment without permission, so as to avoid damage to personal health.
