What safety precautions should be taken when using a vertical machining center machine?

Inspection and preparation before operation
Before starting the vertical machining center machine, the operator should complete a series of inspections. This includes checking whether the appearance of the equipment is abnormal, whether the power cord and control line are intact, whether the control panel buttons are sensitive, and whether the emergency stop button is in the reset state. In addition, the lubricating oil level, coolant status, and air pressure system should be checked to see if they are normal. All tools, gauges, and fixtures should be prepared in advance and placed in order to avoid temporary operations during processing.

Correct use of personal protective equipment
Operators should wear work clothes, safety shoes, and goggles that meet the requirements, and avoid loose clothing or wearing accessories to avoid being caught in the equipment. Operators with long hair should put their hair up and avoid getting close to the rotating spindle area. If there are processes that splash cutting fluid or generate dust, masks or face shields should also be worn to reduce the inhalation of harmful substances or splashing the face.

The processing program must be confirmed to be correct
Before processing, the program content must be strictly confirmed, including part coordinates, tool compensation, feed speed, and spindle speed. Any unverified program shall not be run directly on the actual workpiece. A dry run simulation shall be performed first to confirm that the program has no logical errors or path interference. After the program is entered, it shall be properly saved and the version shall be marked to prevent the misuse of old versions or wrong files.

The clamping of the workpiece and the tool shall be firm and reliable
Before processing, it is necessary to ensure that the workpiece is firmly fixed on the workbench or fixture. Loose workpieces or improper clamping angles may lead to reduced processing accuracy and even flying accidents. The clamping of the tool shall also ensure that the depth is appropriate, the nut is locked, and there is no chipping, cracking or abnormal wear. Check the wear of the tool regularly to avoid breakage during use.

Concentrate on the processing process
The operator shall focus on the current operation and shall not leave the post or carry out activities unrelated to processing without authorization. During the program operation, pay close attention to the processing sound, spindle operation, chip status and other signals to promptly determine whether there is abnormal vibration, overload or other problems. If there is an abnormality, press the emergency stop button immediately and do not force the processing to continue.

The processing area shall not be touched at will
During the processing process, it is strictly forbidden to put your hands into the equipment or near the rotating parts. Especially during the operation of the spindle or tool change, any adjustment of the tool, fixture, or cooling pipe should be performed after the spindle has completely stopped. If processing monitoring is required, it should be performed at a distance outside the observation window to avoid personal injury caused by cutting splashes.

Safe use of automatic tool change system
During automatic tool change, the operator must not approach the tool magazine and spindle area to prevent pinching or collision accidents caused by misoperation. Before changing the tool of the equipment, it should be confirmed that the tool length and weight are within the allowable range of the machine tool, and the tool code is consistent with the call in the program. Before use, the operation of the robot arm, solenoid valve, and tool arm system should be checked regularly to ensure smooth operation.

Precautions for using coolant and lubrication system
The coolant must be kept clean to avoid slipping in the processing area or corrosion of the equipment due to contamination. When replenishing the coolant, a mixed liquid with a specified ratio must be used, and other ingredients must not be added at will. The oil level of the lubrication system should be checked daily to prevent poor lubrication from causing wear of the slide rails. Regular replacement of oil products and cleaning of filters are important guarantees for the stable operation of the equipment.

Keep the environment around the equipment clean and tidy
The equipment should be kept ventilated and dry, and no debris should be piled up. If cutting fluid or coolant overflows on the ground, it should be cleaned immediately to prevent slipping accidents. After the operation is completed, the chips, workbench and tool should be cleaned in time, and the machine should be shut down and powered off according to the regulations.

Perform regular maintenance
After the equipment has been running for a period of time, it should be regularly maintained by professionals, including spindle inspection, screw lubrication, guide rail scraping, control system detection, etc. Maintenance records should be registered in detail, and the content of each maintenance, problems found, and replaced parts should be archived to track the usage and prevent failures in advance.

Emergency measures for emergencies
Operators need to be familiar with the location and use of emergency stop devices. Once electrical failures, abnormal noises, or loose workpieces are found, measures should be taken quickly. If necessary, the main power supply should be cut off immediately, and the maintenance personnel should be notified to handle it. When performing inspections or maintenance, ensure that the equipment is completely powered off and hang a "maintenance" warning sign.

Comply with operating procedures and training systems
All operators must undergo systematic training before they can take up their posts and understand the basic structure, operating procedures, safety regulations and emergency measures of the equipment. Unauthorized personnel are prohibited from operating the equipment, especially in areas involving tool adjustment, program modification, electrical wiring, etc., which should be performed by professional technicians to avoid accidents caused by misoperation.
