What safety precautions should be taken when using semiconductor optical dedicated milling machines?

Safety precautions to be observed during the operation of semiconductor optical dedicated milling machine:

1. Personal Protective Equipment (PPE)：

• Operators must strictly refrain from wearing loose clothing or having long hair while working to prevent entanglement with machinery.
• Wear protective eyewear, masks, earplugs, dust masks, work clothes, and safety footwear to prevent flying debris from harming your eyes, respiratory system, and other parts of your body.

1. Equipment Inspection：

• Perform a safety check of the surrounding area prior to use to ensure no person or object interferes.
• Inspect the condition of machine tools, cutting tools, grinding wheels, and other components to ensure proper equipment operation.
• Inspect the millstone, mill head, and protective guards for tightness. If loose, please tighten promptly.
• Inspect power cords, cables, plugs, etc., for any damage. Replace immediately if found.

1. Professional Training：

• Operators must undergo professional training, familiarize themselves with the operation procedures, equipment structure, performance, and precautions of the milling machine, and pass the assessment before they can be employed.

1. Standardized Procedures：

• Operate the milling machine strictly according to the operational procedures and strictly prohibit overloading.
• Properly adjust the rotation speed, feed rate, and cutting depth to prevent equipment overload and potential accidents.
• Be mindful of the relative position of the protective shields to prevent collisions during machine tool adjustments or tooling operations.
• Coolant must be adequately filled to ensure optimal cooling performance and prevent equipment damage or fires due to high temperatures caused by friction.

1. Handling Exceptional Situations：

• During the processing, if any abnormalities or sharp noises occur, immediately shut down for inspection and do not attempt to force a solution.
• In the event of a malfunctioning safety device, the machine should be immediately shut down and operations can only resume after it has been repaired by a professional.

1. Post-operation processing：

• After processing, the equipment should be cleaned and adjusted, including cleaning the waste material from the processing surface, gradually cooling it down, and lubricating the machine tool sections with oil.
• Remove the grinding wheel, workpiece, and fixture for cleaning and proper storage.
• Regular maintenance and inspections of the milling machine are conducted, including checking for loose parts such as slides, guides, and cutting tools, as well as determining if oiling and lubrication are needed.

1. Environmental Condition Control：

• Avoid using machine tools in environments with significant temperature fluctuations or vibration interference to ensure stability.
• Ensure that chip channels are clear and that cutting fluid flow is adequate to help chips stay away from the grinding area, preventing chip accumulation from affecting grinding accuracy.

1. Other important notes：

• Mineral oil-based coolants are flammable; fire prevention measures should be observed during operation.
• Do not arbitrarily open the electrical control door during machine tool processing to prevent electric shock.
• Prohibit frequent power supply. Power off the machine tool only after the CNC system has been fully started.
• Each time the machine tool is turned on, it requires the axes to return to the reference point.
• Maintain the cleanliness of machine tools and clean them after each day's production.

In summary, strict adherence to all safety measures is required during the operation of semiconductor optical dedicated milling machines to ensure the safety of operators and the long-term stable operation of the equipment.
