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

Pay attention to the following safety precautions when using the semiconductor optical dedicated milling machine:

1. Personal Protective Equipment：

• 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, protective clothing, and non-slip safety shoes to prevent flying debris from harming your eyes, respiratory system, and other parts of your body.

• Conduct a safety check of the surrounding area prior to use to ensure no one or anything interferes.

• Inspect the condition of machine tools, cutting tools, grinding wheels, and other components to ensure proper equipment operation.

• Check the millstone, mill head, and protective guards for firmness. If loose, please tighten immediately.

• Inspect power cords, cables, plugs, etc. for any damage; replace promptly if necessary.

• 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.

• Operate the milling machine strictly according to the operational procedures, and strictly prohibit overloading.

• Properly adjust the spindle speed, feed rate, and cutting depth to prevent equipment overload and potential accidents.

• Note the relative position of the protective guards to prevent collisions during machine tool adjustments or knife setting.

• Coolant must be replenished to ensure effective cooling and prevent damage to equipment or fires due to high temperatures resulting from friction.

• During the processing, if any anomalies or sharp noises occur, stop the machine immediately for inspection and do not attempt to force a solution.

• In the event of a failed safety device, immediately shut down the equipment and only resume operation after a professional has repaired it.

• After processing, the equipment should be cleaned and adjusted, including cleaning off the waste material from the processed 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, and determining if oiling and lubrication are needed.

• Avoid using machine tools in environments with drastic temperature changes or vibration interference to ensure stability.

• Ensure the chip channels are clear and that the coolant flow is adequate to help particles stay away from the grinding area, preventing chip accumulation from affecting grinding accuracy.

• Mineral oil-based coolants are flammable; fire precautions must be taken during operation.

• Do not open the electrical control door arbitrarily during machine tool processing to prevent electric shock.

• Prohibit frequent power-on operations. Disconnect the machine tools only after the CNC system has been fully initiated.

• Each time the machine tool is turned on, it requires the axes to return to the reference point.

• Maintain cleanliness of machine tools and clean them after each day's production.

In summary, it is crucial to strictly adhere to all safety measures when operating semiconductor optical specialized milling machines to ensure the safety of operators and the long-term stable operation of the equipment.
