When replacing the tool of a woodworking engraving machine, you need to pay attention to the following points:
1. Ensure safety: Before replacing the tool, you must turn off the power of the equipment to prevent accidental startup and cause injury.
2. Clean the tool and tool holder: Use an air gun or brush to remove debris, dust and other foreign matter on the tool shaft and tool holder, ensure that the tool holder is clean, and avoid blade breakage or "edges" on the cutting surface.
3. Correctly install the tool: Turn the wrench counterclockwise to loosen the screw, wipe the blade clean and rotate it 90 degrees to install it, ensure that the bottom of the blade fits the tool holder, and lock the screw clockwise. Note that there is a mark point on the surface of the blade to ensure consistent orientation and avoid changing the new and old blade surfaces by mistake.
4. Check the tool status: Check whether the blade is broken before installation. If it is broken, replace it immediately to avoid safety accidents and damage to the product. Check the screws frequently to prevent the screws from loosening.
5. Lubrication treatment: When changing the tool, the screws need to be lubricated with some engine oil to prevent them from being difficult to loosen next time.
Through the above steps and precautions, the safety and efficiency of the woodworking engraving machine when changing the tool can be ensured.
