Safety Operation Guide for CNC Engraving Machine

When using a CNC engraving machine, we should strictly abide by the operating rules of the CNC engraving machine, and carefully study the user manual and safety guidelines before using it. Only in this way can work risks be reduced. Today Leapion laser manager shares a safe operation guide for CNC engraving machine from Leapion laser, hope it will be helpful to you.

First, the basic precautions for safe operation of CNC engraving machine

1. Before operating the CNC engraving machine, be sure to read the operating instructions in detail and confirm that they are familiar with the performance of the machine. Those who are not familiar with the machine are strictly prohibited from operating the machine.

2. Before operating the CNC engraving machine, please read and understand the warning signs. Do not move or damage the warning signs installed on the machine. If the warning signs become blurred or removed, please replace them;

3. Before operating the CNC engraving machine, remove the tie, ring, watch and other jewelry, and roll the sleeves over the elbow; do not wear loose clothes; limit long hair; it is recommended to wear non-slip shoes or non-slip floor strips;

4. It is not allowed to wear gloves to operate the machine tool during work;

5. When using a CNC engraving machine, be sure to wear approved safety glasses/face shields;

6. Wear ear protectors (earplugs or earmuffs) when operating for a long time;

7. Be careful not to place obstacles around the machine tool, the working space should be large enough, and provide glare-free overhead lighting;

8. If two or more people are required to complete a certain task, they should pay attention to mutual coordination;

9. It is not allowed to use compressed air to clean machine tools, electrical cabinets and NC units;

10. Drilling, sawing, grinding or processing wood products will produce wood chips and other substances known to be carcinogenic. Avoid inhaling the dust generated by wood products, or use dust masks or other protective measures to avoid inhaling the dust generated by wood products.

11. Do not operate the CNC engraving machine when you are tired or under the influence of drugs, alcohol or any drugs.

Second, the preparation before the work of the CNC engraving machine

1. The machine tool must be warmed up before starting to work, and carefully check whether the lubrication system is working properly. If the machine tool has not been started for a long time, you can manually supply oil to all parts first;

2. Before and during engraving, check and confirm whether the cooling system (water pump) and lubrication system (oil pump) of the motor are working properly;

3. The tools used should be in accordance with the specifications allowed by the machine tool, and severely damaged tools should be replaced in time; the tools used for adjusting the tools should not be forgotten in the machine tool; after the tools are installed, one or two trial cuttings should be performed;

4. Check the status of the clamping work of the chuck;

5. When clamping the workpiece, the principle of "installation, installation, and installation" must be followed, and it is strictly forbidden to engrave on suspended materials; in order to prevent deformation of the material, the thickness of the material should be more than 2mm greater than the engraving depth;

6. The debris in the chuck head must be cleaned up before installing the card tool;

7. When installing the tool, you must first screw the chuck into the lock nut and place it upright, and install it on the motor shaft together, then insert the tool into the chuck, and then use the upper knife wrench to slowly tighten the nut. When loading and unloading the tool , The push-pull method is prohibited for the loose nut, and the rotation method is used;

8. The length of the tool exposed to the chuck must be determined jointly according to the engraving depth, whether the workpiece and the fixture interfere with each other, and should be as short as possible when the above conditions are met;

9. Before machining, the starting point of X, Y, Z axis must be defined correctly. After changing the tool, you must immediately redefine the starting point of the Z axis, and the starting point of the X and Y axes cannot be changed;

10. When using the tool setting instrument to define the tool setting point, it is strictly forbidden to rotate the spindle to prevent damage to the tool setting instrument; it is strictly forbidden to fill the tool setting instrument with water or oil, and the tool setting instrument must be covered with a cup when not in use;

11. Before starting processing (cutting the knife), place your hand on the red emergency switch button and press it immediately if there is an accident.

12. Do not use the CNC engraving machine for unexpected purposes. CNC engraving machine is used to carve and cut wood, acrylic, plastic and soft metal, etc. Please do not use it to cut hard metal.

Third, the safety precautions during the working process of the CNC engraving machine

1. It is forbidden to touch the knife tip and iron filings with your hands. The iron filings must be cleaned with iron hooks or brushes;

2. It is forbidden to touch the rotating spindle, workpiece or other moving parts by hand or in any other way;

3. It is forbidden to measure the workpiece, change the speed during the processing, and not to wipe the workpiece with cotton thread, nor to clean the machine tool;

4. During the operation of the milling machine, the operator shall not leave the post, and the machine tool shall stop immediately if it finds an abnormal phenomenon;

5. Check the bearing temperature frequently. If it is too high, you should find relevant personnel to check;

6. During processing, it is not allowed to open the machine protection door;

7. Strictly abide by the post responsibility system, the machine tool is used by a dedicated person, and the use of others must be approved by the person;

8. It is strictly forbidden to put any objects on the beam and baffle of the machine tool to avoid falling and hurting people;

9. It is strictly forbidden to lie on the machine during operation, and it is not allowed to sit or lean on the machine frame.

10. Do not use in dangerous environments. Do not use power tools in damp or damp places, or expose them to rain. Keep the work area well-lit.

Fourth, the precautions after the completion of the CNC engraving machine

1. Turn off the power supply and the main power supply on the machine operation panel in turn, and perform all machine adjustments or maintenance;

2. Check the state of lubricating oil and coolant, add or replace in time;

3. Remove chips and wipe the machine tool to keep the machine tool and the environment clean;

4. When unloading the knife, it is strictly forbidden to hit the clamp head with a wrench;

5. Check the damaged parts. Before using the CNC engraving machine further, check the damaged guards or other parts carefully to determine whether it can operate normally and perform its expected functions.

6. Check the alignment of moving parts, binding of moving parts, damage to parts, installation and any other conditions that may affect its operation. Correctly repair or replace damaged guards or other parts.

7. After turning off the power of the machine tool, send the workpiece for inspection, clean up the machine tool and the ground.
