Basic precautions for safe operation of CNC engraving machine
1. Before operating the CNC engraving machine, be sure to read the instruction manual carefully to confirm that you are familiar with the performance of the machine. Personnel who are not familiar with the machine are strictly prohibited from operating the machine.
2. Please read and understand the warning signs before operating the CNC engraving machine. Do not move or damage the warning signs installed on the machine. If the warning signs become blurred or disappear, replace them;
3. Before operating the CNC engraving machine, remove ties, rings, watches and other jewelry, and roll the sleeves over the elbows; do not wear loose clothes; limit long hair; it is recommended to wear non-slip shoes or non-slip strips;
4. It is not allowed to wear gloves to operate the machine tool during work;
5. When using a CNC engraving machine, please 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 set up obstacles around the machine tool, work space should be large enough, and provide a glare-free ceiling light;
8. If two or more people are required to complete a task, they should pay attention to each other;
9. It is not allowed to use compressed air to clean machine tools, electrical cabinets and numerical control devices;
10. Drilling, sawing, grinding or processing wood products will produce wood chips and other known carcinogens. 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.
The preparation before the work of the CNC engraving machine
1. The machine tool must be preheated 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 each part first;
2. Before and during the engraving process, check and confirm whether the cooling system (water pump) and lubrication system (oil pump) of the motor are working normally;
3. The tools used should meet the specifications allowed by the machine tool, and severely damaged tools should be replaced in time; the tools used to adjust the tools should not be forgotten in the machine tool; after the tools are installed, one or two trial cuts should be performed;
4. Check the clamping working status of the chuck;
5. When clamping the workpiece, the principle of "installation, installation, installation" must be followed, and it is strictly forbidden to engrave on suspended objects; in order to prevent material deformation, the thickness of the material should be greater than the engraving depth by more than 2mm;
6. The debris in the clamp head must be cleaned up before installing the clamp;
7. When installing the tool, you must first screw the chuck into the lock nut and place it vertically, and install it on the motor shaft together, then insert the tool into the chuck, and then use the upper knife wrench to tighten it slowly. nut. When loading and unloading tools, push-pull method is forbidden for loose nuts, and rotation method is adopted;
8. The length of the tool exposed to the chuck must be determined according to the engraving depth, whether the workpiece and the fixture interfere with each other, etc., and should be as short as possible when the above conditions are met;
9. The starting point of X, Y, Z axis must be defined correctly before processing. The starting point of Z axis must be redefined immediately after tool change, the starting point of X and Y axis 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 avoid 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 knife), put your hand on the red emergency switch button and press it immediately if accidentally occurs.
12. Do not use the CNC engraving machine for unexpected purposes. The CNC engraving machine is used to carve and cut wood, acrylic, plastic and soft metals, etc. Please do not use it to cut hard metals.
The safety precautions during the working process of the CNC engraving machine
1. It is forbidden to touch the tool tip and iron filings by hand. Iron filings must be cleaned up 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, wipe the workpiece with cotton thread, or clean the machine tool during processing;
4. During the operation of the milling machine, the operator shall not leave the post, and shall stop immediately if an abnormal phenomenon is found;
5. Check the bearing temperature frequently. If it is too high, check with relevant personnel;
6. It is not allowed to open the protective door of the machine during processing;
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 place 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, let alone sit or lean on the frame.
10. Do not use in hazardous environments. Do not use power tools in damp or damp places, or expose them to rain. Keep the work area well-lit.
The precautions after the completion of the CNC engraving machine
1. Turn off the power and main power on the machine operation panel in turn, and perform all machine adjustments or maintenance;
2. Check the status 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. It is strictly forbidden to hit the chuck with a wrench when unloading the knife;
5. Check for damaged parts. Before further using the CNC engraving machine, please carefully check the damaged protective cover or other parts to determine whether it can operate normally and perform its expected function.
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 protective covers or other parts.
7. After turning off the power of the machine tool, send the workpiece for inspection and clean the machine tool and the ground.
