11. Do not operate the CNC engraving machine when fatigued or under the influence of drugs, alcohol or any drugs.
Preparation before CNC engraving machine work
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 all parts first;
2. Before and during the engraving, 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 allowable specifications of the machine tool, and the 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 carried out;
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 material thickness should be more than 2mm larger than the engraving depth;
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 slowly tighten it with the upper knife wrench. nut. When loading and unloading tools, the loose nut is prohibited from pushing and pulling, and the rotating method is used;
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 it should be as short as possible when the above conditions are met;
9. The starting point of X, Y and Z axes must be correctly defined before processing. The starting point of Z axis must be redefined immediately after tool change, and the starting point of X and Y axis cannot be changed;
10. When using the tool setter to define the tool setting point, it is strictly forbidden to rotate the spindle to avoid damage to the tool setter; it is strictly forbidden to fill the tool setter with water or oil, and the tool setter must be covered with a cup when not in use;

3. It is forbidden to measure the workpiece and change the speed during the processing, 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 should stop immediately when abnormal phenomena are found;
5. Always check the bearing temperature. If it is too high, it should be checked by relevant personnel;
6. It is not allowed to open the protective door of the machine during processing;

2. Check the status of lubricating oil and coolant, and add or replace it 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 use the wrench to hit the chuck;
5. Check for damaged parts. Before using the CNC router any further, carefully inspect any damaged guards or other parts to determine if it is functioning properly and functioning as intended.
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.
