Before starting the machine, the operator should refuel the relevant parts according to the instructions of the machine tool, and check the oil standard and oil quantity.
3. Don't place obstacles around the CNC machine tool, and the working space should be large enough.
4. Turn off the power supply of the machine tool before replacing the fuse, and do not touch the motor, transformer, control panel and other places with high voltage power supply.
Generally, two people are not allowed to operate the machine tool at the same time. However, if two or more people need to complete a certain task together, we should pay attention to coordinated action.
6. Before computer operation, you should be familiar with the operating instructions of CNC machine tools. The startup and shutdown sequence of CNC lathe must be consistent with the machine tool.
The specified operating instructions of the bed.
7. Before the spindle starts cutting, the protective door must be closed, and it is forbidden to open the protective door when the program is running normally.
8. After each startup, you must first complete the operation of returning to the reference points of each axis, and then enter other operation modes to ensure the correctness of the coordinates of each axis.
9. The machine tool is not allowed to open the door of the electrical cabinet during normal operation.
10. The processing program can only be operated after strict inspection.
1 1. When setting the cutter manually, pay attention to selecting the appropriate feed speed; When changing the tool manually, the tool rest should have enough indexing distance from the workpiece to avoid collision.
12. If there is an abnormal crisis during the treatment, you can press the "Emergency Stop" button to ensure the safety of personnel and equipment.
13. It is not allowed to use compressed air to clean machine tools, electrical cabinets and numerical control devices.
Second, the preparation work before work
L, the machine tool should be preheated before starting work, and carefully check whether the lubrication system works normally. If the machine tool has not been started for a long time, you can manually supply oil to each part for lubrication first;
2, the use of tools should conform to the specifications allowed by the machine tool, severely damaged tools should be replaced in time;
3. Don't forget the tools used to adjust the knife in the machine tool;
4. Whether the center hole of large-size shaft parts is appropriate, if the center hole is too small, it is easy to be dangerous in work;
5. After installing the tool, try cutting once or twice.
6, check the chuck clamping working state;
7. Before starting the machine tool, the protective door of the machine tool must be closed.
Third, the safety precautions in the process of work
L, it is forbidden to touch the tip and iron filings by hand, and 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 and change speed during processing, and it is forbidden to wipe the workpiece or clean the machine tool with cotton silk;
4. When the lathe is running, the operator shall not leave his post, and the machine tool shall stop immediately if it finds any abnormal phenomenon;
5, often check the bearing temperature, too high should find relevant personnel to check;
6, in the process of processing, are not allowed to open the door of the machine tool;
7, strictly abide by the post responsibility system, the machine tool shall be used by special personnel, and the use of others shall be subject to my consent;
8, the workpiece out of the lathe 100mm, must be set in the extended position protection.
Four, matters needing attention after the completion of the work
L, remove chips, wipe the machine tool, use the machine tool and keep the environment clean;
2. Pay attention to check or replace the worn oil inspection plate on the guide rail of the machine tool;
3. Check the status of lubricating oil and coolant, and add or replace them in time;
4. Turn off the power supply and total power supply on the machine tool operation panel in turn.
5. When the machine tool is turned on, it should follow the principles of zero first (unless there are special requirements), manual, inching and automatic. Machine tool operation should follow the principle of low speed, medium speed and high speed again, in which the running time of low speed and medium speed should not be less than 2-3 minutes. When it is determined that there is no abnormality, work can be started.
7. It is forbidden to knock, straighten and correct the workpiece between the chuck and the top. The next step can only be carried out after the workpiece and the tool are clamped.
8, the operator must stop when changing tools and workpieces, adjusting workpieces or leaving the machine tool to work.
9. The operator shall not dismantle and move the safety and safety protection device on the machine tool at will.
10. Before the machine tool starts machining, it is necessary to check whether the procedures used are consistent with the parts to be machined. After confirmation, close the safety cover and start the machine tool to process the parts.
1 1, machine tool accessories, measuring tools and cutting tools shall be properly kept in good condition, and compensation shall be made for loss and damage.
12. After the training, clean the machine tool, keep it clean, move the tailstock and the carriage to the end of the bed, and cut off the power supply of the machine tool.
13. When the machine tool fails or is abnormal during work, it should immediately stop to protect the site and report to the site immediately.
14, operators are prohibited from modifying machine parameters. If necessary, the equipment manager must be informed and asked to make changes.
15. Understand the technical requirements of the part drawing and check whether the blank size and shape are defective. Choose a reasonable method to install parts.
16, correctly select CNC turning tools to ensure accurate and firm installation of parts and tools.
17, understand and master the control and operation panel of CNC machine tools and its operation essentials, accurately input the program into the system, simulate inspection and trial cutting, and do all the preparatory work before processing.
18, in the process of machining, if the lathe operation sounds abnormal or fails, it should immediately stop and check and report to the instructor to avoid danger.
I hope the above information can help you.
