The company in line with the principle of win-win, adhering to the "high quality and low price, customer first" purpose, in good faith to treat every customer, relying on professional sound after-sales service system, constant innovation. CNC machine safety operation procedures:
1. While at work, please wear good clothes, safety shoes, and put on the helmet and goggles, and are not allowed to wear gloves operation of CNC machine tools, are not allowed to tie.
2. Before driving, should check each part of the nc machine tools are in good condition, whether the button can automatically reset. Before starting, the operator should according to the regulation to the related parts of the machine instruction manual refueling, and check the oil, oil amount.
3. Clear of obstacles around in the numerical control machine tool and the work space should be large enough.
4. Should be turn off machine power supply before replacing the fuse, must not to contact with the hand motor, transformer, places that have requirements of high voltage power supply control board, etc.
5. Generally does not allow two people at the same time operating machine tools. But a job for two or more people together to complete, should pay attention to the action will be coordinated to each other.
6. Computer before operation should be familiar with the operating instruction manual of CNC machine, CNC lathe, boot, shutdown sequence, must according to the machine
Bed the provisions of the manual operation.
7. The spindle start before start cutting must close door, normal program run in it is strictly prohibited to open the door.
8. In every time after power on, you must first complete the axis of returning reference point operation, and then enters the other operation mode, in order to ensure the correctness of the axis coordinates.
9. During normal operation of the machine tool are not allowed to open the electric cabinet door.
10. The processing programs have to pass strict inspection before operation.
11. When manual for knife, should pay attention to choose the appropriate feed speed; Manual tool change, tool post artifacts when there should be enough to turn a distance not collision.
12. During processing, such as abnormal crisis situation can press the emergency "stop" button, in order to ensure personal and equipment safety.
13, are not allowed to use compressed air to clean machine tools, electrical cabinets and NC unit.
Second, the preparing work before work
L, machine tool working with preheating before start work, carefully check whether the lubrication system work normally, such as machine tool for a long time did not start, can use first manually to each part of the oil supply lubrication;
2, the use of tools shall be in conformity with the specifications of the machine allows, has serious damaged tool needs to be changed in a timely manner;
3, adjust the knives used tools don't forgotten inside the machine;
4 hole at the center of the shaft parts, large size is appropriate, center hole is too small, proves dangerous work;
After installation of, tool try cutting shall be carried out once or twice.
6, check the status of a chuck clamping work;
7, before start the machine, must turn off machine door.
Third, security considerations in the process of work
L, no contact with hands point must use iron and scrap iron, scrap iron hooks or brush to clean up;
2, banned by hand or any other way to contact is rotating spindle or artifacts or other moving parts;
3, prohibit during processing volume, speed, more can't live wiped with cotton silk artifacts, also can't cleaning machine;
Operators are not allowed to leave 4, operate the lathe, and machine tools found anomalies immediately stops;
5, often should check bearing high temperature, to find relevant personnel to inspect;
6, in the machining process, are not allowed to open the door of machine;
7, strictly abide by the post responsibility system, machine tool use, others use shall be subject to the consent;
8, 100 mm beyond the workpiece out of lathe, must set shield in out position.
Fourth, work after the completion of the matters needing attention
L, remove scraps, wipe the machine tool, use the machine and environment clean;
2, pay attention to check or replace the damaged grinding machine tool guide rail oil was found on the board;
3, check the status of lubricating oil, coolant, and add or replace in time;
4, in turn, turn off machine power and total power on the operation panel.
5, machine tool should follow the first back to zero when the phone is switched on (except special requirement), manual, inching and automatic principles. Machine tool operation should follow the principle of first low-speed, medium-speed and high-speed, low-speed, medium-speed operation time shall not be less than 2-3 minutes. After confirm no abnormalities, can begin to work.
7, it is strictly prohibited on the chuck, tapping, straightening and fixed between the top workpiece, must confirm the workpiece and tool clamping rear can work for next step.
8, the operator change the cutting tool, workpiece, adjusting the workpiece at work or when you leave the machine must be shut down.
9, the insurance and safety protection device on the machine, the operator shall not be arbitrarily disassembled and mobile.
10, before start the machine must use program used by parity check whether match the processed parts, after being confirmed, can pass good security guard, to start the machine tool parts processing.
11 and measuring tool, cutting tool, machine accessories should be properly kept, intact and good compensation, loss or damage according to price.
12, after the completion of the training should be cleaning the machine, keep clean, remove the tailstock and the carriage to the end of the bed position, and cut off the machine power supply.
13, machine tools in the workplace when failure or abnormal phenomenon, should immediately stop, protect the scene and immediately report the scene at the same time.
14, operators are strictly forbidden to modify machine parameters. When necessary, must inform facility manager, please modify equipment administrator.
15 and understand the technical requirements of the part drawing, check the blank size, shape, with and without defects. Choose reasonable parts installation method.
16 and correctly choosing the numerical control turning tools, installation, spare parts and tools to ensure the accurate and firm.
17, to understand and master the nc machine tool control and operation panel and the operation main point, the program accurately input system, and completes the machining and simulation examination, the preparations for the former.
18, processing such as found in the process of lathe the voice is not normal operation or failure, should immediately stop check and report to guide teachers, lest appear dangerous.
The following is a wire-cut machine safety operation procedures:
1. Check the circuit system of the switch knob and open the ac regulated power supply, open the power switch first, after the high voltage switch, after 5 minutes, may be connected to the negative line.
2. Console after open the power switch, should first check the output data of stabilized voltage supply and neon digital tube is normal, enter information for about 5 minutes, the trial operation, the normal, before processing.
3. The cutting high frequency power switch should be in the off position before processing, under the workings of the molybdenum wire, can open high frequency power supply, and shall remain in the 60 ~ 80 v is advisable. Parking should be shut down before the high frequency power supply.
4. Cutting processing, should add cooling fluid. Molybdenum wire contact with the workpiece, shall check the voltage and the electric hydraulic value of high frequency power supply is normal, should not be in the arc case processing.
5. Fails, the high frequency power supply must be switched off, the analysis reason, electrical boxes are not allowed to add other items, especially the metal equipment.
6. Prohibited by hand or contact wire electrode conductor, or artifacts. Also don't use wet hand contact switch, or other electrical parts.
