CNC machine tool safety regulations

Safety operating procedures for CNC machine tools

1. When working, please wear work clothes, safety shoes, and wear a helmet and protective goggles, and are not allowed to wear gloves to operate the CNC machine tools, or tie a necktie.

2. Before starting the machine, you should check whether the parts and mechanisms of the CNC machine tool are intact and whether the buttons can be reset automatically. Before starting the machine, the operator should refuel the relevant parts according to the provisions of the machine tool instruction manual, and check the oil mark and oil volume.

3. Do not place obstacles around the CNC machine tool, the workspace should be large enough.

4. Before replacing the fuse, you should turn off the power of the machine tool, and never touch the motor, transformer, control board and other high-voltage power supply with your hands.

5. Generally do not allow two people to operate the machine at the same time. But a job such as the need for two or more people *** with the completion, should pay attention to each other will be coordinated action.

6. Before operating the machine should be familiar with the operating instructions of the CNC machine tool, CNC lathe start-up, shutdown sequence, be sure to operate in accordance with the provisions of the machine

Machine instructions.

7. Spindle start cutting before you must close the guard door, program normal operation is strictly prohibited to open the guard door.

8. After each power on, you must first complete the return to the reference point of each axis of the operation, and then enter the other mode of operation to ensure the correctness of the coordinates of each axis.

9. It is not allowed to open the door of the electrical cabinet when the machine is in normal operation.

10. The machining program must be strictly checked before operation.

11. Manual tool setting, attention should be paid to selecting the appropriate feed rate; manual tool change, the tool holder from the workpiece to have enough distance from the transposition of the collision does not occur.

12. Processing process, such as the emergence of abnormal crisis situation can press the "emergency stop" button to ensure personal and equipment safety.

13, do not allow the use of compressed air to clean the machine, electrical cabinet and NC unit.

Two, the work of the preparatory work before

l, the machine tool work before the start of work to have a warm-up, carefully check whether the lubrication system is working properly, such as the machine tool for a long time not started, you can first manually lubricate the parts of the oil supply;

2, the use of cutting tools should be in line with the specifications of the machine tool allows, there is a serious breakage of the tool should be replaced in a timely manner;

3

3, adjust the tools used in the tool should not be forgotten in the machine tool;

4, the center hole of the large size shaft parts is appropriate, the center hole, such as too small, the work of the danger prone to occur;

5, the tool should be installed after the first and second trial cutting.

6, check the status of the chuck clamping work;

7, the machine tool must be closed before starting the machine guard door.

Three, the work process of safety precautions

l, prohibit hand contact with the tip of the knife and iron filings, iron filings must be used to clean up iron hooks or brushes;

2, prohibit the use of hands or any other way to contact the rotating spindle, the workpiece or other parts of the movement;

3, prohibit the amount of work in the process of machining, variable speed, and can not be wiped with a cotton wool workpiece, and can not sweep the machine;

3, prohibit processing of live, variable speed, and can not use cotton wool wipe workpiece

4, lathe operation, the operator is not allowed to leave his post, the machine tool found abnormal phenomena immediately stop;

5, often check the bearing temperature, too high should find the relevant personnel to carry out inspections;

6, in the process of machining, is not allowed to open the machine tool door;

7, strict compliance with the job responsibility system, the machine tool by the special person Use, others must be used by my consent;

8, the workpiece extends beyond the lathe 100mm, must be set up in the extended position of the guard.

Four, after the completion of the work of the notes

l, remove chips, wipe the machine tool, the use of machine tools and the environment to maintain a clean state;

2, pay attention to the inspection or replacement of wear and tear of the machine tool rail on the oil inspection plate;

3, check the state of lubricating oil, coolant, add or replace it in a timely manner;

4, turn off the machine tool operating panel on the power supply and the main power in turn. panel of the power supply and the total power supply.

5, the machine should follow the first zero (except for special requirements), manual, point, automatic principle. Machine operation should follow the principle of low speed, medium speed, and then high speed, of which the low-speed, medium-speed running time should not be less than 2-3 minutes. When it is determined that there is no abnormal situation, before starting work.

7, it is strictly prohibited in the chuck, the top of the top knocking, straightening and correction of the workpiece, must confirm the workpiece and tool clamping before the next step.

8, the operator must stop when changing tools, workpiece, adjusting the workpiece or leaving the machine while working.

9, the machine on the insurance and safety guards, the operator shall not be arbitrarily disassembled and moved.

10, the machine tool must be used before the start of processing program verification to check whether the program used with the parts to be processed, to be sure that there is no error before closing the safety shield, start the machine tool for parts processing.

11, machine tool accessories and gauges, tools should be properly stored to maintain integrity and good, lost or damaged at the price of compensation.

12, practical training should be cleaned after the completion of the machine, keep clean, the tailstock and drag plate to the end of the bed position, and cut off the machine power.

13, the machine tool in the work of failure or abnormal phenomenon should immediately stop, protect the scene, and immediately report the site responsible.

14, the operator is strictly prohibited to modify the machine parameters. If necessary, must notify the equipment manager, please equipment manager to modify.

15, understand the technical requirements of the parts drawing, check the blank size and shape for defects. Choose a reasonable method of installing parts.

16, correctly select CNC turning tools, install parts and tools to ensure accurate and firm.

17, understand and master the CNC machine control and operation panel and its operation essentials, the program accurately into the system, and simulation check, test cutting, and do a good job of all the preparatory work before processing.

18, processing process, if you find the lathe running sound is not normal or faults, stop immediately to check and report to the instructor to avoid danger.
