CNC plasma cutting machine is the main cutting equipment for cutting smaller workpieces today. At the same time, it can also cut softer materials such as non-ferrous metals that cannot be cut by flame cutting machines. Maintenance of CNC plasma cutting machines is also indispensable, because its work The environment is not very good, so if you want to ensure that it can be used for a long time and ensure the cutting accuracy, you need to do safe operation and correct maintenance. For your reference.

1. Maintenance of CNC plasma cutting machine

1. Install the torch correctly and carefully, ensure that all parts are well matched, and ensure the circulation of gas and cooling gas. Installation Put all parts on a clean flannel to prevent dirt from sticking to the parts.

2. Do not replace the consumable parts after they are completely damaged, because the severely worn electrodes, nozzles and eddy current rings will generate uncontrollable plasma arcs, which can easily cause serious damage to the cutting torch. Therefore, when the cutting quality is found to be degraded, the consumables should be checked in time.

3. When replacing consumables or daily maintenance and inspection, be sure to ensure that the inner and outer threads of the cutting torch are clean, and if necessary, the connecting threads should be cleaned or repaired.

4. In many cutting torches, the contact surface between the nozzle and the electrode is a charged contact surface. If these contact surfaces are dirty, the cutting torch cannot work normally.

5. Check the flow and pressure of the gas and cooling airflow every day. If you find that the flow is insufficient or there is a leak, you should immediately stop the machine to troubleshoot.

6. In order to avoid the collision and damage of the cutting torch, it should be programmed correctly to avoid the system from overrunning, and the installation of the anti-collision device can effectively avoid the damage of the cutting torch during collision.

In addition to daily maintenance, in order to reduce the wear and accidental damage of the CNC plasma cutting machine, it is necessary for the staff to perform correct and safe operation, which is not only responsible for the equipment, but also for the personal safety of the staff. The way is as follows:

1. Operators must wear protective masks, welding gloves, hats, filter dust masks and soundproof earmuffs. Personnel without protective goggles are strictly prohibited from directly observing the plasma arc, and bare skin is strictly prohibited from approaching the plasma arc.

2. When cutting, the operator should stand on the upper wind to operate. The air can be drawn from the lower part of the workbench, and the open area on the workbench should be reduced.

3. When cutting, when the no-load voltage is too high, check the electrical grounding, zero connection and the insulation of the torch handle, insulate the worktable from the ground, or install a no-load circuit breaker in the electrical control system.

4. The high-frequency generator should be equipped with a shielding shield, and the high-frequency circuit should be cut off immediately after the high-frequency arc is used.

5. The use of thorium and tungsten electrodes should comply with the safety operation regulations of relevant documents.

6. The cutting operation and cooperating personnel must wear labor protection equipment as required. Safety measures must be taken to prevent accidents such as electric shock, falling from heights, gas poisoning and fire.

7. The electric welding machine used on site shall be equipped with a machine shed to prevent rain, moisture and sun, and shall be equipped with corresponding fire fighting equipment.

8. Safety belts must be fastened when welding or cutting at high altitudes. Fire prevention measures should be taken around and below the welding and cutting, and special personnel should be supervised.
