CNC plasma cutting machine is a CNC mechanical equipment mainly used to cut metal. If we want to give full play to its maximum efficiency, we must learn how to maintain it. Today, let's learn about eight keys of portable CNC flame plasma cutting machine.

1. Assemble the cutting torch correctly

Correctly and carefully install the portable CNC flame plasma cutting machine cutting torch to ensure that all parts fit well and that the gas and cooling air flow are connected. After installation, put all parts on a clean flannelette to avoid dirt sticking to the parts. Add proper lubricating oil to the O-ring, subject to the brightening of the O-ring, and do not add more.

2. The consumable parts shall be replaced in time before they are completely damaged

Do not replace the consumable parts after they are completely damaged, because the seriously worn electrode, nozzle and vortex ring will produce uncontrollable plasma arc, which is very easy to cause serious damage to the cutting torch. Therefore, when the cutting quality is found to decline for the first time, the consumables should be checked in time.

3. Clean the connecting thread of the cutting torch

During replacement of consumable parts or daily maintenance and inspection, ensure that the internal and external threads of the cutting torch are clean. If necessary, clean or repair the connecting threads.

4. Clean the contact surface between electrode and nozzle

In many portable CNC flame plasma cutting machine cutting torches, the contact surfaces between nozzle and electrode are charged contact surfaces. If these contact surfaces are dirty, the cutting torch will not work normally and should be cleaned with hydrogen peroxide cleaning agent.

5. Check the gas and cooling gas every day

Check the flow and pressure of gas and cooling air flow every day. If insufficient flow or leakage is found, stop the machine immediately to eliminate the fault.

6. Avoid cutting torch collision and damage

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

7. The most common causes of cutting torch damage

(1) Cutting torch collision.

(2) Destructive plasma arc due to damage to consumer parts.

(3) Destructive plasma arc caused by dirt.

(4) Destructive plasma arc caused by loose parts.

8. Precautions

(1) Do not grease the portable CNC flame plasma cutting machine cutting torch.

(2) Do not overuse O-ring lubricant.

(3) Do not spray anti splash chemicals when the protective sleeve is still on the cutting torch.

(4) Do not use a manual cutting torch as a hammer.
