How to maintain the plasma cutting machine?Thorpe
CNC plasma cutting machine is an automatic cutting equipment, suitable for cutting and perforating various non-ferrous metal sheets such as carbon steel, stainless steel, iron, aluminum, white steel, etc. Standard plasma cutting and flame cutting modes, integrated structure, bilateral drive, fast cutting speed, small inertia, and stable operation.
Assemble the torch correctly
Install the cutting torch correctly and carefully, ensure that all parts are well matched, and ensure that the gas and cooling air flow. Install all the parts on a clean flannel to avoid dirt sticking to the parts. Add proper lubricating oil to the O-ring, subject to the brightening of the O-ring, and no more.
Consumable parts should be replaced in time before they are completely damaged
Do not replace the consumable parts after they are completely damaged, because severely worn electrodes, nozzles and swirl rings will produce uncontrollable plasma arcs, which can easily cause serious damage to the cutting torch. Therefore, when the cutting quality is found to be degraded for the first time, the consumable parts should be checked in time.
Clean the connecting thread of the cutting torch
When replacing consumable parts or daily maintenance and inspection, be sure to ensure that the internal and external threads of the cutting torch are clean. If necessary, clean or repair the connecting threads.
Clean the contact surface of the electrode and the nozzle
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 will not work properly and should be cleaned with hydrogen peroxide cleaning agent.
Check gas and cooling gas daily
Check the flow and pressure of the gas and cooling air flow every day. If you find that the flow is insufficient or leaks, you should stop the machine immediately to troubleshoot.
Avoid torch collision damage
In order to avoid collision damage to the cutting torch, it should be programmed correctly to prevent the system from overrun. The installation of an anti-collision device can effectively avoid damage to the cutting torch during collision.
The most common causes of torch damage
(1) The cutting torch collides.
(2) Destructive plasma arc caused by damage to consumables.
(3) Destructive plasma arc caused by dirt.
(4) Destructive plasma arc caused by loose parts.
(1) Do not apply grease on the cutting torch.
(2) Do not overuse O-ring lubricant.
(3) Do not spray anti-splash chemicals while the protective cover is still on the cutting torch.
(4) Do not use the manual cutting torch as a hammer.
