Steel Plasma Cutting Plasma CNC Machine For Sale

What is the problem with the nozzle of the plasma cnc machine for sale?

The electrode cutting nozzle used in CNC plasma cutting needs to pay attention to the cutting nozzle's quality when buying. Because the cutting nozzle wears more frequently than the flame cutting when using plasma cutting, the cutting nozzle quality of the Steel Plasma Cutting is not good, which exacerbates the cutting nozzle during use. Loss requires special attention. It is not possible to choose poor quality electrode cutting nozzles just to save costs. Under normal circumstances, the service life of a set of electrode cutting nozzles varies from 3-4 hours.

Plasma cnc machine for sale accessories and nozzles are extremely important consumables. The cutting nozzle is a consumable part of the CNC cutting machine torch. It is normal to replace the wear and tear during use. In use, there are different degrees of reflection that there are problems such as high frequency of cutting nozzle replacement and serious wear and tear.

The material and thickness of the cutting workpiece and the arrangement of the cutting process, etc. The cutting workpiece's material consumes fewer electrode nozzles for ordinary plates, stainless steel, cast iron, and other materials.

Caused by improper use, such as the cutting nozzle is too close to the steel plate when cutting (generally 100A plasma cutting). The size of the cutting nozzle is generally not less than 3~8 mm from the steel plate), the external input voltage is too high or unstable.

Table type plasma cutting machine is in high automation and efficiency,easy operation and long service time. The plasma cutting machine is table structure with double-driven system, working size can be customized upon requirement. It can be used for cutting carbon steel, stainless steel and non-ferrous metal in any 2D graphics,this is widely used in metal cutting fields.

How does a CNC plasma cutter work?

 Plasma cutting is a machining method that uses the heat of a high-temperature plasma arc to melt at a metal workpiece, and to eliminate the molten metal by high-speed plasma momentum to create a slit. Plasma cutters send an electric arc by using gas like oxygen, nitrogen or compressed air. This turns the gas to plasma, as well as it promptly blasts through metal to cut it with broadband. A flame cutting torch works by adding a blast of oxygen to the flame which oxidizes the metal and turns it into slag. The plasma torch moves with a tool path directed by a computer. The term "CNC" means "Computer Numerical Control", which implies that a computer is used to control the motion supported G-code in a program. Compared to handheld plasma cutters, plasma CNC cutters realize automatic machining with high efficiency, high speed, and high quality. 

Maintenance and maintenance of CNC plasma cutting machine

The working site and working environment of the CNC cutting machine are relatively harsh, and the metal dust is relatively large. Therefore, the machine must be thoroughly cleaned and maintained, and a dedicated person should be responsible for the lubrication, repair, and maintenance of the equipment!

1. Safe operation:

(1) The CNC cutting machine is a kind of precision equipment, so the operation of the cutting machine must be three fixed (a fixed person, fixed machine, fixed post).

(2) The operator must be professionally trained and be able to master the essentials of the operation, non-professionals should not move.

(3) Before the operation, it must be confirmed that there is no external interference. After everything is normal, hang the cut plate on the cutting platform, and the plate cannot exceed the cutting range.

2. Daily maintenance and maintenance:

(1) The dirt on the machine tool and guide rails must be cleaned every working day to keep the machine bed clean. The air source and power supply must be turned off when off work and the remaining air in the machine tool pipe belt must be drained.

(2) If you leave the machine for a long time, turn off the power to prevent non-professional operation.

(3) Pay attention to observe whether there is lubricating oil on the surface of the machine's horizontal and longitudinal guide rails and racks to keep them well lubricated!
