Best Budget CNC Plasma Cutter For Cutting Metal

The main application fields of CNC Plasma Cutter are: stainless steel, cast iron, copper, aluminum and other non-ferrous metal plates, which are mainly used for plane cutting of irregular patterns. Plasma cutting machine has the advantages of simple operation, high precision, high working efficiency and low labor intensity, and is widely used in various workpieces. CNC plasma cutting machine is usually used in chemical machinery, automobile industry, general engineering machinery and other industries. For materials that are difficult to cut by traditional methods, numerical control plasma cutting machine is used. 

Features of plasma cutting

 CNC Plasma Cutter can be used for cutting various metal materials such as stainless steel, aluminum, copper, cast iron, carbon steel, etc. It not only has fast cutting speed, narrow kerf, small heat-affected zone of flat kerf, low workpiece deformation, simple operation, and significant energy saving effect. The ion cutting machine is suitable for the manufacture, installation and maintenance of various machinery and metal structures, as well as cutting, opening, digging, and beveling of middle and thin plates.

Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to locally melt (and evaporate) the metal at the incision of the workpiece, and use the momentum of the high-speed plasma to remove the molten metal to form an incision.

In summary, for the accuracy of cutting, plasma can achieve cutting accuracy within 1mm, and laser can reach within 0, 2mm. From the cost point of view, CNC Plasma Cutting machine is much cheaper than laser cutting machine. Yes, in terms of processing accuracy, plasma cutting and laser cutting are rough machining and finishing.

How Do I Cut With A Plasma Cutter?

Turn on your air compressor and start building air pressure

Open windows in your shop to help ventilate air

Clean you surrounding area and make sure there are no fire hazards

Get you metal positioned in a vice, on sawhorses, or clamped to a table.

Check to make sure the cut metal will not hit you or your plasma cord when it drops

Clean the selected cut area with a wire wheel or grinder to bare metal

Draw your cut line with metal chalk or any other marking device

Hook the ground clamp of the plasma cutter to the piece of metal that will stay stationary once the cut is made

Put on your safety equipment

Plug in your plasma cutter and plug in your air hose

Double check that your machine is receiving both power and air

Line up your body to the piece of metal so that you are furthest from the sparks, have a clear view of your cut and are safe from the piece of metal falling once its cut.

Double check that you can move the plasma torch through the full range of motion of your cut without having to reposition mid cut.

Flip down your plasma hood

Position your plasma torch slightly off the piece of metal to prevent blowback if possible (this will not be possible if you are starting a cut in the middle of a piece of metal)

Press the switch or button on your torch and make the cut using a slow smooth range of motion

Continue the cut until you hear the metal hit the floor

Let the metal cool before you pick it up off the ground (small pieces of metal tend to be a lot hotter)
