What’s the best CNC plasma cutting machine

What is portable plasma cutter?

CNC plasma cutting machine is a kind of advanced mechatronics equipment used for blanking and cutting of sheet metal. It has been widely used in shipbuilding and machinery manufacturing industries. There are many factors that affect the cutting quality of CNC plasma cutting machines. In addition to the design parameters of the cutting machine, they are also related to the operation control and cutting process. In order to improve the cutting quality, we carried out a comprehensive cutting test, analyzed and arranged according to the test data, and obtained some of the best working parameters of the CNC plasma cutting machine.

A high-quality cutting surface should have an inclination of less than 30, a cutting pattern depth of less than O.15mm, and less dross, which is easy to remove.

In the condition of stable voltage and current, in addition to the quality of the electrode and the nozzle, the factors affecting the cutting quality have two reasons:

  1. Cutting nozzle height and stability;
  2. Matching of cutting speed and working air pressure

When the height of the cutting nozzle from the steel plate is controlled by an arc pressure height adjuster, its dynamic positioning accuracy can reach ± 0.013, so it can ensure that the height of the cutting nozzle and the steel plate remains unchanged, so the cutting surface has a small and uniform inclination , And the finish is good.

When manually adjusting the height of the cutting nozzle from the steel plate. The cut steel plate should be leveled as far as possible to reduce the adjustment times of the cutting torch.

Ensure the stability of the cutting torch. In this paper, the height of the cutting nozzle from the steel plate is controlled by 6 ~ 8mm by manual adjustment. Through a series of cutting experiments, the relationship between cutting speed (dirty), working pressure (P) and cutting quality is explained.

How to choose best plasma cutting machine

Many people admire the speed of plasma cutting. In order to improve the processing capacity of the factory, they decided to purchase advanced CNC cutting equipment.

For example, a friend is going to purchase a portable plasma cutting machine, and requires the CNC cutting machine to purchase together with the plasma power supply. Since the processing range of the customer is to the 15mm thick steel plate with the width of 1500mm, and it can not be guaranteed that it is always cut from the edge in use, some graphic processing is easy to use perforation cutting, so if the customer is configured with 120a plasma The cutting effect is not ideal. But if we want to choose 160A plasma, the purchase cost will rise a lot. In the face of such confusion, where should customers go?

Understand that the customer’s actual use is mainly to cut carbon steel parts. Because the customer’s processing width is 1500mm, in order to fully meet the demand and better cut parts, the customer chooses 1600mm portable cutting machine, which is changed from the original plasma cutting machine to flame plasma dual-purpose integrated machine. When the customer processes 12mm and below thick plates, he directly uses 120 plasma for cutting Cutting, when customers cut 15mm or even thicker carbon steel, we use our flame cutting method directly.

Such a solution not only fully meets the initial needs of customers, but also has been upgraded to a higher processing standard. But in terms of the overall purchase cost, it saved more than 10000 yuan.

How to use the manual / automatic plasma cutting machine

Plasma cutting machine advantage


  1. Can cut various complicated workpieces
  2. fast cutting speed, high efficiency, good cutting surface quality, accurate cutting size, small thermal deformation of the workpiece
  3. The cut parts can be directly welded and applied without mechanical processing.

Plasma cutting machine disadvantages

  1. The inclination of the cutting surface is large
  2. The finish is not as good as oxygen cutting
Manual non-contact cutting

(1) Touch the torch roller to the workpiece, and adjust the distance between the nozzle and the plane of the workpiece to 3 ~ 5mm. (When the host machine cuts, the “Cut Thickness Selection” switch is turned to *).
(2) Turn on the torch switch to ignite the plasma arc. After cutting through the workpiece, move it in the cutting direction at an even speed. Too slow will affect the quality of the incision, and even break the arc.
(3) After cutting, turn off the torch switch and the plasma arc goes out. At this time, compressed air is sprayed out at a delay to cool the torch. After a few seconds, the ejection stops automatically. Remove the cutting torch to complete the entire cutting process.

When manual contact cutting

(1) The “Cut Thickness Selection” switch is at the low level, which is used when the single machine cuts thinner plates.
(2) Place the cutting torch nozzle at the starting point of the workpiece to be cut, turn on the cutting torch switch, ignite the plasma arc, cut through the workpiece, and then move uniformly along the cutting direction.
(3) After cutting, open and close the torch switch. At this time, the compressed air is still spraying. After a few seconds, the cutting machine will automatically stop spraying. Remove the cutting torch to complete the entire cutting process.

Automatic cutting

(1) Automatic cutting is mainly suitable for cutting thick workpieces. Select the “Cut Thickness Selection” switch position.
(2) After removing the cutting torch roller, the cutting torch and the semi-automatic cutting machine are firmly connected, and the attachment is provided in the random accessories.
(3) Connect the power of the semi-automatic cutting machine, and install the guide rail or radius rod according to the shape of the workpiece (if it is a linear cutting rail, if you are cutting a circle or arc, you should choose a radius rod).
(4) If the torch switch plug is turned off, replace the remote switch plug (prepared in the accessories).
(5) Adjust the appropriate walking speed according to the thickness of the workpiece. And set the “up” and “down” switches on the semi-automatic cutting machine to the cutting direction.
(6) Adjust the distance between the nozzle and the workpiece to 3 ~ 8mm, and adjust the center position of the nozzle to the starting strip of the workpiece slit.
(7) Turn on the remote control switch. After cutting through the workpiece, turn on the power switch of the semi-automatic cutting machine to cut. In the initial stage of cutting, pay attention to the cutting seam at any time and adjust to a suitable cutting speed. And pay attention to whether the two machines work normally at any time.
(8) After cutting, turn off the remote control switch and the power switch of the semi-automatic cutting machine. At this point, the entire cutting process is completed.
