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.
