How to cut 400 mm thick steel plate?

400 mm steel plate cutting can be used in the following ways:
Mechanical cutting:
Cutting steel plate with tool has the advantages of simple operation, high efficiency and low cost.
Tool selection should be determined according to the material and thickness of the steel plate to ensure cutting efficiency and accuracy.
The cutting speed and feed speed should be determined according to the parameters of the tool and the material of the steel plate to ensure the cutting quality and efficiency.
In the cutting process, iron filings and debris should be cleaned in time to avoid affecting the cutting quality and tool life.

Plasma cutting:
The cutting of steel plate by high temperature ion beam has the advantages of fast cutting speed, high precision and smooth cutting surface.
The power density of the plasma beam should be determined according to the material and thickness of the steel plate to ensure cutting efficiency and accuracy.
The cutting speed and feed speed should be determined according to the parameters of the plasma beam and the material of the steel plate to ensure the cutting quality and efficiency.

Laser cutting:
Using high power laser beam to cut steel plate has the advantages of fast cutting speed, high precision and smooth cutting surface.
The laser power density should be determined according to the material and thickness of the steel plate to ensure cutting efficiency and accuracy.
The cutting speed and feed speed should be determined according to the parameters of the laser beam and the material of the steel plate to ensure the cutting quality and efficiency.

Water cutting:
For steel plate materials that cannot be cut by flame, you can try to use water cutting for processing.
The processing cost of water cutting is relatively low, and it is suitable for cutting ultra-thick steel plates.

Flame cutting:
Flame cutting is suitable for cutting thicker steel plates, but preheating is required before cutting to speed up the cutting speed.
During the flame cutting process, it should be ensured that the distance between the torch and the metal surface to be cut is consistent to ensure the cutting quality.

In the cutting process, no matter which method is used, you should pay attention to safe operation and follow the relevant operating procedures to ensure the safety of personnel and equipment. At the same time, according to the material and thickness of the steel plate, the appropriate cutting method and parameters are selected to achieve the best cutting effect.
