The ancients said that if workers want to do good things, they must first sharpen their tools. When it comes to the social clock of today, this sentence is still a famous saying. The ancients do not deceive me. The society is always changing, and the same is true for the cutting machine industry. Details:/ Molecular Sieve Filling Machine

In the cutting process, the customer often encounters cutting with different thicknesses. Different cutting speeds, cutting gas pressures, and different cutting nozzle types should be used for different thicknesses of sheet metal. Sheets with a thickness of 6-20 mm are subject to thermal variability. It is not easy to cut into the edge of the steel plate when cutting the part, but the edge of the steel plate should be closed by the perforation cutting method, and the edge of the steel plate is preferably kept at a certain distance, so that the part caused by thermal denaturation can be prevented. Size deviation problem.
For the 20-100mm plate, because cutting is not easy to change and piercing operation is easy to block the cutting nozzle, this situation is easy to cut from the edge of the steel plate, the vertical plane of the cutting surface is often insufficient when the plate is CNC automatic gas cutting. The problem of quality is mainly to guarantee the leveling of the header and the flatness of the cut sheet.
We, Kunshan Lieneng Automation Equipment Co., Ltd. hereby invite all major companies to discuss the flame cutting machine to join us.
1. The surface of each steel plate to be cut must be smooth and clean, allowing slight rust marks.
2. The gap between the steel plates (usually should not exceed 0.5mm) has a great influence on the cutting quality and the degree of slag at the lower edge of the cut. When the cutting surface roughness requirement is less than 50μm, the gap should be controlled within 0.1mm.
3, when the total thickness of the laminated board is relatively large, in order to facilitate the cut, each side of the board should be slightly extended, depending on the circumstances. In this way, the actual cutting thickness gradually increases, which helps to ensure the cutting quality. If it is necessary to start cutting from the inside of the plate, pre-drill the hole and cut it from the hole.
4. In order to ensure the quality of the cut parts, a thin plate can be placed on the top surface of the stack as a process plate.
5. The cutting nozzle uses a gas-propane diffusion cutting nozzle with a cutting oxygen pressure of 0.69 MPa. The cutting air aperture is selected as follows:
a. When the total thickness of laminated plates is ≤30mm, the cutting capacity of the cutting nozzle should be greater than 10% of the total thickness;
b. When the total thickness of laminated plates is ≤ 50mm, the cutting capacity of the cutting nozzle should be greater than 80% to 90% of the total thickness (for example, the total thickness is 60mm, and a cutting nozzle capable of cutting a thickness of 110mm should be used).
6, increase the preheating flame power, but the flame should use a slight carbonization flame.
7. The cutting speed should be about 5% slower than the cutting speed of a single thickness plate.
The Chinese cutting machine has a long way to go, and we must rely on us all to break through. Details:/
