In cutting, the most widely used method is to use plate shears, which are suitable for ordinary carbon steel and stainless steel. The stainless steel cutting tools are made of high-speed tool steel. To obtain a smooth edge, the cutting surface of the tool should be sharp and free from burrs.

Stainless steel plate, especially austenitic stainless steel, has higher ductility, so when cutting, it is necessary to reduce the gap of the cutter, ensure that the cutting is bright, and do not make the stainless steel produce plastic deformation or pull down the cover cutter. Before the fracture occurs, the cutting tool should just cut to half of the plate thickness, and the allowance at this time is more suitable. Excessive tool allowance will lead to tool damage, and there will be very large burr on the edge of the steel plate to be cut.

In the field of metal sheet cutting, fiber laser cutting machine is undoubtedly the best cutting tool. Many metal processors choose medium and small power fiber laser cutting machine when processing thin metal plates less than 12mm, because it not only has fast cutting speed and good cutting effect, but also has very low cutting cost. However, for metal plates with different thickness, different power fiber laser cutting equipment should be selected. Specific how to choose, you can refer to the fiber laser cutting machine cutting parameters.

Cutting 0 ~ 3mm stainless steel, 0 ~ 5mm carbon steel, can choose 500W fiber laser cutting machine. If the power is lower than this, there may be continuous cutting or burr on the cutting section, which will lead to the decline of product quality and bring trouble to the sales of enterprises; if the power is too high, although the cutting effect is good, it is a bit wasteful, so it is not recommended for enterprises to choose.

When cutting 3 ~ 4mm stainless steel and 5 ~ 6mm carbon steel, you can choose 600W fiber laser cutting machine, because this power can just meet the cutting requirements of enterprises, and the cost is the lowest.

For cutting 4 ~ 6mm stainless steel and 6 ~ 10mm carbon steel, 1000W fiber laser cutting machine can be selected, especially for 6mm stainless steel plate and 10mm carbon steel plate. Only 1000W fiber laser cutting equipment can achieve effective cutting. If the power is too low, it will affect the production efficiency and damage the equipment.

Common cutting equipment:

1. Angle grinder

Angle grinder is a hand-held device for grinding and cutting. It is an ideal tool for cutting stainless steel plate. It needs side grinder to cooperate with blade. After the angle grinder and cutting wheel are set, mark and line on the incision, align the cutting wheel with the area to be cut, and slowly put it on the stainless steel plate.

2. Cutting saw

The cutting saw is a small tool, suitable for cutting thin stainless steel parts. Now there is a popular pneumatic cutting saw, which is very important for the cutting process. Need durable high speed cutting wheel.

When using this kind of equipment, to prevent the cut pieces from hurting people, first mark the position to be cut, and then slowly press the blade onto the material. Cut the steel slowly without stopping. After cutting, polish the edge with the grinding wheel to prevent cutting.

3. Circular saw

If you want to cut a large stainless steel plate, the circular saw machine is a good tool. This kind of equipment can cut a thick stainless steel plate. Use a special metal cutting blade to fix the stainless steel plate, mark the cutting position, and slowly cut into the material.

4. Band saw

The band saw is mainly used for cutting stainless steel plate, which is mainly used for pipe materials. The blade penetrates through the stainless steel plate to cut the horizontal surface. This special blade is made of tungsten carbide, and the cutting speed can be set to low level, so that the incision will be smoother.

5. Pipe cutter

The pipe cutter is mainly used for cutting stainless steel plate and pipe. When the cutter rotates, the cutting wheel gradually cuts through the pipe.

6. Plasma cutting machine

Plasma cutting machine is an ideal choice for cutting large stainless steel plate. The concentrated energy beam is used to cut thick materials. The cutting end is placed about 7cm away from the surface of stainless steel plate. When it is turned on, the steel plate will burn immediately and cut along the wire. In order to obtain good cutting effect, it is necessary to carry out linear cutting.

The cutting parameters of optical fiber laser cutting machines produced by different manufacturers are different, but the difference is not big. When purchasing equipment, metal processors can first compare the parameters of several manufacturers, and then select the most appropriate equipment, which can not only ensure the cutting effect, but also improve the production efficiency and profit of enterprises.
