However,for carbon steel less than 10mm thickness,we can choose 1000w or lower power machine.

Cause the cutting width is very small.The width is  from 0.1 to 0.5mm.

The cutting precision is very high,lower than 0.05mm.

And the distance between the center of the hole is between 0.1 and 0.4 mm.

The contour size error is also between 0.1 and 0.5 mm.

Cutting section is Smooth.

The roughness of the slit is less than 25μm.After the work piece is cut, we can  directly weld it without further processing.
