What is common sense in steel plate processing?

We often in the steel plate processing or cutting, what equipment is used for the processing of unusually hard steel, the general use of equipment are: CNC cutting machine, laser cutting machine, shearing machine and other advanced processing equipment.
The general types of steel plate processing are: coil plate, open plate, medium thick steel plate, extra thick steel plate, manganese steel plate and 45 steel plate, etc.

For CNC machine tools, the speed of steel plate processing can not be too fast, as slow as possible, for water knife cutting machine, the use of water-soluble cutting fluid coolant, is semi-synthetic, because it is more good whether it is cooling or lubrication effect.

There is also in the process of steel plate processing, some need to weld links, we must pay attention to the size of the welding machine current.
In the process of steel plate processing, the surface of the cutting machine will be combined with other materials to form alloy materials, which makes the props easy to rust, if possible, try to add an anti-oxidation film or anti-oxidation film to it.
