From the perspective of the processing principle of steel plate cutting, the focus of steel plate cutting is divided into two categories, one is hot processing and the other is cold processing. Thermal processing is the most ordinary steel plate cutting method. Because of its fast cutting speed, large thickness, and various complicated pattern cutting, it is efficiently and commonly used in various mechanical processing industries such as flame cutting, plasma cutting, laser cutting, grinding wheel cutting, etc. belong to the category of metal thermal processing.
Cold working is very meaningful. It refers to the low heat and small thermal deformation in the process of steel plate cutting. Water cutting, wire cutting, etc. belong to the boundary of cold working!
From the topography of steel plate cutting, this chapter focuses on some cutting equipment for thermal processing! In terms of processing accuracy, laser cutting in thermal processing is the most accurate, but it has low efficiency and high cost. Only a small number of large enterprises and high-precision cutting boundaries can be used in ordinary ways. Nowadays, the most important cutting methods used in shopping malls are CNC flame cutting and CNC plasma cutting.
CNC flame cutting is suitable for cutting 6-300mm carbon steel material. It has a large cutting thickness, high efficiency, no bevel, and easy to use. The materials used for cutting are mainly oxygen and cutting gas. Low cost and most common in all kinds of metal cutting processes!
Plasma cutting is used in some stainless steels, and relative to the cutting of some metal steel plates ≤40mm, the cutting speed is fast, and the cutting dedicated to non-ferrous metals is its biggest feature! However, inspection smoke and dust will occur during the cutting process, but with its fast cutting performance and plasma beveling performance, it is also used in market conditions.
