Basic knowledge of CNC cutting machine

1. Definition of CNC cutting machine;

The CNC cutting machine is a machine that uses a digital program to drive the movement of the machine tool. When the machine tool moves, the randomly equipped cutting tool cuts the metal sheet according to the graphics according to the graphics drawn by the computer. This kind of mechatronics cutting machine is called CNC cutting machine.
2. Working process of CNC cutting machine
1. Draw electronic graphics (CAD) on the computer or system (industrial computer system);
2. Use the supporting software to set the electronic graphics;
3. (Single-chip computer system) transfer the set graphic code to the CNC cutting machine with a U disk;
4. The CNC cutting machine performs corresponding cutting according to the drawn and set graphics.
3. Classification of CNC cutting machines
After decades of development, CNC cutting machines have made great progress in both cutting energy and CNC control systems. The cutting energy has been developed from a single flame energy cutting to the current multiple energy sources (flame, plasma, laser, high pressure water jet) cutting method; the control system of CNC cutting machine has developed from the original simple function, complex programming and input method, and low degree of automation to a control method with complete functions, intelligence, graphics and network; the drive system has also evolved from Stepper drive, analog servo drive to today's full digital servo drive;
1. The CNC cutting machine can be divided into the following types from the cutting method:
CNC flame cutting machine, CNC plasma cutting machine, CNC fine plasma, CNC underwater plasma cutting machine, CNC high pressure water jet cutting machine, intersecting wire cutting machine, CNC straight cutting machine, laser-like cutting machine, laser cutting machine
2. The CNC cutting machine is divided into the following types from the mechanical structure:
Gantry type CNC cutting machine
Cantilever CNC cutting machine
Portable CNC Cutting Machine
Desktop CNC cutting machine
CNC intersecting wire cutting machine
The gantry CNC cutting machine is the vertical structure of the double bottom beam seat of the traditional large and medium-sized machine tools, with large span and longitudinal walking distance, suitable for large-scale plate processing.
The desktop cutting machine is developed from the engraving machine. The appearance is similar to the addition of a miniature gantry cutting machine on the workbench. This type of equipment has great advantages in the field of thin plate cutting and is widely used in advertising and automotive sheet metal industries. .
The CNC intersecting wire cutting machine is a special cutting machine with a special structure. It is specially used for cutting pipes and cylindrical profiles. At present, there are not many domestic manufacturers and the demand is not large.
Robot cutting machine is a new type of cutting machine developed abroad in recent years. The cutting gun is installed on a mechanical arm, and it is operated by a numerical control system to realize multi-axis linkage. It can process three-dimensional special-shaped workpieces and realize 3D cutting. Such equipment is technically complex and expensive. Expensive, domestic equipment mainly comes from imports.
4. Application fields of CNC cutting machine
Pressure vessels, sheet metal processing, general machinery, construction machinery, steel structures, shipbuilding, auto parts, fans, cranes, stainless steel products, iron handicrafts, bridge construction, steel molds, petrochemical machinery and other industries, the application fields are very wide.
5. Introduction to the market status of CNC cutting machine.

In developed regions of Europe and the United States, the penetration rate of CNC cutting machines for blanking (steel plate cutting) is more than 90%, while in China, it is less than 30%. The domestic market has a large space, and the development momentum is very good.

The number of CNC cutting machine production and trading companies is increasing rapidly, and the market is relatively chaotic.
In the 1970s and 1980s, all CNC cutting machines were imported, and they were expensive. The price of a single machine was basically over one million. Only a few companies could afford it and could use it.
Later, China had its own R&D and production capacity, coupled with market competition, and the price was popularized, so it gradually became popular.
Constraints: 1. Price, large one-time investment;
2. Cognition; there are not many people who understand CNC cutting machines.
