1. Plasma CNC cutting machine:
working principle:
Using compressed air as the working gas and high-temperature and high-speed plasma arc as the heat source, the metal to be cut is partially melted and the melted metal is blown away by high-speed airflow at the same time to form a narrow slit. The cutting accuracy is higher than that of flame cutting, and there is no deformation in underwater cutting.
Plasma is usually described as the fourth state of matter. We generally refer to three states, namely solid state, liquid state and gaseous state; a highly ionized hot gas composed of ions, electrons and neutrons - plasma is formed.
2. Flame CNC cutting machine:
Application principle and characteristics:
Flame cutting is to use oxygen and gas (acetylene, propane, liquefied petroleum gas, etc.) Part of the metal to be cut, the method of cutting.
The flame cutting process is essentially a process in which the cut material is burned in pure oxygen, not a melting process.
3. Roller production line (U-groove production line):

This set of production line can be widely used in the production and processing of hoisting machinery, such as U-shaped grooves and other main components. The annual processing of U-shaped grooves alone can reach 140,000 tons, which can be used for supporting processing of various construction machinery and greatly reduces its production cost.
4. Steel pretreatment:
Before processing (that is, the state of raw materials), steel is subjected to surface shot blasting to remove rust and is coated with a protective primer. Pretreatment of steel can improve the corrosion resistance of mechanical products and metal components, improve the fatigue resistance of steel plates, and prolong their service life; at the same time, it can also optimize the production state of steel surfaces, which is conducive to CNC cutting machine blanking and precision blanking.
In addition, since the shape of the steel before processing is relatively regular, it is conducive to mechanical rust removal and automatic painting. Therefore, the use of steel pretreatment can greatly improve the efficiency of cleaning work, reduce the labor intensity of cleaning work and environmental pollution.
Shot blasting is the name of a mechanical surface treatment process similar to sandblasting and shot peening. The principle is to use the motor to drive the impeller body to rotate, and rely on the centrifugal force to throw the balls (cast shot, cut shot, stainless steel shot, etc.) with a diameter of 0.2 to 3.0 to the surface of the workpiece to make the surface of the workpiece reach a certain roughness. To make the workpiece more beautiful, or change the welding tensile stress of the workpiece to compressive stress, so as to improve the service life of the workpiece.
Almost used in most fields of machinery, ship repair, auto parts, aircraft parts, gun tank surfaces, bridges, steel structures, glass, steel plates, pipes, etc.

6. CNC machining center:
CNC machining center is a kind of CNC machining machine tool with complete functions. It concentrates the functions of milling, boring, drilling, tapping and thread cutting on one device, so that it has multiple technological means.
The machining center is equipped with a tool magazine, which stores different quantities of various tools or inspection tools, which are automatically selected and replaced by the program during the machining process. This is the main difference between it and CNC milling machines and CNC boring machines.
Especially for workpieces that must use tooling and special equipment to ensure product quality and efficiency, machining centers can save tooling and special equipment.
This will save a lot of time and cost for the development and modification of new products, so that the enterprise has strong competitiveness.
Numerical control (English name: Numerical Control, abbreviation: NC) technology refers to the technology that uses digital instructions composed of numbers, characters and symbols to realize the motion control of one or more mechanical equipment. Numerical control generally uses general-purpose or special-purpose computers to realize digital program control, so numerical control is also called computerized numerical control (Computerized Numerical Control), or CNC for short. It is generally called CNC abroad, and the concept of NC is rarely used anymore.

Main working principle: high-frequency high-frequency large current flows to the heating coil (usually made of copper tube) that is wound into a ring or other shape. As a result, a strong magnetic flux with instantaneous polarity changes is generated in the coil. When a heated object such as a metal is placed in the coil, the magnetic flux will penetrate the entire heated object. In the opposite direction of the heating current inside the heated object, a The corresponding large eddy current.
Due to the resistance in the heated object, a lot of Joule heat will be generated, and the temperature of the object itself will rise rapidly. To achieve the purpose of heating all metal materials.
