Development of special CNC cutting machine. CNC pipe cutting machine for cutting a variety of pipe cylinder orthogonal, skew, cross and other eccentric phase used the line hole, square hole, oval hole underwater cutting machine, and can be cut at the end of the tube line intersects with inertia . This type of equipment is widely used in the production of metal structures, electrical equipment, boilers, oil, chemicals and other industrial sectors. CNC bevel cutting machine is one of the more high-end products in the line, rotary bevel cutting function of this type of equipment to meet the welding process open different angles, different plate beveling requirements. With the development of China's shipbuilding industry, the shipyard is the first in the introduction and use of CNC plasma cutting machine. As technology advances cutting machine manufacturers, domestic and foreign shipyards have been equipped with a rotary bevel cutting function of CNC plasma cutting machine, built to meet the requirements of high-tech, high value-added ships. Plasma is heated to very high temperatures and highly ionized gas, it will arc power will be transferred to the workpiece, the workpiece is melted and high-calorie blown off, forming a plasma arc cutting working condition. Compressed air into the torch assigned by the chamber after two, that the formation of the plasma gas and secondary gas. Gas Plasma arc cutting machine plays the role of the molten metal repair, and the auxiliary gas is cooled and the various components of the torch to blow off the molten metal. Cutting power supply consists of two parts of the main circuit and control circuit, electrical principle: The main circuit includes a contactor, high leakage reactance of the three-phase power transformer, three-phase bridge rectifier, ignition coil and high frequency protection elements and other components. From high leakage reactance lead to steep the external characteristics of the power supply. The control circuit via a push button switch on the torch to complete the entire cutting process: pre-ventilation - the main circuit power supply - frequency arc - cutting - interest arc - stop.
