As a top-manufactured aero-engine, it is a highly complex and precise thermodynamic machine. Each manufacturing process is extremely demanding and requires a wide variety of materials. The high-temperature components in it not only need to withstand scorching high temperatures, but also need to withstand high temperatures. Strong air pressure, the slightest error directly leads to the failure of the entire aircraft. Now the design and manufacture of aero-engines are very complex, covering tens of thousands to hundreds of thousands of small parts, and a large number of current titanium alloys, high-temperature gold, stainless steel and other non-metal special coatings are used. These materials not only have high specific hardness , brittle, but also has the characteristics of high melting point and low thermal conductivity. For example, the turbine blades inside are not only special in shape, but also have the characteristics of high temperature resistance. If the conventional processing method is used, the operation is not only complicated, but also the process requirements are difficult to achieve. Therefore, it is necessary to use the current high-tech means--- Laser technology laser cutting machine.
