The 3D printing department of the company completed the blade printing

Blade is an important component of turbine section in gas turbine engine. High-speed rotating blades are responsible for drawing high temperature and high pressure air into the burner to keep the engine working. In order to ensure stable and long-term operation in extreme environments of high temperature and pressure, turbine blades are often forged with superalloy and cooled in different ways, such as internal airflow cooling, boundary layer cooling, or thermal barrier coating to protect blades, etc., to ensure reliability during operation.Titanium alloy is a medium strength α-β type two phase titanium alloy containing 6%α stable element Al and 4%β stable element V. The alloy has excellent comprehensive properties and has been widely used in the aviation and aerospace industry.However, due to the poor thermal conductivity of titanium alloy, high chemical activity, the temperature at the tool tip increases quickly when cutting, which is easy to cause tool wear processing difficulty. At present, the production cycle is greatly shortened by 3D printing and precision machining combined with the traditional four and five axis machining center.

Guangzhou Sailong completes the overall production and processing of blades through in-depth cooperation with customers in related industries, and controls the processing allowance of printed rough parts according to the adjustment of equipment precision, and then the customers finish the production of final products by precision machining.
