DESCRIPTION

The 518TB machining centre are dedicated to the production of turbine blades from 30 to 250 mm in length.

These machines are the perfect solution for energy applications (gas turbines, steam turbines) and aeronautical applications (compressor stage blades and turbine blades). In order to offer manufacturers a turnkey solution, Willemin-Macodel works in close cooperation with designers on a global scale.

This has resulted in efficient solutions in the field of adaptive machining. After acquiring the geometry of the workpiece mounted to the machine, the program will calculate a new toolpath matching the theoretical points with the probed points. This method has been specifically adapted for forged or precision cast pieces with very finely machined surfaces and for secondary operation.

Benefiting from the latest technological developments and willemin-macodel's comprehensive expertise in high-precision machining, the 518TB is perfect for cutting-edge industries such as aeronautics and high-precision mechanical sub-contracting.
