B、C-axis is equipped with a two-dimensional CNC turntable, which drives the parts to tilt and rotate. The tilt angle of the B-axis is ± 90 ° or can be extended to a maximum of ± 135 ° according to the machining requirements，achieving one-time clamping of the turbine blade to complete the machining of complex curved gas film holes.

The machine is equipped with an electrode tube support mechanism. When using small electrodes, it is beneficial for the stability and aperture consistency of discharge machining.

CNC system

Running on the Windows XP system, motion control card can achieve 6-axis linkage interpolation function. Full Chinese/English graphical user interface, user-friendly and easy to operate. Touch screen 15“, network cable interface.

Using international standard G instructions for programming, the programming method is flexible and simple, supporting the import of text files generated by customers from other methods, including the coordinates of machining hole positions.

The processing hole breaking through is automatically judged and the break depth is controlled to prevent damage to the opposite wall.

The system records the position and discharge parameters of the processed holes, depth, electrode wear, and processing time. We have also designed discharge machining and penetration process curves that can be called for viewing and analysis in the future.

ern, similar to that of a milling process, can be used to machine funnel diffuser shapes.（option）
