EGM450 CNC Universal Internal Grinder

Model ID：EGM450

High speed box type dressing.
With EGM high speed box type dressing function, it drastically reduces the wheel dressing time.
This function allows the operator to input the specifications of the dresser and the geometric data of the profile to create the optimal dressing path.
