49 Squares

Each of the 49 squares was machined with one new copper electrode.
The ATC was used to change the electrodes automatically.
Each electrode was measured on the machine before using it.
The purpose of this test was to match all EDM surfaces with the ground frame.
The result shows the stability of the machine in unmanned operation

Equipped with Makino's superiour temperature stability, the EDAF premium Sinker EDM series do not need to leave a safety stock. The operator can program directly down to the desired depth. This is a game changer when it comes to automation!
