Spark & Co Logo


Increase productivity with the best auto threading system on the market today: with an annealing length of over 21 inches, the MV2400-ST Advance Type M800 Wire EDM can submerge cut up to 16.5 inches deep and thread the maximum workpiece height, both at the start point and through the gap if needed for broken wire recovery. To this add Mitsubishi’s highly reliable non-contact Cylindrical Drive System and M800 series control with a 19-inch touchscreen for easy operation.
