S 325

CMAX S325 are Advanced CNC type of sinker edm machines. It features with 3D Mode motion machining. The oil tank capacity is up to 350 liter. The oil tank of this model is designed underneath of the machine body, where allows it to fit into facilities with limited floor space and working areas. The 6 axes are controllable with C, A, B axes which are optional electrode head. Moreover, it can be connected with robot hand, allow to change the electrodes by the robot hand. The work table is 650 x 350mm, suitable for working on small workpiece and mould, such as: electrical components, mobile phones housing and etc.
