ZK2135E/2500 Deep Hole Drilling Machine With Rotating And CNC Indexing Function Of Workpiece Main Spindle

ZK2135E/2500 deep hole drilling machine is designed to be horizontally arranged. The host body is divided into the left part and as workpiece clamping and the right part as drill stem feeding system. The end face is coupled with the screws and pins. Hydraulic chuck and hydraulic center frame are used to clamp workpiece. The basic parts of machine are HT300 precise cast. Ball screw and rolling guide are used for drill stem feeding.

Features
