This series machine is mainly for processing ship diesel engine cylinder head coolant passages and heat resistant block milling and the development of high precision, high soft CNC machine tools, to fill gaps in the domestic similar products, machine tool using the gun drill and spray and suction drilling drilling process, to carry out work on the deep hole drilling cutting processing. Machine for double processing unit structure, a card can be installed to meet the processing requirements of different processes, improve production efficiency. The machine tool is used in the machine tool's axial, radial machining unit and the A axis to share the fixture with the servo motor drive, which has a high flexibility, easy to change.
