The machine is special equipment for machining deep cylindrical hole of workpieces. It can be perfectly suited for boring through holes, blind and step hole in workpiece: such as, spindle of various kinds of machines, many kinds of hydraulic oil cylinders and cylinders. It can perform not only boring, but also rolling pressing. The machine is strong in rigidity of the bed, high in precision, and wide in spindle speed range. Feed system is driyen by Siemens A.C.Servo feeding motor. It is suitable for various processing methods of machining deepholes. Fixture of the guide carriage and clamping force of the workpiece are performed by hydraulic device and indicated by meter.

Various change-model products of the series can be supplied according to users requirement.
