T2280 deep hole boring machine

This machine is the changing tpe on the basis of original deep hole machine, in addition to all the original festures of deep hole boring machine, with CNC to control turming cylindrical. This machine tool is a specially processing round work-pieces equipment, the bed with good rigidty and precision keeping well, spindle speed in wide range, feeding system is driven by AC-servo motor, it can fits for all kinds of deep hole processing needs. The oil grant adopts spindle structure, it fastening and pull-up work-piece adopts turdo and mechanical device.
The machine’s boring mode adopts pushing-boring, boring holes uses processing method of the work-piece rotation, cutter make feeding. On row chips way, it chooses enter oil foem the end of boring bar then row chip forward, it can do rolling processing. It is suitable for mass production and small batch production, equipment display, safe and reliable.
