ZSK2110B CNC deep-hole drilling machine adopt BTA chip removal to drill small diameter deep-hole workpieces, is very suitable for petroleum drill collar workpiece. The biggest characteristic of this machine is that: the front end of workpiece which near to the oil pressure head is clamped by double chucks and the rear end is clamped by annular steady rest. The top locking of workpiece and the fixation of oil pressure head are controlled by hydraulic system, safe and practical. The machine is mated with travel head with rotating drilling rod to suit different requirement.Special deep hole drilling machine for petroleum drill collar TS21 series
