The gundrilling machine are built by the following parts:

Machine bed: cast by gray iron HT300, twice aging treatment.

Drill box: servo main motor to drive the main spindle, rotary speed of spindle is 5000r/min;

Headstock: Rotary speed is constant 120r/min; The spindle can move axially under the control of hydraulic system to tighten and loosen the workpiece;

Guide frame: Used for guiding the cutting tool, discharge cutting chips, supporting the drill bar. The guide sleeve is assembled on its front end, used for guiding the cutting tool; The drill bar support sleeve is assembled on its rear end, used for supporting the drill bar.

Cutting tool feeding system: servo motor driving ball screw, the cutting tool feeding speed is stepless.

Drill bar support rest: The movement between drill bar support rest and drill box is linked; The distance between drill bar support rests is equal when the drill box locates in any position.

Machine control system: FANUC/Siemens or PLC

Coolant system: Mainly composed of high pressure pump groups, chain plate chips conveyor, oil chiller, filter device and so on. The pressure adjustment knob and flow adjustment panel of the coolant system are installed on the CNC system operation station.
