About Deep hole gun drilling machine

1. Drilling method :

Gun drilling mode: Internal oil supply and external chips discharge; The cutting oil reaches the cutting edge through the rotary joint mounted on rear end of drill box spindle , inner hole of drill box spindle and inner hole of drill bar, and carries the cutting chips discharging into the guide frame through the V-shaped groove outside the drill bar, and then enters the chips conveyor.

2. Machine tool processing range

Gun drill range: 420 mm

Maximum drilling depth: 2000 mm

Workpiece OD range: 1570 mm

Customization available.
