Gundrilling procedure for lathe and machining centerWhen using a gundrill on a Lathe machine or Machining center, a short drill should be used for gundrilling a guide hole. This short hole will guide the gundrill as it enters.
Note: When drilling steel with M type head, 20 - 50% higher feed can be applied.
The depth of guide hole should be 2 - 3 times of gundrill diameter.(Read Note)
Stop the rotation of TungGun
➀ Drill the guide hole
➁ Mounting the TungGun
➂ Feed to insert the gundrill into the guide hole whilst supplying coolant to the hole. Stop the feed several millimeters above the bottom of guide hole
➃ "On" cutting rotation
➄ "On" cutting feed
Operation
CautionGundrill should NOT be in rotating condition outside the Hole.Note:
The guide hole diameter is very important when deep drilling. Accuracy of the guide hole infl uences accuracy of gundrilling hole.
AllowanceRecommendationHigh accuracy
: +50 µm: +10 - 30 µm: +3 - 10 µm
➅ Complete the gundrilling
➆ Retract
➇ Stop at the inserted position as shown in left fi gure
➈ "Turn off" cutting rotation and coolant supply
➉ Pull gundrill from the workpiece and return to zero position
