Machine brief:

   Gun drilling machine is a machine tool for deep hole drilling process,its sructure has big difference with traditional drilling machines,which has its unique design. The drilling depth could be 100times of the job diameter,if customer has special requirements,by taking specially measure,the drilling depth could realize 200times of its diameter. In additional,the roughness of the inner hole after drilled is in high level,hole size accuracy could be IT7,roughness could be Ra6.3-Ra0.4um,linear accuracy could be 0.1/1000mm. Due to these characters,nowadays,gundrilling machine is not only used for deep hole,it also replaced the reaming,expanding process,and one time drilling,it could solve drilling,expanding and reaming process.

   Needs three conditions to get good results for gundrilling process, 

1. Good quality gundrills. 2. Machine specially made according to requirements. 3.Suitable cutting liquid

   
   

Gundrilling maximum depth：500/1000/1500/2000/2500 mm/3000mm/4000mm

Hole maximum length and diameter ratio: 100:1(special request needs to special designed
