Machine Description
1.Four CNC axis control
2.Drilling on three sides of H-beam Simultaneously
3.Direct conversion between CAD and CAM is available.
4.Ideal equipment used for stereo garage steel structure processing.
5.Roller feeding and lengthways CNC measurement are used.
6.The use of imported spray cooling system can prolong life of the drills.
7.All spindles adopt the self-controlled travel drilling head. Three different diameters of drill bits can be installed in each side to achieve high efficiency.
8.Ideal equipment used for steel structure processing
