Gun Drilling Machine

CBR-800SNC/CBR-1000SNC

CBR-1200NC/CBR-1500NC/CBR-1800NC

It fits in working big workpieces of molding drillilng field and fits in column NC drilling. The working table can take heavy weight and big size of mold and it is suitable for making the cooling holes and pin holes in the mold.
The spindle is stepless when the gundrilling is working and it is the most efficiency machine to work on it.
You can work on the same workpiece with different deep holes. It is functional to work not only on one workpiece but also many workpieces.
The NC design can maintain the workpiece in high accuracy, even under no one's control.
