If you are wondering how to choose rifle boring machine, gun barrel drilling machine, deep hole gun drilling machine, multiple spindle drilling machine, if you are checking products price, or if you are looking for high-quality products for sale, please feel free to contact Golden Stone Machinery, we are one of the leading China concentric hole gun drilling machine manufacturers equipped with professional factory.

Brief Introduction：

The series of gundrilling machine is mainly for drilling concentric deep hole of small and medium sized axial parts. The series is introduced multi spindle and workpiece’s position design which can simultaneously drill multi workpiece. For fasten and convenient clamping, the clamping method is flexible according to type of workpiece , besides, clamping system is equipped with auxiliary support frame.

ZK21 series of GSM’s gun drilling machine has already served in drilling deep hole of auto parts industry, medical machinery (titanium bone screw, etc), small and medium sized axial parts of textile industry, etc. Additionally, the series of gun drilling machine has reliable performance in drilling precise shallow hole.
