Relative rotational type of Precision gun drilling machine

gun drilling machine


The medical gun drilling machine is a high-precision model (internationally patented) especially developed for medical use and is particularly designed for hole diameters of φ 0.5 to 6.0, which are in high demand for medical and other types of instruments. It permits high-quality deep hole drilling. Even though the relative rotation system, its deep holes can be machined in the workpieces that have already been processed, and its maximum deep hole drilling length is 600 mm.
