gun drilling
Gun drilling is a really intricate operation for machining that has been put in place to facilitate the drilling of deep, dead-straight, and completely accurate holes in metal components. Gun drilling is a special operation that depends on a long, thin drill bit containing internal coolant channels. This is to enable the drill bit to remove material while maintaining its alignment. A process originally developed for making firearms barrels, it is now widely applicable across other industries.
Key Features:
- Drilling: A hollow drill bit, fed through the system coolant, removes the chips and causes heat reduction. Encouraging the capability of high depth-to-diameter ratios with very high geometrical accuracies. Smooth entry and exit on burr-free holes with less final secondary finishing having been done.
- Enhanced Properties: Improves the dimensional accuracy and straightness of holes. An improvement from thermal distortion due to constant flow of coolant. Permits precision deep-hole drilling in hard metals.
- Common Applications: Drilling rifle and pistol barrels are used in firearms manufacturing. Crankshafts, fuel injectors, and landing gear components are used in the automotive and aerospace industries. The medical industry produces surgical instruments and implants for orthopedics.
Gun drilling will have applications in high-precision manufacturing requirements for deep and accurate holes, having tight tolerances. Efficiency and reliability thus make it a crucial process in contemporary metalworking.
