The gun drill is an effective deep hole machining tool that can process a wide range of materials, from mold steel, fiberglass, Teflon and other plastics, to deep hole machining of high-strength alloys such as P20 and inconel. In the machining of deep hole with strict tolerance and surface roughness, gun drilling can ensure the dimensional accuracy, position accuracy and straightness of the hole.

It is necessary to master the performance of the gun drilling system (including cutting tools, machine tools, fixtures, accessories, workpieces, control units, coolants and operating procedures) in order to achieve satisfactory results in machining deep holes with gun drilling. The skill level of the operator is also important. According to the structure of the workpiece and the hardness of the workpiece material as well as the working conditions and quality requirements of the deep-hole machining machine, select the appropriate cutting speed, feed, tool geometric parameters, hard coolant parameters, in order to obtain excellent machining performance.
