Deep hole gun barrel drilling was initially applied to gun barrels (commonly known as deep hole tube, gun barrels are not made from seamless precision tubes, the precision tube production process is simply unable to meet the accuracy requirements.) Manufacturing is thus named gun drill. With the continuous development of science and technology and the unremitting efforts of deep hole machining system manufacturers, deep hole machining has become a convenient and efficient way of processing. And is widely used in such fields as: automotive industry, aerospace industry, structural building industry, medical device industry, mold/tooling/jig industry and hydraulic and pneumatic industry.
Gun drilling is the ideal solution for deep hole machining, the use of gun drilling can obtain precision machining results, machined out of the hole position is accurate, straightness, coaxiality, and has a high surface finish and repeatability. It can easily process various forms of deep holes, and it is also a good solution for special deep holes, such as cross holes, blind holes and flat bottom blind holes.
