Deep hole gun drill is also called deep hole drill. It was originally used in weapon manufacturing industry, so it is named gun drill. With the continuous development of science and technology, deep hole processing system manufacturers' unremitting efforts, deep hole processing has become a convenient and efficient processing method. It is widely used in such fields as automobile industry, aerospace industry, structural construction industry, medical equipment industry, mold, cutter, fixture industry, oil pressure, air pressure industry, etc.
Gun drill is an ideal solution for deep hole processing. Using gun drill can obtain precise processing effect. The processed hole position is accurate, with high straightness and coaxiality, high surface finish and small deviation. It can process all kinds of deep holes conveniently. In practical application, the technology of drilling before reaming can be replaced by one-time processing, and it has strong process reliability.
Gun drill can drill cast iron, carbon steel, copper, aluminum alloy, alloy steel, etc. it can complete drilling, boring and reaming once, and can process high precision (it8-11 grade), precision straightness (0.16-0.5mm / 1000mm) and low roughness (ra6.3-ra0.8) holes once cutting. The drilling line speed is over 30-100m / min.
Gun drill is mainly used to drill the hole diameter, with the range greater than 1.5mm-38mm. The length diameter ratio of drilling refers to: drill diameter x 150 times. (that is, the maximum drilling depth), the high-pressure coolant reaches the cutting position through the spindle and the center of the drill bit. The scrap iron is discharged through the V-groove on the drill.
