Deep hole gun drill has a wide range of production and processing

With the continuous progress of society and the unremitting efforts of deep hole processing system manufacturers, deep hole processing has already become a convenient and effective production method. It is widely used in industries such as automobile industry, aerospace, structural construction industry, medical device industry, die shell / NC blade / fixture industry, steam pressure, air pressure industry and so on. Deep hole gun drill is a satisfactory solution for deep hole processing. Selecting gun drill can obtain the actual effect of high-precision production and processing. The produced and processed holes have accurate position, high parallelism, high parallelism, and high surface hardness and repeatability. It can easily and quickly produce and process all kinds of shallow holes. For unique deep holes, such as cross holes, buried holes and thick bottom buried holes, it can also be handled very well.

Deep hole gun drill has a wide range of production and processing, from mold materials, glass fiber, Teflon and other plastics to deep hole processing of high toughness aluminum alloys (such as P20 and Inconel). In the deep hole processing with strict dimensional tolerance and roughness, gun drill can ensure the overall dimensional precision, part precision and parallelism of the hole. In order to achieve a satisfactory practical effect in the production and processing of deep holes with gun drill, it is necessary to flexibly use the characteristics of gun drill system software (including NC blade, NC lathe, tooling fixture, accessories, product workpiece, operation module, freezing liquid and operation process). The technical strength of the operator is also very important. According to the structure of the product workpiece, the strength of the product raw materials and the working conditions and quality regulations of the deep hole machining CNC lathe, the excellent working characteristics can be obtained by selecting reasonable cutting parameters, cutting speed, the main parameters of the geometry of the CNC blade, the model of the cemented carbide tool and the main parameters of the freezing liquid.

The key to the cutting parameters of deep hole gun drill lies in the alloy structural steel, which is limited by the wear resistance of twist drill and the speed ratio of NC lathe. Generally, the cutting amount V of gun drill is 35-70m / min; The key of cutting speed is limited by the bending stiffness and compressive strength of machining process system software (NC blade, product workpiece and NC lathe, etc.). The grinding angle of deep hole gun drill does great harm to the actual effect of internal thread quality in production and processing. However, in some places with special requirements, the length change of internal and external drilling edges of gun drill will play a guiding role in the quality of internal thread production and processing. The application can be considered in places with high surface roughness and specification precision. The surface quality of drilling is poor, the cutting amount is too low, the bearing plate is deposited and the surface layer is marked with lines. The gun drill manufacturer raises the cutting fluid with improper speed ratio, and the temperature is too high, exceeding 45 ℃. The gun drill handle is clamped on the lathe spindle, and the twist drill enters the surface of the product workpiece according to the guide hole or guide column. After entering, the distinctive structure of the drilling edge has the effect of self directivity, ensuring the drilling precision.
