Problems solved by technology

In recent years, the manufacturing technology of domestic deep hole processing machine tools has been developed by leaps and bounds, and the supporting tool (deep hole processing gun drill), due to the slender gun drill rod (diameter 3mm-40mm, length 500mm-3000mm) , Under service conditions, it is required to have extremely high strength and toughness, and the processing hole diameters are various, and the manufacturing process is difficult to standardize; and the materials used in imported gun drill pipes are produced by domestic manufacturers due to various specifications, low consumption, and cost. The mechanical properties of the drill pipe produced by the traditional process cannot meet the basic performance requirements of the parts; the heat treatment and straightening process can achieve the mechanical properties required by the parts and meet the technical requirements under service conditions, and the heat treatment deformation is absolute
Since the gun shaft is a special-shaped and slender part, a large amount of manpower and material resources are required to straighten it after heat treatment, and the straightness of the manual straightening gun shaft cannot meet the technical requirements of the design at all.
Therefore, at present, cutting tools basically rely on imports, and it is difficult to reduce processing costs and improve processing efficiency
