Deep hole strong boring machine is suitable for honing and rough boring of cylindrical deep hole workpieces, such as various hydraulic cylinders, cylinders and other precision pipe fittings. It is especially suitable for honing and polishing workpieces with step holes. The machining aperture accuracy can reach it7-it8 or above, and the surface roughness can reach ra0.2-0.4 μ M. By using local honing, the errors of taper, Ovality and local hole diameter can be corrected. For some cold drawn steel pipes, strong honing can be carried out directly. Equipped with special boring head, it can be used for boring. Deep hole boring mill is an ideal equipment with high precision and high efficiency.
  The honing box of the machine tool adopts stepless speed regulation. Gear and rack are used to drive the grinding box to realize the reciprocating motion of honing head, and the honing position can be controlled. At the same time, the double linear guide rail is adopted, which has high service life and high precision. The honing head adopts hydraulic constant pressure expansion, and the honing force of the sand bar is stable, so as to ensure the roundness and cylindricity of the workpiece. The honing pressure can be adjusted as required. Other configurations of machine tools, such as: hydraulic valve, automatic lubrication station, etc., are brand-name products.
