Product description
Structural characteristics of machine tools:
  This machine adopts an integral casting bed to ensure the stability and rigidity of the machine, and has good shock resistance. The bed has a 45 ° inclined design, which facilitates the smooth chip removal during the machining process. At the same time, it has the advantage that the horizontal bed tool holder can withstand the cutting force.
  This machine is equipped with high-precision linear guide rails and high-precision ball screws, which has better wear resistance and longer accuracy retention. P4 precision paired screw bearings ensure the machine's repeatable positioning accuracy is 0.002mm ± 0.002mm.
  This machine tool uses the NP series of high-precision dynamic and static pressure spindle units. Since the spindle adopts a sliding bearing structure supported by a mixed oil film, its radial rotary runout accuracy is ≤0.001mm, and the frequency conversion speed of the spindle is adjustable from 400 to 3500 rpm.
  The tool holder system of this machine tool uses a servo tool holder control system. Compared with hard molds, its features are: fast response, high accuracy, easy operation, and can be flexibly changed to process according to the different contour requirements of the piston.
  This machine is suitable for special-shaped cylindrical machining of aluminum alloy pistons. The processing piston can process a single-sided ellipse + shape line 1.4mm, processing roughness Ra1.6, processing piston size error ≤0.005mm, profile line, ovality contour error ≤ ± 0.003mm.
