Piston eccentric external cylindrical lathe

  • Commodity name: Piston eccentric external cylindrical lathe
  • Product Description
  • Machine Tool Structural Features:
     
      This machine tool uses an integrally cast bed to ensure machine stability and rigidity, with good shock resistance. The bed is designed with a 45º inclination, facilitating smooth chip removal during machining, while also offering the advantages of a horizontal bed capable of withstanding cutting forces.
     
      This machine tool is equipped with high-precision linear guides and high-precision ball screws, providing good wear resistance and long-term accuracy retention. P4-grade precision matched screw bearings ensure the machine's mechanical repeat positioning accuracy within 0.002mm±0.002mm.
     
      This machine tool uses an NP series high-precision hydrostatic/dynamic pressure spindle unit. Because the spindle uses a hybrid oil film supported sliding bearing structure, its radial runout accuracy is ≤0.001mm, and the spindle speed is frequency-controlled and adjustable from 400~3500 rpm.
     
      This machine tool's turret system uses a servo turret control system. Compared to hard dies, its features include: fast response, high precision, easy operation, and the ability to flexibly adapt to changes based on different piston profile requirements.
     
      This machine tool is suitable for machining the outer cylindrical surface of aluminum alloy pistons. Maximum single-side ellipse + profile machining is 1.4mm, surface roughness Ra1.6, and piston dimensional error ≤0.005mm, profile and ellipticity contour error ≤±0.003mm.
