Piston irregular outer circle double-head lathe
- Commodity name: Piston irregular outer circle double-head lathe
- Product Description
-
Machine Tool Structural Features:This machine tool uses an integrally cast bed, ensuring stability and rigidity, and providing good shock resistance. The bed is designed with a 45º inclination for smooth chip removal during machining, while also offering the advantages of a horizontal bed and tool rest for bearing cutting forces.This machine tool is equipped with high-precision linear guides and high-precision ball screws, offering good wear resistance and long-term accuracy retention. P4 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/hydrodynamic 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 variable frequency controlled at 400-3000 rpm.This machine tool system uses a PTC-5 control system. Compared to hard dies, its features include: fast response, high precision, simple operation, and the ability to flexibly adapt to different piston profile requirements.This machine tool is suitable for machining the outer circle of irregular aluminum alloy pistons. The maximum machining of single-sided ellipse + profile is 1.4mm, the surface roughness is Ra1.6, the piston size error is ≤0.005mm, and the profile and ellipticity contour error is ≤±0.003mm.Main Specifications:
