C-40S Dual-spindle turret lathe
C-40S Dual-spindle turret lathe
■ A2-5 spindle ■ Ø160+130 hydraulic chuck ■ 8-63 servo turret ■ A2-4 Sub-Spindle Taper
Features：
Dual-spindle coaxial structure maintains 0.005mm geometric tolerance. Modular design enables flexible process combinations for shaft/disc parts in single setup. Optional power turret with C-axis control allows external/face machining (turning, milling, drilling, tapping) without re-clamping.
1.Monolithic cast structure ensures rigidity/stability.
2.X/Z1 axes use oversized preloaded linear guides; Z2 employs hardened rails for sub-spindle precision.
3.High-speed electric main/sub spindles.
4.Dual-spindle concentricity <0.01mm.
5.8-station turret completes both ends in single clamping; Ideal for parts requiring shorter second-side machining.
