Sub‑spindle Jaws & Back Spindle Coolant Ejectors for Swiss CNC Lathe

Sub‑spindle jaws and back‑spindle ejectors are critical wearing parts for swiss‑type CNC lathe secondary‑operation. Reliable gripping and smooth workpiece ejection directly improve production efficiency and reduce scrap rate. cnclatheparts provides aftermarket sub‑spindle jaws and coolant ejectors compatible with most mainstream swiss lathe machine brands for global precision component workshops.

Main Sub‑spindle & Back‑spindle Components

• Opening‑closing sub‑spindle chuck jaws: Standard jaws for holding finished workpieces in second‑operation
• Hardened special‑profile jaws: Custom inner contour for irregular‑shape workpiece gripping
• Back‑spindle coolant ejector standard type: With internal cooling channel for workpiece pushing‑out and heat dissipation
• Extended‑nose ejector: For long‑size workpiece ejection requirements
• Brand‑specific replacement sets: Fit STAR, Citizen, Tsugami, Tornos sub‑spindle assembly
• Drawing‑custom sub‑spindle parts: Custom dimension, hardness and surface treatment according to specifications

Material & Technical Parameters

Sub‑spindle jaws and back‑spindle ejectors adopt forging, heat‑treatment hardening and multi‑step precision grinding process. Nitriding option greatly enhances surface wear resistance under frequent cyclic gripping and ejection. Coolant channel design of ejectors assists cutting‑heat removal during secondary‑operation turning, decreasing thermal deformation risk of small precision parts.

Common‑model sub‑spindle jaws and ejectors are stocked for quick bulk delivery, with favorable tiered factory price for stable factory partners. We support non‑standard custom based on customer drawings, sample verification before mass shipment is acceptable. Our technical team offers component‑selection consultation and full‑process after‑sales order tracking for overseas buyers of swiss‑lathe consumables.
