YJ-CK250ST Dual-spindle Dual-Turret CNC Machine for Large-size Shaft Parts

Dual-Chuck spindlestock, Stable Quality & Versatility: Adopting a symmetrical clamping structure with dual chucks on the spindlestock, replacing traditional one-way asymmetric clamping, it effectively suppresses cutting vibration, ensuring part surface quality, dimensional, and positional accuracy. A relief groove between the chucks adapts to shaft parts with special middle structures, greatly enhancing machining versatility.

Extendable Dual-Way Spindle, Flexible & Cost-Saving: Equipped with an extendable dual-way spindle, consisting of a sleeve assembly, detachable extension sleeves at both ends, and embedded collets. The control structure of the sleeve assembly drives one side of the extension sleeve to move axially, realizing precise expansion and contraction of the collet. Clamping specifications can be adjusted by replacing only some parts, significantly reducing spindle replacement and maintenance costs, and expanding the adaptation range.

Intelligent Control System, Stable & Efficient: Integrating 1 set of shared spindlestock transmission control system and 2 sets of symmetrical turret operation systems, it uses PLC control to replace some relays, optimizes circuit design to improve stability, simplifies wiring, and lowers operation threshold. Equipped with roller linear guides and a 25×25 tool square, the spindle has a through hole of φ120-245mm, stepless speed change of 100-500rpm, and a 15KW/18.5KW high-power motor, adapting to large-size part processing.
