GD-4640Y Small-Sized Turn-Mill Compound Machining Center

01.

Performance: This CNC turn mill has an integrated bed design with smooth chip removal, and a single-piece inner protection structure is durable. The spindle adopts internal motor transmission (electric spindle) with a maximum speed of 4000rpm. Double feedback induction indexing paired with hydraulic locking ensures precise positioning. The servo tailstock adopts linear guides with high precision and adjustable torque. A BMT40 servo power turret (15 stations) has a Y-axis stroke of 80mm (40mm up and down), supporting turning, milling, and drilling compound processing. This CNC turn mill is compact and efficient.

Adaptability and Process Expandability

Focusing on turn-mill compound processing of small-sized disc, sleeve, and shaft parts, this CNC turn mill is compatible with various materials. It has a maximum processing diameter of Φ320mm, a processing length of 300mm, and a spindle through hole of Φ56mm. It completes multiple processes with one clamping, adapting to batch production of small complex precision parts, with convenient operation and fast tool change.

Qualification Certification

Certified with ISO9001 quality management system, the small-sized turn-mill compound processing precision and equipment reliability of this CNC turn mill have passed international standard verification.

Summary

With compact structure and compound functions as the core, focusing on integrated processing of small complex parts, it is a cost-effective choice for small and medium-batch precision manufacturing.
