Product Description

CK680 CNC Lathe | High-Torque, Heavy-Duty Precision Machine

Intelligent Structure, Built to Perform

The CK680 CNC Lathe is designed with a fully integrated cast iron bed and base, offering rock-solid rigidity and stability. With a clean, ergonomic layout that prioritizes cooling, protection, and cable management, every detail speaks to quality craftsmanship and user-friendly operation.

Powerful Spindle System

Featuring a high-rigidity spindle supported by double-row cylindrical roller bearings, the CK680 handles both radial and axial loads like a pro. Its Φ86mm large through-hole and A2-8 spindle nose allow broad tooling compatibility. Optional C-axis upgrade and braking system turn this lathe into a turning-milling powerhouse.

Precision Engineering at Its Core

The X-axis runs on a rectangular guideway with a 300×800mm cross slide and 5×14mm T-slots, while the Z-axis adopts a 520mm wide double-inclined bed with a center-mounted ballscrew. These features give the CK680 superior precision, stability, and expandability-perfect for adding milling, drilling, or grinding heads.

Ultimate Machining Flexibility

This machine offers incredible versatility: support for gang tool posts, power turrets, U-drill holders with through-coolant, and even hybrid setups. Spindle speeds reach up to 1650rpm, with a swing over bed of Φ780mm and X-axis travel of 520mm-ready for heavy-duty work and complex part geometries.

Smarter Control, Longer Life

Equipped with a trusted CNC control system and high-end drive units, the CK680 ensures smooth, responsive operation. European-brand electrical components, precision assembly, and laser calibration guarantee long-lasting accuracy. Plastic-coated sliding surfaces reduce wear and improve positioning, giving this lathe serious longevity.
