Q: How do I choose between the ∅65 mm and ∅82 mm spindle through-hole configurations for the CK6140 small CNC lathe?

A: Your choice should be determined by your primary raw material supply form:

• Choose the 65 mm Spindle (A2-6 / 200 mm Chuck): If your workflow revolves around secondary turning of pre-cut slugs, blanks, or small bar stock under 50 mm. This setup maximizes high-speed velocity up to 2,000 RPM.
• Choose the 82 mm Spindle (A2-8 / 250mm Chuck): If you run continuous automated bar-feeding operations for larger stock. This larger specification provides an 80 mm bar passage diameter and supports up to an 80 mm internal diameter hydraulic drawbar cylinder upgrade, allowing large-diameter raw bar stock to pass completely through the headstock.

Q: Under what production scenarios should I upgrade from the standard 4-station tool post to a 6/8-station turret and a hydraulic tailstock?

A: The standard 4-station electric tool post is ideal for low-complexity parts requiring only basic facing, roughing, finishing, and threading tools. However, if your component mix involves complex internal boring, groove-cutting, and multi-pitch threading on a single part, upgrading to a 6- or 8-station turret prevents tool-count bottlenecks. For shops looking to minimize cycle times, pairing this turret with an optional hydraulic chuck and hydraulic tailstock allows you to control the entire workholding sequence via CNC system M-codes, transitioning the machine into a semi-automated cell.

Q: Why is the compact CK6140 ideal for small toolroom shops with limited floor space?

A: Small toolrooms and job shops often face a classic dilemma: standard industrial lathes take up too much floor space, while compact "benchtop" or garage-level lathes lack the mechanical rigidity to handle tough steels or deliver professional finish tolerances. The CK6140 delivers heavy-duty industrial rigidity within a space-saving footprint, bridging the gap between bulky production machines and underpowered benchtop lathes. Spanning just 2,200 mm in length, it easily fits into tight workshop layouts while maintaining uncompromised cutting capabilities. It packs the exact precision, torque, and component lifespan of a large-scale factory lathe into a compact, space-saving frame—allowing small shops to machine tough materials to tight tolerances efficiently.
