CDS6266B / CDS6266C Large-Bore Gap-bed Horizontal Lathe is a conventional horizontal lathe designed for medium and large workpieces requiring greater turning clearance. The gap-bed structure provides additional space near the spindle, while the B and C versions offer 82 mm and 105 mm spindle bore options. It supports external and internal cylindrical turning, face turning, threading, drilling and boring. The machine is suitable for general machining in automotive, mold, communications, medical equipment and instrumentation industries.

CDS6266B / CDS6266C Large-Bore Gap-bed Horizontal Lathe is widely used for:

· Machining shafts, sleeves, discs, and flange parts
· Thread processing for metric, inch, module, and DP thread requirements
· Manufacturing and repair of automotive and mechanical components
· Mold maintenance and custom metal part processing
· General engineering workshops and industrial production

Large gap-bed turning capacity
The CDS6266B / CDS6266C Large-Bore Gap-bed Horizontal Lathe provides a 660 mm swing over bed, 440 mm swing over cross slide and 870 mm swing in gap. The gap length from the spindle nose is 280 mm.

Large spindle bore options
The B version has an 82 mm spindle bore, while the C version provides a 105 mm spindle bore for different workpiece requirements.

Rigid machine structure
The main machine structure uses resin-sand high-phosphorus castings. Finite element analysis and structural optimization help provide stable support during cutting.

Hardened and precision-ground guideways
The bed guideways are high-frequency hardened and precision ground, with a stated hardness of G50 to support wear resistance and long-term accuracy retention.

Precision gear transmission
Headstock gears are high-frequency hardened and precision ground, with a stated gear accuracy of Grade 6 to 7.

Machining quality
According to the supplied specifications, dimensional accuracy can reach IT7 and surface roughness can reach Ra 1.6 under suitable machining conditions.
