CDS6250B / CDS6250C Gap‑bed Heavy‑Duty Horizontal Lathe-Qi Fa (Jiangsu) Machinery Co., Ltd.

CDS6250B / CDS6250C Gap-bed Heavy-Duty Horizontal Lathe is a conventional horizontal lathe designed for general turning of medium and large workpieces. Its gap-bed structure provides additional clearance for workpieces with larger diameters near the spindle area. The machine supports external and internal cylindrical turning, face turning, threading, drilling and boring. B and C versions offer 82 mm and 105 mm spindle bore options for different machining requirements.

CDS6250B / CDS6250C Gap-bed Heavy-Duty Horizontal Lathe is widely used for:

· Thread cutting for metric, inch, module, and DP threads
· Turning and boring of automotive and machinery components
· Mold repair and custom metal part production
· Maintenance workshops, vocational training, and general engineering

Gap-bed turning capacity
The CDS6250B / CDS6250C Gap-bed Heavy-Duty Horizontal Lathe provides a 500 mm swing over bed, 290 mm swing over cross slide and 760 mm swing in gap, with a 280 mm gap length from the spindle nose.

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

Rigid machine structure
Resin-sand high-phosphorus castings are used for the main machine structure. Finite element analysis and structural optimization support stable cutting performance.

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 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
Based on the supplied specifications, dimensional accuracy can reach IT7 and surface roughness can reach Ra 1.6 under suitable machining conditions.
