SHANDONG SANZHENG CW6280B/5000 MANUAL LATHE

Technical Description

The SHANDONG SANZHENG CW6280B/5000 is a heavy-duty conventional horizontal lathe designed for large-diameter turning operations and precision metal machining. This machine features an 800mm (31.5-inch) maximum swing diameter over the bed, enabling the processing of substantial workpieces up to 5000mm (196.9 inches) in length between centers. The lathe accommodates a maximum workpiece load capacity of 2.5 tons with a guide rail width of 600mm, providing excellent stability and rigidity during operation. Equipped with an 11kW (14.8 HP) spindle motor delivering speeds ranging from 6 to 800 RPM across 18 stepped speeds, this machine enables versatile cutting applications including turning, threading, boring, and groove broaching. The spindle bore diameter of approximately 105mm (4.1 inches) with a D11 nose configuration accommodates various tool holders and workholding devices. Feed capabilities include 64 longitudinal feed steps ranging from 0.05 to 24.3mm per revolution, with a corresponding cross-feed ratio of 1:2 and rapid traverse speed of 4000mm per minute. The carriage features maximum cross-slide travel of 480-540mm and upper slide travel of 200mm for precise tool positioning. Threading versatility includes metric (1-240mm modules), inch (14-1 TPI), and Diametric Pitch (DP) threads. The tailstock incorporates 250mm quill travel with MT5/MT6 taper accommodation for additional tooling options. This robust machine is constructed with composite bed architecture featuring double finning plates for enhanced integral rigidity and structural stability during heavy-duty machining operations.
