Shenyang CW6280B Used Lathe

The Shenyang CW6280B is a heavy-duty horizontal lathe renowned for its robust construction and versatility in machining large workpieces. When evaluating a used CW6280B, the “C parameters” (core technical specifications) offer distinct advantages that make it a reliable choice for industries requiring precision and durability. Below is a breakdown of these advantages based on verified technical data:

Heavy-Duty Spindle System

Spindle Bore:

The lathe features a 105 mm or 130 mm spindle bore (depending on the model), allowing through-hole machining of large-diameter bars or pipes. The D1-11 spindle nose ensures secure clamping of heavy-duty chucks and fixtures.
Spindle Speed Range:

With 18 selectable speeds ranging from 7.5–1,000 RPM (manual models) or 10–800 RPM (hydraulic variants), the CW6280B balances high torque for rough cutting and fine control for precision finishing. This flexibility is essential for machining materials with varying hardness, from aluminum to hardened steel.
Heavy Machinery Repair: Refurbishing large shafts, gears, and engine components.
Oil and Gas: Machining drill collars, valves, and pipelines.
Power Generation: Manufacturing turbine parts and generator shafts.
Construction: Cutting and threading structural steel elements.
