The CK5120 vertical lathe is a heavy-duty machining solution tailored for large workpieces, featuring a 2000mm maximum turning diameter of the vertical tool rest and 1800mm workbench diameter. It can handle workpieces up to 1250mm in height and 8T in weight, making it ideal for precision processing of heavy rotating parts such as large flanges, bearing housings, and wind turbine components.
Powered by a 30kW high-performance main motor and 2.2kW lifting motor, the CK5120 delivers robust and stable power output. Its table speed adjusts flexibly between 6-100r/min, paired with a 0.1-2000mm/min tool rest feed range and 2000mm/min tool holder fast moving speed, adapting to diverse cutting requirements for materials like carbon steel, stainless steel, and cast iron.
The CK5120 boasts practical and safe configurations: it adopts a 30×40mm cutterbar compatible with various heavy-duty cutting tools, while the 30° limit of the vertical tool holder wrench angle ensures operator safety during operation. The vertical tool rest offers 1100mm horizontal travel and 750mm vertical travel, covering multi-directional cutting needs for complex large workpieces.
With a machine weight of 16T, the CK5120 features exceptional structural rigidity, which effectively suppresses machining vibration and maintains high processing precision even under full-load (8T workpiece weight) operations. This stability makes it a reliable choice for heavy-duty machining in industries such as construction machinery, power equipment, and shipbuilding.
Combining large-load capacity and efficient machining, the CK5120 vertical lathe stands out with its 8T maximum workpiece weight—higher than smaller models—paired with a 1250mm wide workbench for stable workpiece support. The wide range of table speed and feed rate, plus the tool holder's fast movement, significantly reduces auxiliary time and improves overall production efficiency for large-part manufacturing.
