The VL-300 to VL-600C/CM range from HONOR SEIKI represents their top-tier collection of Large Vertical Lathes, engineered to process the most massive and challenging workpieces in industries like wind power and heavy machinery manufacturing. With impressive capacities that include a maximum turning diameter reaching up to 7,000 mm (275.5 inches) and a maximum workpiece weight of 100,000 kgs, these machines are built for exceptional scale.

The structural integrity is ensured by a wide span column design and robust box way construction, which together provide the exceptional rigidity needed for turning huge-sized workpieces and hardened material. A key feature is the HONOR-patented Solid Lock tool clamping mechanism, which enhances tool stability during heavy cuts.

The series is split into two primary types: the standard C models, which focus purely on turning (up to 16 tool positions), and the high-performance CM models, which add multi-tasking capability. The CM models are equipped with live spindle speed (up to 2,250 rpm) and larger tool magazines (up to 24 positions), allowing for complex milling and drilling operations to be performed in the same setup. An optional dual spindle model is available across the range to highly improve the machining efficiency by allowing simultaneous or sequential operations, minimizing cycle times for large-scale production. Standard accessories include a complete splash guard, hydraulic power unit, and a chip conveyor, with optional features like a hydraulic chuck and a high-pressure coolant system available to tailor the machine to specific turnkey project requirements.
