| 1 | Heavy-Duty Single-Column VTL | Steel, energy, mining and large-component manufacturers | 1,600–3,150 mm | 1,200–2,000 mm | 1,250–2,500 mm | 2–250 rpm | 55–110 kW | ±0.02–0.05 mm | High rigidity, strong low-speed torque, large work envelope and excellent chip evacuation | Large footprint, higher installation cost and longer setup time |
| 2 | Double-Column CNC VTL | Aerospace, power-generation and large-diameter machining operations | 2,500–8,000 mm | 1,600–4,000 mm | 2,000–6,300 mm | 0.5–100 rpm | 90–250 kW | ±0.03–0.08 mm | Supports very large workpieces, stable cross-rail design and multiple rams or tool posts | Highest capital cost and demanding foundation requirements |
| 3 | Medium-Duty Slant-Bed VTL | General engineering, automotive components and job shops | 800–1,600 mm | 700–1,200 mm | 630–1,250 mm | 5–1,200 rpm | 22–55 kW | ±0.01–0.03 mm | Good chip flow, compact layout, accessible workholding and balanced production capability | Less suitable for extremely heavy interrupted cuts |
| 4 | Compact High-Speed VTL | Automotive, bearing, hydraulic and high-volume component producers | 500–1,000 mm | 500–800 mm | 400–800 mm | 50–2,500 rpm | 15–37 kW | ±0.008–0.02 mm | Short cycle times, automatic loading compatibility and efficient use of factory space | Limited workpiece diameter and lower heavy-cutting capacity |
| 5 | Live-Tooling VTL with C-Axis | Multi-operation machining and manufacturers seeking fewer setups | 600–1,500 mm | 600–1,200 mm | 500–1,250 mm | 5–1,000 rpm | 22–45 kW | ±0.01–0.03 mm | Turning, milling, drilling and tapping in one setup; reduces handling and alignment errors | Higher programming complexity and increased maintenance requirements |
| 6 | Two-Ram Production VTL | High-throughput manufacturers requiring simultaneous operations | 1,000–2,500 mm | 800–1,800 mm | 800–2,000 mm | 3–400 rpm | 45–90 kW | ±0.02–0.05 mm | Parallel cutting, reduced cycle time and flexible roughing-finishing combinations | More expensive tooling, controls and operator training |
| 7 | Entry-Level CNC VTL | Small workshops, maintenance departments and developing markets | 500–1,000 mm | 500–800 mm | 400–800 mm | 10–800 rpm | 11–30 kW | ±0.02–0.05 mm | Lower purchase cost, simpler operation, modest utility demand and easier installation | Fewer automation options and lower productivity for complex or large parts |
