Key Technical Features
Vibration-Damping Structure:
Symmetrical heavy cast-iron column design absorbs cutting forces and maintains thermal stability during long machining cycles.
High-Torque Spindle System:
Multi-stage hydraulic speed changing or high-power AC spindle motors deliver continuous high torque at low RPMs for heavy roughing.

Versatile CNC Controllers:
Standardized with industry-leading CNC platforms including Fanuc, Siemens, or Mitsubishi.
Optimal Gravity Chip Flow:
Chips and coolant fall directly away from the cutting zone into the lower chip conveyor, extending tool insert life and preventing re-cutting of swarf.
Industries Application
Wind turbine hubs, bearing housings, pitch rings
Heavy valve bodies, flanges, pressure vessel components
Brake discs, flywheels, wheel hubs, differential cases
Gear blanks, slewing rings, large hydraulic cylinders
Machine Types
Single-Column Vertical CNC Lathe:
Compact footprint engineered for medium-to-large circular parts like brake discs, flywheels, and standard pipe flanges.
Double-Column Vertical CNC Lathe:
Crossbeam bridge structure delivering maximum structural rigidity for heavy power-generation equipment, large valve bodies, and large-diameter ring gears.
Heavy-Duty Vertical CNC Lathe:
Reinforced bed castings and high-torque geared spindles built for extreme chip-removal rates in tough alloy steel turning.
CNC Vertical Turning Center (VTC with Live Tooling):
Combines C-axis spindle positioning with live tooling to handle turning, milling, drilling, and tapping in a single setup.
Core Components
Machine Bed & Column:
Thermo-symmetrically designed Meehanite cast frame, stress-relieved via double annealing to guarantee permanent geometric stability.
Spindle Assembly:
Ultra-precision NN30 series double-row roller bearings paired with angular contact thrust bearings, providing high radial load capacity and running accuracy within 0.005 mm.
Turret & Tooling System:
High-rigidity hydraulic indexing turret with curvic coupling clamping for repeatable positional accuracy during heavy interrupted cuts.
Guideways & Ball Screws:
Induction-hardened and ground box guideways with Turcite-B anti-friction lining, driven by pre-loaded C3-class precision ball screws.

We adapt VTL configurations around specific buyer manufacturing workflows:
Dimensional Matching: Spindle travel, chuck size, table diameter, and column height customized to part geometry.
Process Optimization: Special tooling blocks, high-pressure coolant through tool (20 to 70 bar), and integrated tool setters.
Automation Upgrades: Automatic pallet changers, robotic arm loading/unloading interfaces, and post-process gaging systems.
