Large CNC Lathe
Large CNC Lathes: Heavy-Duty Metal Turning Solutions for Global Industry
Engineered for power, precision, and heavy workload capacity, Anyang Machine Tool provides heavy-duty CNC lathes built to handle demanding industrial turning operations worldwide. Designed to process oversized, high-tonnage workpieces with sub-millimeter precision, our heavy lathe machinery powers critical manufacturing sectors across global markets.
Heavy-Duty Turning Built for Scale
Large CNC lathes are high-rigidity horizontal and vertical turning centers optimized for machining heavy metal components with large diameters and long lengths. Driven by high-torque spindle motors, massive single-piece bed castings, and advanced numerical control systems, these machines execute heavy roughing, precision threading, boring, and complex profiling on hardened alloys without sacrificing machining stability.

Engineered for Extreme Turning Performance
Rigid One-Piece Cast Iron Bed
Resin sand casting aged naturally to eliminate internal stress and prevent structural deflection under heavy cutting loads.
Exceptional Load-Bearing Tailstock
Programmable hydraulic or motorized tailstocks safely support massive forged shafts during high-speed rotation.
Sub-Micron Machining Precision
Premium ball screws and optical linear scales maintain strict tolerances over long travel lengths.
Thermal Stability Design
Isolated headstocks and active cooling channels prevent heat distortion during multi-hour continuous cutting.
Heavy Cast Machine Base: High-density Meehanite iron construction provides the mass necessary to absorb heavy cutting vibrations.
High-Torque Headstock: Heavy gearboxes powered by digital AC servo drives deliver low-RPM, high-torque output for deep metal removal.
Precision Spindle Assemblies: Fitted with high-precision angular contact bearings, ensuring true radial runout stability under heavy loads.
Automated Tool Turrets: Heavy 8 or 12-station hydraulic turrets fit large-shank tooling for fast, rigid tool indexing.
Hardened Precision Guideways: Wide, induction-hardened ways coated with Turcite-B friction material eliminate stick-slip motion.
Machining Capabilities
Heavy Roughing
Removes large volumes of tough forged steel and alloy stock quickly.
Deep Hole Boring
Executes long-reach internal diameter turning and boring with high concentricity.
API Thread Cutting
Produces straight, tapered, and oilfield pipe threads with high accuracy.
Complex Contour Profiling
Generates complex tapers, radii, and multi-axis curves directly through CNC commands.
Oil & Gas Equipment: Turns drill collars, thick-walled casing pipes, valve bodies, and downhole tool bodies.
Maritime & Shipbuilding: Machines long propeller shafts, rudder stocks, and large marine engine components.
Mining & Heavy Equipment: Processes excavator pins, crusher shafts, and large transmission gear blanks.
Power Generation: Handles steam turbine rotors, generator shafts, and heavy flange rings efficiently.
Aerospace & Defense: Shapes large structural forgings, turbine disks, and rocket housing components.
Tailored Customization Options
Extended Bed Lengths
Modular frame extensions custom-built to support ultra-long shaft requirements.
01
Live Tooling & C-Axis
Enables milling, cross-drilling, and keyway cutting in a single setup to eliminate extra machine transfers.
02
Dual Turret Configuration
Upper and lower turrets operate simultaneously to double machining efficiency on symmetrical workpieces.
03
Automated Chip Conveyors
Custom chip management systems designed to clear continuous heavy metallic shavings automatically.
04
CNC Control System Configuration
Our large turning machinery comes integrated with industrial control systems including FANUC, Siemens, and Fagor. Standard configurations feature conversational multi-axis programming interfaces, automatic thermal expansion compensation, real-time tool load monitoring, and ergonomic manual pulse generators (MPG) for setup safety on large workpieces.
In-House Manufacturing & Quality Control
Every large CNC lathe is built inside our standardized manufacturing facilities under strict ISO9001 quality management protocols. Critical structural castings are precision-ground on heavy German guideway grinders. Prior to dispatch, each machine undergoes laser interferometer calibration, dynamic spindle balancing, and a continuous 24-hour dry-run testing cycle to ensure full CE compliance and stable operational performance.
