The CW6163B Large-Bore Conventional Lathe is built for precise turning of heavy-duty, long shaft, and large-diameter rotary components. Designed with a 630 mm swing over bed, a 100 mm through-spindle bore, and a 550 mm extra-wide bed structure, this model delivers maximum stability during heavy metal removal. It handles workpiece lengths ranging from 750 mm up to 10,000 mm, making it an essential workhorse for heavy machinery manufacturing, oilfield pipe processing, power generation, and general mechanical repair shops.

Key Features of CW6163B Large-Bore Conventional Lathe
High-Rigidity HT300 Cast Bed: Cast from high-grade HT300 iron with an internal double-ribbed box structure, effectively absorbing cutting vibrations during high-torque turning.
100 mm Clear Spindle Bore: Supports direct through-spindle feeding for long shafts, drill pipes, and tubing, eliminating unnecessary external preparation steps.
Induction-Hardened Guideways: Bedways are precision-ground and high-frequency induction hardened (HRC52+) to ensure long-term mechanical accuracy under heavy loads.
TSF Wear-Resistant Lining: Carriage guideways feature bonded TSF soft-band PTFE plates, offering low friction coefficient and preventing stick-slip during slow-speed precision feed.
Universal Thread Cutting: Integrated feed gearbox handles metric, inch, module, and diametral pitch threads directly without manually changing change-gears.
Machining Precision & Structural Stability
Engineered for strict industrial tolerances, the lathe features a hardened C11 spindle nose supported by high-precision heavy-duty roller bearings. This setup guarantees rotational accuracy even during aggressive roughing operations.
The extra-wide 550 mm bed rail spreads cutting loads across a broader foundation, reducing deflection when turning long shafts or heavy off-center castings.
Tailstock & Taper Turning Performance
The heavy-duty tailstock features a 100 mm diameter quill with 250 mm travel and a Morse No. 5 taper, providing rigid support for long workpieces.
The top compound slide operates independently for turning short steep tapers, while combining top-slide angle settings with longitudinal feed controls allows accurate machining of extended external and internal taper surfaces.
Typical Applications
Energy & Oilfield Tools: Turning drill pipes, casing tubes, API threaded couplings, and flange connections.
Heavy Transportation: Machining long drive shafts, hydraulic cylinders, axles, and large railway components.
Industrial Maintenance: Refurbishing worn shafts, cutting custom lead screws, and internal/external cylinder re-boring.
Standard Configuration & Custom Options
Standard Equipment
325 mm Three-Jaw Manual Chuck: Precision-balanced chuck mounted to C11 spindle nose for reliable concentric clamping.
Support Rests: Includes one steady rest and one follow rest for bed lengths of 2 meters and above to prevent long-shaft deflection.
Coolant System & Chip Tray: High-flow coolant pump with full-length chip collector tray for continuous heavy cutting operations.
Lighting & Foundation Hardware: Bright LED worklamp for clear zone illumination and heavy-duty anchor bolts for foundational grounding.
Customization Options
Workholding Upgrades: Independent 4-jaw chucks, specialized faceplates, or enlarged diameter three-jaw chucks.
Heavy-Duty Rest Systems: Oversized roller-type steady rests engineered specifically for large-diameter shafts or heavy forgings.
Precision Accessories: Multi-axis Digital Readout (DRO) systems for faster positioning and rear tool posts for secondary operations.
Split-Bed Construction: Modular split-bed design required for long-bed models exceeding 6 meters to simplify transport and setup.
