CW6163B Heavy Duty Horizontal Conventional Lathe

The Skymach CW6163B Heavy Duty Horizontal Conventional Lathe is universal metal machining equipment engineered for demanding industrial metal turning, cylindrical roughing, external and internal tapering, thread chasing, and oil-groove machining. Built on a continuous 550 mm wide solid straight bed with 630 mm swing over bed and 350 mm swing over carriage, the CW6163B delivers massive dynamic rigidity capable of supporting up to 3 tons (3000 kg) between centers.

Equipped with a 11 kW high-torque spindle motor, an 18-step geared transmission (7.5 - 1000 rpm), and an A2-11 spindle nose with large Metric Φ104 mm / Φ120 mm through-bore, the CW6163B is ideal for processing cast iron, alloy steel, forgings, non-ferrous metals, and heavy tubular stock. A comprehensive quick-change feed gearbox accommodates 50 metric, 26 inch, 53 module, and 24 DP pitch threads, while an independent 1.1 kW rapid motorized traverse mechanism accelerates longitudinal and cross-slide positioning to maximize productivity in production machine shops and heavy maintenance facilities.

Sea-Freight Security

Export Packaging & Container Loading Standards

Heavy-duty CNC machinery requires uncompromising protection during ocean transit. Every Skymach machine undergoes strict multi-stage sea-worthy packaging meeting international ISPM-15 standards.

Step 01

Anti-Rust Oil & Vacuum Moisture-Proof Wrap

All precision ground surfaces and guideways are coated with heavy anti-rust oil, sealed in thick vacuum foil, and packed with industrial desiccants.

Step 02

ISPM-15 Fumigation-Free Solid Wooden Crate

Heavy steel or reinforced timber pallet base with solid plywood casing, fully compliant with international quarantine and customs clearance rules.

Step 03

In-Container Steel Wire Tension Lashing

Dual diagonal high-tensile steel wire turnbuckles and heavy triangular floor chocks secure the machine firmly against rough sea turbulence.

Step 04

Safe Crane Hoisting & 40HQ Container Loading

Professional heavy-duty forklift and crane operators ensure smooth, shock-free positioning into standard 20GP or 40HQ ocean shipping containers.
