Pipe Threading Machine

Engineered for high-throughput production in demanding fabrication environments, the Pipe Threading Machine by National Cutting Tools is built for <p>The Pipe Threading Machine by National Cutting Tools is an industrial metalworking machine designed for cutting clean, leak-tight threads on mild steel, galvanized iron (GI), and seamless steel pipes. Manual pipe die stocks are slow and produce uneven tapers that leak under hydraulic pressure; this machine automates the threading process with an all-geared headstock, rigid pipe clamping, and a self-opening taper die head.</p>.

<p>Covering pipe sizes from 1/2" (15 mm NB) up to 2.1/2" (65 mm NB), the machine cuts standard BSPT and NPT tapered threads in a single fast pass. The built-in taper sine mechanism guides the chasers radially outward at exact 1:16 taper, producing standard-compliant pipe threads that seal tightly with standard fittings in plumbing, fire-fighting, and gas pipeline installations.</p>

<h3>Key Features</h3>

<ul>

<li><strong>Precision 1:16 Taper Mechanism:</strong> Automated sine bar guides cutters to form exact BSPT/NPT taper angles for guaranteed leak-tight joints.</li>

<li><strong>Multi-Speed Geared Headstock:</strong> Hardened gears provide 30, 60, and 90 RPM ranges to match pipe diameter and wall thickness.</li>

<li><strong>Self-Centering Pipe Vise:</strong> Dual-screw mechanical vise with hardened serrated jaws prevents pipe rotation under heavy threading torque.</li>

<li><strong>Self-Opening Die Head:</strong> Cutters retract radially outward the moment thread length is achieved, preventing thread scuffing.</li>

<li><strong>Rigid Cast Bed:</strong> Heavy graded cast iron base absorbs motor vibration and maintains alignment over years of workshop duty.</li>

<li><strong>High-Flow Cutting Fluid System:</strong> Motorized pump delivers continuous oil flow to flush chips and cool chasers for long cutting life.</li>
