Heavy Industrial SPM
Model: NCT-SPM-44
Comprehensive Machine Overview
Designed to maintain strict dimensional tolerances under continuous multi-shift production, the Bed Type Bolt Cum Pipe Threading Machine provides <p>The Bed Type Bolt Cum Pipe Threading Machine is engineered with an extended, heavy-duty lathe-style bed to provide rigid carriage support and superior stability when threading long structural bolts, tie rods, and pipes. Standard compact threading machines can suffer carriage deflection when supporting long overhanging workpieces; our bed-type design distributes carriage load across wide, hand-scraped prismatic guideways to maintain sub-millimeter axial alignment throughout the cut.</p>.
<p>Featuring a heavy-duty all-geared headstock and dual-purpose tooling, the machine threads solid steel bolts up to M65 / 2.1/2" diameter as well as nominal bore pipes from 1/2" to 2.1/2". The extended bed accommodates long lead-screw travel and optional traveling steady rests, ensuring pitch linearity and uniform thread profile from end to end on heavy-duty construction fasteners.</p>
<h3>Key Features</h3>
<ul>
<li><strong>Extended Lathe-Type Cast Bed:</strong> High-tensile close-grained cast iron bed provides exceptional rigidity and absorbs heavy cutting harmonics.</li>
<li><strong>Wide Hand-Scraped Guideways:</strong> Flat and prismatic ways maintain carriage squareness and eliminate tool deflection under heavy radial cutting forces.</li>
<li><strong>Dual Capability Vise Assembly:</strong> Universal clamping vise holds both solid hexagonal/round bars and hollow steel tubes securely on center.</li>
<li><strong>All-Geared Headstock with Splash Oiling:</strong> Hardened alloy gears deliver multi-speed torque (30, 60, 90 RPM) for diverse material diameters.</li>
<li><strong>Self-Opening Tangential Die Head:</strong> Instantaneous radial release at preset length stops prevents thread scuffing on carriage retract.</li>
<li><strong>Lead Screw & Manual Rack Dual Feed:</strong> Lead screw ensures exact pitch on high-tensile solid bolts; rack feed speeds up pipe threading cycles.</li>
</ul>
<h3>Applications</h3>
<ul>
<li>Heavy foundation bolt, anchor bolt, and stud threading for industrial plants</li>
<li>Long pipe end threading for plumbing, fire-fighting, and gas distribution</li>
<li>Structural tie rod and sag rod threading for steel building contractors</li>
<li>Job-shop and machine-shop multi-purpose threading operations</li>
</ul>
<p>Manufactured and assembled at National Cutting Tools in Focal Point, Ludhiana. Calibrated with master thread gauges and test-cut on customer material samples before dispatch across India and overseas.</p>

Bed Type Bolt Cum Pipe Threading Machine Works QA & Export Packaging Protocol
✓ Continuous Stud & Pipe Threading Accuracy Protocol
- • Continuous Thread Pitch Lead Accuracy: Thread lead screw accuracy verified over 1000 mm bar lengths to eliminate pitch cumulative error on long threaded rods.
- • Automatic Die Head Trip Synchronization: Carriage length stop and automatic chaser opening mechanism calibrated within 0.5 mm for repeatable thread length.
- • Dual Speed Headstock Load Test: Spindle rotation tested across bolt threading speeds and slower pipe threading gear reductions under full cutting load.
- • Thread Sample Dispatch Sign-Off: Sample threaded pipe and solid stud specimens measured and recorded in pre-dispatch inspection certificate.
Precision Threading Machine Transit Protection
- • Die & Lead Screw Wax Coating: Chasers, thread rolls, vice jaws, and lead screws coated with heavy-viscosity protective rust-preventive petroleum wax.
- • Carriage Mechanical Locks: Workpiece carriage and rack gear secured to prevent movement and shock during sea transit.
- • Cabinet Desiccant Packs: Hermetically sealed silica gel canisters placed inside control enclosures to prevent condensation.
- • ISPM-15 Heat-Treated Crating: Heavy wooden box packaging compliant with international maritime phytosanitary export standards.
