Heavy Industrial SPM
Model: NCT-SPM-81
Comprehensive Machine Overview
Built on a heavy structural frame to eliminate vibration harmonics and maintain precision, the Two Roll Hydraulic Thread Rolling Machine manufactured by National Cutting Tools delivers <p>The Two Roll Hydraulic Thread Rolling Machine by National Cutting Tools is a heavy-duty cold metal-forming machine tool engineered for rolling precision threads, knurls, and worms on solid steel bars, studs, and scaffolding jack screws. Unlike cutting methods that produce swarf and sever grain lines, thread rolling cold-forges the metal into the die profile, increasing thread tensile strength by up to 20–30% and producing mirror-smooth, work-hardened thread surfaces.</p>.
<p>Featuring two precision-ground alloy tool steel circular dies mounted on heavy forged spindles, the machine operates through a high-pressure hydraulic power pack that forces the movable roll head against the workpiece on the stationary roll head. The machine supports both in-feed (plunge) rolling for short bolts and continuous through-feed rolling for long threaded bars and jack screws at output speeds up to 1.5 to 3.0 meters per minute.</p>
<h3>Key Features</h3>
<ul>
<li><strong>In-Feed & Through-Feed Rolling Modes:</strong> In-feed handles headed bolts and studs; through-feed enables continuous rolling of long rods.</li>
<li><strong>Heavy Hydraulic Squeeze Tonnage (15–35 Tons):</strong> Infinitely adjustable rolling force handles high-tensile carbon and alloy steels without motor strain.</li>
<li><strong>Precision Ground Roll Spindles:</strong> Forged Ni-Cr alloy spindles mounted in heavy spherical roller bearings resist massive radial separating forces.</li>
<li><strong>Micro-Adjustable Center Distance & Angle:</strong> Allows fine tilt calibration of rolls for through-feed helix pitch matching.</li>
<li><strong>Zero Material Waste & Superior Strength:</strong> Cold-forming generates zero chips and increases thread fatigue strength by preserving grain continuity.</li>
<li><strong>PLC / Relay Automatic Cycle Control:</strong> Features automated cycle timer, rapid approach, dwell time, and pressure relief settings.</li>
</ul>
<h3>Applications</h3>
<ul>
<li>Cold rolling scaffolding base jack and U-head screw threads (Tr36, Tr38, Tr48)</li>
<li>High-output foundation bolt, tie rod, and anchor stud thread rolling</li>
<li>Automotive fastener, wheel stud, and steering rack worm rolling</li>
<li>Knurling, serrating, and spline rolling on transmission shafts</li>
</ul>
<p>Manufactured and assembled at National Cutting Tools in Ludhiana, Punjab. Calibrated with master thread gauges and test-rolled on buyer steel bar stock before factory dispatch.</p>
High-Yield Production Capabilities & Advantages
High-Strength Cold Grain Forming
Rolling compresses the steel grain structure rather than cutting it, increasing surface hardness by 15–20% and preventing stripping.
15T to 60T Hydraulic Force
High-pressure hydraulic slide cylinders provide rigid penetration power for high-tensile carbon and alloy steels (Grade 8.8, 10.9).
Through-Feed & In-Feed Capability
Handles long scaffolding tie-rods and coil rods up to 6 meters via continuous through-feed, or short bolts via precision in-feed.
Hardened D2/Cr12MoV Rolling Dies
Precision CNC ground alloy dies deliver Class 6g and 2A/2B thread pitch accuracy over millions of production cycles.
Continuous Industrial Duty
Heavy gear reduction box and high-capacity hydraulic oil heat exchanger ensure 24/7 continuous operation without thermal breakdown.

Two Roll Hydraulic Thread Rolling Machine Works QA & Export Packaging Protocol
✓ Thread Geometry & Pitch Gauge Verification Protocol
- • Thread Pitch & Gauge Inspection: Sample threads cut or rolled on bar/pipe stock verified with calibrated Go / No-Go thread ring and plug gauges (IS 554 / ISO 7 / IS 16172).
- • Chaser / Roll Die Parallelism: Die head trip mechanism and roll die spacing aligned within 0.02 mm under full cutting and forming torque.
- • All-Geared Headstock Burn-In: 48-hour continuous trial of all spindle speeds and coolant circulation under loaded cutting conditions to ensure thermal stability.
- • Thread Sample Sign-Off: Physical threaded test samples preserved and HD video of threading cycle sent for buyer approval before packing.
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.
