Friction Screw Press

Built on a heavy structural frame to eliminate vibration harmonics and maintain precision, the Friction Screw Press manufactured by National Cutting Tools delivers <p>The Friction Screw Press by National Cutting Tools is a heavy-duty forging and coining machine tool engineered for hot forging, warm pressing, and cold coining of steel components. In scaffolding component manufacturing, forged fittings such as drop-forged swivel couplers, double couplers, and Cuplock ledger blades require immense impact energy combined with high dead-weight pressing force to fill complex die impressions without forging cracks or incomplete fill.</p>.

<p>Constructed with a heavy cast steel frame and high-tensile tie rods, the machine features a large-diameter forged alloy screw with multi-start threads, a heavy friction flywheel, and dual motorized friction driving discs. When the operating lever is engaged, the friction discs accelerate the flywheel and screw downward, delivering massive kinetic energy at bottom dead center to forge tough alloy steel billets into net-shape components.</p>

<h3>Key Features</h3>

<ul>

<li><strong>Massive Forged Alloy Steel Screw:</strong> Heat-treated alloy steel screw with precision-machined Acme threads absorbs heavy forging shock without fatigue.</li>

<li><strong>Heavy Friction Flywheel & Driving Discs:</strong> Dynamically balanced flywheel coated with high-friction linings provides efficient power transfer from dual drive discs.</li>

<li><strong>High Energy Impact at Stroke End:</strong> Delivers sharp impact energy followed by continuous screw squeeze, ideal for forging complex die cavities.</li>

<li><strong>Rigid Cast Steel Frame with Pre-Stressed Tie Rods:</strong> Resists severe forging shock waves, maintaining die alignment over decades of forge shop service.</li>

<li><strong>Automatic Bottom Ejector Mechanism:</strong> Mechanical or pneumatic knock-out pin ejects hot forgings instantly from the bottom die to speed cycle turnaround.</li>

<li><strong>Adjustable Blow Energy Control:</strong> Regulates flywheel stroke and speed to match small forging blanks or heavy multi-cavity coupler dies.</li>

</ul>

<h3>Applications</h3>

<ul>

<li>Hot forging scaffolding drop-forged couplers (swivel, fixed, sleeve couplers)</li>

<li>Forging Cuplock ledger blades and Ringlock cast/forged wedge heads</li>

<li>Hand tool manufacturing: spanners, pliers, hammer heads, and chisels</li>

<li>Automotive steering knuckles, connecting rods, and flange forgings</li>

</ul>

<p>Manufactured and tested at the National Cutting Tools plant in Ludhiana, Punjab. Every screw press undergoes dynamic forging proof tests on steel billets before release for dispatch.</p>
