Hydraulic Thread Cutting Machine

The Hydraulic Thread Cutting Machine is a dedicated industrial system engineered by National Cutting Tools for <p>The Hydraulic Thread Cutting Machine is a heavy-duty production machine tool engineered for high-volume, precision external threading on metal pipes, bolts, and round solid bars. By substituting manual handwheel feed and mechanical vise levers with hydraulic clamping, saddle travel, and automated die-head opening, the machine delivers repeatable thread depths and clean flank finishes while reducing cycle times on industrial production runs.</p>.

<p>Driven by an all-geared hardened headstock and a dedicated hydraulic power pack, the machine operates smoothly across a threading capacity range from 1/2" (12 mm) up to 2.1/2" (65 mm). The self-opening tangential chaser die head automatically pops open the moment the programmed thread length is reached, enabling immediate rapid carriage return without dragging cutters back across the freshly cut threads.</p>

<h3>Key Features</h3>

<ul>

<li><strong>Hydraulic Pipe Clamping & Saddle Feed:</strong> Dual hydraulic cylinders actuate the self-centering vise jaws and drive the saddle feed with steady, vibration-free thrust.</li>

<li><strong>Self-Opening Tangential Die Head:</strong> Die head releases cutters instantly at the exact end of thread travel, eliminating cutter chipping during carriage reverse.</li>

<li><strong>Hardened Headstock Gearing:</strong> Case-hardened EN-24 alloy steel gears running in a continuous splash oil bath deliver high torque at low rotational speeds (30, 60, 90 RPM).</li>

<li><strong>Integrated PLC / HMI Touchscreen:</strong> Allows the operator to set thread length, cycle timing, and feed parameters with automated cycle initiation.</li>

<li><strong>Heavy Cast-Iron Bed Base:</strong> Graded cast iron construction dampens cutting vibrations, prolonging tangential chaser cutting edge life.</li>

<li><strong>Flood Coolant Flushing:</strong> High-capacity motorized gear pump floods the cutting zone to dissipate heat and flush steel chips continuously.</li>

</ul>

<h3>Applications</h3>
