Automatic Multi Spindle Drilling Machine

Designed to maintain strict dimensional tolerances under continuous multi-shift production, the Automatic Multi Spindle Drilling Machine provides <p>The Automatic Multi Spindle Drilling Machine is a high-production special-purpose machine engineered for automated, hands-off drilling of adjustment holes in scaffolding prop pipes. In large-scale prop manufacturing plants producing thousands of inner tubes per month, manual drill feeding causes operator fatigue, inconsistent feed rates, drill bit breakage, and burr formation that jams adjustment pins during site erection.</p>.

<p>This automated machine incorporates an electro-pneumatic or hydraulic quill feed system with rapid approach, controlled drilling feed, and rapid retract. Multiple heavy-duty drill spindles operate simultaneously through an adjustable gear transmission. An integrated indexing trolley advances the pipe automatically through programmed pitches, drilling the entire series of pin holes along a 3-meter prop in a continuous automated cycle.</p>

<h3>Key Features</h3>

<ul>

<li><strong>Automated Rapid-Feed Drilling Cycle:</strong> Fast approach to pipe surface, regulated feed through double walls, and instant retract minimize cycle time to under 8 seconds per pitch.</li>

<li><strong>Hydraulic or Pneumatic Pipe Clamping:</strong> Automatic self-centering V-jaws grip the pipe during the drilling stroke and release automatically for indexing.</li>

<li><strong>Programmable Linear Pipe Indexer:</strong> Optional motorized ball-screw indexer moves the pipe to successive hole locations at exact 100 mm or 125 mm steps.</li>

<li><strong>Infinitely Variable Feed Rate:</strong> Flow control valves allow fine tuning of drill feed to handle mild steel, high-tensile ST-52, or galvanized tube stock.</li>

<li><strong>High-Pressure Chip Flushing:</strong> Flood coolant system cools cutting edges and flushes chips out of the tube bore to prevent drill jamming.</li>

<li><strong>Centralized Electrical Control Console:</strong> Complete with emergency stop, cycle counter, manual jog controls, and thermal overload protection.</li>

</ul>
