Cold Saw Grinding Machine

Designed to maintain strict dimensional tolerances under continuous multi-shift production, the Cold Saw Grinding Machine provides <p>The Cold Saw Grinding Machine by National Cutting Tools is a specialized blade sharpening and re-toothing machine tool designed for resharpening high-speed steel (HSS) and carbide-tipped (TCT) circular saw blades used in metal cutting cold saws. In pipe fabrication shops, scaffolding plants, and steel service centers, dull cold saw blades cause blade deflection, burred pipe cuts, and premature tooth breakage; this machine restores factory-original tooth geometry, rake angles, and clearance bevels.</p>.

<p>Featuring an adjustable blade indexing mechanism and a high-speed grinding spindle, the machine sharpens straight teeth, curved teeth, and alternating high-low (triple chip) tooth profiles across blade diameters from 200 mm to 500 mm. Precision cam control or automated mechanical indexers ensure that every tooth is ground to identical height and bevel angles, extending saw blade life by multiple regrind cycles.</p>

<h3>Key Features</h3>

<ul>

<li><strong>High-Low Tooth Sharpening (HZ/BW):</strong> Precisely grinds alternating rougher (high) and finisher (low) tooth bevels for smooth chip evacuation in cold saws.</li>

<li><strong>Adjustable Blade Diameter Range:</strong> Universal mounting arbor handles circular saw blades from 200 mm up to 500 mm diameter.</li>

<li><strong>Precision Tooth Indexing Pawl:</strong> Automatic mechanical indexer advances blade tooth-by-tooth with positive lock at each tooth face.</li>

<li><strong>Adjustable Rake & Clearance Angles:</strong> Allows fine setting of cutting rake angles from 0 to 25 degrees to match mild steel, stainless, or non-ferrous sawing.</li>

<li><strong>Rigid Cast-Iron Frame:</strong> Heavy base dampens grinding vibrations to produce razor-sharp tooth cutting edges.</li>

<li><strong>Integrated Coolant Delivery:</strong> Flushes grinding swarf and prevents tooth overheating and temper loss during re-toothing passes.</li>

</ul>
