Operates at 2 lb pressure, 110 RPM, for 50 seconds per plate.</p>\n\n\n\n<p>Outcome: Establishes initial fiber alignment and eliminates major surface irregularities.</p>\n\n\n\n<p><strong>2、Pre-Finish Leveling with SC3 Lapping Film</strong></p>\n\n\n\n<p>Product: GRISH SC3 (3µm Silicon Carbide)</p>\n\n\n\n<p>Process: Refines the surface with DI water at 2 lb pressure and 130 RPM for 130 seconds, ensuring uniform fiber height.</p>\n\n\n\n<p>Outcome: Reduces micro-scratches and prepares the surface for final smoothing.</p>\n\n\n\n<p><strong>3、Smoothing and Geometry Control with PUMD Pad and AO Slurry</strong></p>\n\n\n\n<p>Product: PUMD Pad + AO-1-50B Slurry (Aluminum Oxide)</p>\n\n\n\n<p>Process: Operates at 5 lb pressure, 160 RPM, for 140 seconds. The slurry enhances material removal consistency while maintaining the 8° APC angle.</p>\n\n\n\n<p>Outcome: Achieves sub-micron surface roughness and tight geometric tolerances.</p>\n\n\n\n<p><strong>4、Final Finish with PUMZ Pad and CO Slurry</strong></p>\n\n\n\n<p>Product: PUMZ Pad + CO-1-30B Slurry (Colloidal Silica)</p>\n\n\n\n<p>Process: High-speed polishing (180 RPM) at 6 lb pressure for 40 seconds, delivering a scratch-free surface.</p>\n\n\n\n<p>Outcome: Produces a &lt;0.02µm roughness finish, minimizing back reflection and insertion loss.</p>\n\n\n\n<p>Advantages of the Grish Process:</p>\n\n\n\n<p>Time Efficiency: Total cycle time under 6 minutes per ferrule array.</p>\n\n\n\n<p>Consistency: Automated pressure and RPM settings ensure repeatable results across high-volume production.</p>\n\n\n\n<p>The<a href=\"https://grish.com/products/polishing-slurry/\" rel=\"noopener noreferrer\"> GRISH</a> polishing solution for MMC 16/24-fiber Single Mode APC TMT ferrules is a specialized product designed to meet the demanding requirements of modern fiber optic connectivity. </p>\n\n\n\n<p>By providing precise, consistent, and high-quality polishing, it plays a vital role in ensuring optimal performance and longevity of multi-fiber APC connectors in critical communication infrastructures.</p>\n\n\n\n\n",
