The Two-in-One Polishing Slurry for Fiber Optic Connector End-Faces is a new type of polishing consumable specifically designed for polishing the end-faces of fiber optic connectors, particularly MPO/MT multi-fiber connectors. It combines the final two steps of the traditional polishing process — fiber protrusion and final polishing — into a single step, thereby simplifying the process, replacing imported precision polishing slurries, and reducing costs while improving efficiency.This product employs a unique formulation technology that uniformly disperses selected nano-scale abrasives and functional additives to form a stable suspension system, enabling high-efficiency polishing of the fiber ferrule end-face in a single process step.

A small bore punch die fabricated from YG8 cemented carbide (tungsten carbide) for a precision stamping manufacturer exhibits prominent machining textures and micro-scratches on its inner bore and end faces subsequent to WEDM and sinker EDM processing. The as-machined surface roughness measures roughly Ra 0.6 μm. These surface imperfections readily induce galling and burr formation on stamped components during production, leading to abbreviated die service life and inferior process yield. A high-throughput, consistent polishing process is thus in critical demand.Polishing cemented carbide via diamond polishing suspension constitutes a highly process-critical operation. Given the exceptional hardness of YG8 cemented carbide, only diamond abrasives possessing greater hardness are capable of delivering efficient stock removal and surface finishing on this substrate.Workpiece Technical ParametersSubstrate Material: YG8 cemented carbide (tungsten carbide)Pre-Polish Condition: WEDM / sinker EDM machined surface, Ra ≈ 0.6 μm, accompanied by residual machining textures and edge micro-chippingCustomer Performance Targets: Eliminate the surface damaged layer, achieve mirror-grade surface roughness, preserve tight dimensional tolerances, boost finished stamping part yield and extend die service lifespan

CD discs are primarily fabricated from soft polycarbonate (PC) plastic or glass substrates, topped with an aluminum reflective data coating. Laser data playback demands ultra-high standards for surface smoothness and flatness.Our custom CD polishing fluid represents the premium option for damage-free, durable CD surface finishing. Built on CMP (Chemical Mechanical Planarization) chemo-mechanical polishing mechanism, it effectively eliminates prevalent faults such as surface scratches, haze, disc skipping, choppy playback and laser reflection malfunction.For this polishing project, the customer implemented our recommended MYH-SOP315 CD-specialized polishing fluid. The product removes the flawed outer surface layer while offering full protection to the inner aluminum reflective film of CD media. No damage will be caused to the laser signal layer, completely resolving all surface-related defects encountered.
