CERATON Japan Sharp Shield Fiber Oilstone Mold - Mirror Polished Ceramic Fiber Oilstone

CERATON ceramic fiber oilstones are high-precision mold polishing consumables, widely used in mold manufacturing, precision hardware, jade, and metal parts for fine grinding and mirror polishing. Utilizing a composite process of ceramic fiber and special resin, they possess core advantages such as high strength, high rigidity, high temperature resistance, excellent self-sharpening properties, and strong wear resistance, making them an upgraded alternative to traditional oilstones.

1. High Strength and Rigidity, Compression-Resistant and Wear-Resistant, Prevents Chipping: Utilizing high-performance ceramic fibers and a special resin impregnation and curing process, its tensile and compressive strength far exceeds that of traditional oilstones. It can withstand high-pressure grinding operations, effectively preventing chipping, breakage, and deformation during grinding, ensuring the smoothness and consistency of the workpiece surface.
2. High Temperature Resistance, Stable Performance at High Temperatures: The product exhibits excellent temperature resistance, maintaining stable physical properties even under high-temperature grinding environments. It will not soften, deform, or fail, ensuring consistently excellent cutting force and polishing effects during high-load, high-speed grinding operations. It is suitable for high-hardness materials such as stainless steel, cemented carbide, and mold steel.
3. Excellent Self-Sharpening Properties, Continuously Maintains a Sharp Cutting Edge: The unique ceramic fiber structure endows the product with excellent self-sharpening properties. During grinding, it automatically sheds dull abrasive grains, continuously exposing a fresh and sharp cutting edge. This significantly improves grinding efficiency and surface finish, reduces the inconvenience of frequent consumable replacements, and lowers overall operating costs.
4. Offers full grit coverage from coarse grinding (#180) to fine polishing (#1200), with each grit corresponding to a different color (e.g., #180 brown, #250 orange, #280 black, #400 blue, #700 yellow, #1000 white, #1200 red), facilitating quick identification and selection, and meeting the needs of all stages from deburring, coarse grinding, medium grinding to mirror polishing.
5. Dual-use (dry and wet), suitable for a wide range of scenarios. Supports both dry and wet grinding modes. Dry grinding produces less dust and is easy to operate; wet grinding effectively suppresses dust, reducing harm to the respiratory system, and minimizing workpiece deformation or burning caused by frictional heat. It is particularly suitable for surface treatment of precision molds, jade, metal parts, and other items requiring high gloss.

1. Mold Manufacturing:Suitable for the fine grinding and mirror polishing of various mold components—such as cavities, cores, parting lines, sliders, and ejector pins—in injection molds, die-casting molds, stamping molds, etc. This process enhances the mold's surface finish and extends its service life.
2. Precision Hardware: Ideal for deburring, chamfering, and polishing high-precision metal components, including precision hardware parts, medical instruments, watch components, and electronic parts. This ensures both the aesthetic appeal and functional quality of the finished products.
3. Jade & Jewelry: Suitable for the fine grinding and polishing of gemstones such as jade, emeralds, agate, and crystal. It enables a comprehensive, multi-stage finishing process—ranging from coarse grinding to mirror polishing—thereby enhancing the luster and intrinsic value of the gemstones.
4. Metalworking: Applicable to various metal materials—including stainless steel, aluminum alloys, copper alloys, and cemented carbides—for tasks such as oxide layer removal, weld scar removal, deburring, surface brushing (satin finishing), and mirror polishing. It is widely utilized across industries such as automotive, aerospace, and mechanical manufacturing.

1. Select the Correct Grit: Choose the appropriate grit size based on the workpiece material and specific grinding requirements. Adhere to the "coarse-to-fine" grinding principle; avoid using high-grit (fine) oilstones directly for coarse grinding, as this may reduce efficiency or damage the workpiece surface.
2. Control Grinding Pressure: Maintain uniform and moderate pressure during grinding. Avoid applying excessive force, which could lead to the oilstone breaking or cause surface defects on the workpiece, such as scratches or deformation.
3. Regularly Clean the Oilstone Surface: If the oilstone surface accumulates excessive debris or becomes clogged during grinding, use a soft-bristled brush or clean water to clean it. This restores its cutting performance and extends its service life.
4. Storage Environment:Store the oilstone in a dry, well-ventilated area away from direct sunlight to prevent moisture absorption, deformation, or degradation of performance.
5. Wear Protective Gear:Always wear appropriate personal protective equipment—such as safety glasses, face masks, and gloves—during grinding operations to prevent injury caused by dust inhalation or flying debris.
