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.

About this item

• [12 pcs in 6Grits White Corundum Sharpening Stone] Different grit for most polishing and sharpening works. Grits: 320 #, 400 #, 600 #, 800 #, 1000 #, 1200 # .
• [Material White corundum oil stone Description ] The stone is sintered by high temperature and appears to be red, with a tight and delicate structure and high hardness and strength. When grinding the workpiece, it can keep the sharp edge good finish, high durability, similar hardness to white corundum, good toughness, and usually has better grinding performance than white corundum.
• [Use]It is suitable for grinding tool steel, alloy steel and quenched steel, especially for grinding various tools, gauges and instrument parts with high requirements of finish or tool sharpening and repairing workpieces.It can be applied to printing stone,Knives,and other metal surface polishing and sharpening.
• [Notes of Use the Sharpening Stone] 1.When sharpening the knife fully use the entire surface of the oil stone, to maintain the consistency of the surface of the oil stone. 2.The use of attention to protect the oil stone, avoid falling from a high place. 3.With the use of sharpening oil for better results.
• [Portable Size sharpening stone] Product Size: 150 * 12 * 3mm(5.9x0.47x0.12Inch),package included 12 pcs whetstone set ,Small and portable, The type allows you to polish small parts and small corners easily.

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.

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.
