| Japanese Patent H 7-229612 No. 2899865 Grinding Tools for Burring |
|||
|---|---|---|---|
| Product Explanation | Application: These tools are used for removing the burrs created on the inside of the product (at intersecting holes, etc.) when metal products are machined (especially when drilling holes) and for finish machining. Effect: One tool can be used for the rough grinding to remove the burrs created and for finish grinding on the inside of cylindrical metal products to ensure both accurate rough grinding and smooth finish grinding without the labor of having to change tools during the process to make burr removal simple and fast and thereby provide high utility value and superior effectiveness. |

| Japanese Patent H 11-308808 No. Grinding Tools for Burring |
|||
|---|---|---|---|
| Product Explanation | Application: These tools are used for removing the burrs created during on the inside of the product (especially when drilling holes) when metal products are machined. Effect: (1) Twisting the tips of the metal wires maintains the metal wire strength and since there are no connections it also reduces the cost of manufacturing. (2) Unlike conventional burring brushes, products with small outside diameters can also be processed. |

| Japanese Patent H 11-308806 Grinding Tools (burring brushes, capped brush combination brushes) |
|||
|---|---|---|---|
| Product Explanation | Application: This tool uses a cap material to prevent scratching due to contact of the work by the tip of the brush core material. Effect: A cap material with brush bristles is attached to the tip of twisted or other brushes to prevent the brush core material and work from making direct contact. Product Explanation |

| Japanese Patent H 11-326975 Grinding Brushes |
|||
|---|---|---|---|
| Product Explanation | Application: These tools are used for removing the burrs created on the inside of the product (especially when drilling holes) when metal products are machined. Effect: (1) Twisting the tips of the metal wires maintains the metal wire strength and since there are no connections it also reduces the cost of manufacturing. (2) In addition, embedding the brush wire material in the holding body makes it possible to polish while burring. |

| Japanese Patent H 11-357086 Special Twisted Brushes |
|||
|---|---|---|---|
| Product Explanation | Application: This is a twisted brush for burring and polishing the inside of through holes in machined work. Effect: (1) The edge formed on the circumference of each brush part repeatedly strikes the machined work to improve the grinding/polishing effect to reduce the working time and labor. (2) Changing the brush material of the brush parts is very effective for machined work made of compound materials or those requiring a change in the type of processing, such as partial polishing. (3) The chips generated during grinding fall into the gap area and are pulled out from the processing space together with the brush to improve the finish inside the machined hole. |

| Japanese Patent 2000-385715 Brush Wire Specially Shaped Material (Plastic) |
|||
|---|---|---|---|
| Product Explanation | Application: These brush materials contain one, two, or more types of inorganic powders mixed in. Effect: The properties of the metal and the properties of the inorganic powder work together to provide a good grinding/polishing effect and efficient burr removal. Product Explanation |

| Japanese Patent 2000-190596 Brush Wire Specially Shaped Material (Metal wire) |
|||
|---|---|---|---|
| Product Explanation | Application: These brush materials contain one, two, or more types of inorganic powders mixed in. Effect: The properties of the metal and the properties of the inorganic powder work together to provide a good grinding/polishing effect and efficient burr removal. Product Explanation |

| Japanese Patent 2000-205595 Twisted brushes for very small diameter holes |
|||
|---|---|---|---|
| Product Explanation | Application: These twisted brushes make it easy to polish or otherwise process the inside of very small diameter pipe or holes. Effect: One strand of wire material is used to hold the brush material to make it possible to manufacture a brush with an outside diameter of less thanφ1 mm (0.2φ to 0.9φ), which has not been possible before. |
