PURPOSE:To improve cutting efficiency of a tool for a fragile material like a ceramic molded material or gel coating resin, by electrodepositing a hard abrasive grain of diamond and CBN or the like on the milling tool. CONSTITUTION:A milling tool cutting edge part 1 in a formed cutter 5, gluing a hard abrasive grain 2 of diamond, CBN, etc. to adhere by the plating method, forms a plated layer 3. A milling tool, worsening roughness of a cut surface if the abrasive grain is in a large size while decreasing a tool life if the grain is in a small size, obtains a good result for the size of about #80-#400. The tool obtains a good result for the abrasive grain embedding rate of about 70% or more. Further, the abrasive grain can use also Al2O3, SiC, etc. in addition to the above described in accordance with a use. |
