Current, as the development of mechanical industry, taller and taller to product quality and the demand that produce efficiency. Accordingly, tool maker must design the assorted cutting tool with advanced and reasonable, complex tall coefficient, satisfy the requirement of the market. R is cylindrical assorted milling cutter is me the groove that the factory machines east wind 4G diesel locomotive to join body staff for plant of peony river engine (width is 64mm, deepness 25mm, two end have R18mm) and design. Also apply to engine plant to machine congener spare parts at the same time, use accordingly extensive, have very good development perspective. To plant of peony river engine order goods, below the circumstance that all does not have a data domestic and internationally, we go up in the foundation of survey, the technology that offers according to the user asks with me the process capability of the factory undertook feasibility analyses research. This workpiece penetration of a cutting tool is deep, cutting bizygomatic breadth, particularly tall to demand of performance of cutting tool cutting, if the shovel is made or use whole common straight tine milling of 3 blade milling cutter, penetration of a cutting tool fights muscularity, long after grinding, assure to machine width hard, cannot satisfy treatment requirement. Accordingly, we designed R cylindrical assorted milling cutter. This milling cutter is combined by two knives and become, have on blade of outer round cutting left, right 10 ° helix angle (blade dip) , combine epigenesis herringbone, make milling cutter gets power even, cutting is smooth. Improved cutting condition greatly thereby, raised cutting rate, raised workpiece surface surface roughness, after using, can repair repeatedly grind. In the meantime, in add among two knives adjust mat, can assure to be machined the width dimension of the spare parts, raise the utilization rate of cutting tool. Combined-type R is cylindrical milling cutter external diameter is 130mm, public errand of diameter of every milling cutter after combination 0. 1mm, the be patient of on blade of milling cutter cutting is more than 0.
The columnar first flank of 1mm, bearing end panel internally the end panel of aperture axes is jumpy tolerancepublic errand 0.
02mm, requirement of requirement of the others technology and cylindrical milling cutter is identical, satisfied user requirement on the technology thereby. The change that my factory adopts form of ministry of milling cutter blade, inside Kong Duojian chamfer (3 key) , blade of the cutting after the design of conterminous end panel that trisect protruding groove combines makes this cutting tool is combined is ceaseless blade, make sure treatment face is a plane thereby, without knife mark.
