CUTTING TIP OF MILLING CUTTER AND MILLING CUTTER WITH SUCH TIP Russian patent published in 1999 - IPC

FIELD: double-side cutting tip for finish milling. SUBSTANCE: double-side cutting tip has two identical plane-parallel main surfaces turned by 90 degrees one relative to another. Each main surface has four working cutting angles. Two tapered surfaces adjoin to each cutting angle; said surfaces are inclined by predetermined angle relative to plane of main surface. Four lateral surfaces are inclined in pairs by predetermined angle for providing positive geometry of cutting. Due to use of two tapered surfaces, edge shearing of milled part is significantly reduced. EFFECT: minimized number and size of edge shearing, enhanced quality of milled surface, lowered axial pressure of milling tool onto part. 8 cl, 8 dwg, 2 ex
