刀具特点(见图):1.刀片材料为YG6,型号为B205。2.刀刃是椭圆曲线,刃口是锐刃;前面是圆柱体的斜截平面,可用手工磨成;后面是圆柱面,在外圆磨床上磨出来。这样一来,刀刃各点的四个基本切削角度(前角γ、后角α、偏角φ和斜角λ)都各不相同了,而这些角又可通过旋转φ10、φ20配合部分得到任意调整。这把刀具的“基本特点”是曲线刀刃加大前角(γ=35°～50°),适
Tool features (see photo): 1. The blade material is YG6, model B205.2. The blade is an elliptical curve, the edge is a sharp edge; front oblique cross-section of the cylinder can be manually ground into; behind the cylindrical surface, Grind on a cylindrical grinding machine. In this way, the four basic cutting angles (rake angle γ, relief angle α, declination angle φ and skew angle λ) at each point of the knife edge are different from each other, and these angles can be obtained by rotating the φ10, φ20 mating portions arbitrarily Adjustment. The “basic feature” of this tool is that the curvilinear blade increases the rake angle (γ = 35 ° ~ 50 °)
