一、前言指形铣刀一般根据所加工齿轮的具体情况自行设计,大模数齿轮加工中常采用指形铣刀,齿轮的参数为 Z=137,m=22,压力角α=20°。据此,我们拟设计指形铣刀,材料选用W18Cr4V。二、指形铣刀的材料及热处理工艺(一)铣刀材料的选择铣刀材料选择高速钢 W18Cr4V。W18Cr4V 是一种高合金工具钢,钢中含有 W、Mo、Cr、V 等合金元素。高速钢经过适当的热处理,可获得良好的
I. INTRODUCTION The finger cutter is generally designed according to the specific conditions of the gear being machined. The finger cutter is often used in the machining of large modulus gears. The parameters of the gear are Z = 137, m = 22 and the pressure angle α = 20 °. Accordingly, we intend to design finger cutter, material selection W18Cr4V. Second, the finger cutter material and heat treatment process (a) the choice of milling cutter material selection of high-speed steel cutter W18Cr4V. W18Cr4V is a high alloy tool steel, steel containing W, Mo, Cr, V and other alloying elements. High-speed steel after appropriate heat treatment, get good
