一 引言 我厂从国外引进的A型泵制造技术具有国际先进水平,其中引进泵加工调节齿杆用的高精度大型梳形铣刀(图1)是本厂引进工装中的关键刀具,也是最复杂的引进工装之一。这种刀具外形大、重量重、结构复杂、精度要求高,专业刀具厂也无力承担加工。为了填补国内空白,我们克服了重重困难,终于攻克了这一难关。现将这种复杂刀具的设计与攻关制造情况作一简述。 I. INTRODUCTION Our A-type pump manufacturing technology introduced from abroad has the international advanced level. The introduction of the pump processing and adjusting the high-precision large-size comb type milling cutter (Figure 1) is the key tool in the factory to introduce the tooling, and also the most One of the complex introduction tooling. This tool shape large, heavy, complex structure, high precision, professional tool factory also unable to undertake processing. In order to fill the gap in our country, we overcame various difficulties and finally tackled this difficult situation. Now this complex tool design and research to create a brief situation.
