在增产节約运动中,我厂工人和技术人員利用高速钢廢刀具加入少量的硅、錳和硬質合金碎片,鑄造成功了合金车刀。經使用証明,这种鑄造合金車刀硬度高、耐磨,能进行高速切削。切削性能比高速钢好,比BK硬質合金稍差。这种車刀的成本很低,比購买高速鋼刀要便宜86％,它的缺点是脆性较大。这里把我們的初步經驗介紹如下: 设备 鑄造合金車刀需用以下这些設备和用品: 1.坩鍋爐一个(如图一),內装10号石墨
In the campaign to increase production and save energy, our factory workers and technicians use high-speed steel scrap cutting tools to join a small amount of silicon, manganese and carbide fragments, casting a successful alloy lathe. The use of proof, this cast alloy turning tool high hardness, wear-resistant, high-speed cutting. Cutting performance is better than high-speed steel, slightly worse than the BK carbide. The cost of such a turning tool is very low, 86% cheaper than the purchase of a high-speed steel knife, and its disadvantage is greater brittleness. Our initial experience here is as follows: Equipment Casting alloy knife need the following equipment and supplies: 1. Crucible boiler (Figure 1), built-in graphite No. 10
