在法国进行技术考察期间,对机床主要零件——齿轮的材料及工艺进行了调查,现介绍如下。一、材料与热处理里内公司生产的各类机床(从加工宽度500毫米的小型数显铣刨床到加工宽度为5.7米的重型数控龙门铣镗床)齿轮的材料大都选用具有较高性能的镍铬钢(法国牌号10NC
During the technical investigation in France, the main parts of the machine tool - gear materials and processes were investigated, are presented below. I. Materials and Heat Treatment The types of machine tools that Rieter manufactures (from a small digital planer with a width of 500 mm to a heavy duty CNC gantry boring machine with a width of 5.7 m) are mostly made of nickel-chromium Steel (French brand 10NC
