我厂在各种不同的机床上(如车、铣、刨床等)推广应用科列索夫车刀法以来,它给金属切削方面开辟了一个新的方向,使机床效率发挥,进行强力切削而提高生产率,并且提高了产品质量及表面光洁度,其中以立铣床上(包括龙门刨改装的龙门铣)的应用尤为显著。例如第一金工车间的龙门铣利用科列索夫车刀法铣切机梁,提高切削效率400%。后来工人周三新同志在立铣床上推广发展科列索夫车刀,采用阶梯切削法铣切工字架条子,提高了切削效率300%。一、阶梯切削原理见[图一],在刀盘上装三把刀子,它们在圆周上各相距120°,而半径则不同(R_1>R_2>R_3,三者分别代表刀
Since our company promoted and applied Koletsov turning tool on various machine tools (such as car, milling, planer, etc.), it opened up a new direction for metal cutting and made the machine efficiency to be intensively cut Increase productivity, and improve product quality and surface finish, especially on vertical milling machines, including gantry-mounted gantry milling. For example, the first metalworking workshop gantry milling Kolevsdorf turning method milling machine beam, improve the cutting efficiency of 400%. Later, on Wednesday, the new workers promoted the development of Koleasov turning tools on vertical milling machines, and used stepped cutting methods to cut the I-frame sliver so as to increase the cutting efficiency by 300%. First, the ladder cutting principle see [Figure 1], mounted on the cutter three knives, which are 120 ° apart on the circumference, while the radius is different (R_1> R_2> R_3, respectively, three representatives of the knife
