齿轮加工行业有12级精度的划分,从12级到1级,难度系数依次递增。一个普通的齿轮,它有57个齿,设计精度6级,徐强加工的齿轮,有417 个齿,精度要求达到4级。当精度等级在跨越的时候,一微米意味着就是一个精度等级,吹一口气就能把一微米吹掉。在此之前,如此大而精密的齿轮国内还不能生产,徐强接下了这个任务, 经过无数次精密计算和程序优化,巨大的齿轮零件终于在磨床上脱胎换骨。从此,在国内齿轮加工行业,便诞生了一个响当当的“名词”—— Gear processing industry has 12 levels of precision division, from 12 to 1, the difficulty of increasing in order. An ordinary gear, which has 57 teeth, 6 design accuracy, Xu Qiang processing gear, 417 teeth, accuracy requirements of 4. When the accuracy level is over, a micron means a level of precision that blows away a micron. Prior to this, such a large and sophisticated gear can not produce domestically, Xu Qiang took over this task, after countless precision calculations and program optimization, the huge gear parts finally grind on the grinder. Since then, in the domestic gear processing industry, they gave birth to a ringing “nouns”
