(1)步进钻床电机的驱动　　根据步进电机的工作原理，我们知道步进电机的角位移量与指令脉冲的个数成正比，旋转方向与通电方向有关。因此步进电机的驱动电路，必须能控制步进电机各相励磁绕组电信号的通电变化频率、次数和通电顺序。这个工作由脉冲分配器和功率放大器来完成通过脉冲指令，按一定顺序导通或截止功率放大器，使电机相应的励磁绕组通电或断电的装置叫脉冲分配器，也叫环形分配器。它由门电路、触发器等基本逻辑功能元件组成。步进电机的正转与反转，由方向指令控制。步进电机的转角与转速分别由指令脉冲的频率与数量决定。　　(2)步进钻床电机的工作原理　　尽管步进电机种类很多，但钻床基本原理实质都是一致的。现以三相反应式步进电机为例，说明其工作原理。　　在步进电机定子上有3对磁极，上面绕有励磁绕组，分别称为A相、8相和C相.转子上带有等距小齿(图中有4个齿)。如果先将A相加上电脉冲，则转子1、3两齿被磁极A吸引而与该磁极对齐，而后再将B相加上电脉冲，则已相磁极将离它最近的2、4齿吸引过去，这样转子就沿逆时针方向转过30°。同样的道理，如将C相加上电脉冲，则转子又转过30°。之后再将A相加上电脉冲，转子继续转过30°。如此这样.按A→B→C→A…依次通电，步进电机就按逆时针方向一步一步转动。如果按A→C→H→A……的顺序通电，则步进电机将按顺时针方向转动。

手动工具，是五金行业的一种分类。根据用途可分为扳手类、钳子类、螺丝刀类、卷尺类、锤子类、套筒类、切削类、剪刀类、组套类、以及辅助类如工具车等，每种类别均有不同的型号。其相对于电动工具而言，主要是借助于手来拧动或实力于工具。一般应用在特殊环境下作业，如易燃、易爆、极端恶劣条件中。大多数人在使用手动工具之前并未受过训练，因此导致意外伤害频繁。根据统计资料显示，每年因为手动工具使用不当所引起的伤害，占所有意外伤害发生原因的7%至8%。

为确保镀层粘附性，热镀铝锌合金镀层板生产一般需采用炉外清洗，即在退火炉前设置电解脱脂清洗段。退火：热镀铝锌合金镀层板的退火与普通热镀锌板相比有两个问题需考虑：一是对LCAK钢如何实现在线过时效处理，因其过时效的温度为3～35℃，而带钢入锌锅温度要求大于55℃；二是由于其镀液温度比锌的熔点高出2℃左右，易引起炉鼻处锌的蒸发，这种锌蒸汽附着在带钢上，就会使产品产生漏镀缺陷，因而需确保炉内强的还原性气氛和严格控制炉鼻处的零点温度。
