下料是异型石材加工的步，首先选择质地优良、尺寸合适的荒料进行下料。下料基本上采用圆盘式金刚石锯、金刚石串珠绳锯机。下料形状有板料和块料，板料有平板和圆弧板。使用的工具主要是大直径的金刚石圆锯片和金刚石串珠绳。成形即指异型石材的轮廓加工。异型石材的轮廓多种多样，有花线、圆弧板、柱座、柱头、平面雕刻、立体雕刻等。使用设备也是多种多样，有*的数控设备、液压仿形设备、光电仿形设备、立式车床、卧式车床、手拉磨床、钻床等。

不仅如此，还要对蓄电池进行保养，测量电解液的比重，及时去掉灰尘污物与氧化物，使电池线与蓄电池接柱安装牢固，以增加柴油机启动时的电流。对策四：合理的使用新、旧设备进入冬季避免使用老、旧设备，尽量使用性能好的设备。由于老、旧设备使用年限较长，活塞环与气缸壁之间的间隙变大，气缸密封性能差，在启动时气体渗漏多，降低了压缩空气的压力，缸套内的压缩比达不到，柴油进缸内燃烧不起来，造成起车时冒蓝烟，车就是起不来，造成启动困难。
