Needless to say at that price I went home with 3 different ones. It was quite worn but sharpened up with my small diamond stone and did the job. I did most of them in my drill press but moved over to the mill as my drill press won't get the center holes.

不用说在这个价格我到家里， 3种不同的，这是相当破旧，但激化了与我的小钻石石和没有工作，我没有他们大多在我的钻床，但移动到轧机作为我的钻床将得不到中心孔。

At present, there are drilling more than 150 plants, with an annual output of various drilling about 1 million units, export over 20 million units, the drilling of speed through a pulley shift to resolve the pagoda, the governor need to stop the process, open the protective Enclosures, manual transmission, and other procedures, the process cumbersome and poor security, and is governing, not transferred to the spindle speed corresponding to the different materials of various aperture drilling at the best speed, the production efficiency is low.

目前，全国有钻床厂150多家，年产各种钻床100万台左右，出口20多万台，这些钻床的变速都是通过一对宝塔皮带轮换档解决的，调速过程需要停车、打开防护罩，手工换档等程序，操作过程繁琐且安全性差，并且是有级调速，不易使主轴转速调到对应于不同材质的各种孔径钻削时的最佳转速，因此生产效率也低。
