我厂WD200型落地鏜床安装使用不久,立柱在床身上移动时就有微小的爬行現象,后来逐漸加剧为0.5～1毫米的間断冲击性爬行,并附有严重的振动声,鏜削平面出現振痕。因爬行消耗动力較大,拖板作5毫米╱分以下的低速移动时,电动机就不能轉动。我們先后組織了两次修理,由于爬行的原因是多方面的,故第一次仅对其中的部分因素进行了修理,修理后爬行情况虽有些改善,但未彻底解决,使用两三个月以后,立柱拖板爬行又恢复原状。为此,在总結第一次修理經驗的基础上,根据摸索到的有关爬行規律,針对爬行的 I plant WD200 floor boring machine installed soon after the column moving in the bed when there is a slight crawling phenomenon, and later gradually increased to 0.5 to 1 mm intermittent impact creep, accompanied by severe vibration sound boring plane vibration mark. Due to large crawling power consumption, carriage for 5 mm / min below the low-speed mobile, the motor can not be rotated. We organized two repairs in succession. Because of the many reasons for crawling, for the first time only some of the factors have been repaired. Although the crawling situation has been somewhat improved after the repairs, it has not been completely solved. After two or three months of use, , Column mop crawl and restitution. To this end, on the basis of summing up the experience of the first repairs, according to the crawling of the law of crawling, crawling
