摘　　要：在制造大型卧式铣镗床中,其中一个重要部件——滑枕的前后轴承孔在加工过程中,由于其孔深,跨距大,同轴度、圆度精度要求高,靠机械加工成型还是一个较大难题。在借鉴国外一些经验后,采用了高精度定位胶,尝试了一种注胶成型滑枕前后轴承孔技术,结果取得了很好的效果,各项精度检测均达到了设计要求。In the manufacture of large horizontal milling- boring machine,the preparation of the front and rear bearing bore of the ram is difficult to rely on machining because of the hole depth,large wheelbase and the higher standard of concentricity and roundness. In the article,we successfully prepared it by means of injection molding using the high precision positioning adhesive,and the accuracy of detecting meets the design requirements.
