Built-in positioning machine tool casting slide

Abstract

The utility model discloses a built -in positioning's machine tool casting slide. Including slide body, bearing seat and casting body, the casting body is located between slide body and bearing seat, be equipped with a plurality of inserts on the slide body and bearing seat, one end of the insert is located in the casting body. A built -in positioning's machine tool casting slide of the utility model solves the in the casting forming process of slide, because mineral material can produce shrinkage force when solidifying, simultaneously, the temperature difference of various parts leads to the generation of residual stress in the cooling process, these factors interact, and the technical problem of extremely easy bearing seat inclination.
