The invention relates to a novel
machine tool
bed casting assembly which comprises an integrally cast
chassis base and an integrally cast working platform, wherein a plurality of T-shaped slots are arranged at the top of the working platform; a guide rail is arranged at the top of the
chassis base, a support is arranged in the center of the
chassis base, and an X-axis driving device connected with the working platform is arranged on the support; and a guide rail oil chamber is arranged at the bottom of the working platform, and the guide rail oil chamber is spaced on the guide rail. The novel
machine tool
bed casting assembly has the characteristics of reliable structure, good working stability, strong guide rail
impact resistance, difficulty in wearing and the like. Because pressure oil is introduced between the guide rail and the working platform contact surface, a moving part is slightly floated, the friction factor is extremely small, the transmission efficiency is very high, and the
crawling phenomenon can not occur during low-speed movement. Worms and gears are adopted for the X-axis transmission of the working platform, so that the working platform has the characteristics of large
transmission ratio, smooth transmission and small
noise. The novel
machine tool
bed casting assembly well solves the problems that the traditional working platform guide rail has poor
impact resistance, is not applicable to heavy-load
processing, is easy to wear and the like.
