Machine tool castings are mostly used on the bed. Its simple structure and good process performance facilitate the processing of the guide surface.
The horizontal bed of the machine tool casting is equipped with a horizontally placed tool post to improve the movement accuracy of the tool post. Generally it can be used for the layout of large CNC lathes or small precision CNC lathes. However, due to the small space in the lower part of the horizontal bed, chip removal is difficult.
Judging from the structural size, the horizontal placement of the tool holder makes the lateral size of the slide longer, which increases the structural size in the width direction of the machine tool.
