The bed of our general deep hole drilling and boring machine is composed of multi-section beds. The bed body is a three-sided closed structure with oblique ribs and has good rigidity. The bed guide rail has rectangular shape, high bearing capacity and good guiding precision. The guide rail has been quenched and has high wear resistance. The feed screw is installed in the groove of the guide rail of the deep hole drilling and boring machine body. The lead screw is composed of many segments.
The two ends are supported by brackets, and the middle is supported by two trawlers. The trawler can move along the guide rail at the bottom of the groove. The traveling and staying time are controlled by the pull plate and roller on the trawler part. There is a T-groove on the front wall of the bed, on which the fixed-range seat of the boring rod bracket and the fixed-range seat of the trawl board are installed, so as to control the position of the trawl board and the boring rod bracket. The front wall of the bed is equipped with racks, which mesh with the gears of the manual device for moving the center frame, bracket and boring rod bracket.
