Abstract: To solve the problems that ultra-high precision rolling guides with motion parallelism less than 4 μm/m rely on imports, have limited supply channels and a single type in the development process of precision coordinate boring machines, it is very necessary to promote their domestic production process. Firstly, by combining the advantages of the sliding guide rail and rolling guide rail structures and designing an external adjustable preload device, a new type of double-V-type rolling guide rail structure was proposed and applied to the bed of the precision coordinate boring machine. Secondly, the structural design's feasibility was verified through finite element analysis. Finally, the processing, assembly process routes and inspection methods of the rolling guide rails were optimized, and the development from the design to the application of the rolling guide rails was completed, providing a new solution. After experimental measurement, the double-V-type rolling guide rails operate stably, with a rapid movement speed of up to 30 m/min. Their load-bearing capacity is greater than that of imported rolling linear guide rails of the same specification, and the motion parallelism reaches 3 μm/m.
