In the production, the concentric holes on the wall of the box parts are often encountered. Due to the long size of the box and the precision requirements of the concentric holes, it cannot be processed once by the drill bit or the reamer. To this end, it is necessary to pass the rational design of the tooling to meet the production requirements. Figure 1 shows one such part produced by our factory, made of ZL102, processing two (?) 12mm holes and (?) 30mm counterbore. The technical requirements are as follows: the coaxiality error of the four holes is not more than 0.05 mm, and the parallelism error of the bottom surfaces of the two countersinks (?) 30 is not more than 0.03 mm. In order to ensure the machining accuracy requirements of the four holes in this process, we designed and manufactured a set of lathe fixtures to meet the production requirements, and the effect is very good.
