Porous drill

      The PQDKZ four-column semi-automatic multi-hole drilling machine mainly consists of components such as the gearbox, worktable, base, and columns. It is developed by our company based on the three-column and four-column multi-hole drills, utilizing modern computer technology for structural simulation and finite element analysis to optimize the design of the original gearbox and worktable, as well as upgrading the base and columns.

　　The PQDKZ four-column multi-hole drill is essential equipment in the automotive steel rim manufacturing industry for simultaneously drilling, reaming, and counterboring multiple bolt holes in wheel spokes.

　　The specialized multi-hole drill for wheel spokes is an indispensable piece of equipment in the production process of wheel spokes. It can enlarge bolt holes and counterbore them in one go. By pre-setting the diameter of the distribution circle and the number of bolt holes, it ensures that the positions of the spoke bolt holes meet design requirements. This equipment features high production efficiency, accurate positional dimensions, convenient operation, reliable performance, and simple maintenance. Through computer simulation and finite element analysis, it achieves high transmission efficiency with a reasonable overall design. It is an ideal device for processing spoke bolt holes.
