The working principle of the punching machine is that after the raw materials are installed on the work tool platform and driven by the power mechanism (manual drive or hydraulic drive), the punching die acts on the material to complete the punching operation. The following is a comparison of the differences between a down punching machine and a drilling machine: < br style = "list style type: none;" / > drilling is a process in which a drill bit is used to drill a hole on a processing material, while punching is a process in which the drill bit is punched down to form a hole by gravity. < br style = "list style type: none;" / > punching machine is suitable for processing soft materials, because the hole drilled by the drilling machine will have burr and unevenness. < br style = "list style type: none;" / > drilling machines are suitable for processing hard materials, because the impact force of the punch often causes cracks in the processed materials. < br style = "list style type: none;" / > the comparison between punching machine and drilling machine has been introduced above.
