Punching machine is a kind of mechanical equipment that the punching die acts on the material after the raw materials are installed and driven by the power mechanism. Punching machine can carry out sheet metal processing, stamping, molding, embossing and other operations to force metal into the mold. Today, let's learn about the difference between punching machine, drilling machine and punch. < br style = "list style type: none;" / > & nbsp; & nbsp; punching machines and drilling machines: < br style = "list style type: none;" / > & nbsp; & nbsp; drilling is the process of drilling holes on processing materials with a drill bit, 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;" / > & nbsp; & nbsp; punching machines are suitable for processing soft materials because the holes drilled by the drilling machine will have burr and unevenness. < br style = "list style type: none;" / > & nbsp; & nbsp; drilling machines are suitable for machining hard materials, because the impact force of the punch often causes cracks in the processed materials. The processing objects of punch and punch press are similar to each other to a great extent. Punch can be divided into ordinary punch, fast punch, etc. because punch needs a feeding system, their volume is generally large. < br style = "list style type: none;" / > & nbsp; & nbsp; punching machine is a further development of punch, it solves the problem that punch needs independent feeding system, so its volume is small. The punching machine is divided into ordinary punching machine, automatic punching machine (also known as automatic positioning punching machine, automatic positioning punching machine), automatic punching machine, etc. The common punching machine has no automatic positioning system, which is equivalent to a small punch which solves the feeding problem. The automatic punching machine adds an automatic positioning system on the basis of the ordinary punching machine, which greatly improves the punching accuracy and speed. It can be understood as an automatic control high-precision small punch press.
