6.1 Ancient Drilling Machines – The “bow†drilling technique has a long history. Archaeologists have now discovered that in 4000 BC, humans invented devices for punching. The ancients placed a beam on the two columns, and then suspended a rotatable awl from the beam, and then used the bowstring to drive the awl to rotate, so that the wood stone could be punched. Soon, people also designed a perforating tool called "辘轳", which also uses a flexible bowstring to make the awl rotate.
6.2 The first drilling machine (Whitworth, 1862) By around 1850, the German Martignoni was the first to make a twist drill for metal punching; at the International Fair in London, England, 1862, UK Whitworth exhibited a drill press with a power-driven cast iron frame, which became the prototype of a modern drilling machine.
In the future, various drilling machines appeared one after another, including a radial drilling machine, a drilling machine equipped with an automatic feeding mechanism, and a multi-axis drilling machine capable of simultaneously punching a plurality of holes at the same time. Thanks to improvements in tool materials and drill bits, and the use of electric motors, large, high-performance drill presses were finally built.
