Ancient drill – “bow roller”. Drilling technology has a long history. Archaeologists have discovered that in 4000 BC, human beings invented the device for drilling holes. The ancients erected a beam on two pillars, then hung a rotating cone downward from the beam, and then twisted the cone with bowstring to drive the cone to rotate so that it could punch holes in wood and stone. Soon afterwards, a drilling tool called a “wheelbarrow” was designed, which also uses elastic bowstring to rotate the cone.
The first drilling machine (Whitworth, 1862). Before and after 1850, German Marty G Noni first made a twist drill for metal drilling. At the International Fair in London, England, in 1862, Whitworth, an Englishman, exhibited a power-driven drilling machine for iron racks, which became the prototype of modern drilling machines.
Later, a variety of drilling machines appeared one after another, such as rocker drilling machine, drilling machine equipped with automatic tool feeding mechanism, multi-axis drilling machine that can drill multiple holes at the same time. Thanks to improvements in tool materials and drill bits and the use of electric motors, large, high-performance drilling machines were finally made.
