DRILLING MACHINES GENERAL INFORMATION Carnegie Mellon University

A drilling machine, called a drill press, is used to cut holes into or through metal, wood, or other materials (Figure 41). Drilling machines use a drilling tool that has cutting edges at its point. This cutting tool is held in the drill press by a chuck or Morse taper and is rotated and fed into the work at variable speeds.

Drilling | TRUMPF

Trepanning. Trepanning also uses multiple laser pulses to produce the hole. In this process, a pilot hole is first created using percussion drilling. Then the laser enlarges the pilot hole, moving over the workpiece in a series of increasingly larger circles. Most of the molten material is expelled downward through the hole.
