Abstract: An automatic drilling machine for simultaneously drilling at least two holes through a surface of a crosspiece. The machine comprises an automatic drilling unit having at least two tool holders, each one adapted for receiving a drilling tool. The automatic drilling unit has a cross-shaped channel configured to receive, at least partially, the crosspiece to be drilled inside the automatic drilling unit with. The tool holders are arranged, such as, when the drilling machine is mounted with the crosspiece to be drilled, the tool holders are positioned in accordance with the locations of the crosspiece where a hole is to be drilled.

Abstract: A drilling machine and a drilling method including drilling a first bore in a material with a drilling machine by applying a torque to a drilling tool for imparting a rotation at a first rotational speed to the drilling tool, and applying a thrust to the drilling tool for advancing the drilling tool at a first feed speed into the material, wherein a drilling parameter is measured while drilling the first bore, and a second rotational speed and a second feed speed are determined based on the drilling parameter, then drilling a second bore at the second rotational speed and at the second feed speed.
