Abstract: A multi-function cutting machine includes a cutting tool for cutting a workpiece, a feeder for selectively feeding a gas or fluid to through a longitudinal passage of the cutting tool to the workpiece to carry away cutting chips from the workpiece, a first laser beam and a second laser beam respectively projected through the passage of the cutting tool onto the workpiece, and a detection control device for receiving the reflective light wave of the second laser beam reflected by the workpiece for measuring the working depth of the cutting tool.

Abstract: A probe for providing micro liquid drops including a main rod, a limiting portion and a probe tip portion is disclosed. At least one guiding flow way and several storing recesses are disposed on the conical outer surface of the probe tip portion. Each storing recess has a volume that is larger than the volume of the guiding flow way. Also, under the gravity and capillarity effect, the output speed is controlled by the number, size and shape of the guiding flow ways and the storing recesses so that each probe structure is strong, the liquid storing capacity is high, its liquid output is stable, it is easier to manufacture the guiding flow ways, and it is easy to clean.
