摘要： PROBLEM TO BE SOLVED: To precisely detect whether or not such a small-diameter tool as that smaller than 0.5 mm in diameter is broken by a non-contacting inspection method that hardly causes the breakage of the tool even in an environment in which mist such as that of cutting oil is spattered.SOLUTION: An injection nozzle 1 and a receiving nozzle 2 are opposed to each other. A certain amount of air is jetted in vain from the injection nozzle 1 before installing a tool 10 in an inspection section A. Then, a flow volume threshold is set based on an air volume Q1 taken into the receiving nozzle 2 at this time. The flow volume threshold is set desirably at each inspection. Thereafter, the tool 10 is inserted into the inspection section A, and in this state, a certain volume of air is jetted again from the injection nozzle 1. Then, the air volume Q2 jetted at this time is compared with the flow volume threshold, thereby deciding whether or not an inspection target tool is broken.
