PROBLEM TO BE SOLVED: To provide air blowing and mist collection systems in a machine tool in which a cutting scrap or a cutting fluid adhering to an object to be processed is removed by air blowing and mists generated during processing are collected in a processing chamber. SOLUTION: There is provided a machine tool in which an object to be processed is subjected to processing such as drilling and mists generated from a cutting fluid is adapted to collect with a mist collection system attached in a processing chamber, wherein a nozzle of an air blowing system 20 is provided on the portion for supporting a main spindle mounting a cutting tool; and a mist collection system 30 in which a disk type rotating brush 45 and an overshooting member 50 are fixed on a main spindle 41 disposed in a separation tank 31, an exhaust port of a cyclone 52 disposed in the downstream side of the overshooting member is disposed so as to connect to a suction pipe of a suction means 60, wherein a cutting scrap or a cutting fluid adhering to an object to be processed is blown off and removed by pressurized air ejecting from the nozzle and mists in air sucked from the processing chamber are separated in a separation tank.
