Abstract
To enable the amount of air capable of bringing smoke to the vicinity of a discharge opening of a gas discharge chamber to be sent into the gas discharge chamber. A cutting machine has gas discharge chambers arranged side by side by partitioning the inside of a table, blower openings each provided on one end side of a gas discharge chamber, gas discharge openings each provided on the other side of the gas discharge chamber, and fans for sending air, while moving to the outside of the table, to at least one gas discharge chamber from the blower opening of the gas discharge chamber and arranged in the direction of the movement. The fans are arranged at intervals such that two or more fans face the blower opening of one gas discharge chamber, and the two or more fans can simultaneously send air to the one gas discharge chamber.
