The principle of metal laser cutting machine to process metal sheet is to irradiate the sheet metal surface with high-energy laser and melt it rapidly at high temperature to achieve the purpose of cutting. During the processing of metal laser cutting machine, burning metal at high temperature will produce a small amount of exhaust gas. In order to ensure the personal safety of operators, there will be certain requirements for ventilation devices. Xinquanli Laser recommends two ventilation methods.

1. Exhaust treatment. Customers can choose whether to configure exhaust equipment when purchasing metal laser cutting machine. The general exhaust equipment is composed of four parts, namely, gas collecting hood, air duct, purification system and fan. It mainly uses air flow to control local exhaust gas, so that local workplaces will not be polluted by harmful substances and maintain a good air environment.

2. General ventilation. This method is a relatively simple and convenient operation method. It uses the air flow in the accelerated working area to reach the harmful gas in the dilution air. Generally, an axial flow fan is installed on the top of the workroom to exhaust the internal exhaust gas. This method is universal.

It is very important to choose the ventilation mode of the metal laser cutting machine reasonably. If there are too many equipment placed, Xinquanli Laser recommends to choose the exhaust treatment device.
