How do laser cutter nozzles of different powers be selected?
Laser head nozzle in the laser cutting process, through the collection of capacitive signals, through the ceramic ring to transmit it to the signal processor, so as to maintain the
Fiber Laser Cutting Machine in the cutting process laser head to the distance tracking of the workpiece, guide the gas smoothly through the cut workpiece, and near the nozzle outlet to form a high pressure, speed up cutting speed, take away slag, protect the laser head internal lenses.
Type of nozzle
General laser cutting nozzles are divided into single, double-layer, single-layer nozzle for melting cutting, that is, nitrogen as auxiliary gas, usually used to cut stainless steel, aluminum alloy, brass, etc. ;
General laser cutting nozzles are divided into single and double layers
Nozzle size selection
The size of the nozzle diameter determines the shape of the air flow into the incision, the area of gas diffusion and the flow rate of the gas, thus affecting the removal of molten material and the stability of cutting. The high air flow into the incision, the high speed, the proper position of the workpiece in the air flow, the stronger the ability to spray to remove molten material. The user selects the size of the nozzle according to the power of the laser used and the thickness of the metal sheet cut. Theoretically, the thicker the plate, the larger the nozzle should be used, the greater the pressure of the proportional valve setting, the greater the flow, to ensure the pressure, in order to cut out the normal section effect.
Different power nozzle options
Laser power ≤ 6000w
Cutting carbon steel, nozzle size diameter is generally double-layer S1.0-5.0E;
Cutting stainless steel, the selection of common specifications WPCT single-layer nozzle;
Laser power ≥ 6000w
Cutting carbon steel, 10-25mm carbon steel bright surface cutting, select nozzle specification diameter is generally double-layer high-speed E-type S1.21 to 1.8E;
Cutting stainless steel, choose the common specification WPCT single layer nozzle.
