1kw/3kw/5kw Square Pipe Fiber Laser Cutting Machine

Quare pipe fiber laser cutting machine use a low-maintenance solid-state laser source to generate a laser beam that is delivered through fiber optic cable to the laser cutting head.  This fiber transfers the beam with a beam quality tailored for cutting metal.

Best fiber laser cutting machines are becoming more and more popular in metal processing and manufacturing. During use, various fiber laser cutting problems will occur, such as laser head problems, electrical problems, laser problems, water-cooled machine problems, etc. Senfeng leiming after-sales engineer sorted out many fiber laser cutting common problems and solutions.This article mainly explains electrical laser cutting problems.

Fiber laser machine is out of power Cause of failure

1. Phase sequence error

2. The voltage is insufficient, the accessories are damaged, and the circuit is not fastened firmly

Solution

Solution 1: Check the phase sequence and change any two live wires to change the phase sequence

Solution 2: Check the main power output , the fire and the live wire voltage, the three live wires and the neutral voltage respectively, check the voltage of the phase sequence protection switch/three relays, the 220 behind the main AC contactor controls the pull-in voltage, and AC contact Whether the main line of the inverter is loose or whether the main AC contactor is burned out

The servo is out of power Failure reason

1. Emergency stop press

2. The switch is not turned on, the wiring is not fastened firmly, the switch position of different models is different, please judge according to the model

3. Damaged accessories

4. Servo damage

Solution

Solution 1: Check whether the emergency stop switch is turned on (the old G machine also has an emergency stop switch on the left side of the beam)

Solution 2: FL.GMAHM.AM detects whether the electric lock, servo switch, and the relay that controls the servo AC contact pull-in are energized (the wire number is generally 5 and 24V-), whether the upper control line of the AC contact is energized, and whether it is wired If it is not connected properly, whether the relay is on. You can replace it with other 24V relays to determine if it is good or bad, and whether the AC contactor is damaged

Solution 3: H opens the servo circuit breaker and there is electricity, measure whether the circuit breaker has electricity and whether it is normal

Solution 4: Check whether the voltage of the electronic transformer is normal

Solution 5: Replace the servo

No power for laser water cooling

cause of issue

1. The external switch is damaged and the circuit is blocked

2. Internal problems of the water-cooled machine

Solution

Solution 1: Check the voltage at the terminal, the voltage of the circuit breaker, whether the main power supply of the machine, the voltage stabilizer or the field voltage is normal, whether the switch is damaged, replace the switch recovery circuit

Solution 2: Contact SENFENG engineers

Laser cutting is achieved by heating the material using a focused laser beam.  As the material melts, it is effectively removed either by gas jet or vaporization, thus creating a cut kerf.  There are 3 basic types of laser cutting methods:

Laser Cutting Techniques

In Fusion Cutting, the laser beam is coaxially combined with an inert gas such as nitrogen or argon. The heat produced by the laser beam creates a molten layer that is ejected down through the kerf by pressurized gas from the nozzle. Fusion cutting may be used for cutting mild steels up to 25 mm thick.

Flame cutting, also called reactive cutting, utilizes a laser beam coupled with oxygen gas or air to heat the substrate to its ignition temperature. While the heat produced by the laser beam melts the surface, the gas exothermically reacts with the substrate and creates an additional source of heat to form an oxide layer or slag. As the gas jet ejects the slag from the bottom surface of the substrate, it produces a cut kerf. Flame cutting is often used for cutting alloy steel such as mild steel and thicknesses up to 40 mm at relatively fast processing speeds.

Sublimation or evaporative cutting is usually processed by heating the layer to the vaporization point. This cutting method is typically used for materials with low vaporization temperatures such as polymers, wood and organic materials.
