Laser marking machine marking depth problem has been plaguing customers

Laser marking machine marking depth problem has always plagued customers

Laser marking machine technology belongs to a non-contact marking method, which has many incomparable advantages with traditional processing methods, and is now widely used Laser-marked hardware and keyboards, and use lasers to engrave works of art on materials such as bamboo and wood, such as computer-controlled technology, high efficiency, fast rhythm, fine laser marking, laser marking machine laser marking Features: high speed, smooth incision, generally no need for subsequent processing, small heat-affected zone of cutting, small plate deformation, narrow slit (0.1mm~0.3mm), no mechanical stress in the incision, no shearing burr, high machining accuracy, repeatable Good performance, no damage to the surface of the material, CNC programming, can process any plan, can cut the whole board with a large format, no need to open a mold, economical and time-saving.

At present, in the total sales of laser processing systems in the world, laser marking machines are second only to laser cutting machines, occupying the second place. In recent years, they are close to the sales of laser cutting machines, each accounting for the total On the contrary, the sales of laser marking machines have always accounted for more than 50% of domestic laser processing sales, occupying the domestic market in a large range and greatly expanding the industrial field of application. , It can be said that the application area of u200bu200blaser marking machines is much wider than that of foreign laser marking machines. The materials of marking objects can be all kinds of metals and non-metals. I believe that in the next few years, domestic laser marking machines will rely on their own advantages. Better service In the processing market, quickly improve the competitiveness of the market.

As a country with the fastest development in the rise, China has become the focus of the world economically. The production market of domestic laser marking machine manufacturers is also the same. It has developed very well since entering the Chinese market. It uses the laser beam to evaporate the surface material of the workpiece to expose the deep material, or cause the chemical and physical changes of the surface material to engrave traces. Due to the simple processing of the laser equipment and the exquisite effect, the laser The technology has been widely used in China.

The laser marking machine uses a laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or Through the chemical and physical changes of the surface material caused by light energy, traces are 'engraved

The problem of marking depth of laser marking machine has been plaguing many customers, and it is one of the most common problems in laser engraving. Laser introduces the marking depth of laser marking machine for you The reasons for not being deep enough are as follows: .

1. Whether the laser output power of the laser marking machine meets the requirements.

2. Whether the turn-off power of the acousto-optic switch meets the requirements.

3. Whether the optical path adjustment is accurate.

4. Whether the position and direction of the beam expander are accurate.

5. Whether the surface of the laser marking machine lens is polluted or not.

6. Whether the workpiece surface is on the focal plane.

7. Whether the output DC voltage of the laser power supply 28V has dropped, resulting in a lower laser output power.

Why does the motor heat up? In fact, any motor will heat up, but the heat level is different. Generally, the heat level of a metal laser marking machine is very low, and generally there is no It is different for the laser marking machine, because the laser marking machine is easy to heat up during the working process, which is also determined by its performance. You should know that the stability of the current directly affects the operation of the motor. If the current is not standard The DC or sine wave will also produce harmonic losses. The iron core has a hysteresis eddy current effect, and losses will also occur in the alternating magnetic field. The size is related to the material, current, frequency, and voltage, which is called iron loss.

Copper loss and iron loss will be manifested in the form of heat, which affects the efficiency of the motor, and more electrical energy is converted into heat, so In the laser industry, if the current is unstable, the working efficiency of the metal laser marking machine will be greatly reduced, resulting in a serious problem of motor heating of the metal laser marking machine. The motor burns out and the whole is in a state of paralysis, so Minsheng Laser reminds customers that when the motor heats up, it needs to be handled carefully to avoid unnecessary losses.

In fact, any motor will heat up, but the heat level is different. Generally, the heat level of a metal marking machine is very low, and generally it will not have any effect. For laser marking The machine is different, because the laser marking machine is easy to heat up during the working process, which is also determined by its performance.

Everyone should know that if the current is not a standard DC or sine wave, harmonic losses will also occur. The iron core has a hysteresis eddy current effect, and losses will also occur in an alternating magnetic field. , its size is related to material, current, frequency, voltage, which is called iron loss, copper loss and iron loss will be manifested in the form of heat, thus affecting the efficiency of the motor, more electrical energy is converted into heat energy, greatly reducing the laser The working efficiency of the standard machine.
