What is the frequency used for the laser marking machine?
The frequency setting on the laser marking machine is a very important parameter that mainly affects the effect and quality of laser marking. Frequency in the laser marking process usually refers to the pulse frequency of the laser beam, that is, the number of laser pulses emitted per second. The frequency setting directly affects the following aspects:
The main role of frequency
Marking speed:
A higher frequency means that the laser beam is emitted faster and can process more points per unit time, thereby increasing the speed of marking. This is very important when fast production is required.
Marking quality:
The frequency setting has a great impact on the fineness and clarity of the marking effect. A higher frequency can make the mark more uniform and detailed, but may cause the heat-affected zone to increase, thereby affecting the thermal damage of the material. The appropriate frequency can ensure the clarity and contrast of the mark.
Depth and contrast:
The frequency affects the energy density of the laser. The higher the frequency, the higher the energy output per unit time. This helps to produce deeper marks, especially on metal materials. Conversely, a lower frequency may be suitable for lighter marks or certain specific materials.
Material response:
Different materials may react differently to lasers. For example, metal and non-metal materials may require different frequency settings for the best marking effect. Higher frequencies may produce better results on some non-metal materials, while metal materials may need to be adjusted appropriately.
Marking mode:
Different marking modes (such as dot marking, line marking, fill marking, etc.) may require different frequency settings to suit design requirements and material characteristics.
Choice of common frequency settings
Metal materials: Usually higher frequencies (such as 20 kHz to 100 kHz) are selected to ensure clear and deep marking.
Non-metal materials: Frequency settings may vary depending on the material type, and usually lower frequencies (such as 5 kHz to 20 kHz) are suitable for certain plastics and wood to prevent overheating or damage to the material.
When using a laser marking machine, setting the frequency reasonably is an important step to optimize the marking effect. The frequency should be adjusted according to the marking material, the required marking effect and production efficiency to achieve the best effect.
