Q: How to adjust focus distance of laser marking machine

Adjusting the laser focal length is an important skill in the operation of the laser marking machine, which directly affects the marking effect and quality. The following are some commonly used methods for adjusting the laser focal length:

### 1. Continuous light test method

1. **Draw a figure**:

- Draw a square or circle of about one centimeter on the marking software and fill it normally.

2. **Set parameters**:

- Adjust the laser energy to a larger value and use a low frequency as much as possible.

- Check the continuous marking function.

3. **Test focal length**:

- Place a metal business card or other obstruction at the laser projection position on the product surface.

- Continuously emit light for marking, shake the Y-axis up and down until the laser acts on the metal business card with the strongest energy, the clearest sound, and the brightest color, which is the focal length position.

4. **Record distance**:

- Use a ruler to measure the distance from the galvanometer lens to the surface of the object, and record this distance as a fixed value.

- The next time you mark the same object, just adjust the height of the galvanometer to the surface of the object to that value.

### 2. Manual adjustment of focal length

1. **Set parameters**:
- Set appropriate parameters according to the specific requirements of the laser marking machine, such as rate, power, frequency, etc.
- Select the filling method as needed, such as bow filling, filling density and other parameters also need to be set accordingly.

2. **Place sample**:
- Place a thin metal business card or other obstruction on the object to be engraved to help determine the engraving position and as a reference for adjusting the focal length.

3. **Red light assisted focus**:
- Use the red light assisted focus function to adjust the lens distance by manually shaking the adjustment lever.
- Observe the position of the red light spot. When the two red light spots coincide, it is the correct focal length position.

4. **Engrave and adjust**:
- Turn on the engraving function and rotate the roller to adjust the marking height during the engraving process.
- Adjust while engraving until the light spot is the strongest and the buzzing sound is the loudest, then determine the correct focal length.

### 3. Double red light point value method

1. **Hardware configuration**:
- This method requires the device itself to have the hardware configuration of red light positioning.
- Install one or two oblique red lights next to the galvanometer or galvanometer.

2. **Adjust focal length**:
- Using the principle of right triangle, find the other right angle side of the focal length surface through a fixed right angle side and two overlapping hypotenuses.
- When the two red light indicator points overlap, it is the focal length position.

### 4. Automatic focusing system

1. **System installation**:
- Install the automatic focusing system on the laser marking machine, which usually includes a visual positioning system.

2. **Automatic focusing**:
- Automatic focusing marking is achieved through the visual positioning system, and the focal length can be automatically adjusted even if there is a slight difference in the thickness of the workpiece.

### Notes

- **Maintain consistency**: When adjusting the focal length, the same height value should be used to ensure that the laser focus is always on the surface of the workpiece.
- **Laser safety**: During operation, be sure to follow the safety operating procedures of the laser equipment, avoid looking directly at the laser, and ensure the safety of the operator.
- **Equipment differences**: Since laser marking machines of different brands and models may differ in design and operation, adjustments must be made according to the requirements of the specific equipment in actual operation.

In summary, adjusting the laser focal length requires comprehensive consideration of multiple factors and methods, and choosing the most suitable adjustment method according to the specific situation.

Q: What’s laser marking machine?

A: The laser marking machine, also regarded as a laser etching machine, is undoubtedly one of the best marking tools available. It can be applied to etch a wide range of materials and leave permanent marks on their surfaces. Laser marking technology produces high-quality and easy-to-read permanent marks which are reliable to manufacturers and customers. These marks are hardly damaged by these laser marking machines, even in extreme working conditions, such as vapors, high temperatures, etc. Compared with traditional marking methods, laser marking is a non-contact process along with lower operating costs and material costs. In addition, by means of a laser marker, some other useful information can be added to your products, including codes, serial numbers, and texts, etc.

Application:

The 20W machine is mainly used for surface marking of plastic, stainless steel, aluminum and so on.

If the customer wants to engrave deeply, then a 30W machine will be a better choice. For all materials, aluminum is the easiest to achieve deep engraving.

If you want to do deep marking on brass, silver, or gold or cut it, you need to choose the 50watt. As you know, these materials are high-reflective materials. If you choose the lower watt, the marking speed is low.

Q: Which Materials Can Be Laser Marked?

A: As is known, we can engrave most metals thanks to Fiber Laser marking machines.  However,  this does not mean that these machines only mark metals. We have fiber laser,UV laser,CO₂ laser ,they can mark plastics (pet bottles), ceramics (marbles), leather,cloth,glass,silicon with laser marking method.

Q: How do i choose laser source?Fiber ,UV or CO₂ ?

A: Fiber laser is suitable for metal and some plastic,UV laser is suitable for plastic ,CO2 laser is suitable for wood,cloth,plastic, etc.

Q: 20W 30W 50W laser marking machine different

A: ① 30w is more durable than 20w , and 50w is more durable than 30w

     ② if marking same content on same materials, 50w marking speed is faster than 20w/ 30w

     ③ if marking same depth on same material, 50w marking time is shorter than 20w/ 30w

      In brief, big power laser machine have greater efficiency.

Q: What’s the biggest marking area of laser marking machine

A: 30*30mm~500*500m optional. 
  • Small Working Area (50mm x 50mm to 100mm x 100mm)

    • Applications: Ideal for small parts, jewelry, electronics, or tools.
    • Materials: Typically used for marking small items such as metal parts, plastic components, and delicate objects.
  • Medium Working Area (150mm x 150mm to 200mm x 200mm)

    • Applications: Used for larger parts or where more detailed marking is required, such as in the automotive or medical industries.
    • Materials: Suitable for a wide range of materials including metals, plastics, ceramics, and composites.
  • Large Working Area (300mm x 300mm to 500mm x 500mm or more)

    • Applications: Suited for marking large items like sheet metal, large panels, or industrial components.
    • Materials: Typically used for industrial applications where larger parts or surfaces need to be marked with barcodes, logos, or serial numbers.

Q: What is the depth of laser mark?

A: A mark's depth depends on the laser marker type, the parameters used to create the mark and the target material.

For example, the depth of a single mark on plastic can be easily controlled and varied (from a few microns to over 1mm). However, metal marks are typically only 10-90 μm deep, so deep engraving takes much longer to accomplish.

Thus, a wide variety of marking styles are available by simply changing the laser power and marking speed.

Q: Do you accept sample marking test?

A: Yes, the sample test is free. If you have a marking request, please send the marking file in DXF/AI format and the sample to us. We will conduct free testing, share the marking cycle time and video with you, and return the sample for your review."
