How does the lens affact?—Tony

How does the lens affact?

Lens size

When customer purchase a laser marking machine, the one important question is the lens deciding. Why this is so important? It is because the machine will only with one lens.  So that means if you choose one which is  incorrect. Then your machine may not able to achieve what you want it to do. So in usual, there are these model below:

50 * 50mm, 110 * 110mm, 175 * 175mm, 200 * 200mm, 300 * 300mm.

The lens‘ price are same. So there are lots of customers are willing to choose bigger size. Because the model defined by working area. The customers who want the biggest one was thinking that might process bigger stuff. But is the idea correct?

Definitely no, I always say that there is not a machine could do anything for you.

How to choose lens?

First you need to know what is the maximum size you need to mark for your object. If the object is only 100*100mm, Then you choose 110*110mm. Do not choose bigger size. Because laser is a kind of light. If you do want to engraving, deep engraving, or even cutting. The lens you choose bigger, it means the laser from two sides are weaker.

When the scanning area reaches a certain level, the light spot diameter is very large, not sufficiently fine. Because the spot becomes large,the distortion increases,so the power density of laser decreases rapidly, and the working distance lengthens. This inevitably leads to the loss of laser energy. So it doesn’t conducive to precision machining.

By the way, when customers choosing it, the customers also need to consider the overall configuration. If you already decide to purchase a 20w machine. But you still want a 300*300mm lens. Then the power of laser is very weak.

So  in short, to choose best one for a machine, you need to consider it carefully.

Features of metal fiber laser marking machine-Wendy

First of all, many people are not very understanding of the metal fiber laser marking machine.  Because it is not clear their own industry will not be used. In fact, laser marking machine is widely used in terms of concept. Useful Marking can be used to laser marking machine.

Then, the so-called fiber laser marking machine is the type of marking machine. Fiber laser  is with small size (no water cooling device, the use of air-cooled). Good beam quality (basic mode), maintenance-free features, mainly by the laser. The beam quality, the output center of 1064nm, the whole life of about 100,000 hours. Relative to other types of laser marking life more long. Electro-optical conversion efficiency of 28% or more.  Relative to other types of laser marking machine 2% -10% conversion efficiency advantages. Performance and other aspects of energy saving and environmental protection.

Features of metal laser marking machine

1.  Can be a variety of metal, non-metallic materials for processing. Especially for high hardness, high melting point, brittle material marking even more advantages.

2. Belong to non-contact processing, does not damage the product, no tool wear, marking quality is good.

3.  Thin laser beam, processing material consumption is small, processing heat-affected zone small.

4. High processing efficiency, the use of computer control, easy to automate.

Application areas in metal laser marking machine

Future advantages in metal laser marking machine

(1) The advantages of miniaturization and intensification resulting from the low manufacturing cost, mature technology and optical fiber reluctance of glass optical fiber;

(2) The glass fiber does not require the exact phase match of the incident pump light like the crystal, which is due to the wide absorption band due to the non-uniform broadening caused by Stark splitting of the glass substrate;

(3) glass material has a very low volume area ratio, heat dissipation, low loss, so the higher conversion efficiency, low laser threshold;

(4) output laser wavelength and more: This is because the rare earth ion level is very rich and its rare earth ion species as much;

(5) Tunable: As the rare earth ion energy level and wide glass fiber fluorescence spectrum wider.

(6) Since there is no optical lens in the cavity of the fiber laser, it has the advantages of adjustment-free, maintenance-free and high stability.

(7) fiber export, making the laser can easily handle a variety of multi-dimensional arbitrary space processing applications, the mechanical system design has become very simple.

(8) Competent for harsh working environment, dust, shock, shock, humidity, temperature has a high tolerance.

(9) without thermoelectric cooling and water cooling, just simple air-cooled.

(10) High electro-optical efficiency: The comprehensive electro-optical efficiency is over 20%, which greatly saves power consumption during operation and saves running costs. High-power, commercial fiber lasers are six kilowatts.

Routine maintenance

Firstly, when the machine is not working, should cut off the marking machine and computer power. When the machine is not working, the lens cover lens cover to prevent dust pollution of optical lenses.

Secondly, the work of the local circuit was high voltage state, non-professionals, do not overhaul the boot, so as to avoid electric shock accident. Any failure of the machine should immediately cut off the power.

Thirdly, equipment for a long time, the dust in the air will be adsorbed on the surface of the lower end of the focusing lens. The lighter will reduce the power of the laser, affecting the marking effect. if the focusing mirror surface is contaminated, remove the focusing mirror to clean the lower surface. Be careful to remove the focusing lens, be careful not to damage or fall. At the same time, do not touch the focusing mirror surface with your hands or other objects. In the marking machine work process, not move the marking machine, so as not to damage the machine.

In general,  marking machine do not cover the pile or put other items, so as not to affect the cooling effect of the metal laser marking machine.

Seals marking by fiber laser marking machine-Wendy

Seals marking fiber laser marking Machine

Following are samples of seals marking by fiber laser marking machine.

 

Now i would like to introduce you our newest model of laser engraving machine in 2018.

It equips with newest laser technology and advanced screen. It will extend the using life of laser machine.  And it will become easier to control.

Excellent beam quality

The optical fiber laser uses the medium mixed yb double-clad fiber with resonant cavity length.

So the beam quality is very good. And M2 value is 1.1. The output flare diameter can achieve 10 microns.

Excellent beam quality can ensure that optical fiber laser marking machine can get in a variety of material satisfying marking effects.

Meanwhile it is widely applied in most metal marking industries (such as brass, titanium, steel, iron, aluminum and so on)

and non metal materials like cloth, fabric, PVC, MDF, leather, acrylic, plastic and etc.

Laser long service life

Optical fiber laser marking machine use 1064 nm laser diode. So its average working hours can up to 100000 hours.

Small and exquisite Volume , applicable in the bad environment

Optical fiber surface area/volume ratio is high. And it is also good cooling effect. Meanwhile it does not need huge water cooling system and just simple air cooling.

So it can be running in bad conditions, such as high impact, high vibration, high temperature, dirt under the conditions of the normal operation.

Free maintenance operation

Optical fiber laser does not need for any maintenance (not including adjust or clean lens)

By the way, we are looking for partners and distributors of laser marking, cutting, welding and cleaning in global.

More details will be updated soon. Your bookmark will be the biggest encourage for me.
