5 Pieces Basic Information for Our China CO2 Laser Engraving Machine.

1. What is the maximum depth of laser tube in 40W, 50W, 60W? 
Take acrylic for an example, the cutting depth of 40W laser tube  at full power is 3 to 4 millimeters while 50W is 4 or 5 millimeters and 60W CO2 laser engraving machine can get high to 10  millimeters. 

2. Why we need  the air pump to get the temperature of engraving area down?
When a CO2 laser engraver machine is working,  the temperature of the area is being engraving will get higher and higher, in case of fire,  a high quality CO2 laser engraving machine should be equipped with a air pump, and this air pump  produces cool air continuously to get the temperature down to make sure no fire will happen. 
And also this device can prevent high temperature of the Laser and prolong the laser life.  

3. What the positioning red light can do when use a CO2 laser cutting machine? 

Actually,  the positioning red light and the laser head are fastened together and move together during work. When testing the laser to adjust the red cursor and laser spot to coincide together. 
And the positioning red light is used to decide the engraving point  where to begin the engraving. 
4. Why we need an open cover protection? 
As we know, the emitted laser will do harm to human body if we open the cover of a working CO2 laser engraver.  So we need an open cover protection , once we open the cover of the machine, the machine will stop power supplying.

What Decide the Engraving Depth and Engraving Time of Our Small 3D CO2 DIY Laser Engraver?

As we known, CO2 laser engraver is much faster than China Mini CNC Engraving Machine, but it can not engrave hard materials such as aluminum, copper, brass and any metallic materials, because the melting points of metallic material are too high. 
Generally speaking, CO2 laser engraver can be widely used to cut or engrave materials such as acryl, timber, leather, plastic, glass, organic glass, PVC material, cloth, rubber, bamboo, jade and so on. 
Many customers asked ushow depth we can engrave and how long it will take when we use a CO2 3D laser engraver? 

Today, let China-CNCrouter.com share some information about aboved questions. 

First, there are three factors decide the engraving depth of the CO2 laser engraver. 
a. The hardness of the materials. The harder the material, the thinner the CO2 laser engraver can cut. 

b. The power of the laser tube of the CO2 DIY laser engraver. 40W, 50W, 60W, 80W CO2 laser engraver are with much different depth, the bigger the power laser tube, the thicker the machine can engrave. 

c. The engraving speed of the CO2 laser engraving machine. This can be adjusted by users. The higher speed, the deeper it can engrave. 

Second, there are two factors decide the time spent on engraving 
a.The size of the product for engraving. If the size bigger, the time for engraving will be longer. 

b. The working speed of the  laser engraver. We can adjust by two ways, one through adjusting laser tube power on machine control panel, the other is to adjust the X, Y, Z speed through software.

How Does A 3D CO2 Laser Engraving Machine Work?

The CO2 laser engraving machine is much more special than China Mini CNC engraving machine because of its three systems and working principle diagram.
Laser engraving machine has three systems. The first one is control system which controls the movement of the laser head. The second one is laser output system that is formed by laser power supply and laser tube. The last one is light path system, made up by mirror and focus lamp.
It is important to know the structure of the CO2 3D laser engraving machine before showing the working principle diagram. 
The working principle diagram can be divided into two parts.
First of all, before engraving we shall import the engraving documents into the software. Datum will be transmitted to motherboard by USB. At this time, the motherboard will outgo two kinds of signals. The first signal is for laser movement which will be transmitted to step motor by circuit.

When the step motor receives the signal it will start a mobile workforce. The second signal will be transmitted to the power supply. Then the power supply will emit electricity to laser tube as soon as it receives the signal. On the meanwhile, the laser tube emits the laser engraving objects.
That’s a complete working principle diagram of a China 3D laser Engraving Machine .

China-CNCrouter.com is a professional China laser engraving machine Supplier , any question, please kindly contact with us.

Why the Laser Tubes of the Desktop CO2 Mini Laser Engraver Got Broken and How to Check?

Before answering these questions, we shall give a brief introduction of the CO2 Mini Laser Engraver.
The CO2 Mini Laser Engraver machine has three systems. The first one is control system which controls the movement of the laser head. The second one is laser output system that is formed by laser power supply and laser tube. The last one is light path system, made up by mirror and focus lamp. The laser tube is the one of the most important parts of laser engraving machine and is used for transferring laser.
Here are the reasons why the laser tube got broken? The first cause is that the laser tube is made by glass, it is fragile than common materials, so it might be broken during transportation. When the truck involves in traffic jam or crush, it might get damaged. The second reason is that 50w laser tube has its own life for 1000 to 1500 hours while 60w macro laser tube is 3500 hours.
After discussing the reasons, the next step is about how to check whether laser tube is broken or not. First of all, check whether the laser tube is cracked. If the laser tube is cracked, it is a signal that it’s broken. On the meanwhile, press the test key, laser tube is broken if its red light isn’t flushing.
As a leading China laser engraving machine Supplier, we make every effort to provide the best products and service to all of our customers. What makes us different from other companies is that we can offer many professional technical skills to customers in order to help them to manage the machine. 

What Materials Can Be Engraved By Our Mini Desktop CO2 3D Laser Engraving Machine?
