Definition and Working Principle of Laser Engraving Machine
Laser engraving machine is a device that uses laser beam to engrave patterns or text on the surface of different materials. Its working principle is to use laser beam to irradiate the surface of the material with high energy, so that the surface of the material is heated, vaporized or melted, thereby forming the desired pattern or text.
Laser engraving machines are often used to make customized gifts, prizes or industrial products, as well as to make complex designs in many industries such as jewelry, electronics and manufacturing.
Features of Laser Engraving Machine
Precise focus
It can ensure that the laser beam can be accurately focused on the surface of the workpiece during the engraving process, thereby achieving precise engraving effects.
Multiple connection methods
Whether through USB interface, Wi-Fi connection or network connection, users can easily control the laser engraving machine for a more convenient operation experience.
Safety and reliability
By adopting various safety protection measures and reliable design solutions, the laser engraving machine can ensure the safety of users and equipment while ensuring work efficiency.
Large working area
Applicable to various working areas from 80*80mm to 1300x2500mm, effectively improving production efficiency.
Wide range of applications
Applicable to materials such as acrylic, metal, two-color board, density board, leather, cold silk, rubber, wood, bamboo products, plexiglass, plastic, marble, jade, crystal, etc.
Rich application scenarios
It can be applied to advertising, handicrafts, leather, toys, clothing, models, architectural decoration, computer embroidery cutting, packaging and papermaking, etc.
Applicability of Laser Engraving Machine
Diode laser engraving machine has a wavelength of about 455nm~1064nm. It is ideal for cutting and engraving non-metals, such as wood, leather, acrylic, etc.
The wavelength of CO2 laser engraving machine is about 10600 nm, which can be well absorbed by non-metallic materials, especially acrylic and transparent glass.
Infrared laser engraving machine can directly engrave and cut metals, including stainless steel, aluminum, copper, etc.
Clearly define the purpose of use
Before choosing an engraving machine, you must first clarify your purpose of use. Different materials have different absorption rates of lasers, and different engraving machines are suitable for different materials and application scenarios, so you need to choose an engraving machine suitable for specific materials:
- Personal enthusiasts: If you are just a personal enthusiast, you may need a small, affordable engraving machine to make some personalized small objects.
- Professional designer: If you are a professional designer, you may need an engraving machine with higher requirements for engraving accuracy, speed and area to make some artworks.
- Small-scale production: If you are a small business owner and need to produce small batches, you may need an engraving machine with medium power, good stability and long life.
In general, diode and CO2 laser engraving machines are suitable for non-metallic materials such as wood, leather, acrylic, etc. The price is relatively low, suitable for beginners and small-scale production. Infrared laser engraving machines can cut and engrave metals, suitable for people who have engraving needs for metals.
Considerations
Engraving power & Engraving speed
Laser power directly affects the depth and speed of engraving. Choose the right laser power based on your needs. Generally speaking, the higher the power, the better the engraving effect, but the higher the price. Speed affects the accuracy of laser cutting. The following is an example of a parameter chart related to laser power and maximum cutting thickness:
Engraving area
The engraving area is an important factor in determining the productivity and adaptability of a laser engraver.
It directly affects the size of the material you can handle, as well as the scope of the machine. For example, jewelry and other small metal objects are suitable for smaller engraving areas, while wider engraving areas are suitable for large projects such as signs and markings for large industrial equipment.
Therefore, when choosing a laser engraver, you should choose a machine with an appropriate engraving area based on the size of the object you want to engrave. Popular working area sizes range from 75mm x 75mm to 300mm x 300mm. Choosing the right engraving area can ensure that your project can be completed efficiently and accurately.
Software compatibility
The software compatibility of the engraving machine involves whether the machine can work seamlessly with your design software and whether it supports the file format you need. For example, some engraving machines may be directly compatible with vector design software such as AutoCAD, Coreldraw, Photoshop, etc., which can greatly simplify the workflow and improve efficiency. In addition, some high-end engraving machines may also support specific software functions, such as automatic path optimization, speed control, etc., which can further improve the quality of engraving and production efficiency. Therefore, when choosing an engraving machine, be sure to confirm whether the machine is compatible with your design software and supports the functions you need.
Budget
Budget is the first consideration when choosing an engraving machine. Different engraving machines have different prices, ranging from a few hundred euros to tens of thousands of euros. You need to decide what price range to buy an engraving machine based on your financial situation and expected return on investment. At the same time, you should also consider long-term operating costs, including power consumption, consumables replacement, etc.
Maintenance and repair
The maintenance and repair costs of the engraving machine are also an important consideration. Some machines may require more frequent maintenance, which will increase additional costs. Choosing machines that are easy to maintain and repair can reduce future troubles and expenses.
Accessory functions
Accessory functions refer to additional functions that come with the engraving machine, such as autofocus, multi-axis control, rotary chuck, honeycomb table, etc. These accessories can improve the accuracy and efficiency of engraving, expand the diversity of engraved objects, help better heat dissipation, etc., but they may also increase the cost of the machine. Choose whether you need these accessory functions according to your specific needs.
Ease of use
Ease of use involves the machine’s operating interface and user experience. Choosing an engraving machine with an intuitive interface and easy operation can improve work efficiency and reduce learning costs.
Connectivity
Connectivity refers to the ability of the engraving machine to connect with other devices (such as computers, printers, etc.). Good connectivity can easily transfer design files and improve the efficiency of the workflow.
Safety
Safety is a factor that must be considered for any mechanical equipment. Make sure the engraving machine meets safety standards, such as emergency stop buttons, protective covers, tilt protection, child locks, etc., to protect the safety of operators.
Noise
Engraving machines make noise when working, especially when working for long periods of time, noise may become a problem. Choosing a machine with a lower noise level can create a more comfortable working environment.
Fume and purification
Fume and dust may be generated during the engraving process, which not only affects air quality but may also cause health hazards. Choosing an engraving machine equipped with a fume extraction system can reduce these risks.
Conclusion
Choosing the right engraving machine for you is a decision that requires comprehensive consideration of multiple factors. You can find the engraving machine that best suits you by clarifying the purpose of use, choosing the type of laser, considering the engraving material, determining the engraving area, evaluating the engraving accuracy, considering the machine power, software and control system, budget and return on investment, after-sales service and technical support, as well as user reviews and brand reputation. Hope this blog can help you make a wise choice and make your creativity and production more efficient and accurate.
