Silver is one of the common jewelry materials nowadays. Customers like it since it is affordable and does not tarnish readily. But silver is also a problematic metal material to cut. So we are trying to choose a laser cutting machine for silver with more than 500 W. So how to choose a suitable laser cutting machine for our business?
How to use a laser cutter machine to cut silver?
Silver is an excellent conductor of heat. You can choose a laser cutting machine for silver with 800W or more, which will easily cut silver. Other metals and jewels can also be cut with this equipment. If you need to engrave for a long time, you can also choose the industrial silver laser engraving machine.
What types of metals can be laser cut?
All metals and jewelry, precious and non-precious, can be laser cut. Most of the SILVER laser marking machines can easily cut up to 2mm thickness. You can use them for inscriptions, dog tags, rings, necklaces, etc.
Different metal properties use different laser cutting processes, including the metals we commonly see.
- Gold: Easier to cut because gold is relatively soft while having good thermal conductivity.
- Silver: Silver is characterized by retaining the heat from the laser, which can make the cutting process more difficult. We need to choose a bracket or other equipment specifically for heat dissipation. This will prevent the laser cutting machine for silver from bending during the process.
- Stainless steel: The gold and silver laser engraving machine works at a fast cutting speed to cut stainless steel. This will ensure that the stainless steel cutting process does not appear in the secondary welding. Because stainless steel will splash if the laser moves too slowly, and the degree of splash will be more serious.
Common problems when laser cutting silver
Silver will inevitably have problems during engraving or cutting as a heat-absorbing metal. If we don’t handle it correctly, it could result in significant financial loss as well as personal injury.
Laser head
Sometimes there may be no laser emission from the laser tube. We need to check whether the laser is connected to the power supply. And also, check to see if the wire is loose or broken. If not, you must determine whether the laser tube is malfunctioning. If it is defective, you need to replace the laser tube with a new one.
Material waste
There will be some material loss in the laser cutting and engraving process. We must first check whether the cutting table is correctly positioned to avoid material waste.
Engraving distortion
Of course, many factors cause engraving or cutting distortion. An unaligned laser ray path may cause this. We need to adjust the laser light path. If the pulley is badly worn, replace it with a new one. Or poor contact with the memory card can also cause engraving distortion. This is because we need to re-install and replace the memory card.
Insufficient cutting/engraving depth
The user should adjust the output power using the control panel if the laser’s output power is too low. You should modify the software to slow down the cutting or engraving if it goes too quickly.
Cutting Speed
To lessen the possibility of the process cutting out, the maximum feed rate that it can handle is lowered by about 10% to 15%. Thus, a high level of beam energy is applied to the material with the highest reflectivity.
Focus position
The focal point position is selected for cutting and piercing as close to the top surface as the cut quality permits. By doing this, the amount of surface material that first interacts with the beam is reduced. This maximizes the power density of the shaft and thus speeds up the melting rate.
