Maintaining a CO2 laser machines is actually pretty easy and it’s recommended that you spend time every day to keep it maintained, clean and functioning, as it should. It’s very important that you add the following to your daily or weekly maintenance checklist:
- Laser working gas and cutting gas pressure, if the gas pressure is not enough, you should replace it.
- Buttons such as X-axis zero, Y-axis zero, Z-axis zero, laser-ready status. The X-axis, Y-axis and Z-axis
- Chillers inside the circulating water level is sufficient, if not enough to be added in time.
- External light path of the road water leakage phenomenon.
- The lens.
If you spot any problems with any of these major parts, then you may want to call out an engineer to carry out repairs, but in most cases you should just need to carry out a ‘eye test’ and make sure everything is functioning as it should. If there are signs of wear then calling out an engineer to fit the correct replacement part is wise, and we recommend you do this early if you don’t want a problem later down the line to cause disruptions to your manufacturing line.
Diamond cutting and finishing has seen many advancements over the past 100 years. As technology has developed, so to has the ability for diamonds to be crafted.
The laser saw is one such technology that revolutionised diamond cutting when it was introduced in the 1930s. Many modern diamonds are cut using laser equipment which is far more accurate and efficient.
How Laser Sawing Works
The stone is mounted onto a dop so it can be directed through a laser beam. The burned graphite from the high-temperature laser leaves a black mark around both sides of the stone where the laser cut through. Because of this, these sides will then need to be polished. In certain cases, more weight is lost than would have been with conventional sawing.
The biggest advantage of laser cutting is the ability to cut with extreme precision. There is also no cutting edge to wear down, and lasers are less likely to warp the diamond because the heat is confined within a narrow space.
Laser cutting is carried out on a range of materials for many different purposes. While some of those functions have been discussed here, the specifics about how the laser beam itself is rarely discussed. So this post looks at just that, and how a laser cutting beam is focused.
A special lens is used to focus a beam, additionally a curved mirror can be used, but it all takes place in the laser cutting head.
The beam is precisely focused so that the shape of the focus spot and the density of the energy in that spot are perfectly round and consistent, whilst centred in the nozzle.
Focusing the large beam down to a single pinpoint causes the heat density to increase to a high degree. Much like using a magnifying glass to focus the sun’s rays onto a leaf, which can start a fire, Focusing 6 KWatts of energy into a single spot works in the same way.
Lasers are particularly suited for cutting the finest geometries with maximum precision and quality, which is something a cutting plotter is unable to do. Laser paper cutting machines not only allow for cutting even the most delicate paper constructions, but also the effortless engraving of logos or pictures.
An effective way of making the most out of laser cutting is to use specialised accessories. Including an optical detection system. An optical detection system is a camera system, which allows refined cutting of printed products. With a camera system, the contours of printed materials are cut perfectly. Using this system, even flexible materials are cut as accurately as possible.
No manual positioning is required, distortions in the impression are detected, and the cutting path is adapted automatically and appropriately. By combining the optical detection system with a laser cutting machine you can save on materials used and production costs.
Laser cutting is an intricate and unique way of creating tactile items. Part of the uniqueness comes from the different techniques and methods that can be incorporated into the production process. This post looks to outline some of the processes that can be used to create a unique design.
Masking involves protecting areas of an engraving, so as to not induce a smoking effect on the engraving. Laser engraving causes smoke to form. This smoke can then stain the edges of the engraved surface. So to avoid this, masking tape is used. This creates a cleaner finish over all.
A laser cutter should have some suggested settings for cutting or engraving different materials and different thicknesses. You should also be able to load these settings into your computer or laser and save them as pre-sets. Adjusting the pre-sets allows you to form a palette of different cutting techniques, allowing you to switch between them easily.
