CNC Laser Cutters – How Laser Cutting Works

Lasers can be used for a lot of purposes. One of the best ways that they are being used is to cut metal plates. On stainless steel, aluminum plate, and mild steel, the process of laser cutting is very accurate, can yield excellent quality of cut, has a really small heat affect zone and small kerf width, and makes it possible to cut even small holes and the most intricate of shapes.element

Many people are already aware that LASER is basically an acronym, which stands for Light Amplification by Stimulated Emission of Radiation. However, how can light cut through steel plates?

How CNC Laser Cutters Work

The laser beam is a column of extremely high-intensity light of one color or wavelength. As for a typical CO2 laser, this wavelength is in the light spectrum’s infrared part, so this cannot be seen by the human naked eye. This beam is just around ¾ of one inch in diameter as this is traveling from the laser resonator. It then forms the beam through the beam path of the machine.

This can bounce in various directions with the help of mirrors or beam benders before finally focusing on the plate. This focused laser beam will go through the nozzle’s bore right before hitting the plate. Compressed gas will also flow through the nozzle bore such as nitrogen or oxygen.

A special lens can also be used to focus the laser beam or even a curved mirror, and this happens in the laser cutting head. This beam must be precisely Equipmentfocused so that the focus spot’s shape and the energy density in the spot are perfectly consistent and round, centered within the nozzle. Through focusing the large beam down to one pinpoint, there is extreme heat density at this spot. You can think of this as using the magnifying glass to focus the rays of the sun on a leaf, and how this can start a fire. Consider focusing 6 KWatts of energy to one spot, and you can then imagine how this spot is going to get.

This high power density can result in rapid heating, complete or partial vaporizing, and melting of the material. When you use it to cut mild steel, the laser beam’s heat is sufficient to start the usual oxyfuel process of burning, with the laser cutting gas being pure oxygen, similar to any oxyfuel torch. When cutting aluminum or stainless steel, the laser beam will just melt the material, while high-pressure nitrogen will be used for blowing out the molten metal from the kerf.

CNCOn a CNC laser cutter, the head of laser cutting can be moved over to the metal plate following the shape of the desired portion, which then cuts the part out the plate. The capacitive height control system can maintain a really accurate distance between the nozzle’s end and the plate that will be cut. This distance is essential since it will determine the location of the focal point in relation to the plate’s surface. The quality of cut can also be affected.

Roofing Tools

For those of you who are weekend warriors, you just may already have in your tool arsenal what you would need to tackle a project like a professional Baton Rouge roofer. What you are probably lacking is the knowledge that a professional has from working in the trade. Roofing should not be taken lightly as certain regulations must be closely adhered to so that the roof meets local ordinances and guidelines. If you are looking to tackle this type of project on your own you should definitely consult with a local roofer. He or she will know the local ordinances and of course will have the knowledge to help you out.

There are some basic tools that anyone, a DIYer or a pro, should definitely have in their possession long before the roofing project is started. Whether you are working on a roof for a shed or a house, the tools should be the same. Obviously, the roofing materials that you are using above the sheathing will also dictate what tools you should acquire.

Framing Square

A framing square is one of the most versatile and utilized tools in the construction industry. A framing square can help you layout and cut rafters, stringers for a staircase, check for square edges, or any number of uses. In the roofing world, a framing square is used for laying out and cutting common rafters. There is no roofer that could live without a quality framing square. It is recommended that you purchase a stainless steel model that will last for years.

Tape Measure

Anyone who has ever constructed anything has relied on a tape measure for precision measurements. Carpenters and woodworkers especially rely on a high-quality tape measure that is precise to a 1/16th or a 1/32nd of an inch. Anyone attempting to construct a roof on any scale will rely on their trusty tape measure.

Circular Saw

Another tool that is found in every roofer’s tool arsenal is the circular saw. One thing about a circular saw that you cannot do with a table saw is lift it above your head to make cuts. In years past a circular saw always required electricity for operation but in recent years, high-quality battery powered models have been developed that make the job easier for roofers while on the job site.

Jig Saw

A jig saw is a welcome addition to anyone’s tool chest. What is the most versatile aspect of the jig saw is that you can cut curves and a jig saw is lighter than a circular saw? One thing to consider is to purchase a high-quality model and you’ll find that the saw will cut through the wood like butter.

Hand Saw

Sometimes the best tool for the job is one that has been around for thousands of years. The hand saw dates back to the ancient Egyptians but its versatility shines through still today. Being able to quickly lop off the end of a board or make a notch for a birdsmouth in a common rafter without flipping a switch is what makes the common hand saw such an indispensable tool.

Hammer or Pneumatic Nailer

In years past, a simple hammer was always used to nail sheathing or shingles to a roof. But, in recent years, the pneumatic nailer has taken over this job, at least in the professional ranks. For the DIY roofer if you don’t want to invest in a pneumatic nailer you can certainly rent one on a daily basis from a local rental store. This handy tool will certainly make the job go much faster.

If you’re interested in doing your own roofing job, purchasing a few roofing tools is certainly a worthwhile investment. Maybe after you tackle this worthwhile undertaking you may just quit your day job and sign up to be a roofer.
