In the line of engineering, accuracy is of utmost importance. Laser cutting uses machines to help contour metal sheets to create complex looking exterior. The laser beam is around 2 mm in diameter and touches the surface to be cut at power ranging between 1000 to 2000 watts. The process is in fact complementary to the CNC/ Turret process. While the former is used for exterior molding, the latter is used for interiors.
Laser cutting depends extensively on data from CAD drawings. The inputs are taken directly from here and area used to create flat forms that are extremely complex. The laser cutting process has a 3-axis control which outlines each of the parts depending on the information it has got. Lasers are best used for materials such carbon steel as well as stainless steel.
The process is pretty simple and the laser beams are what cut everything in its path. For materials that can be treated with heat, the edges automatically harden around the edges that have been cut. This is especially important if the hardened edges are essential from the functional point of view. But in case threading is also needed, then the hardening process is not really a good thing to happen.
What you should know that if any hole is cut with a laser, the entry point is larger than the exit point in terms of the diameter. The result is always a tapered hole. When it comes to slot corners you are looking at sizes like .75 mm. In the case of laser beam cutting basic concepts of construction such as minimum wall thicknesses as well as hole sizes are not applicable here. Hole sizes here are based on stock thicknesses and can go down to as low as 20% of the thickness desired.
The resultant burrs are always smaller when you compare it to the processes of blanking as well as shearing. In fact with the use of 3D lasers the burrs can be completely eliminated removing the need for any additional deburring applications.
What laser cutting essentially does it help you retain accuracy in your work. This allows work to go on smoothly and the end result faultless. It gives customer satisfaction and also improves the efficiency of your agency. Working with laser cutting is ideal for all those in the construction as well as its associated fields. Its creates a win win situation for all.
