How It Works: The Laser Cutting Process

Laser cutting is used for many applications and throughout various industries. As long-time providers of top-quality laser cutting in Toronto, Metal-Tronics understands the process deeply, being experts in all sorts of custom fabrication and cutting services.

In today’s blog, we shed some light on the process of laser cutting. It is not an easy process, and being a technician that can successful execute it requires hard work and in-depth knowledge.


Here are 4 crucial elements in the laser cutting process:


1. The laser (a column of single-wavelength, high intensity light) has to pass through the bore of the nozzle and focus on spot on the cutting material that is to be cut. In addition to the laser, a compressed gas such as oxygen or nitrogen will also

2. Before hitting the nozzle, the laser goes through a focusing lens in the cutting head, which is a lens unique for its ability to focus high-intensity, high-heat lasers. The energy of this laser can be around 6 kilowatts, focused onto a single spot, creating enough heat that the cutting material melts or vaporizes.

3. Laser cutters are powered by software wherein the calculations for a particular design are inputted into the software, and computer then moves the laser accordingly to the correct spot.

4. Height matters – part of the intricacy in laser cutting comes from the calculations needed for the capacitive height control system, which can raise or lower the focal point of the laser.


Thanks to this powerful process, laser cutters can work with the toughest materials out there such as diamonds.
