![]() CNC lasers employ compressed gas (also flowing through the nozzle that ejects the laser beam) to cool the focusing lens and expel the vaporized metal out of the workpiece. Through the nozzle, this head and lens assembly focuses a laser beam - a column of very high-intensity light ㅡ on the workpiece, melting and cutting the workpiece to form the desired shape. A CNC laser cutter features a laser head containing a laser focusing lens and a nozzle. ![]() However, CNC laser cutters differ slightly from conventional CNC machines in their design and method of cutting operation.ĬNC laser cutting is a non-contact, thermal-based process. Like every other type of CNC machine, a CNC laser cutter relies on computer numerical control and computer instructions ( G-code) to perform its sequence of cutting operations. ![]() What is a CNC Laser Cutter, and How Does it Work?
