A laser cutting engraving machine uses a precision laser to cut through virtually any type of material. This machine can be used to create items of a custom size and shape or to engrave personal messages or images onto other materials. This type of machinery may be used to set up or expand an existing custom engraving business. It may also be used by large manufacturing companies to create specialized machinery parts and templates.
Each laser cutting engraving machine consists of an engraving area, a roller bearing assembly, laser tubes, and computer and internet connectors. The size of the engraving area often determines the size of the projects undertaken, with more expensive models featuring larger work spaces and pass through assemblies in which materials may be run at length through the machine. The roller bearing assembly works on a guiding bar which allows the machinery to move back and forth while creating the specified design. The laser tubes perform the actual cutting and engraving and are sized by wattage. The computer and internet connections on the device enable the user to send designs to the machine and update the software as new programs become available.
There are a wide variety of special features available on a laser cutting engraving machine, which can greatly increase the price of the model. Most models will feature a red dot guidance system, which shows by use of a lit pointer where on the intended material the engraving or cutting will occur. 3D engraving may be added for users who need to engrave an image with varying heights and levels across the surface. Some models feature a control screen on the machinery itself, allowing settings to be changed and information input without the use of an interfacing computer. Consumers should speak with a manufacturer and distributor about the specific features they will need to perform the work required by their business, whether creating signs, machinery parts, or custom stamps.

The speed and power of the laser cutting engraving machine are, in part, determined by the wattage of the laser tubes. Higher numbered tubes can cut through thicker materials and perform engraving jobs faster. Basic machines are typically sold with a 40 watt laser tube. Higher powered models are available with 60 watt, 80 watt, and 100 watt tubes for better performance. Industrial sized machines are occasionally equipped with two lasers, each operating at 75 watts, for a combined cutting power of 150 watts.
The internal motor is the second factor that determines the speed with which a laser cutting engraving machine can work. The motor must start and stop multiple times during one engraving or cutting job to complete any specified design. It must increase its speed and decelerate instantly to achieve high quality results. These movements place a great deal of strain on the internal motor, requiring a sleek and efficient design which can withstand the stress and intensity of performing this type of work. Stepper and servo motors are two of the more commonly used types of motors to power these machines.
