An Introduction to Laser Cutters

Use of laser cutters is pretty common today. The past few years have witnessed several big manufacturing plants as well as small businesses replacing their traditional mechanical cutting appliances with advanced laser cutters. The main reason behind the huge popularity enjoyed by these cutting machines is their ability of offering precision. These machines use high power laser beams for cutting metal parts quickly and with great perfection. This article will inform you about the features and functions of laser cutters.

Let us begin the discussion by informing Best laser engraver you about the primary features of these cutting machines. As their name suggests, they are instruments that work using laser beams. The laser beam used by them typically possesses diameter of just 0.2 mm and come powered by 1,000-2,000 watts of electricity. Another prominent characteristic of the device is the series of mirrors embedded in it; these mirrors are required for directing the laser beam into the metal part it will be cutting.

Laser cutting is often used during the CNC/Turret process or the process during which holes are punched into a given material. The CNC/Turret process is meant for producing holes and similar internal features; laser cutters, on the other hand, are used for adding complex external features to metallic materials.

The person carrying out laser cutting needs to follow a CAD drawing. So, to complete these jobs perfectly one needs to have thorough knowledge of reading and comprehending computer-aided design. Metal parts, after being punched by a CNC/Turret machine, get profiled by laser cutters.

As mentioned above, these machines are designed primarily for cutting metal parts. To be more precise, they are best suited for cutting stainless steel and carbon steel. They are usually not used for cutting through copper and aluminum alloys as those metals lack the ability of reflecting light. Experts also don’t recommend using laser cutters for cutting those alloys as alloys that have copper or aluminum as one of their constituents also lack the ability of absorbing and conducting heat. For cutting through copper and aluminum alloys, you will need to use more powerful laser beams.

There are certain facts that you must be aware of before using laser cutters. One of the most important ones among them is that when these machines are used for creating holes in a metal body, the exit diameter is usually smaller than the entry diameter. This might sound weird to some, but experts say that this is one of the biggest benefits of using these cutting devices.
