While CNC machines are precise in manufacturing prototypes, they cannot manufacture products with sophisticated designs and shapes. So, here comes the CNC laser cutting machine, which has the ultimate precision power to cut, mark and design intricate shapes and tiny holes. In this article, you’ll learn what CNC metal manufacturing is and how it works. So, without any ado, let’s explore the CNC laser cutting services.

What is CNC Laser Cutting?

CNC laser cutting is the most effective method to manufacture aesthetically appealing intricate designs and shapes. However, like every CNC machine, CNC cutting depends heavily on computer numerical control and commands, often known as G-code.

Stamping machining is incredibly fast and results in less CNC material waste giving you the optimum efficiency. Laser cutting involves a complex process of using a laser beam to melt, vaporize and carve the material to manufacture the shapes, holes, and designs.

During the laser cutting process, the tip of the nozzle doesn’t touch the object, and it is a thermal-based process.

How Does CNC Laser Cutting Work?

CNC laser cutting uses compressed gas to reduce the high temperature of the focusing lens. The focusing lens consists of a laser head. And the lens focuses with the help of a nozzle. Once the lens and head concentrate on the material, they melt the fabric and cut the piece into the desired shape, design, and form. But how does even a CNC laser cut work?

Try to look at it another way. Once you focus the laser beam, which has high power at a single point on a metal surface, the heat density becomes so high that you can easily cut, mold, and engrave the shapes, marks, and holes according to the specifications. There are three different types of lasers a CNC cutting uses.

CO2 lasers are perfect for engravings and industrial use. If the CNC laser is of low power, then you can use it for engraving. And the laser has a high amount of power used for industrial applications such as cutting and welding.

YAG is fantastic to use for metal marking and etching.

Fiber lasers are cost-effective and versatile to use in cutting many different materials. In addition, these lasers have solid-state construction and tremendous power output.
precision sheet metal machining uses an electrically exciting laser. So, you can use it for a wide variety of applications.

Types of CNC Laser Cutting Machines

Like CNC machine types, metal manufacturing machines also differ based on the active laser medium and its components. Most commonly, there are three types of CNC laser cutters such as:

  1. CNC crystal laser cutter
  2. CNC CO2 laser cutter
  3. CNC fiber cutter

1. CNC Crystal Laser Cutter

If you have thick metal, a CNC crystal laser cutter is the best choice. Crystal laser cutter uses the beam made from neodymium-doped yttrium ortho-vanadate (Nd:YVO) and neodymium-doped yttrium aluminum garnet (Nd:YAG). However, you can use many materials such as glass, wood, plastics, and metals.

2. CNC CO2 Laser Cutter

If you want a highly refined product, engraving, and output, then a CNC CO2 laser cutter can be the best bet. It is a gas type that uses carbon dioxide as an active laser medium. You can use the CNC CO2 laser cutter where the thickness of the material is less than 10 mm. As a result, you can get fine-tuned, intricate, and highly detailed designs.

3. CNC Fiber Laser Cutter

CNC fiber laser cutter is a recently invented laser cutting technology. It uses a bank of diodes to form a beam. A CNC fiber laser cutter focuses the beam through a fiber-optic cable. If you want to enjoy a cleaner, faster, and highly precise cutting operation, then CNC fiber laser cutting is the best decision. It is recommended to use fiber laser cutting where the material thickness is less than 5mm.

You can use the CNC fiber laser cutter to machine a wide variety of materials but show great care while machining the silver. However, it retains the heat and can accumulate, making the process harder for precise cutting. So, when machining the silver, use a bracket as a heat sink to transfer the heat away from the silver material.

Why Should You Choose CNC Laser Cutting?

Technology always evolves, and the process is fast when we talk about the machine tool manufacturing industry. Stamping machining has many advantages over conventional CNC machining. Some of the benefits of selecting cnc laser cutting services are given below:

  • CNC laser is more accurate, precise, and highly sophisticated. You can design the holes and designs even 2mm small.
  • Steel laser cutting saves you big bucks by removing any need for post-processing. The cuts, marks, and engravings are highly precise and subtle.
  • Unlike conventional CNC machining, you don’t need any extra tools while machining any material using CNC cutting. Likewise, you don’t need any additional devices such as CNC routers and CNC milling machines.
  • Using the CNC laser cutting machine gives you faster processing and production.
  • Precision sheet metal machining gives you even greater accuracy than Flame and Plasma cutting.

Precision laser cutting is a reliable, faster, and highly cost-effective method to manufacture subtle designs and new products in bulk. In addition, laser cutting is a non-contact method, so it wreaks minimum wear to the CNC machine tools.
