Everything evolves with time, and CNC machining is no exception. Constantly, the manufacturing industry has changed over the years and went from conventional manual machining to Computer Numerical Control (CNC) machining. The rising consumer demands, the high demand rate, and sophisticated designs give birth to a new way to manufacture and machine the machining parts. The CNC machinists accepted the challenge and took even a step ahead of conventional CNC machining to CNC laser cutting.
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:
- CNC crystal laser cutter
- CNC CO2 laser cutter
- 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.
Three Things to Consider Before Selecting A CNC Laser Cutting Machine
Now you know what CNC laser cutting is and how it differs from conventional CNC machines. But do you know how to select a cnc laser cutting service for your CNC machining project? Understanding the benefits of using laser technology must compel you to try out the latest manufacturing technology to manufacture your next product.
Instead of using conventional cutting tools, steel laser cutting employs laser beams. Through the heat, they mark, engrave and cut the materials according to the specific designs and requirements. So, let’s know about the three things you should consider before selecting a CNC laser cutting near me.
1. What’s Your Business?
Choosing a metal laser cutting machine will ultimately impact the results. So, before making a final choice, try to understand your business. For example, are you owning a small-scale business or a large-scale business? Or do you want to create highly sophisticated and aesthetically appealing designs?
These questions will be the guiding signs for the right precision laser cutting machine. On top of all this, the accuracy, precision, and purpose of use will also guide you through the process. Different types of CNC laser cutting machines, such as single head and double head machines, have other powers and precision.
So, if you want a highly precise and accurate product, go for a high-power laser machine. However, if your CNC machining project demands a high-precision but lower power, go for the low-power CNC laser cutting machine. These all choices will impact the price of the metal laser cutting, so make sure you know the business and its caliber.
2. What’s Your Budget?
Budget is the main point whenever you want to select a CNC laser cutting machine. You can’t escape the boundaries of the budget. So, make sure you choose the sheet metal products which come under your expected price.
Many parameters decide the price of sheet metal products, such as cutting power and precision. The higher the power of a metal manufacturing machine, the higher the price. More importantly, you’ve to face more expenses in case of any discrepancy and malfunctioning of the metal laser cutting machine.
So, while choosing any CNC laser machine, keep these points in mind to control the excessive expenditure under a threshold.
3. Quality of CNC Laser Cutting Machines
Laser technology is expanding exponentially, and manufacturers prefer laser cutting near me over conventional CNC machining. The demand is astonishingly rising, and the danger of confronting duplicate and lower-quality custom machining machines is also increasing. Some manufacturing companies would even tout the most powerful CNC laser cutting machine at the lowest price possible.
However, getting premium quality at the lowest price is not a sane option. So, whenever you want to choose a precision laser cutting machine go for the highest or at least suitable price possible. In this way, you can ensure the high-quality manufacturing of machining parts.
The tool manufacturing industry has come too far from manual manufacturing to CNC laser cutting technology. Even conventional CNC machining, despite being Computer Numerical Control (CNC), is not as fast, accurate, and precise as metal manufacturing machines.
There can be flaws in intricate designs made by CNC machines; however, engravings, marks, holes, and sophisticated designs made from precision laser cutting machines are precise, perfect, and highly accurate.
There are different types of precision CNC machining, such as single head and double head, and you should always choose which best fulfills your requirements. More importantly, there are many benefits of a CNC laser cutting machine, one of which is fast processing and production. So, next time you want to machine any material, give CNC laser cutting machine a try.
