Both CNC routers and laser cutting machines perform precision subtractive processes that program the stock materials used to make parts. There are differences between CNC cutting and laser cutting. Each application provides the manufacturer with its unique features, advantages and advantages.

 

CNC Cutting


Designs programmed into the CNC machine signals the router to cut or carve material with precision— the computer controls the exact velocity and positioning—back and forth or side-to-side on axes to specification. Speed, efficiency, and ease of use coalesce to increase productivity and enhance product quality in fabrication processes.

CNC routers are a contact-based cutting process similar in concept to handheld routers, with the obvious advantage of having the versatility and flexibility found in automated CNC cutting. A CNC router is adept in cutting or engraving materials with speed and precision. Like laser cutters , it can cut materials such as plastic, foam, wood, composites, acrylic, and is ideal for cutting steel, aluminum, and other metal plates to specifications.

Laser Cutting


Like CNC routers, a CNC machine guides the laser cutter. The prime difference is in how the cutting is achieved. It is a non-contact, thermal-based process that employs a focused, high-powered laser beam that cuts custom shapes and designs from stock material. There is no custom-designed tooling required, either. Cutting relies on heat to perform precision cuts. Rather than carving, a high-energy beam burns through the material. The fabrication process is suitable for a number of materials such as metal, glass, plastic foam, gemstones, wood and paper or corrugation. One laser cutting machine can perform multiple processes.

 

Main Difference Between CNC Cutting and Laser Cutting


CNC cutting uses a CNC router, while laser cutting relies on a laser beam.

When CNC cutting, there should be contact between the material and the machine, but for laser cutting, you don't need it, and it can be done easily from a medium distance.

Since laser cutting uses heat energy, it consumes a lot of power. As a result, electricity bills will rise, but CNC cutting requires minimal power to run smoothly.

Laser cutting provides high precision, and professionals don't need to pay extra physical effort to make sure everything goes smoothly. In the case of CNC cutting, it must be continuously adjusted.

Large industries have a great demand for laser cutting. Unfortunately, CNC cutting is not popular in this category, but fortunately it is very famous in schools and small businesses.

For welding purposes, laser cutting technology is the only way to achieve successful results. Regrettably, CNC cutting is not a good choice for this important task.

In the case of laser cutting, the cut edge will always be perfectly sealed, but this is not the case for CNC cutting. Heat makes the laser machine a very efficient machine, and then CNC.

In terms of cost, laser cutting is more expensive than CNC cutting. Those who like excellent precision and are not threatened by price; laser cutting will be the right choice. Therefore, it is still the first choice of well-known industries in the world.
