Advantage of Laser Cutting
CNC grooving, which involves the use of Computer Numerical Control (CNC) machines to create grooves or channels in a workpiece, offers several advantages over manual or traditional grooving methods.
Precision and Accuracy
The CNC machine’s ability to follow programmed tool paths ensures consistent groove dimensions across multiple parts.
Improved Surface Finish
CNC grooving can produce high-quality, uniform surface finishes within the grooves, minimizing the need for additional finishing steps.
Increased Productivity
This integration allows for faster production times and reduced labor costs compared to manual or semi-automated grooving methods.
Versatility
The flexibility of CNC grooving enables efficient manufacturing of small-to-medium production volumes with design changes.
Consistent Quality
The automated nature of CNC grooving ensures consistent groove quality from part to part, reducing the risk of defects and improving overall product reliability.
Enhanced Design Flexibility
CNC grooving allows for the incorporation of complex groove geometries and patterns that would be challenging or impossible to achieve using traditional manual methods.
Laser Cutting Technology
Laser cutting is a advanced manufacturing technology that utilizes highly focused, high-energy laser beams to precisely cut, shape, and etch a wide range of materials. The technology behind laser cutting machining involves several key components and principles:
Laser Source
The laser source is the heart of the laser cutting system, which generates the intense, coherent light beam.
Common laser types used for cutting include CO2 lasers, fiber lasers, and solid-state lasers, each with their own unique characteristics and applications.
Beam Delivery System
The laser beam is guided and focused onto the workpiece using a series of mirrors, lenses, and other optical components.
This beam delivery system ensures the laser beam is directed to the desired location with high accuracy and precision.
Computer Numerical Control (CNC)
- Laser cutting systems are typically integrated with CNC technology, which allows for precise control of the laser beam’s movement and cutting parameters.
- The CNC system enables complex, computer-programmed cutting patterns and contours to be executed with high repeatability.
Cutting Head and Nozzle
The cutting head houses the final focusing lens and a coaxial nozzle that delivers assist gas (such as oxygen or nitrogen) to the cutting zone.
The assist gas helps to remove the molten material and protect the lens from contamination, improving the cutting quality and efficiency.
Material Handling
Automated material handling systems, such as conveyor belts or material feeders, are often integrated with laser cutting machines to streamline the production process and improve throughput.
Cutting Mechanics
Laser cutting relies on the intense heat generated by the laser beam to melt or vaporize the material being cut.
The cut quality and accuracy are influenced by factors such as laser power, cutting speed, assist gas flow, and material properties.
Safety and Control Systems
- Laser cutting machines incorporate various safety features, such as interlocked guards, emergency stops, and ventilation systems, to protect operators and the surrounding environment.
- Sophisticated control systems monitor and adjust the cutting parameters in real-time to maintain optimal performance and quality
Type of Laser Cutting Machine
There are several types of laser cutting machines used in manufacturing, each with its own unique features and applications. The main types of laser cutting machines include
CO2 Laser Cutting Machines
- CO2 lasers are the most commonly used laser type for cutting applications.
- They produce a high-energy laser beam in the infrared spectrum, making them well-suited for cutting a wide range of materials, including metals, plastics, and wood.
- CO2 laser cutting machines are known for their versatility, efficiency, and cost-effectiveness.
Fiber Laser Cutting Machines
- Fiber lasers use a solid-state lasing medium, typically a doped optical fiber, to generate the laser beam.
- Fiber laser cutting machines offer high beam quality, increased energy efficiency, and lower operating costs compared to CO2 lasers.
- They are particularly well-suited for cutting thin to medium-thick metal sheets, such as stainless steel, aluminum, and mild steel.
Solid-State Laser Cutting Machines
- Solid-state laser cutting machines use a solid-state lasing medium, such as a crystal or glass, to generate the laser beam.
- Examples include Nd:YAG (Neodymium-doped Yttrium Aluminum Garnet) and Nd:YVO4 (Neodymium-doped Yttrium Orthovanadate) lasers.
- Solid-state laser cutting machines are often used for high-precision applications, such as cutting thin materials or intricate parts.
Ultrafast Laser Cutting Machines
- Ultrafast laser cutting machines use femtosecond (10^-15 seconds) or picosecond (10^-12 seconds) laser pulses to achieve extremely precise and clean cuts.
- These lasers are particularly useful for cutting delicate or sensitive materials, as they minimize the heat-affected zone and thermal distortion.
- Ultrafast laser cutting is often employed in the manufacturing of microelectronics, medical devices, and high-precision components
Hybrid Laser Cutting Machines
- Hybrid laser cutting machines combine different laser types, such as CO2 and fiber lasers, in a single system.
- This allows for the versatility to handle a wider range of materials and thicknesses, optimizing the cutting process for each application.
- Hybrid systems can provide increased flexibility and productivity compared to single-laser machines.
CuttingTechnology Laser Cutting
Vaporization cutting
In the process of laser gasification cutting, the surface temperature of the material rises to the boiling point temperature so fast that it is enough to avoid melting caused by heat conduction, so part of the material vaporizes into steam and disappears, and part of the material is blown away as an ejection from the bottom of the slit by the auxiliary gas flow.In this case, very high laser power is required.
Melting and cutting
In laser melting cutting, the workpiece is partially melted and the molten material is sprayed out by means of air flow.Because the transfer of material only occurs in its liquid state, this process is called laser melting cutting.
Oxidation melting cutting (laser flame cutting)
Melting cutting generally uses an inert gas. If oxygen or other active gases are replaced, the material is ignited under the irradiation of a laser beam, and a fierce chemical reaction with oxygen produces another heat source to further heat the material. It is called oxidative melting cutting.
Control fracture cutting
For brittle materials that are easily damaged by heat, high-speed and controllable cutting is carried out by laser beam heating, which is called controlled fracture cutting.

Metal laser cutting machines are widely used, covering many industries, and are one of the necessary equipment for many enterprises. Among them, there are advertising sign production (these are mainly stainless steel LOGO and logo cutting), sheet metal processing (sheet metal processing basically includes all metal materials, these are generally mainly bending, polishing, etc., cutting is one of the most important processes), chassis cabinet production (this aspect is generally useful for carbon steel or stainless steel, but also mainly for bending and cutting two cutting processes), spring sheet (which belongs to the process of finishing), subway parts, and elevators. The production of housings, mechanical equipment housings, and kitchen utensils (mostly stainless steel). Among them, the laser cutting machine setting that surpasses the laser is also involved in the production of the seven gods and eight spaceships. These actually involve all aspects.It is widely used in sheet metal processing, advertising sign production, high and low voltage electrical cabinet production, mechanical parts, kitchenware, automobiles, machinery, metal crafts, saw blades, electrical parts, glasses industry, springs, circuit boards, electric kettles, medical microelectronics, hardware, knife measuring tools and other industries.
