What is laser cutter and how does it work?
A laser cutter uses laser as heat source and can be classified as sheet cutting and tube cutting. This includes sheet laser cutter, tube laser cutter and sheet & tube combo, making it one of the most advanced metal processing equipment available today.
The laser cutter utilizes the high-density laser beam to convert laser energy into thermal energy, causing localized heating, melting or even vaporization of materials. The melted or vaporized material is then blown away by using gas flow or other methods to achieve cutting.
The power of a fiber laser directly impacts its cutting capabilities. Fiber lasers with different power levels are suitable for various material thicknesses and types. The following article provides an overview of the cutting capabilities for the main power ranges: Cutting Capacity and Speed of 1.5kW-80kW Fiber Lasers
A press brake is a device that can bend thin sheet metals. It generates pressure through a hydraulic system, which is transmitted by upper and lower molds to achieve the desired bending shape. Depending on its drive mode, level of automation and structure, press brakes can be classified into manual, hydraulic and CNC press brakes.
Panel bender is a highly automated bending machine, representing the latest advancement in sheet metal bending. It can bend into various complex shapes such as right angle, arc, up and down, without the need for manual holding of workpiece or bending mold. One-time positioning is enough for multi-side bending. Its bending speed is about 3 times faster than traditional press brakes. Due to the fewest human intervention, the consistency among workpieces is much higher, and it is gradually replacing the tradition.
For the panel bender, workers only need to place workpieces on its worktable, then, the workpiece will be positioned by suction cup or press-down arm and bent automatically. A set of universal bending mold is enough, without frequent change or customization.
A laser welding machine is a device used for welding materials. It has a high power density and fast energy release, making its welding efficiency superior to other traditional welding patterns. Whether welding the same type or different materials, it is unnecessary to carry out secondary treatment. Its emergence has led to a large leap in welding technology.
Laser welding utilizes high-energy laser beam to locally heat small areas of materials. The energy from laser radiation quickly diffuses into the material through thermal conduction, melting the material to form a specific molten pool for welding purpose.
Currently, SENFENG can offer more than 10 kinds of different welding machines for customers worldwide. According to degree of automation, we have handheld and robot-assisted machines. Based on cooling mode, there are air-cooled and water-cooled types. With regard to heat source, laser welding and electric-arc welding are available now. Customers may make decision or apply for customization as needed.
A fiber laser cleaning machine is a device that uses a high-energy laser beam to remove dirt, rust, coatings, or other impurities from the surface of materials. It is non-contact, environmentally friendly, and highly efficient, making it widely used in industrial cleaning applications.
Fiber laser cleaning works by directing a high-energy laser beam at the material’s surface. The laser rapidly heats and evaporates or breaks down rust, coatings, or contaminants, effectively removing them while causing minimal impact on the base material.
Laser cladding is an important method for surface modification of materials. It uses high-energy laser beam to irradiate the metal surface for rapidly melting, expanding and solidifying. The cooling rate typically reaches 102 to 106℃/s, then, a layer of material with special physical, chemical or mechanical properties will take its shape on the substrate surface, thus creating a new composite material. This process can compensate for the lack of high performance in the base material and significantly improve substrate surface properties in terms of wear, corrosion, high temperature and oxidation resistance.
Compared to commonly used methods such as overlay welding, thermal spraying and plasma spraying, laser cladding has the following advantages:
* The heat-affected zone is small, resulting in minimal deformation of workpiece and a high yield of cladding.
* The layer has fine crystal grains and dense structure, leading to relatively high hardness and better wear and corrosion resistance.
* Due to short duration of laser action, the dilution rate of cladding layer is low, which causes a smaller amount of material melted (typically 5%-8%). Therefore, it is possible to achieve the desired composition and properties even with a thin cladding layer, and to produce new structural features such as metastable phase, ultra-dispersed phase and amorphous phase.
* It is easy to automate the laser cladding, and the quality of cladding layer is always stable.
It is an equipment that uses digital information control to carry out milling. It has characteristics of high precision, high efficiency and high automation, and develops into an indispensable equipment in modern manufacturing industry.
Compared to other common machine tools, it is featured by:
* High processing accuracy with stable quality.
* Capable of multi-coordinate linkage, allowing for the cutting of complex-shaped parts.
* When changing spare parts, only CNC program needs to be modified, saving make-ready time for production.
* The machine tool itself has high precision and rigidity, resulting in high productivity (typically 3-5 times that of others).
* High degree of automation, which can reduce labor intensity.
* Higher quality requirements for operators and even higher technical requirements for maintenance staff.
