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.
Laser cutter can cut a wide range of materials, incl. stainless steel, carbon steel, alloy steel, silicon steel, aluminum, aluminum alloy, galvanized sheet, aluminum-zinc plate, pickled sheet, titanium, and other metal sheets.
They can be applied in most metalworking industries, such as sheet metal working, kitchenware, aerospace, electrical cabinet, household kitchenware, automotive parts, construction and agricultural machinery, and more.
When selecting a laser cutter, we believe users should focus on 10 factors below:
* Laser power * Cutting speed * Cutting accuracy * Type of laser generator
* Degree of automation and software * Ownership costs * Material compatibility
* Technical support and service * Installation space and requirements * Environmental and safety factors
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
Optics & Nozzles: Clean protective lenses regularly with optical cloth; replace if scratched. Inspect nozzles for debris or damage; clean with a brass brush or replace if deformed. Always wear gloves when handling lenses.
Focus & Alignment: Even with autofocus, manually verify focal point and alignment periodically to match material thickness.
Cleanliness: Empty slag trays after each shift. Wipe surfaces, vacuum metal dust, and clean rails/guideways to prevent dust buildup.
Gas & Air Systems: Ensure adequate assist gas supply. Replace air filters, drain moisture from tanks, and check dryers and pipelines for damage or blockages.
Safety Devices: Regularly test emergency stops, door interlocks, light curtains, and enclosures.
Parameter Backup: Back up machine settings and cutting parameters weekly to prevent data loss.
Lubrication: Check oil levels, add standard lubricant as needed, inspect oil circuits, and clean dust from moving parts.
Consumables: Replace nozzles, ceramic rings, and protective lenses in time based on usage to avoid unplanned downtime.
Coolant: Use pure, distilled, or deionized water; add antifreeze below 0°C. Replace coolant periodically.
Electrical System: Only certified electricians should inspect breakers, connections, and wiring.
Maintenance Log: Record materials, settings, and issues to track performance and spot problems early.

Yes. Our machines are usually equipped with advanced CNC systems that use capacitance centering to measure tube’s actual size and automatically calibrate to align the tube profile with its model. It also features real-time compensation for tube deviation, reducing requirements for tube clamping and improving the tube piercing accuracy.
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.
Operating press brake is not only a challenge but also a chance to grow up for beginners. By following tips below, they can navigate the complexities of CNC press brake operation with greater ease and efficiency.
* Familiar with the press brake and operating manual
* Receive professional training
* Set and adjust parameters correctly
* Gradually master programming skills
* Focus on material selection
* Adhere to safety operating procedures
* Monitor and adjust machine status
* Perform regular maintenance
* Accumulate practical experience
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.
Main welding types include butt welding, overlay welding, stitch welding, stud welding, T-joint welding, internal & external corner welding and seal welding. It has advantages such as deep welding depth, narrow width, small heat-affected zone, minimal deformation and fast welding speed.
Laser welding uses laser beam as heat source. The main objects of welding are thin-walled materials and precision parts, such as stainless steel, carbon steel, mold steel, copper, aluminum, gold and silver. It can also repair defects such as wear, pore, sand hole, crack, scratch, deformation, and reduced hardness in workpieces.

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.
Fiber laser cleaning machines are suitable for various applications, including but not limited to:
Metal rust removal: Eliminate rust from surfaces like steel, iron, and aluminum.
Surface cleaning: Remove grease, dust, oxidation layers, etc.
Coating removal: Strip paint, plating, or other coatings from materials.
Pre-welding or pre-cutting surface preparation: Clean surfaces to improve welding or cutting quality.
Cultural artifact restoration: Remove dirt from artifacts while preserving their surfaces.
With precise adjustments to power and frequency, fiber laser cleaning can effectively remove impurities while protecting the base material. It is especially suitable for metal surfaces and typically does not cause mechanical damage or create a heat-affected zone (HAZ).
Eco-friendly: No chemical cleaners or pollutant emissions.
Efficient: Fast cleaning with excellent results.
Non-contact: No direct contact with the workpiece, preventing damage.
Precise: Ideal for complex shapes and hard-to-reach areas.
Low cost: Low maintenance costs over time.
The power of a fiber laser cleaning machine determines its cleaning capability:
Low power (50W-100W): Suitable for light dirt or fine surface cleaning.
Medium power (200W-500W): Ideal for moderate rust or coating removal.
High power (1000W and above): Designed for thicker coatings or heavy rust removal.
Power selection should be based on the specific application and material characteristics.
Pulsed Laser Cleaning Machines:
Ideal for cleaning sensitive or high-value materials.
Common in industries like aerospace, electronics, and cultural artifact restoration.
Continuous Wave Laser Cleaning Machines:
More suited for heavy-duty industrial cleaning tasks.
Frequently used in manufacturing, shipbuilding, and large-scale metal processing.
Although fiber laser cleaning machines are primarily used for metal surfaces, they can also treat some non-metallic materials like rubber or stone by adjusting laser parameters. However, caution is required when dealing with flammable or explosive materials.
The core component of a fiber laser cleaning machine is the fiber laser, which typically has a lifespan of over 100,000 hours, ensuring long-term use with proper maintenance.
Maintenance for fiber laser cleaning machines is relatively straightforward and includes:
Regular cleaning of optical lenses.
Inspecting and maintaining the cooling system.
Keeping the working environment for the fiber laser clean and stable.
11. Does laser cleaning pose any risks to the environment or operators?
Fiber laser cleaning is an environmentally friendly technology with no chemical pollution. However, operators must wear protective goggles to avoid direct laser exposure to the eyes and ensure proper ventilation to minimize inhalation of particles or smoke.
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.
The materials used for laser cladding are mainly thermal spraying and thermal welding materials, such as self-fusing alloy materials, carbide dispersion, or composite ceramic materials, which possess excellent wear and corrosion resistance. They are usually used in powder form, and during cladding, flames spray-welding may be employed to achieve a smooth surface with good adhesion to the substrate.
