china 12kw fiber laser cutting machine supplie

A 12kW fiber laser cutting machine is significantly more expensive than a 6kW model, typically 30-40% higher in price. However, the higher power allows for much faster cutting speeds, especially on thicker materials.

Speed and Productivity

A 12kW laser can cut through 1.125 inch (28.5mm) thick steel plates at up to 150 m/min (492 ft/min), which is up to 3 times faster than a 6kW laser for thick materials.
Processing time can be reduced by up to 50% compared to lower power lasers due to the higher cutting speeds.
The high acceleration of nearly 2.5G enabled by the rigid machine design further increases productivity.

Cost Justification

The higher upfront cost of a 12kW laser may be justified for production environments with high volumes of thick plate cutting where the increased throughput can provide a quicker return on investment.

For lower production volumes or thinner materials, a 6kW laser may be more cost-effective as it can run continuously without the higher capital expense.

Other factors like material handling, secondary operations, and overall manufacturing process capabilities also need to be evaluated to fully utilize the higher output rates of a 12kW laser.

In summary, while a 12kW fiber laser costs significantly more upfront, the exceptional speed and productivity gains on thick materials can make it an economical choice for high-volume cutting of thick plates in a production environment designed to take advantage of the increased throughput

Maintaining a 12kW laser cutting machine is crucial to ensure its longevity, efficiency, and precision. 

Regular Maintenance Tips:

1. Daily Inspections:

   • Check Laser Optics: Inspect the condition of lenses and mirrors. Clean them if there are any signs of contamination or dirt using proper cleaning agents and tools.
   • Monitor Coolant Levels: Ensure the coolant system is functioning correctly and the coolant levels are sufficient. Replace the coolant periodically as recommended by the manufacturer.
   • Clean Cutting Bed: Remove any debris, slag, or leftover materials from the cutting bed to prevent damage to the workpiece and to maintain cutting accuracy.

2. Weekly Checks:

   • Lubricate Moving Parts: Apply lubrication to all moving components such as guide rails, gears, and bearings to reduce wear and tear.
   • Inspect Gas Supply: Check the gas lines and connections for leaks and ensure the gas cylinders are adequately filled. This includes checking the purity of the assist gases used in cutting.
   • Alignment Checks: Verify the alignment of the laser beam and adjust if necessary to maintain precision cutting.

3. Monthly Maintenance:

   • Inspect Electrical Connections: Check all electrical connections and wiring for any signs of wear or damage. Tighten any loose connections to prevent electrical faults.
   • Filter Replacement: Replace or clean air filters in the machine to ensure proper ventilation and cooling.
   • Software Updates: Check for any firmware or software updates from the manufacturer and apply them to ensure optimal performance and security.

4. Quarterly Maintenance:

   • Deep Cleaning: Perform a thorough cleaning of the machine, including all internal and external components.
   • Calibrate the Machine: Calibrate the laser machine to ensure it maintains high precision and accuracy in cutting operations.
   • Check Drive Systems: Inspect the drive systems, including belts and pulleys, for any signs of wear and replace them if necessary.

These manufacturers are well known for their high-power fiber laser cutting solutions, and their machines are designed for excellent cutting performance, especially when cutting thick materials such as steel plates. High-end models from brands such as BESCutter and Senfeng offer excellent quality, reliability, and after-sales support, and their higher prices are justified compared to more affordable options listed on FORSUN or Alibaba.

The maximum thickness of stainless steel that can be cut by a 12kW laser cutter typically ranges between 30mm to 40mm. However, this can vary depending on several factors, including:

1. Quality of the Laser Cutter: Higher-end laser cutters with advanced technology and better beam quality can achieve thicker cuts.
2. Type of Stainless Steel: Different grades of stainless steel have varying levels of cutability. For example, 304 stainless steel may have different cutting properties compared to 316 stainless steel.
3. Assist Gas: The type and quality of assist gas used (typically nitrogen or oxygen) can significantly impact the cutting thickness and quality.
4. Cutting Speed: Slower cutting speeds can allow for thicker materials to be cut, but this may also affect the overall efficiency and quality of the cut.
5. Focus and Nozzle Design: Proper focus settings and nozzle designs can optimize the cutting process for thicker materials.

While a 12kW laser costs 30-40% more upfront compared to a 6kW model, the higher productivity and capabilities can provide a quicker return on investment for production environments dealing with thick plate cutting. However, the entire manufacturing process needs to be optimized to fully utilize the increased output rates of a high-power 12kW laser cutting system.
