Laser Cutting

1、Process Introduction | What can laser cutting solve?

High precision contour: Fiber laser cutting seam of 0.1 mm, sharp angle R ≤ 0.05 mm, meeting the requirement of no machining assembly holes
Complex arbitrary graphics: Import DXF/DWG in one go, six axis linkage can cut 3D surfaces, slopes, and horn mouths
High speed thin plate: 1 kW power, 1 mm carbon steel speed, 18 m/min, 3 times faster than plasma
Small heat affected zone: Fiber laser HAZ ≤ 0.2 mm, stainless steel directly rolled after cutting, no micro cracks
Multi material compatibility: carbon steel, stainless steel, aluminum, copper, brass, titanium, composite materials, laminated board

4、Laser Cutting Case Studies | Cutting Cases

Case 1 | New Energy Battery Tray Bottom Plate

Material: 2.5 mm 3003-H14 aluminum

Graphic: 360 φ 8mm heat dissipation holes with irregular contours around the long weld seam position

Challenge: Relative position of holes ± 0.05 mm, heat affected zone<0.2 mm

Solution: 8 kW nitrogen cutting, nozzle 1.2 mm, AI focus real-time tracking

Result: Cutting speed of 15 m/min, hole roundness of 0.03 mm, direct deburring to enter the next riveting process

Case 2 | Construction Machinery 20mm Thick Plate Connection Seat

Material: Q355B hot-rolled plate 20mm

Graphic: Appearance 850 × 450 mm, 12 positioning holes with a diameter of 30 mm

Solution: 12 kW oxygen cutting, BeamShaper glossy process; Common edge cutting saves 18% of board material

Result: The cutting width is 0.35 mm, the slag hanging height is less than 0.1 mm, and there is no need for secondary polishing

Case 3 | 3D cutting of brass instrument horn mouth

Material: Cu-Zn30 brass 1.2 mm

Graphics: 3D horn mouth 120 ° cone, 360 ° continuous curve

Solution: Nitrogen 12 bar, 3D five axis head, following focus

Result: There is no oxidation on the edge, and the coating can be directly polished, saving 2 manual processes

5、 Gas and energy consumption

Fiber laser electro-optical conversion of 35%, energy consumption only one-third of CO₂ laser
Air cutting: 1-6 mm carbon steel, cost ↓ 40%>
Oxygen cutting: 7-25mm carbon steel, glossy effect
Nitrogen cutting: stainless steel/aluminum/copper, no oxidation residue
High pressure nitrogen 30 bar: Copper 12 mm non reflective, safe cutting

6、 Automation and traceability

Automatic nozzle replacement 5-25mm, nozzle replacement time<25 s
Automatic edge finding+six point calibration, accurate cutting can still be achieved even if the deviation of the board is ≤ 0.5 mm
AI algorithm for surplus material layout, material utilization rate increased by 8-12%
QR code marking: After cutting, directly laser mark the part number and furnace number, scan the code for traceability
MES docking: Real time uploading of cutting time, gas type, power, and speed data
