Product Description

Laser Cutting Fittings

Core Applications

Industrial Equipment: Processing bathroom fittings (such as sink brackets, shower rods), furniture fittings (such as chair frames, clothes drying rods), automobile exhaust pipes and hydraulic pipes.

Precision Manufacturing: Medical equipment needles, sensor housings, electronic device heat dissipation pipes and other scenes with high precision requirements.

Architecture and Decoration: Customized cutting of stainless steel guardrails, curtain wall support pipes, and special-shaped decorative pipes

Pipe Cutting Forms

Two-Dimensional Cutting: Round/square pipe cutting, plane opening (such as heat dissipation holes, connection holes)

Three-Dimensional Cutting: Multi-angle bevel cutting, intersecting line cutting (for pipe welding interfaces)

Special Processing: Shrinking/expansion, bending, surface engraving or marking].

Processing Range and Materials

Applicable Materials
- Metal Pipes: stainless steel (304/316), carbon steel, aluminum alloy (6061/6063), copper pipes
- Composite Pipes: galvanized steel pipes, coated anti-corrosion pipes (laser parameters need to be adjusted to avoid ablation)

Size Range
- Round Pipes: diameter 5-300mm, wall thickness 0.25-5mm
- Special-Shaped Pipes: square pipes (10×10mm to 200×200mm), oval pipes, D-shaped pipes, etc.

Processing Precautions

● Material Pretreatment: Before cutting, the oil and oxide layer on the surface of the pipe need to be cleaned to prevent laser reflection interference and burrs on the cutting surface

● Fixture Adaptation: Thin-walled pipes (such as wall thickness <1mm) need to use flexible clamps to avoid clamping deformation.

● Parameter Optimization: Adjust the laser power (1-4kW is commonly used for carbon steel), cutting speed (0.5-20m/min) and auxiliary gas (nitrogen for oxidation prevention, oxygen for combustion of carbon steel) according to the material.

● Safety Protection: Equipped with a smoke exhaust system to handle cutting dust, operators need to wear goggles to prevent laser scattering

Quality Assurance and Tolerance Standards

Dimensional Accuracy	Surface Quality	Inspection Process
Cutting Length Tolerance: ±0.1mm (conventional parts), ±0.05mm (high-precision parts)	The cutting surface is free of burrs and slag, and the roughness Ra≤12.5μm (can be polished to Ra≤5μm later).	Spot check key dimensions (such as hole diameter, wall thickness) and record batch numbers to support quality problem traceability].
