304 Stainless Steel Tube Precision Laser Cutting Punching Slotting

Product Description

Precision Laser Cutting, Drilling, and Slotting Service for 304 Stainless Steel Tubes is a specialized fabrication process that transforms standard round, square, or rectangular tubing into highly functional and complex components. Utilizing advanced CNC fiber laser systems with rotary axes, this service delivers exceptional accuracy in creating clean holes, intricate slots, and custom-shaped cutouts directly on the tube surface. The process produces minimal heat-affected zones and burr-free edges, making it ideal for applications requiring precise fluid dynamics, structural integrity, ventilation, or aesthetic detailing. The corrosion-resistant properties of 304 stainless steel are fully preserved, ensuring durability and longevity in the finished parts.

Product Processing

1. Design & Programming: Customer CAD files (DXF, DWG, STEP) are analyzed. Precision toolpaths are programmed for the laser system, optimizing for cut quality and speed. Nesting software is used for batch production.

2. Material Preparation & Fixturing: Certified 304 stainless steel tubing is cut to manageable lengths, cleaned, and securely mounted in the laser machine's CNC rotary chuck. Proper fixturing is critical to prevent vibration and ensure accuracy during cutting.

3. CNC Laser Processing (Core Process): A high-power fiber laser beam, directed by the CNC system, performs all operations in a single setup:

   • Cutting to Length: Precise trimming of tube ends.

   • Hole Drilling: Creating round or shaped holes at specified locations and angles around the tube's circumference.

   • Slot Cutting: Machining straight, helical, or custom-profile slots with precise width and length.

   • Contour Cutting: Cutting complex 2D patterns or profiles along the tube.

4. Post-Processing Deburring: Although laser cutting leaves minimal burrs, a secondary deburring process (mechanical, electrochemical, or thermal) is applied to ensure all edges are perfectly smooth and safe.

5. Cleaning & Inspection: Parts are cleaned to remove any oxidation or residue from cutting. Each component undergoes dimensional inspection using calipers, pin gauges, optical comparators, or CMMs to verify hole/slot placement and size.

6. Optional Finishing & Packaging: Additional surface finishing (e.g., electropolishing, passivation) can be applied. Parts are then carefully packaged to prevent damage during shipping.

Product Applications

• Fluid Handling & Filtration: Sparger tubes, filter housings, distribution manifolds, and slotted liners where holes/slots control flow or act as screens.

• Architectural & Design: Decorative railings, sunscreens, lighting fixtures, and furniture components with intricate perforated or slotted patterns.

• Mechanical & Structural: Adjustable sleeves, coupling guards, heat sink tubes, and frames with integrated mounting or adjustment slots.

• Food & Beverage Processing: Sanitary spray bars, aeration tubes, and mixing elements with precision slots for consistent fluid dispersion.

• Automotive & Aerospace: Lightweight structural tubes with vent holes, sensor mounting brackets, and exhaust components.

• Medical Equipment (Non-Implantable): Support frames, handles, and guards for devices requiring hygienic, cleanable surfaces.
