We manufacture precision laser-cut machinery parts from SS316 austenitic stainless steel plate, serving equipment builders, machine tool OEMs, and industrial automation companies worldwide. SS316 (UNS S31600) is the benchmark material for machinery components that must survive corrosive coolants, frequent washdown cycles, coastal atmospheres, or food-grade sanitizing chemicals—while still delivering the ductility and weldability needed for complex fabricated assemblies.
Our production focus is on mechanical functionality: bearing housings, drive brackets, guard frames, pump flanges, and conveyor rails that require precise hole patterns, clean slot edges, and flat mounting surfaces. Every part is processed with parameter sets calibrated for 316's thermal properties, ensuring cut edges are free of oxide inclusions that would compromise fatigue life or interfere with bearing press-fits.

Laser Cutting Capabilities for Machinery Parts
Precision Hole Arrays: CNC fiber lasers produce bolt circles, dowel holes, and clearance slots with positional accuracy suitable for direct bearing and gearbox mounting—often eliminating the need for secondary jig boring.
Narrow Kerf, Minimal HAZ: The concentrated beam produces a kerf width of 0.2–0.4 mm with a heat-affected zone under 0.5 mm, preserving 316's corrosion resistance at the cut edge and preventing sensitization that could lead to stress corrosion in service.
Tab-and-Slot Joints: Interlocking features cut directly into plate edges enable self-fixturing weldments and boltless assembly of machinery frames, reducing shop-floor fit-up time.
Small Feature Resolution: Holes down to 1.0× material thickness; slots and lightening holes for robotic arm brackets and rotary table plates produced without drill tooling.
Thick-Plate Penetration: High-power beams cut 316 plate up to 40 mm in a single pass, producing heavy-duty machine base plates and press bolster sections with clean, square edges.

Marine & Offshore Equipment: Winch base plates, hydraulic manifold mounting pads, and deck machinery guards resisting salt spray
FAQ
Q: For machinery parts, when should I choose SS316 over SS304?
A: Choose SS316 when your machinery operates in environments with chlorides—such as coastal factories, swimming pool equipment, or food processing with salt or acidic cleaners. The 2–3% molybdenum in 316 provides critical pitting resistance that 304 lacks. For indoor machinery in dry, benign atmospheres, 304 is usually sufficient and more economical.
Q: Can laser-cut SS316 holes achieve press-fit tolerances for bearings and dowels?
A: For standard clearance holes and bolt patterns, yes—our laser cutting achieves H11–H12 tolerances directly. For precision press-fits (H7–H8), we recommend laser cutting slightly undersized and performing a final ream or CNC bore. We can deliver parts at either stage: as-cut for your in-house machining, or finish-machined to your specified fit.
Q: Does the laser cutting process affect the fatigue life of SS316 machinery brackets?
A: When cut with nitrogen assist and optimized parameters, the heat-affected zone in 316 is minimal and does not significantly reduce fatigue life. However, for brackets subject to high-cycle vibration (e.g., engine mounts or pump feet), we recommend post-cut edge radiusing or surface polishing to eliminate microscopic notch effects at the kerf edge.
Q: Why is SS316 preferred for machinery in magnetic-sensitive environments?
A: Annealed SS316 is essentially non-magnetic (relative permeability <1.05). This makes it ideal for machinery near linear encoders, magnetic sensors, MRI-adjacent equipment, and semiconductor handling systems where ferrous contamination or magnetic interference would cause operational failure. Cold working can induce minor magnetism, which we can mitigate with solution annealing if required.
