High-Precision Stainless Steel Guide Rod CNC Turning - Custom Hardware Machining Services
Product Overview :
Our high-precision CNC turning services specialize in manufacturing custom stainless steel guide rods and non-standard hardware components with tight tolerances and superior surface finishes. Ideal for industrial automation, linear motion systems, and precision machinery, our CNC-machined guide rods ensure durability, corrosion resistance, and reliable performance in demanding applications.
Key Features :
✔ Material Expertise: Machined from high-grade stainless steel (304, 316, 17-4PH, etc.) for corrosion resistance and strength.
✔ Precision Turning: Tight tolerances (up to ±0.005mm) and fine surface finishes (Ra 0.4μm or better).
✔ Custom Solutions: Tailored to non-standard specifications—diameters, lengths, threads, grooves, and special geometries.
✔ Secondary Processing: Optional grinding, polishing, heat treatment, or coating for enhanced performance.
✔ Fast Prototyping & Mass Production: Supports both small-batch samples and large-scale orders.
