2. Why Choose Fiwok for Stainless Steel Slender Parts?
- Anti-Deflection Technology: We utilize Synchronous Guide Bushing on our Swiss lathes, ensuring the cutting tool is always supported at the closest point to the workpiece, eliminating vibrations and bending.
- Specialized SS Tooling: Custom-ground micro-grain carbide tools designed for the toughness of stainless steel to achieve burr-free sharp tips and high-gloss finishes.
- Superior Concentricity: Our multi-axis setup allows for one-time clamping to finish both ends of the probe, ensuring perfect concentricity between the tip and the main body.

4. Quality Assurance & Expert Insights
Q: How does Fiwok manage the thermal expansion of stainless steel during micro-machining?
A: Stainless steel has a high coefficient of thermal expansion. Fiwok employs a high-pressure, constant 22°C temperature-controlled oil cooling system. By stabilizing the material's dimensions, we hit ±0.005mm tolerances consistently across small and medium batches.
Q: How does Fiwok ensure the straightness of micro shafts with high L/D ratios?
A: By utilizing Swiss-type CNC lathes with Synchronous Guide Bushing, we eliminate the deflection common in traditional turning. The material is supported directly at the cutting point, achieving high-precision straightness even on ultra-slender stainless steel parts.
