Premium Stainless Steel Material Balancing Corrosion Resistance and Mechanical Strength

High-Precision Swiss-Type Machining

Lightweight structural design with optimized annular grooves/chamfers for stress distribution

high surface finish reduces friction loss, enhancing wear resistance and service life

FAQs:

Q: What is the machining accuracy of this step shaft?

A: With Swiss-type CNC machining, the coaxiality of shaft diameters and steps can be controlled within ±0.005mm, and surface roughness Ra ≤ 0.8μm, meeting the tolerance requirements for precision transmission/connection.

Q: Does the material support other stainless steel grades (e.g., 303, 420)?

A: Customization is available! We can select different stainless steel grades (e.g., 304, 316L, 303, 420) according to your corrosion environment, strength requirements, or cost budget, or provide alternative materials like titanium alloy, aluminum alloy, etc.

Q: What is the minimum order quantity (MOQ) for small-batch customization?

A: The MOQ for small-batch Swiss-type CNC machining is usually 50 pieces (subject to evaluation based on part complexity, size, and process difficulty). Sampling confirmation is supported before mass production.

Q: What surface treatment options are available?

A: In addition to natural stainless steel, options include passivation, nickel plating, chrome plating, blackening (oxidation), etc., to enhance corrosion resistance or meet specific appearance requirements.

Q: What is the general delivery cycle?

A: Regular stock or simple-structured parts take about 5-7 days; customized parts (including complex grooves, special tolerances) require 10-15 days (including sampling verification time). Rush orders can be negotiated for expedited production.
