Custom CNC Precision Medical Shafts 0.5-20mm Diameter Up to 2000mm Length with HRC 40-55 Hardness
Our precision long slender shafts represent the pinnacle of medical device component engineering. Manufactured from superior stainless steel materials through advanced machining processes, these components deliver exceptional corrosion resistance, strength, and reliability for demanding medical applications.
Choose from 420J2, 17-4PH, and 304/316/316L stainless steel series with enhanced hardness and specialized performance characteristics.
State-of-the-art deep hole drilling technology ensures exceptional dimensional accuracy, straightness (≤0.01 mm per 100 mm), and internal surface smoothness.
Customized hardness levels through specialized heat treatment: 420J2 (HRC 50-55), 17-4PH (HRC 40-48), and 304/316 (HRB 75-95).
Meticulous polishing and finishing processes create burr-free, biocompatible surfaces with Ra ≤ 0.2 μm.
