High Light Grade 304 Stainless Steel Medical Machining Parts ，Biocompatible CNC Milling Parts ，Tight Tolerances Precision Medical Components

Product Description

This product refers to high-precision, miniaturized, or complex-shaped zero (accessory) parts manufactured through Computer Numerical Control (CNC) milling processes, specifically using Grade 304 and Grade 316L stainless steel. These materials are selected for their excellent corrosion resistance, biocompatibility, and mechanical properties, making them ideal for demanding medical environments. The parts are characterized by tight tolerances, superior surface finishes, and intricate geometries, meeting the stringent requirements of modern medical device assemblies.

Product Processing



Processing Stage Key Details & Characteristics
Primary Material Austenitic Stainless Steel: 304 (General corrosion resistance) / 316L (Enhanced corrosion & pitting resistance, lower carbon content).
Core Machining Multi-axis (3/4/5-axis) Precision CNC Milling.
Key Capabilities Complex contouring, micro-milling, deep cavity machining, threading, undercutting.
Tolerance Control Extremely tight dimensional and geometric tolerances, typically within ±0.01mm to ±0.05mm (±0.0004" to ±0.002").
Surface Finish Fine machined finishes; can achieve Ra < 0.8 µm (32 µin) or better. Optional electropolishing for enhanced performance.
Secondary Operations Deburring, cleaning, passivation (for 316L especially), ultrasonic cleaning, laser marking.
Quality Assurance 100% Dimensional inspection (CMM, Optical Comparators), material certification, documentation per ISO 13485.

Product Applications & Uses

These precision components serve as critical building blocks within various medical devices and systems:

  • Surgical Instruments: Components for laparoscopic tools, surgical handpieces, biopsy devices, orthopedic instruments.

  • Diagnostic & Imaging Equipment: Probes, sensor housings, connectors, and brackets for MRI, CT, ultrasound, and patient monitoring systems.

  • Implantable Device Components: Structural parts, housings, and connectors for pacemakers, neurostimulators, drug pumps (primarily 316L).

  • Dental & Orthopedic Devices: Custom abutments, surgical guide components, small bone plates, and trial instrument parts.

  • Drug Delivery Systems: Precision parts for insulin pumps, inhalers, and infusion sets.

  • Laboratory & Analysis Equipment: Components for fluidic systems, valves, and connectors in automated analyzers.

Product Technical Parameters



Parameter Category Specification Details
Material Standards ASTM A240 (304 / 316L), ISO 7153-1, ISO 5832-1 (316L for implants).
Primary Process Precision CNC Milling (3/4/5-Axis).
Standard Tolerance ISO 2768-mK or better. Commonly held at ±0.025 mm (±0.001").
Geometric Tolerance Straightness, flatness, concentricity typically within 0.01mm - 0.03mm.
Surface Roughness Standard: Ra 1.6 µm (63 µin). High-Precision: Ra 0.4 µm - 0.8 µm (16-32 µin) achievable.
Part Size Range Typically from <1 mm to 300 mm in maximum dimension.
Key Features Thin walls, micro-holes, complex 3D contours, fine threads, high aspect ratio features.
Biocompatibility 316L is preferred for prolonged internal contact. Both grades comply with ISO 10993-1 evaluation.
Surface Treatment Passivation per ASTM A967, Electropolishing (common for 316L).
Cleanliness & Packaging Cleaned to particulate-free standards, packaged in controlled environments.
Quality Standards Manufactured under quality management system compliant with ISO 13485:2016.
