CNC Machining Surgical Probes: Precision Manufacturing for Medical Applications

Surgical probes are essential components in advanced diagnostic and surgical tools. Designed for contact with tissue, these parts demand superior precision, cleanliness, and biocompatibility. With CNC machining services tailored for the medical device industry, Neway delivers end-to-end solutions that comply with stringent regulatory and performance requirements.

Our expertise in stainless steel probe manufacturing combines advanced CNC turning and CNC milling with validated post-processing, enabling high-quality instruments ready for clinical use.

Material Selection – Why 316L Stainless Steel for Surgical Probes

Biocompatibility and Corrosion Resistance

316L stainless steel, known for its low carbon content and high corrosion resistance, is a gold-standard material for implantable and surgical components. Meeting ASTM F138 and ISO 10993 standards, it is frequently used in applications requiring sustained contact with tissue or fluids. Its performance in humid, high-temperature, and chemical sterilization conditions makes it ideal for reusable stainless steel CNC machined parts.

Machinability in Tight Tolerance Environments

316L offers excellent machinability for small-diameter probes ranging from 1.0 mm to 5.0 mm. Our machining operations achieve tolerances of ±0.01 mm, making this alloy highly suitable for intricate shaft and tip geometries required in micro-surgical tools.

Precision Machining Workflow

CNC Turning for Tip Geometry and Shaft Accuracy

Utilizing Swiss-type CNC lathes, we machine shafts with long aspect ratios while maintaining concentricity and roundness. Probe tips—featuring radii under 0.4 mm—are formed with consistent edge finish and profile accuracy. Turning ensures optimal symmetry and minimal deviation, essential for hand-held surgical tools.

CNC Milling for Structural Features and Handling Geometry

Multi-axis milling is employed to form alignment flats, grip textures, and connector interfaces. Using multi-axis CNC machining, we eliminate cumulative tolerance stack-up across features, improving assembly accuracy with electrosurgical handles or diagnostic probes.

Surface Finish Requirements and Post-Processing

Passivation for Medical-Grade Cleanliness

To remove free iron and enhance corrosion resistance, we perform chemical passivation in accordance with ASTM A967. This process is conducted in an ISO-controlled environment, delivering contaminant-free, passivated stainless steel surfaces suitable for surgical use.

PVD Coating for Wear and Aesthetic Enhancement

For enhanced wear performance and visual identification, TiN and ZrN coatings are applied via PVD coating. These coatings raise surface hardness to above 1800 HV and provide vibrant color coding for different probe types.

Dimensional Control and Quality Assurance

Each probe is subject to full dimensional verification using CMM inspection and surface profilometry. We maintain Ra ≤ 0.4 µm for clinical smoothness. Supporting precision machining standards, we also provide complete traceability, COC, RoHS, and REACH documentation per batch.
