316 Stainless Steel Machined Parts for Medical Devices

Material:316 Stainless Steel

Finish:As Machined

Custom Machined Solutions for Dental and Surgical Tools, a custom CNC machined medical instrument handle—engineered for ergonomic use, consistent performance, and compatibility with high-precision procedures. Paired with a purpose-built holding fixture or assembly block.

Rollyu Precision offers high-precision CNC machined 316 stainless steel guide supports, widely used in dental equipment such as gutta percha cuttersintraoral scanners, and CAD/CAM systems. Manufactured through processes including CNC milling, cutting, grinding, and wire EDM, these components provide excellent dimensional accuracycorrosion resistance, and structural stability, making them ideal for use in dental robotics and diagnostic instruments.

The guide support (Part No. RY-H0001) features a tolerance of ±0.01mm and an as-machined surface finish, allowing for easy integration into dental handpiecesheating devices, and other precision assemblies. In addition to 316 stainless steel, we offer a variety of material options including aluminum alloysbrass, and engineering plastics, to meet diverse needs in custom dental applications.

Rollyu Precision is certified to ISO 9001:2015 and ISO 13485:2016, and we provide RoHS/REACH reportsmaterial certificates, and full NDA protection to ensure confidentiality of customer designs. Whether you require rapid prototyping or small-batch production, we deliver consistent and efficient support, accepting drawings in SolidWorks, AutoCAD, PRO/E, UG, and PDF formats.

Raw Material Preparation Medical-grade AISI 304 stainless steel
Selected in bar, rod, or billet form based on part geometry
Cut to size using bandsaw or automatic saw with tight length tolerances
Material is inspected for mill certification and surface defects
CNC Machining Operations Turning (if cylindrical features exist)
CNC lathe used for turning shafts, grooves, or chamfers
Precision facing, OD profiling, internal boring, and thread cutting (if required)
Milling
High-speed 3-axis or 5-axis CNC milling for:
Mounting holes, slots, precision flats, and alignment surfaces
Tapped holes for assembly or fastening within handle assemblies
Drilling & Reaming
Holes for guide pins, screws, or dowels
Reamed for tight tolerance and concentricity in high-precision applications
Surface Machining & Deburring
All sharp edges are deburred or chamfered for safe handling and smooth fit
Critical surfaces are milled with fine finish tooling or polished as needed
Surface Finishing Options based on application:
Passivation to enhance corrosion resistance and remove free iron
Electropolishing for a high-purity, ultra-clean surface
Glass bead blasting for matte finish (non-glare, easy to clean)
Polishing for ergonomic grip surfaces in handles
Quality Inspection Dimensional inspection using micrometers, CMM, and pin gauges
Thread verification, alignment checks, and surface roughness measurement
If used in medical equipment: inspection under ISO13485 or FDA-compliant procedures
Assembly & Packaging (Optional) Integrated into medical handle units or precision fixture assemblies
Sterile packaging or cleanroom-compatible wrapping available
Ensures the part is ready for immediate assembly in medical production lines.

FAQ

Why is 304 stainless steel commonly used for medical guide supports and fixturing?

Type 304 stainless steel offers excellent corrosion resistancebiocompatibility, and mechanical strength, making it ideal for medical environments. It’s suitable for repeated sterilization cycles (autoclave and chemical), ensuring durability in surgical and diagnostic applications.

What tolerances can be achieved for precision fixturing and medical handle components?

Using high-precision CNC machining, we routinely achieve tolerances as tight as ±0.01 mm, depending on part geometry and customer specifications. This level of accuracy ensures proper alignment and functionality in surgical instruments and modular fixturing systems.

Are the machined guide supports compatible with standard medical sterilization processes?

Yes. All 304 stainless steel parts are designed to withstand high-temperature autoclavingchemical disinfection, and repeated cleaning cycles without degrading surface finish or dimensional accuracy. Optional surface treatments (passivation, electropolishing) can further enhance corrosion resistance and hygiene.

Do you provide documentation for traceability and quality assurance?

Absolutely. We provide:

  • Full material certification (MTC)
  • Inspection reports (FAI, CMM data)
  • ISO 13485 compliance for medical device components
  • Lot tracking and serialization upon request
Can these components be customized for unique handle geometries or modular fixture designs?

Yes. We support customized geometriesthreaded features, and multi-axis contours based on your design requirements. With in-house 3D modeling, DFM support, and rapid prototyping, we help medical OEMs and device integrators bring precise, application-ready components to market faster.
