Medical Taper Threading Milling Cutter ASTM F543 Bone Cutting
Introduction:
This specialized taper thread milling cutter is designed for manufacturing bone screws and orthopedic implants compliant with ASTM F543 (Standard Specification for Metallic Medical Bone Screws). It ensures high precision, biocompatibility, and superior surface finish for medical-grade applications.
Designed for cortical and cancellous bone screw threads.
Meets dimensional tolerances per ASTM F543 Class 1 (Stainless Steel) & Class 2/3 (Titanium Alloys).
Taper Angle: Typically 1°–10° (adjustable per implant design).
Thread Profile: Optimized for V-thread or buttress thread (common in bone screws).
Pitch Range: 0.5 mm – 2.0 mm (covers most medical screw sizes).
Tool Material: Ultra-fine carbide substrate (high wear resistance).
Coating: AlCrN (Aluminum Chromium Nitride) or DLC (Diamond-Like Carbon) for:
Biocompatibility (FDA-compliant).
Extended tool life in titanium (Ti-6Al-4V) and stainless steel (316L).
Thread Accuracy: ±0.005 mm (critical for implant fit).
Surface Roughness: Ra ≤ 0.4 µm (minimizes bacterial adhesion).
| Bone Screw Type | Thread Design | Typical Materials |
|---|---|---|
| Cortical Screws | Fine, sharp threads | 316L Stainless Steel |
| Cancellous Screws | Coarse, deep threads | Ti-6Al-4V, PEEK |
| Locking Screws | Self-tapping, dual-lead | CoCr Alloys |
| Parameter | Value Range | Notes |
|---|---|---|
| Cutting Speed (Vc) | 15–30 m/min | Lower for stainless steel |
| Feed per Tooth (Fz) | 0.02–0.05 mm/tooth | Adjust for thread pitch |
| Coolant | MQL (Minimum Quantity Lubrication) or sterile saline | Avoids contamination |
| Tool Life | 100–300 holes (varies by material) | Monitor wear closely |
Fixed taper angle (e.g., 2.5° for dental implants).
Best for high-volume production (e.g., spinal screws).
CNC-programmable taper (1°–5° via toolpath).
Ideal for R&D & custom implants.
Combines drilling & threading in one operation (reduces alignment errors).
