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.

1. Key Features & Compliance

① ASTM F543 Compliance

• Designed for cortical and cancellous bone screw threads.

• Meets dimensional tolerances per ASTM F543 Class 1 (Stainless Steel) & Class 2/3 (Titanium Alloys).

② Taper Thread Geometry

• 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).

③ Material & Coating

• 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).

④ Precision & Surface Finish

• Thread Accuracy: ±0.005 mm (critical for implant fit).

• Surface Roughness: Ra ≤ 0.4 µm (minimizes bacterial adhesion).

2. Applications in Orthopedics

3. Machining Parameters (Ti-6Al-4V Example)

4. Tool Design Variants

① Single-Profile Taper Mills

• Fixed taper angle (e.g., 2.5° for dental implants).

• Best for high-volume production (e.g., spinal screws).

② Adjustable Taper Mills

• CNC-programmable taper (1°–5° via toolpath).

• Ideal for R&D & custom implants.

③ Hybrid (Drill + Thread Mill)

• Combines drilling & threading in one operation (reduces alignment errors).
