China China Titanium Medical Implant Bone Screw - Precision Machining by Leading Suppliers and Factory Service, Products
Product Description
Product Overview
Manufactured from Titanium Alloy (Ti-6Al-4V), it is used in orthopedic surgery. The part requires extreme precision, biocompatibility, and a burr-free finish. Sunmy Hardware utilizes advanced Swiss-type CNC lathes to produce such micro-components.
Manufacturing Process Insight
Swiss Turning
The guide bushing technology supports the workpiece close to the cutting tool, minimizing vibration. This allows us to turn long, slender parts with zero deflection.
Thread Whirling
We use a specialized thread whirling attachment to cut the deep, sharp bone threads in a single pass. This results in superior surface quality and faster cycle times compared to single-point threading.
Deburring & Cleaning
Parts undergo ultrasonic cleaning and microscopic inspection to ensure no foreign particles remain.
Key Features & Benefits
Biocompatibility
Titanium Grade 5 is lightweight, non-magnetic, and biologically inert, making it safe for long-term implantation.
Micro-Precision
Tolerances are held to ±0.005mm to ensure secure engagement with surgical tools.
Surface Integrity
A smooth surface finish prevents tissue irritation and bacterial growth.
Traceability
Full material lot traceability is maintained for every batch, crucial for medical compliance.

Don't let tolerance stack-up delay your product launch. Submit your project details, and our engineering team will evaluate your design for manufacturability before the first cut.
Q1: What material grade is used for orthopedic implant screws?
We use Titanium Alloy Ti-6Al-4V (Grade 5), which meets ASTM F136 standards for surgical implant applications. It offers an excellent strength-to-weight ratio and full biocompatibility for long-term implantation.
Q2: What tolerances can you achieve on micro-turned medical components?
Our Swiss-type CNC lathes routinely achieve dimensional tolerances of ±0.005mm. For critical mating features such as hex drives and thread forms, we maintain tight process controls with 100% inspection on key dimensions.
Q3: How do you ensure the parts are completely burr-free?
After machining, all parts go through ultrasonic cleaning followed by microscopic visual inspection. Any component that does not pass our burr-free and cleanliness criteria is rejected before packaging.
Q4: Can you support low-volume prototype orders as well as high-volume production?
Yes. We support prototype quantities starting from 50 pieces all the way to high-volume production runs in the tens of thousands. Our Swiss lathes are highly efficient for both short and long runs.
Q5: What documentation do you provide for medical-grade parts?
We provide full material certifications (EN 10204 3.1 Mill Certs), dimensional inspection reports (CMM or optical comparator), and, upon request, PPAP documentation and First Article Inspection (FAI) reports to support your regulatory compliance.
Q6: What is your typical lead time for CNC-machined titanium medical components?
Standard lead times range from 15 to 25 business days depending on complexity and quantity. Expedited production can be arranged for urgent orders. Please contact us with your drawings for a precise timeline and quote.
