China China Bone Screw Suppliers - Premium Titanium Medical Implants from Trusted Factory Exporters, Exporter
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.

Frequently Asked Questions
-
Q What tolerances can Sunmy Hardware achieve on titanium bone screws?We consistently hold tolerances to ±0.005mm on critical dimensions using our Swiss-type CNC lathes. This level of micro-precision ensures every part fits securely with surgical instruments and meets medical-grade specifications.
-
Q What grade of titanium is used for orthopedic implant components?We use Titanium Grade 5 (Ti-6Al-4V), which is the industry standard for orthopedic implants. It offers an excellent strength-to-weight ratio, is non-magnetic, corrosion-resistant, and biologically inert — ideal for long-term implantation in the human body.
-
Q What is thread whirling, and why is it preferred for bone screws?Thread whirling is a high-speed cutting process that produces deep, sharp bone screw threads in a single pass. Compared to conventional single-point threading, it delivers superior surface finish, tighter pitch accuracy, and significantly faster cycle times — all critical for high-volume medical part production.
-
Q How do you ensure parts are completely burr-free and clean?After machining, all parts undergo ultrasonic cleaning to remove any machining debris or coolant residue. Each component is then inspected under microscope to confirm a burr-free surface. This process ensures full compliance with medical cleanliness standards before packaging.
-
Q Do you support low-volume prototype runs for medical device development?Yes. We support both prototype and production volumes. For early-stage medical device development, we can produce small prototype batches with full inspection reports, allowing design engineers to validate dimensions and surface requirements before committing to full production.
-
Q What quality documentation do you provide with medical machined parts?Every batch is shipped with full material certifications (EN 10204 3.1 mill certs), dimensional inspection reports (CMM or first article), and lot traceability records. This documentation supports your regulatory submissions and quality management system requirements.
