High-Precision CNC Knobs & Control Components for Critical Healthcare Applications
At Xierge Precision Machinery Co., Ltd., we leverage over 30 years of operational expertise since 1990 to manufacture high-precision CNC Knobs & Control Components for the global healthcare industry. Medical hardware—such as surgical instrument shafts, endoscopic connectors, orthopedic implant screws, and diagnostic equipment components—demands absolute micro-precision, flawless surface finishes, and strict biocompatibility. In medical applications, even a microscopic burr or a slight deviation in tolerance can lead to device failure or patient injury.
To meet these critical standards, our production facility is equipped with Japanese imported Star CNC Swiss-type lathes, advanced multi-axis machining centers, and precision grinders. This specialized equipment allows us to machine complex geometries, micro-threads, and deep internal bores in a single setup, ensuring extreme concentricity and eliminating secondary clamping errors. The Swiss-type guide bushing technology provides unparalleled support, enabling us to produce long, slender medical components with ultra-tight tolerances and superior cylindricity.
Following our core principle of "Integrity Oriented, Quality Foremost," we strictly adopt premium biocompatible raw materials, including 316LVM surgical stainless steel, Titanium Grade 5 (Ti-6Al-4V), and 17-4PH. To guarantee reliable product performance, we apply strict quality inspection protocols utilizing a complete set of testing instruments imported directly from Japan and Germany. We keep innovating to maintain sound business development, and we warmly welcome domestic and overseas clients to visit our factory and explore custom OEM/ODM cooperation opportunities.

Core Advantages of Xierge CNC Knobs & Control Components
- Biocompatible Material Mastery: We possess mature processing parameters for difficult-to-machine medical alloys like 316LVM and Titanium Grade 5, preventing work-hardening and ensuring structural integrity.
- Zero-Deflection Swiss Turning: Our Japanese Star CNC Swiss-type lathes provide continuous guide bushing support, enabling the machining of long, slender surgical shafts without bending or vibration.
- Burr-Free Single-Setup Machining: Multi-axis live tooling allows us to turn, drill micro-cross holes, and cut threads in one operation, drastically reducing handling errors and eliminating burrs in critical areas.
- Advanced Electropolishing Coordination: We machine internal bores and external surfaces to precise allowances, perfectly coordinating with electropolishing and passivation to achieve superior Ra 0.2 finishes and enhanced corrosion resistance.
- Ultra-Clean Processing Standards: To prevent biological contamination, all medical hardware passes through dedicated industrial ultrasonic cleaning machines to remove 100% of cutting fluids and micro-debris.
- World-Class Metrology Assurance: Utilizing imported Japanese and German CMMs and optical comparators, we verify micro-tolerances on complex geometries that standard hand tools cannot measure.
- 3-Decade Medical OEM/ODM Expertise: Since 1990, we have continuously innovated, providing DFM (Design for Manufacturing) optimization for custom medical devices, seamlessly scaling from rapid prototyping to high-volume production.
Payment Methods & Global Logistics Solutions
Secure International Payment Terms:
To facilitate smooth B2B international trade for our medical sector clients, we offer flexible and secure payment options. For mass production orders of CNC Knobs & Control Components, we accept standard T/T (Telegraphic Transfer) with a 30% advance deposit and 70% balance before shipment. For large-scale international supply contracts, we are fully capable of processing Irrevocable Letters of Credit (L/C) at sight. For initial prototyping, sample orders, or custom tooling fees, PayPal and Western Union are also available to expedite the process.
Global Logistics & Protective Packaging:
We provide comprehensive end-to-end shipping solutions under FOB, CIF, and DAP Incoterms. For urgent prototypes or small batches, we utilize expedited international couriers such as DHL, FedEx, and UPS. For bulk mass production, we offer highly competitive sea freight (LCL/FCL) and air cargo rates through our trusted global forwarder network. Recognizing that medical hardware requires absolute cleanliness and protection of micro-features, we utilize specialized packaging: each component is individually sealed in medical-grade cleanroom bags, protected by custom EPE foam slots or blister trays to prevent contact, and packed in sturdy export-grade cartons to ensure zero contamination or transit damage.
FAQ
Titanium is notorious for work hardening and rapid tool wear. We utilize specialized sharp carbide inserts with optimized coatings and strictly control our cutting speeds and feed rates on our Swiss lathes. This prevents excessive heat generation and material galling, ensuring the structural integrity and surface finish of the titanium medical hardware are not compromised.
Absolutely. We strictly source premium biocompatible raw materials from certified mills. For 316LVM surgical stainless steel, we provide full material traceability and certificates of compliance with ASTM F136 standards. This ensures the material meets the stringent chemical and mechanical requirements for surgical implants and medical devices.
Micro-features on medical hardware are critical and difficult to inspect. We utilize imported German and Japanese optical comparators, video measuring machines, and micro-probes on our CMM. For internal threads, we use precision precision Go/No-Go pin gauges and borescopes to verify 100% thread integrity and the absence of internal burrs.
Residual fluids can cause biological contamination or cytotoxicity. After machining and deburring, all medical hardware undergoes a rigorous multi-stage cleaning process in our dedicated industrial ultrasonic cleaning machines. This utilizes specialized medical-grade solvents and deionized water rinses to completely remove oils and particulates, ensuring pristine, ready-to-sterilize components.
Yes. While we excel at machining the components to micro-tolerances, we partner with certified medical finishing specialists for electropolishing and ASTM A967 passivation. We machine the surfaces to precise allowances, ensuring that after the material removal of the electropolishing process, the final dimensions still meet your exact specifications.
Yes. Our Japanese Star CNC Swiss-type lathes are equipped with live tooling and synchronized sub-spindles. This allows us to turn the shaft, drill deep blind holes, and mill custom bone screw threads on the back end in a single continuous operation, maintaining absolute concentricity and reducing lead times.
