Long Axis Precision CNC Lathe Milling For Metal Machinery Parts

Our precision long slender shafts represent the pinnacle of medical device component engineering. Manufactured from superior stainless steel with state-of-the-art processes, they are designed to deliver unmatched reliability, accuracy, and performance in the most demanding medical applications.

These medical device accessory shafts are engineered for applications requiring exceptional precision, smooth actuation, and long-term reliability. Their high length-to-diameter ratio is achieved through advanced manufacturing techniques.

• Premium Material Integrity: Fabricated from superior-grade stainless steel, offering exceptional corrosion resistance and high tensile strength for longevity and reliability.

• Precision Deep Hole Machining: Utilizes meticulous deep drilling techniques to achieve exceptional dimensional accuracy, straightness, and internal surface smoothness critical for high-performance medical devices.

• Advanced Surface Finishing: Each shaft undergoes a specialized polishing process to achieve a flawlessly smooth, burr-free surface. This ensures patient safety, minimizes tissue trauma, and allows for easy sterilization.

• Thermal Management Manufacturing: The integration of advanced cooling systems during the deep hole machining process prevents thermal deformation, preserves the material's metallurgical properties, and significantly enhances the product's fatigue life and durability.

We provide comprehensive customization services to meet your specific design and application requirements:

• Dimensional Tailoring: Custom outer diameters, inner diameters (for hollow shafts), lengths, and specific tolerance classes (e.g., ±0.01mm).

• Material Selection: Choice of specific stainless steel grades (e.g., 304, 316, or 316L VM) based on application-specific regulatory and performance needs.

• End-Finishing & Geometry: Custom machining of shaft ends (e.g., threading, flat milling, notching) to interface with specific components.

• Surface Treatment Options: Variety of finishes available, including electropolishing for enhanced corrosion resistance and cleanability.

• Primary Process: Precision Deep Hole Drilling (e.g., Gun Drilling, BTA Drilling)

• Supporting Processes:

  1. CNC Turning and Grinding for OD precision

  2. Advanced Micro-Polishing and Electropolishing

  3. Advanced Cooling and Lubrication Systems

• Quality Control: In-process monitoring and final inspection for straightness, diameter, surface roughness, and burr-free edges.

• Surgical Robotics: Critical force-transmitting components within robotic surgery systems.

• Endoscopy: Shafts for flexible and rigid endoscopes and biopsy channels.

• Orthopedic Devices: Guide wires and drive shafts for bone drills and saws.

• Drug Delivery Systems: Precision components in injectors and infusion pumps.

• Diagnostic Sensors: Protective sheaths and guides for sensor probes.

Stainless steel long slender shaft medical device accessories, made of high-quality stainless steel material, have excellent corrosion resistance and strength. The deep machining process is exquisite, ensuring the accuracy and smoothness of the shaft, suitable for high-precision medical equipment. The surface of the long slender shaft is finely polished, smooth the touch, no burrs, ensuring safety and comfort during use. In the deep hole machining process, advanced cooling systems and precision tools are used to effectively prevent material deformation and product durability. This accessory is widely used in minimally invasive surgical instruments, diagnostic equipment and other high-end medical fields, and is an indispensable part of modern medical technology.
