Efficient CNC Precision Milling For Long-Axis Stainless Steel Components

Product Overview

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.

Product Description & Key Features

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.

Product Customization

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.
