Product Description
These stainless steel long slender shafts are precision-engineered medical device components. They are manufactured from high-grade stainless steel, ensuring exceptional corrosion resistance and mechanical strength. The entire machining process is meticulously controlled to guarantee outstanding dimensional accuracy and a perfectly smooth surface finish. Each shaft is finely polished to be burr-free, providing a smooth touch that ensures both safety and patient comfort during medical procedures.
Product Material
The shafts are crafted from high-quality, medical-grade stainless steel, typically Type 316 or 316L for its superior corrosion resistance and biocompatibility. This material is chosen for its ability to withstand repeated sterilization cycles (e.g., autoclaving) and harsh chemical environments without degrading.
Product Purpose & Applications
This component is an essential part of modern medical technology. Its primary applications include:
Minimally Invasive Surgical Instruments: Used as drive shafts, guide wires, pins, and connectors in endoscopic, arthroscopic, and laparoscopic devices.
Diagnostic Equipment: Acts as precise positioning shafts, guides, and probes in imaging and sensing devices.
High-End Medical Fields: Found in robotic surgery systems, dental handpieces, and other precision medical tools requiring reliable, slender, and strong mechanical components.
CNC Machining & Manufacturing Process
The production of these shafts involves advanced CNC (Computer Numerical Control) machining techniques:
Deep Hole Drilling: Utilizes specialized CNC deep hole drilling (e.g., gun drilling) with advanced high-pressure cooling systems. This effectively manages heat, prevents material deformation, and ensures hole straightness and surface integrity, crucial for product durability and performance.
CNC Turning & Grinding: Multi-axis CNC lathes and precision grinders are used to achieve the exact diameters, tight tolerances, and required surface smoothness.
Fine Polishing: Automated polishing processes are employed to achieve a flawless, micro-smooth surface finish, eliminating any microscopic burrs.
