About Project

Are you looking for a reliable and professional CNC milling service for your mechanical products? If so, you should check out FacFox, a leading provider of high-quality CNC milling services in China. FacFox can make turned and milled parts using a wide range of plastic and metal materials, with scalable volumes, fast turnaround, and competitive prices.

One of the recent projects that FacFox completed was a CNC-milled SS316L coaxial feedthrough pin prototype. SS316L is a type of stainless steel that has excellent corrosion resistance and mechanical properties. A coaxial feedthrough pin is a component that allows electrical signals or power to pass through a vacuum or pressure barrier, while maintaining a seal. It is commonly used in applications such as vacuum chambers, medical devices, and instrumentation.

The coaxial feedthrough pin prototype that FacFox made consists of a rod and a disk, which are perpendicular to each other. The rod has a bigger hole on one end and a smaller hole on the other end, and is thick and short. The disk has a ring with a smaller diameter on it, which acts as a flange for mounting the pin on a wall or a plate. The prototype was made using a 5-axis CNC milling machine, which can achieve high precision and complex geometries. The prototype was also polished and inspected to ensure its quality and functionality.

FacFox is proud to showcase this CNC-milled SS316L coaxial feedthrough pin prototype as an example of its CNC milling capabilities.

  • Step 1: The part was designed in CAD software, and the dimensions and tolerances were specified.
  • Step 2: The CAD model was translated into a CNC program using CAM software, and the sequence of tools, the toolpath, the spindle speed, and the feed rate were specified.
  • Step 3: The CNC machine and the workpiece were set up, using a 5-axis CNC milling machine, a block of SS316L stainless steel, and various end mills and drill bits.
  • Step 4: The CNC program was executed and the part was produced, and material was removed from the workpiece by the rotating cutting edge of the tools. The cutting conditions and quality of the part were monitored.
  • Step 5: The part was finished, cleaned, inspected, measured, tested, packaged, and delivered to the customer.
