CNC Machined Aluminum Surgical Navigation Tracker Frame
This product case focuses on a CNC machined aluminum frame used in a surgical navigation tracker assembly. The part supports marker ball posts or sensor references while keeping the assembly light enough for use on instruments, fixtures or calibration accessories. The main manufacturing challenge is to combine low weight with stable datums, reliable threaded holes, cosmetic black anodizing and controlled packaging.
Application
The frame can be used in optical navigation trackers, robotic surgery accessories, orthopedic guide instruments, calibration tools and medical imaging support fixtures. It is suitable for prototypes, pilot builds and low-volume precision production.
Material and Finish
6061-T6 aluminum is a practical option for balanced machinability and anodizing response. 7075-T6 may be selected when higher stiffness and strength are needed. Black anodizing provides corrosion protection and a low-reflection appearance, while stainless steel posts and screws can be supplied as mating hardware.
Machining Features
The frame includes weight-reduction pockets, marker-post bosses, threaded holes, datum pads, chamfers and cosmetic exterior contours. Multi-axis machining helps maintain access to pockets and side features, while dedicated fixtures support thin arms and reduce clamp marks.
Quality Control
Inspection can include flatness, profile, true position of marker holes, thread quality, boss height, datum pad height, anodized surface condition and assembly fit with posts or screws. CMM reporting is recommended for marker-coordinate relationships.
Packaging and Supply
Frames can be packed individually in foam trays with posts, screws and accessories separated. Lot labels, inspection reports and material certificates can be prepared according to the purchase order.
FAQ
Can the tracker frame shape be customized?
Yes. Overall shape, pocket layout, marker positions, thread pattern, material and anodizing can be made to customer drawings.
Is black anodizing available?
Yes. Black anodizing can be provided, with attention to masking, coating thickness and cosmetic handling.
Can marker posts and screws be supplied together?
Yes. Frames, posts, screws and small accessories can be supplied as a kit or packed separately.
What inspection is recommended?
CMM inspection for marker positions, flatness and datum pads is recommended when calibration accuracy is important.
Can prototype quantities be made?
Yes. Prototype and small-batch orders are suitable for surgical navigation device development.
How are cosmetic surfaces protected?
Parts can be separated in foam trays or bags to prevent rubbing marks, especially after black anodizing.
