CNC Machined Black Anodized Aluminum CT Detector Carrier Frame
Product Overview
This product case focuses on a black anodized aluminum CT detector carrier frame used in medical imaging equipment. The component has a large central window, multiple counterbores, dowel holes, alignment slots, lightening pockets and flat mounting surfaces. Its function is to support detector or sensor modules in a stable position while keeping the assembly lightweight and serviceable.

Customer Requirement
The customer required a prototype batch for imaging module assembly verification. The frame needed stable flatness, controlled hole relationships, clean cosmetic surfaces and a dark anodized finish. Because the part sits near sensitive detector and optical components, burrs, scratches and reflective surfaces had to be controlled. The drawing review focused on datum faces, coating allowance and inspection points.

Manufacturing Approach
The raw aluminum plate was rough machined first to release stress around the central window and pockets. Semi-finishing stabilized the outer profile and ribs. Final finishing created the dowel holes, counterbores, alignment slots and seating surfaces. The process used a dedicated fixture to support the wide frame and reduce vibration. After machining, the part was deburred, cleaned and prepared for black anodizing.

Inspection and Quality Control
Inspection checked flatness, hole position, counterbore depth, slot width, profile tolerance and coating-sensitive dimensions. Gauge pins verified dowel fit, while optical inspection reviewed edges and cosmetic surfaces. After anodizing, key dimensions and surface condition were checked again so the frame could be used directly in prototype assembly.

Result
The finished carrier frames provided clean appearance, accurate alignment features and protected delivery condition. The case shows how CNC machining and surface treatment planning support medical imaging equipment development when geometry, coating and clean handling are considered together.
FAQ
What material is used for this carrier frame?
The frame is machined from aluminum and finished with black anodizing for appearance and reduced reflection.
Which features are most critical?
Flat seating surfaces, dowel holes, counterbores, alignment slots and the central window profile are critical.
Why use black anodizing?
Black anodizing reduces reflection, improves surface consistency and protects aluminum in the equipment assembly.
How is frame deformation controlled?
Stress release, balanced roughing, stable fixturing and final finishing passes help control deformation.
Can coating allowance be included?
Yes. Holes, slots and masked areas can be planned according to coating thickness requirements.
Is this suitable for prototype batches?
Yes. CNC machining is suitable for prototype and low-volume detector carrier frames.
