CNC Milling of Aluminum Thermal Block Test Plate for an Optical Application

Thermal Block Test Plate
Thermal Block Test Plate

With years of experience machining precision instrumentation optical components, RTMA (Rochester Technology and Manufacturing Association) is frequently contracted by clients in the medical industry to manufacture critical-to-function products. Our expertise, combined with our commitment to quality, led a German-based client to entrust RTMA with the construction of a thermal block test plate for an optical application. Possessing over 5,000 dimensions, the complex plate was fabricated to meet precise client requirements.

Relying on our 5-axis, Mori Seiki NV5000 vertical machining center with automatic pallet changer to construct the plate, the component measured 4.681 inches in overall length, 3.261 inches in width, and .560 of an inch in height. Made from 6063-T5 aluminum material, the plate featured a 32 RMS electroless nickel finish, in accordance with AMS 2404 specifications. To ensure all requirements were met, we held true position tolerances down to .005 of an inch, and flatness tolerances down to .002 of an inch. We also performed in-process testing, overseen by our quality supervisor.

The final thermal block test plate was ROHS compliant, and met our client's requirements for design, quality, and precision. Upon completion, we delivered the optical component to our client's facility in Germany. To learn more about this precision component and other projects, please contact RTMA today.
