Aluminum Slit Production Housing

Precision CNC Machining

Precision Custom CNC Machining of an Aluminum Slit Production Housing for the Analytical Instrumentation Industry

Alpine Precision provided the custom CNC machining for this aluminum housing which was used by a customer in the analytical instrumentation industry. This precision component is designed to control light input for a spectrometer.

The part was machined from 6061-T6 aluminum and required mill profiling, pocketing, mill slots, drilling, counterboring and tapping as well as a black anodized finish. Measuring 4.125″ long, 3″ wide and .800″ high, it also met tolerances of +.0002″/-.0000″, flatness of .001″ and perpendicularity of .003″.
