Specification for Optical Comparator at Arnold Air Force Base, TN; Arnold Engineering Development Complex

(AEDC)

The specific machine brand/model is the Starrett HF750 Series Optical Comparator. This machine will be an integral part of the inspection process at the Model Shop precision inspection lab and is one that will be utilized daily for small, hard to measure features that standard measurement equipment cannot achieve. The comparator is needed to fully support AEDC’s test cells and ensure parts and assemblies conform to their respective drawing requirements before being delivered to the end user.

Due to existing software, similar purchased comparators, periodic service and calibration requirements, any other machine or machine software combinations will need to be reviewed and approved by the requestor prior to purchase.

Provide all materials, labor, and equipment necessary to provide a new fully functional Optical Comparator. Refurbished or remanufactured machines or parts are not authorized for this requirement.
