We will evaluate a component to determine the best inspection method for each feature, and then add it to the part’s documentation. If we don’t have a tool that we need, it will be acquired. Some examples of our selection of inspection methods include:

• Threads are measured with ground thread plugs or rings
• Internal diameters are measured with digital bore gages with .00001 resolution
• Feature locations are measured on a Mitutoyo comparator or digital height gage
• Outside features are measured with .0001” resolution micrometers
• Visual inspections are performed under 3x – 10x magnification

Marchton automation is here to make the best parts possible and we know how important it is to have the right tools for the job.

Inspection equipment and gaging are assigned unique serial numbers and controlled through a gage maintenance program. All gaging is calibrated and traceable to NIST standards. Annual gage calibrations are performed by an external, independent metrology lab.

First piece inspections are performed on all parts. The first piece consists of 100% inspection of features created at a specific operation, and is documented on the inspection report. Following the first piece inspection, the part receives in-process inspections to insure that the part remains conformant to print and that the process is stable throughout the operation.

Component inspection and metrology is an extremely important element to producing high quality products. Equally important is the Procedures and Systems that a manufacturer uses throughout the entire process.
