This is some of the flat work machined in house, the one is .003" thick Capton material. The next one is bakelite and one is 2025 aluminum with .0005" true position locations.
This is a part for an aerospace application made out of hard brass. It is made out of a solid plate and is .006" +/-.001 thick with most of the other tolerances +/-.001". The customer had a stack of no-quotes 3" high. Diligence, Inc. tackled the job and made it profitable.
This is a part made for NASA. Made out of 316 SS with a 20.625" length and an O.D. of .937" +.001/-.000 , an I.D. of .860" +.001/-.000 which creates a .040" wall thickness. The tube has a straightness callout of .002". If that wasn't complex enough, it has 6 grooves around the outside that are .011" +.001/-.000 wide and .012" deep. These grooves go the length of the tube and follow the contour down and line up with (6) .016" dia. holes that are .937" deep. This job was lost to a lower bidder, but we got it back because they couldn't make the part. We thank God for the opportunity to do this project.
This part was the reason we got a shot at the other tube. This one also had the other close tolerances and the grooves, but didn't have the welded on nose.
These are titanium transducers. The longer part has (2) .031" wide arcs that are right next to the .250" dia. shaft. the arcs were .090" deep and almost 2.5" away from the end of the part. The hole in the end was .0627" with a tolerance of +/-.0001. At the time we did it in house with our wire EDM.

This is a fixture that Diligence designed and built. It has pull back spring locators. Once the part was located and clamped, the locators could be moved out of the way. This was accomplished by using the machine in cycle to trip the handles. Diligence also programmed and set up this fixture at the customers site.
These are some of the other fixtures that were built for this customer. They are all hardcoated aluminum for durablility and many years of use. The Parts held are made out of magnesium and Diligence Programmed, ordered tools and set the jobs up. The customer was very happy with the results.
This is a Diligence designed and built optical gaging fixture for a Smart Scope. It is held in a clamping fixture that locates the fixture on the top surface of the Smart Scope table. The fixtue holds 25 parts vertically and 25 parts horizontally. All locators are self contained to keep out any contaminants. It is made out of 6061 aluminum and hardcoated for durability. It has finger pull back tabs for operator loading. Clearance is made all the way around the part for visual inspection.
This is a Diligence designed and built optical gaging fixture for a Smart Scope. It is held in a clamping fixture that locates the fixture on the top surface of the Smart Scope table. The fixtue holds 50 parts vertically and 50 parts horizontally.
The customers parts were very tiny rings that needed to be measured vertically and horizontally within a few tenths. They also wanted the fixture to measure five different sizes. The smallest ring is .028" in diameter and the largest is .089" diameter. Wall thickness is .003".
Diligence designed and built this fixture to satisfy the customers requirements. Each fixture block containes a vertcal and horizontal spring locator plus a 3 position main locator to cover all of the different size rings. All locators are self contained to keep out any contaminants. The plungers come in at 7 degrees to give downward pressure at the same time they locate the part. The stainless steel threaded screws are covered with a hypodermic tube to create a smooth feel. The fixture is made out of 6061 aluminum and hardcoated for durability. The horizontal parts locate on a hard acrylic transparent pad. This fixture contains over 1000 components.
Here is the fixture in Diligence's optical comparator at 50X magnification. These two pictures show the minimum and maximum sizes this fixture locates. The locator is coming in from the right side. These are the horizontal oriented parts.
This is one side of a fixture system for the Dana Corporation that was designed by Diligence Inc. The setup simultaneously held 16 parts. A special locating pin was designed to make the fixture endure many cycles.
