D&E Machine Company recently CNC machined 3 metering adjustment cones for the oil field industry. These cones are a component of a down-hole testing machine used for oil wells. Based on customer supplied drawings, the cones were constructed from 4130 hot finished steel to measure precisely 11 inches in length and 3 inches in diameter, with a 1 inch wall thickness. In addition, the material used for making these cones was quenched and tempered 125 KSI minimum per client specifications.

After the part was machined complete, we then performed full dimensional inspections of each part. Gages were supplied by the customer for checking each part’s accuracy.  In order to ensure that the cones met precise client specifications, we performed a series of magnetic particle, hardness, e-nickel, and zinc phosphate tests. We also made the cones traceable. Once assured that the metering adjustment cones met all of our client’s unique product requirements, we then delivered the completed units to our client’s facility in Texas.

Within a short, 8 week turnaround period, D&E was able to successfully manufacture 3 metering adjustment cones for the oil field industry, exceeding our client’s high expectations for quality.
