This is a comprehensive list of NTS Amega Global’s Deep Hole Drilling Capabilities, our global facilities utilize processes, equipment enhancements/modifications, and tooling for the following:
Concentric holes with extremely tight positional tolerances
a. Drill concentric Bores ID larger than 0.75” (BTA drilling)
b. Drill concentric thin wall tubing of ID larger than 0.75” with extremely thin walls relative to their OD size.
c. Drill concentric Bores ID less than 0.75” (gun drilling):
d. Drill concentric thin wall tubing of ID = -0.75 with extremely thin walls relative to their OD size.
Eccentric (off-center) holes with extremely tight positional tolerances
a. Drill eccentric Bores ID greater than 0.75
b. Drill eccentric Bores ID less than 0.75
Angled holes with extremely tight positional tolerances
a. Drill angled bores ID greater than 0.75
b. Drill angled bores ID less than 0.75
Drill complex form features.
Creating custom shapes at the bottom of bores and custom transitions between bores in the form of shoulders, radiuses, chamfers, and multiple-angle chamfers.
Drill deep but short-length seal bores
Creating deep but short-length seal bores that are too short to produce with a honing operation.
Drill Bottle Bore shapes
Machine “bottle bores”. Bottle boring refers to machining an internal profile within a part that is larger than the ID at the face of the part. These features can be machined at up to 20 feet from one end. CNC controlled.
Drilling to reconnect wire passages on stub welded repairs
small diameter holes through stub weld additions.
Drill by pull boring
0.50-6.50 dia range. Specialty-designed tooling and processes for unusually small diameters.
Drill by trepanning
Trepan holes yielding commercially valuable cores of exotic alloys.
Drill-interrupted parallel holes
Produce parallel overlapping holes used for creating fluid by passage, wire by passage, and mechanical keying features.
Drill deep depth counter boring
Counter boring with tight concentricity to other bores.
Drill short-length parts on long-bed drilling machines
Short-length parts that would otherwise be outside the capabilities of long-bed drilling machines.
Compression burnishing
Diametrically compress the bore surface of the ID.
Hone thin wall tubing
Honing thin wall tubes with no or minimal part deformation.
Hone small dia bores very deep
Examples: 0.500 +/-.001 dia in 136.00 long part and 0.750 dia 16 Rms in 262.00 long part
Hone small dia and short depth seal bores
Honing small diameter bores that are shallow on the face of large parts. For example, a connector seal bore: 0.250 +/-.001 32 Rms x 4.00 deep.
Hone short length undersized hone tapers
Producing short undersized hone tapers at the bottom of bores.
Inspect and document X-Y position of eccentric holes ID greater than 0.75
Measure the X-Y location and Polar location and Cartesian location of a drilled hole along its entire depth
Inspect and document X-Y position of eccentric holes ID less than 0.75
Measure the X-Y location and Polar location and Cartesian location of a drilled hole along its entire depth
Inspect bore straightness
Measuring the straightness of bores regardless of OD configuration. Allows straightening bores that do not pass the required drift.
Inspecting surface finish in deep bores
Measure the surface finishes of bores beyond the depth limitation of commercial equipment.
Pin ring removal
Remove field-damaged pin rings in the Halliburton HOC product line
Pin ring insertion
Install replacement pin rings in the Halliburton HOC product line. Ensures accurately oriented and fully seated rings.
Tool management
Tightly organized and controlled tool room management that provides readily available durable tooling and consumable tooling.
Tooling requirement
Listing required drilling tooling on every work order.
Scheduling
Managed scheduling by machine and by individual operator
