    Part Categories We Machine

    Bracketry & weapon mounts

    5-axis milled aluminum and stainless brackets, picatinny-rail components, and weapon-system mounts machined from billet to drawing tolerance.

    Antenna & sensor mounts

    Lightweight aluminum and titanium mounts for ground-based and airborne RF, EO/IR, and SIGINT payloads.

    Ground support equipment housings

    Enclosures and chassis for GSE, test fixtures, and field-deployable electronics, with documented material certs.

    Bushings, bosses & precision fittings

    Live-tool turned components on the Chien Wei CWB-450-CNC for hydraulics, pneumatics, and structural attachments.

    Fixtures & tooling for prime depots

    Custom CNC-machined fixtures supporting overhaul, repair, and rework lines at depot and OEM facilities.

    Representative Case Studies

    Anonymized program summaries. Customer and program identifiers withheld under NDA / ITAR.

    5-Axis Titanium Antenna Mount for Airborne SIGINT Payload

    Material: Ti-6Al-4V · Tolerance: ±0.0005″ true position · Qty: 40 units

    Challenge: Tier-1 prime needed a lightweight, vibration-isolated antenna mount with thin-wall pocketing and tight position tolerance between the RF interface bore pattern and the airframe mounting datum. Prior supplier produced parts that passed dimensional inspection but failed installation fit-up due to residual stress distortion.

    Approach: Re-toleranced the datum reference frame during DFM review, switched stock from plate to forged billet to reduce residual stress, fixtured on a 5-axis Haas with soft jaws machined from the part model, and added an intermediate stress-relief between roughing and finishing operations. Full AS9102 Rev C FAI with CMM Form 3 against the ballooned drawing.

    Outcome: 100% first-pass acceptance at customer source inspection across 40 units. Installation fit-up issue eliminated. Program extended to follow-on lot of 120 units under blanket PO.

    Aluminum Picatinny-Rail Component for Land-System Weapon Mount

    Material: 6061-T6 · Tolerance: MIL-STD-1913 profile · Qty: 500 units across 4 releases

    Challenge: Defense OEM transitioning from prototype to production needed dimensional consistency across scheduled releases over an 18-month period. Critical concern was lot-to-lot variation on the rail profile, which had to interchange with any mount conforming to MIL-STD-1913.

    Approach: Locked the prototype CNC program and setup sheet as the production baseline. Each release runs the same probe-verified setup, same tool list, and the same CMM cycle on the Chien Wei CWB-450-CNC. SPC sampling on the rail profile generated Cpk > 1.67 on the critical-to-quality features.

    Outcome: Zero non-conformances across four production releases. Customer eliminated incoming inspection on the part number after the third release based on documented process capability.

    Inconel 718 Bushing for Ground Support Equipment

    Material: Inconel 718 · Tolerance: ±0.0003″ ID · Qty: 25 units (FAI + pilot)

    Challenge: Aerospace subtier needed a small lot of high-temperature bushings with a tight ID tolerance and a passivation special-process callout. Two prior shops had quoted but declined due to material handling and process-flow-down requirements.

    Approach: Sourced certified Inconel 718 bar with mill test report tied to heat and lot. Live-tool turned on the Chien Wei CWB-450-CNC with carbide tooling rated for nickel-superalloy work and a controlled feed-per-rev to manage work hardening. Routed passivation to an approved processor and verified on receipt against the special-process callout on AS9102 Form 2.

    Outcome: FAI accepted on first submission. Material certs, special-process certs, and CoC delivered in customer-template format. Customer added Olympus to approved-supplier list for follow-on superalloy work.
