Advanced Precision Machining

What Advanced Precision Machining does

Advanced Precision Machining, LLC (APM) is a precision CNC machining and fabrication shop founded in 1989 and headquartered at 1649 Monrovia Avenue, Costa Mesa, California. It operates as a custom, quote-based job shop producing tight-tolerance components, sub-assemblies, and technical assemblies for four primary verticals: Medical and Dental (e.g., da Vinci Surgical System, laparoscopic, and dental instrument components), Aviation (flight deck, galley, and lavatory parts for commercial and military aircraft), Defense (Apache and Cobra helicopter components, arms, armaments, and targeting systems, with Prime Contractor status to the U.S. Government), and Aerospace (telecommunications, weather tracking, missile defense, and geo-positioning parts).

The shop floor combines DMG MORI NLX 2500 and NLX 2000 turning centers with BMT technology, a CMX 1100 V, a FANUC Robodrill D21MIB5 with optional 24,000-RPM spindle, and a DMG MORI FANUC Collaborative Robot Cell (CRC) for unattended lights-out manufacturing. Inspection is conducted on Zeiss Contura G4 and DuraMax coordinate measuring machines equipped with VAST XXT scanning sensors, plus an iNEXIV VMA-2520 multi-sensor benchtop system. Process discipline is anchored in Japanese methodologies — Kaizen, Lean Six Sigma, and Poka-Yoke (error-proofing) — supported by 6S shop organization and the DMG MORI Academy for ongoing training.

APM runs a direct sales, quote-based revenue model: customers submit specifications through a Request Quote form on its website, and pricing is determined per job by complexity, materials, and volume. Demand is concentrated in enterprise and government channels, including Meggitt Defense, AVON (Avon Protection), Honeywell Safety Products, Groth, the Defense Logistics Agency (DLA), the Naval Surface Warfare Center, and Pro-Dex. The business is supported by AS9100D and ISO 9001:2015 quality certifications, CMMC Level 3 and NIST 800-171 cybersecurity compliance, ITAR registration, and HUBZone/EDWOSB/WBENC small-business set-aside certifications. On February 9, 2026, the company was acquired by Pro-Dex, Inc. (NASDAQ: PDEX) for approximately $8.65 million, funded by a $6.65 million loan and a seller note; APM operates as a wholly-owned subsidiary of Pro-Dex.
