Equipment mounting plates, optical and laser adapter plates, faceplates, and gusset plates — milled flat, surface ground, and finished to print.
Mounting plates, adapter plates, and faceplates are the parts that decide whether the assembly above them lands true. An optical adapter plate that has to hold three mirror mounts coplanar within a tenth. An equipment mounting plate that has to bolt a heavy subassembly to a chassis without flexing the chassis or pre-loading the mounts. A faceplate that has to present a sealed pattern of fastener holes, connector cutouts, and engraved labels exactly where the mating panel expects them. A gusset plate whose hole pattern has to match a fifty-year-old bolt circle. These are the parts where flatness, hole-pattern true position, and edge condition are the whole job.
Quick Brown Fox Solutions is the prime contractor on this work and routes production to our vetted manufacturing partners. The work runs on CNC milling for hole patterns and pocket geometry, with surface grinding coordinated for flatness-critical mounting faces and reference datums. 5-axis CNC machining handles compound-angle adapter plate geometries when the design calls for it. Anodize, black-oxide, chemical conversion, and powder coat are handled by qualified finishers in the network — you get one routing and one inspection record.
Parts ship with routine tolerances to plus/minus .0002 inch on linear features and hole locations, with hole-pattern true position controlled by single-setup machining wherever the drawing allows. Surface grinding is coordinated for flatness-critical mounting faces and parallel datum schemes — the production network's grinders hold flatness and parallelism callouts that milling alone will not. Edge condition (radius, chamfer, deburr) is held to the drawing rather than to a generic shop standard, which matters on plates that sit against a gasket or a sealed face. Tight tolerance machining is the default class on adapter and faceplate work, not an upcharge.
Inspection is performed against the drawing on benchtop optical comparators, surface plates with indicators for flatness and parallelism, and calibrated hand gauging for hole pattern and feature locations. Every lot ships with a documented inspection record under our manufacturing partners' ISO 9001:2015 quality program. Anodize (Type II, Type III hard coat), chemical conversion (Alodine/chem-film), black-oxide, passivation, powder coat, and silk-screen / laser-mark labels are coordinated with qualified finishers in the network when the print calls for them — finish callouts ship complete, not as bare-metal parts with a finish line item open.

Plate work runs predominantly in aluminum CNC machining — 6061-T6 is the everyday choice for equipment mounting plates, faceplates, and optical adapter plates where weight and machinability matter, and 7075-T6 covers higher-strength aerospace and defense gusset and structural plate work. Stainless steel (304, 316) covers corrosion-service plates, marine equipment, and food-grade adapter work where aluminum cannot ship. Alloy steel handles load-carrying gusset plates and heavy structural adapters where weight is not a constraint. Engineering plastics (G-10, Delrin) ship on electrical isolation plates and optical adapter work where dielectric properties or thermal stability drive the choice.
Mounting plates, adapter plates, and faceplates ship into aerospace and defense structural programs, R&D and university optics groups, instrumentation OEMs, and any builder whose assembly depends on a precision-machined plate that lands flat and presents true datums to the components above. The shared requirement is a hole pattern that is right the first time, a face that is flat to print, and a finish that is complete when the part arrives.
