Machined hardware for instruments, optics and vacuum.

Optical sub-plates, mount bodies, stage plates, detector housings and chamber plates, machined to three published tolerance classes. Engineered once to one inspection plan, so every reorder is the same part — with a dimensional report on every order.

Rendered black-anodized optical sub-plateAn isometric render of a black-anodized aluminum optical sub-plate: a grid of tapped holes across its face, counterbored mounting holes at its corners, tapped holes in one edge and a precision pocket with tapped holes in its floor. Callouts: flatness held per tolerance class, 0.002 inch per inch at Precision; a tapped hole grid, threads to class 2B or 6H; black anodize, Type II, on the standard menu.OPTICAL SUB-PLATE · 6061-T6 · REV AXYZ1231Flatness held per classPrecision: 0.002 in/in2Tapped hole gridThreads to class 2B / 6H3Black anodizeType II black, standard menu

What ships with every order.

  • 01

    Material certs

    Certs for the material lot your parts were cut from.

  • 02

    Dimensional report

    Measured against the job’s inspection plan and reported against your nominals and tolerances.

  • 03

    First article on request

    FAI in AS9102 format when your program calls for it.

  • 04

    Full traceability

    Each part traces to its packet revision, shop, machine and material lot.

Three tolerance classes, published and priced.

  • Mixed callouts are normal. Each feature is priced at the class it needs — usually less than holding the whole part to the tightest one.
  • GD&T is welcome. Tight-class work and position or profile callouts beyond Precision are reviewed by an engineer within four business hours.
  • Tight-class work runs only at shops with a CMM on site.
