How it works

From quote package to finished machined parts

SSI moves each job through review, programming, setup, machining, inspection, and delivery so the quoting inputs become a practical production plan.

  1. Quote

    Review the part

    SSI reviews the print, CAD file, sample part, or repair context so the open questions are clear before setup.

  2. Plan

    Program and fixture the work

    CAM, tooling, and workholding are matched to part geometry, tolerance stack, material behavior, access, and repeat-run expectations.

  3. Machine

    Mill or turn the parts

    CNC milling and turning are run with practical setup discipline for one-offs, short runs, repair work, and repeat production components.

  4. Verify

    Inspect and deliver

    Critical features are checked against the drawing, with inspection records, material traceability, or first-article documentation added when scoped.

CNC scope

CNC machining scope and quote details

These are the details that turn a machining request into a reliable quote and a repeatable production plan.

Materials
Aluminum, carbon steel, stainless steel, tool steels, industrial plastics, and other machinable materials by request.
Quantity and program
Quantity, setup time, material availability, machining time, inspection records, delivery timing, and repeat-order needs.
Drawing and CAD files
STEP, IGES, SolidWorks, or PDF prints with critical tolerances, finish requirements, revision level, and due date.
Fixtures and workholding
Custom workholding can be scoped when the part requires repeatability, accurate location, efficient handling, or future repeat runs.
Inspection records
In-process checks, final inspection, material traceability, first-article documentation, and other records are added when required.
Work paths

Match the CNC quote path to the type of work.

The same shop can handle very different machining needs, but the quote package changes depending on whether the work starts from a print, a worn sample, or a repeat production requirement.

01

New part from print or CAD

Best when a drawing, model, tolerance callout, material, finish, and delivery target are available before quoting.

  • Prototype and one-off components
  • Short-run parts with defined inspection needs
  • Revision-controlled prints and CAD files
02

Repair, replacement, or rework

Best when the current part, worn features, fit requirement, and functional risk can be documented before machining starts.

  • Photos, sample parts, or measurements
  • Critical dimensions and mating features
  • Material and surface-condition expectations
03

Short run or repeat production

Best when setup, fixtures, inspection frequency, packaging, and reorder expectations need to be stable across multiple batches.

  • Production fixtures and workholding
  • First article or documented inspection
  • Repeat order planning and revision control

Shop proof

CNC work is quoted from the real setup, not only the print.

Part geometry, access, workholding, material behavior, inspection records, and repeat-run expectations all affect how a job moves through the shop.

CNC quote questions

Common CNC machining questions

Send prints or CAD files, material, quantity, tolerance, finish, due date, delivery needs, and any photos or sample parts for repair or rework jobs. Call out critical features and inspection-documentation requirements early.

Send the part requirements SSI needs to price the job.

Attach the drawing, CAD file, photos, or sample context SSI should price from.
