Three processes, six listed grades

Each cell is the tightest general tolerance the screen accepts before an engineer looks. Other grades and tighter features are welcome; they go to review.

Brass CW614N always needs an application and compliance review. Ranges are illustrative screening records, revision 2026-10-12-demo-2, not machine specifications.

3.0Part reports

Parts that arrived with open questions

Three sample jobs: what the request left open, and how the review settled it before anyone quoted.

An aluminium fixture block has four dowel holes and a broad milled step.

PR-01

25 fixture blocks, EN AW-6082-T6, 120 × 80 × 30 mm

Left open
The request gave the envelope and a general ±0.10 mm, but no pocket depth, datums or finish.
Settled
Both mills screened within. One reply listed the missing details, and the quotation followed the complete pack.
Illustrative multi-face machined aluminium housing.

PR-02

10 housings, EN AW-7075-T6, 140 × 120 × 80 mm

Left open
Some features needed ±0.02 mm, tighter than the 3-axis screening range, and the faces related to each other.
Settled
5-axis screened within. The review named the ±0.02 mm features and agreed the datum scheme before quoting.
Three turned brass bushings stand in a row with their bores and circumferential grooves visible.

PR-03

100 bushings, brass CW614N, Ø30 × 80 mm

Left open
Turning fitted the size, but brass always needs an application and compliance discussion.
Settled
The buyer stated the intended use and the evidence their product needs. Material review came first, then the quotation.

What buyers and engineers say

  • ★★★★★

    We sent a fixture plate with half the details missing. Milan came back the next morning with one list of questions, and the quote followed two days after we answered.

    Pieter H.Mechanical engineer, Veldhoven · March 2026

  • ★★★★★

    Our turned spacers moved here from a platform order. Same drawing, but Bas asked which diameter actually mattered, and the report covered exactly those features.

    Anouk B.Purchasing, Helmond · June 2026

  • ★★★★★

    Ten prototype housings in 7075 with related faces. The review call settled the datums before anyone quoted, which saved us a drawing revision.

    Daan M.R&D engineer, Eindhoven · August 2026

  • ★★★★☆

    A repeat batch of 200 brackets, started from the last approved record. Dispatch moved by two days; they told us a week ahead and the paperwork was complete.

4.0Process flow

From drawing to delivery

Each step has its own starting point, so nothing here adds up to a date. Your quotation confirms the dates.

  1. 4.1Send the RFQAny timeOne request with quantity, material, size, tolerance, finish and documents. Gaps are fine; mark them.
  2. 4.2First reply1–2 business daysMilan lists missing details in one reply, or confirms the request is complete.
  3. 4.3Written quotation2–3 business daysStarts after a complete RFQ pack. It names revision, scope, VAT, shipping and validity.
  4. 4.4Order and slotAgreed with youYour written order, the agreed revision, stock and a confirmed production slot.
  5. 4.5Machining3–6 weeksSetup, first-piece check, then the batch with the agreed in-process checks.
  6. 4.6External finish+1–2 weeks, if listedA separate allowance for agreed external finishing. Never added into a date.

7.0Quality documents

Agree what needs to be measured

Inspection starts with the drawing and the features you need checked. Every document is a request we confirm before quoting.

  1. 7.1EN 10204 3.1 material certificateMaterial evidence for the stock. It says nothing about finished dimensions.
  2. 7.2Dimensional reportMeasured values for the features you name, against the agreed drawing.
  3. 7.3First-article reportA full check of the first part before the batch runs, when the order needs one.
  4. 7.4REACH / RoHS evidence requestA request for evidence. Not a compliance certificate or end-use approval.
  5. 7.5Other documentName the document. We confirm scope and availability before quoting.

8.0Choosing a supplier

Local shop or platform?

Both have their place. Here is when each one is the better call.

An online platform

  • An instant price for a simple part from a STEP file
  • Large runs where the date can move
  • Comparing many suppliers in one place

Keelworks, in De Hurk

  • A drawing with open questions, and one person to settle them
  • Repeat batches that match the last approved revision
  • Inspection agreed feature by feature
  • A visit to see the first part measured, by agreement

Send one complete request
