Four reasons two quotations for the same drawing disagree

None of these are machining costs. They are specification decisions, and they are why two suppliers can quote the same drawing 40% apart and both be right.

01

Two quotes on one drawing, 40% apart

One supplier priced a general-tolerance part and the other priced every dimension as if it were functional. Until the drawing says which dimensions carry the load, both prices are guesses about the same amount of inspection and rework.

02

Does the price arrive with a caveat attached?

A quotation that assumes the material, assumes the finish and assumes the quantity is not a price, it is an opening position. Those three assumptions are the ones that move the number when production starts.

03

The fixture cost that appears after you order

A dedicated fixture or tombstone is real work, and burying it in the piece price hides a decision from you. It belongs on its own line, where you can see whether the quantity justifies it.

04

How old is the price you are budgeting with?

Drawings move. A number quoted three revisions ago is a number for a different part, and the change was cheap when it was a two-minute note on a drawing and expensive after the program was cut.

How we quote

Three steps between your upload and a number you can budget with

A quotation is a manufacturing decision written down as a price, so we show the work behind it instead of sending a number on its own.

The review

An engineer prices the part, not a template

Someone has to read the drawing, decide which machine runs the part, check tool access and wall thickness, confirm the material is available and choose the inspection plan. That is the work that happens in the twelve hours.

Where the model and the drawing disagree, we ask rather than assume. A thread called M6 on the model and M8 on the drawing is a five-minute question now and a scrapped batch later, which is why it goes into the DFM note instead of into the price.

Everything that moves the price is on its own line

Machining, standard workholding, inspection and export packing sit in the machining price. Finishing, heat treatment, reports, assembly and expedited shipping are quoted separately, so you can decide which of them the project actually needs.

That also makes a second order predictable. The same part re-quoted later should land close to the first price, and where it does not, the difference is visible rather than buried.

  • 1
    Named material and finishThe grade and the surface treatment are written into the quotation, so a stocked alloy is not priced like a mill order.
  • 2
    Fixtures quoted, not hiddenA dedicated fixture appears as its own line when the quantity justifies it, and disappears into the piece price when it does not.
  • 3
    Nothing released before approvalThe price and the lead time are committed in writing, and production starts only after you approve them.

What happens when, after you upload

Within 12 hours you have the price, the lead time and the manufacturing notes together. If a drawing question changes the process, we ask before quoting rather than sending a number with a condition attached to it.

Approval is the only thing standing between the quotation and the machine. Production can start within 24 hours, and parts normally ship in 3–5 days on standard materials, with the finishing and inspection steps already scheduled inside that window.

What to upload

Files, and what each one is used for

Sending all five takes ten minutes and removes most of the questions that delay a quotation.

FileFormatWhat it decidesWhat happens without it
3D modelSTEP, STP, IGS, IGES, STL, X_TThe geometry that will be cut, and the CAM program built from itFree-form parts cannot be quoted accurately from views alone
2D drawingDWG, DXF, PDFTolerances, surface callouts, threads and datums, none of which a solid model carriesWe quote to general tolerance and ask before assuming anything functional
Material and finishWritten specificationCutting data, stock availability, and whether finishing is a separate operationQuoted as an allowance, which is less accurate than naming the grade
Quantity and required dateWrittenWhether the part runs one-up or on a dedicated fixture, and how it is scheduledQuoted one-off, which is rarely the cheapest way to buy five hundred
Marked functional dimensionsNote on the drawingWhich fits are inspected and reportedEverything is treated as nominal, which adds inspection time without adding value
What we quote

The quotation covers the whole route, not just the cut

One order can carry all of these, which is why the price and the lead time come from the same review.

12h

Instant quotation

Price and lead time returned within 12 hours of upload, written down rather than estimated over the phone.

DFM

Manufacturability review

Tool access, wall thickness, thread depth, tolerance and material availability checked before the part is priced.

1

Prototype quantities

A single part quoted on the same terms as a production run, with no setup fee that exists only because the quantity is small.

RUN

Production orders

The same program and the same quality system carry the release, from one part to runs of 10,000 or more.

FIN

Finishing coordination

Anodizing, plating, powder coating, heat treatment, bead blasting and marking, quoted as separate lines.

DOC

Inspection and documentation

100% inspection before shipment, with dimensional reports, first-article documents or material certificates on request.

Why GreatLight

What you get besides the number

The review is the part of a quotation that is worth more than the price. These are the commitments that come with it.

0

Charge for the engineering review

The DFM analysis is part of quoting rather than a separate service, and you are not committed to ordering anything.

12h

Hours to a priced answer

Price, lead time and manufacturing notes together within 12 hours, and production can start within 24 hours of approval.

Millimetres, stated up front

Our machining tolerance is quoted with the part rather than argued about after it, with ±0.0002 in as the imperial equivalent.

100%

Inspection before shipment

Raw material, in-process and final checks are recorded, and the report is available on request at the quotation stage.

FAQs

Quotation questions

What do you need from me for an accurate online CNC machining quotation?

A 3D model and a drawing with the functional dimensions marked, the material, any finish callout, the quantity you expect and the date you need the parts.

If you only have one of the two files, send what exists. We will say what is missing instead of filling the gap with an assumption.

How long does the quotation take?

Quotation and DFM analysis within 12 hours of upload. If the drawing raises a question that changes the process, we ask before quoting, because a price that arrives with a caveat attached costs more time than the question would have.

Is the DFM review really free?

Yes. It is part of quoting rather than a separate service, and you are not committed to ordering. Most of the value sits in the notes rather than the number: a radius that cannot be cut, a thread too close to a wall, a tolerance that will double the inspection time.

Will you sign an NDA?

Yes, and we can work under your template. Uploads are confidential by default, access is restricted to the engineers quoting the job, and information security is certified to ISO 27001:2022, which matters when the drawing is the valuable part of the project.

Can you quote from a 2D drawing only?

For simple prismatic parts, often yes, because the views define the geometry. Curved surfaces, blends and organic housings cannot be defined by views alone, so those need a model. Send the drawing and we will tell you which category it falls into.

What happens if the design changes after the quotation?

Send the updated file with the revision marker and we re-quote. Small changes usually come back within a few hours, and a change that affects fixturing or stock size is flagged before cutting.

Once production has started, a change becomes a new order, which is why the DFM step happens first.

Do you charge for a fixture or setup?

Standard workholding is part of the machining price. Where a part needs a dedicated fixture or tombstone, it is quoted as a separate line only when the quantity justifies it, so you can see what it costs rather than finding it buried in the piece price.

What is the minimum order quantity?

One part. Prototypes and production orders run on the same machines with the same inspection, so a single test article is a normal order, and the price you see is the price for that quantity.

Price, lead time and DFM notes in 12 hours

Upload the model and the drawing. The review costs nothing, there is no minimum order quantity, and nothing is released to production until you approve the price.
