خدمة تصنيع ماكينات CNC المصنوعة من مادة PMMA (الأكريليك)

Machined acrylic — the transparent polymer selected where glass would otherwise be used, cut to the tolerance, minimum wall and lead time the shop holds.

What we hold on PMMA (acrylic)

Six numbers a buyer asks for before sending a drawing. Everything here is
already published on this page — nothing is extrapolated.

$Where PMMA (acrylic) sits against the other 22 materials
اقرأ هذا أولاً. Process, maximum part size and lead time are
identical on all 23 material pages — they describe the shop, not the material. They sit
here as a one-line constant instead of taking a column each in a nine-column table, which
is how they were published before. The three that genuinely change material by material
are tolerance, minimum wall and price band. This page publishes no grade list -
the table it replaces has no grade or subtype column either — so there is no matrix
section below; name the grade you want on the drawing instead.

S3 · Which polymer?

Four questions, then a material

This page used to answer none of these. Each card points at a page that
already exists on this site — written before this redesign, and previously linked from
nowhere on this page.

هل يحتاج إلى أن يكون واضحا؟
Two transparent polymers are published here — this page and polycarbonate. The two pages are the comparison.

Is the part going to be hit?
PC takes that question and is the toughness page here; acrylic is the optical one. Both are published, so compare the two.

Does the surface have to come out flawless?
Polishing and bead blasting are the two finishing pages linked from this page; both have their own process notes.

Is the part really flat sheet?
Then the cutting pages are the ones to look at rather than this one — laser cutting and waterjet both have pages here.

S4 · Machining & tolerance

What governs the part you get

The published tolerance on this page is Not lower than  ±0.25 mm (±0.010"),
on the drawing, to ISO 2768. Where a feature needs better than that, say so on the
drawing — that conversation belongs before the tool goes in, not after.

S5 · Finishes

Finishing an acrylic part

This is the polymer set of finishes: polishing, blasting, sanding and fine machining. The metal pages list the plating and heat-treatment routes instead.

S8 · FAQ

7 questions PMMA (acrylic) buyers actually ask

Every answer traceable: published figures from this page, published pages
from this site. No new claims.

Which grade of acrylic can you machine?
This page publishes no grade list, and the At a Glance table it replaces has no grade or subtype column either — so no grade is named here. That is a limit on what is listed, not on what is quoted: name the grade or the property you need on the drawing and it is confirmed in writing.
What tolerance can you hold?
±0.25 mm, on the drawing, to ISO 2768 — the figure published on this page. Where a feature needs tighter than that, mark it on the drawing so it is priced and inspected as a controlled feature.
What is the smallest wall and the largest part?
Minimum wall is 0.80 mm. Maximum envelope is 200 × 80 × 100 cm. Both are shop-wide constants, identical on all 23 material pages.
How fast is a PMMA (acrylic) part?
3 to 10 days, with complex parts at the far end. Post-processing, if you ask for it, is a separate step and adds to that window.
Which finish should I ask for?
The cards in the finishes section above are the polymer set — تلميع, تفجير حبة و as-machined / deburring among them. The full list of 20 is at التشطيبات السطحية.
ما هي الملفات التي يجب عليّ إرسالها؟
STEP, STP, IGES, IGS, SLDPRT, STL, DXF, DWG, PDF, DOCX, JPG, JPEG, PNG or ZIP. A 2D PDF plus the model is the combination that gets quoted fastest.
هل سيتم الحفاظ على سرية رسوماتي؟
Uploads stay with the people quoting and making the part. If you need a mutual NDA in place first, say so on نموذج الاتصال and it is arranged before files change hands.

الخطوة التالية

Send the drawing — we come back with the material call and the price

Upload the model and the 2D PDF. You get a manufacturability note, a note on the resin if the drawing leaves it open, and a price.
