ABS CNC Machining Service
ABS is considered for rigid housings, fixtures and prototype parts. Stock shape grade, colour, additives and environmental exposure should be confirmed before machining.

When ABS fits — and when to pause.
Housings and covers
Useful when impact, weight and appearance matter.
Prototype parts
Machined stock can validate geometry before a molded route.
Chemical or outdoor exposure
Confirm compatibility and weathering grade rather than assuming general ABS performance.
Use a complete material designation.
The following examples are common ways buyers describe the family. They are not a stock list and they do not authorise substitution.
- Unfilled machinable ABS stockConfirm supplier grade, condition, stock form and required documentation.
- Flame-retardant or modified ABS only by named supplier gradeConfirm supplier grade, condition, stock form and required documentation.
RFQ material line
ABS · ABS resin or stock grade and colour · stock form · quantity · required certificates · permitted substitutions.
If an application approval matters, name the regulation, edition and acceptance evidence.
Plan machining around the material behaviour.
Heat and chip control
Avoid local heating and smeared edges.
Thin walls
Review clamping and unsupported features.
Bonded assemblies
Define adhesive and joint requirements before finishing.
Specify the final surface and dimensions.
As-machined
Set tool-mark and edge expectations.
Vapour or solvent processes
Require grade-specific compatibility and controlled acceptance.
Painting
Confirm preparation, adhesion and colour requirements.
Separate material identity from dimensional inspection.
Purchase specification, supplier documents, lot traceability and an agreed identification or test method where appropriate.
Drawing, datums, critical characteristics, inspection conditions and the required report format.
Use the relevant tester only when the drawing defines the parameter, method, location and acceptance range.

ABS machining questions.
How should ABS be specified for machining?
State the complete ABS resin or stock grade and colour, the stock form, permitted substitutions and required documents. Add the drawing, quantity, finish and inspection requirements.
Does a listed grade mean it is stocked?
No. The examples help structure an RFQ. Availability, substitutions, price and delivery are confirmed for the project.
How are tolerances confirmed?
Tolerances depend on geometry, material condition, feature size, quantity, finishing and inspection conditions. Mark critical dimensions and datums; the quote confirms what can be held.
Can material documents and inspection reports be supplied?
State the required certificate, traceability and dimensional or test report with the RFQ. The available document set and test method are confirmed before production.
Bring the drawing and material into one review.
Send the CAD model or drawing, quantity, material designation, service conditions, finish and acceptance requirements.
