PEEK Machined Parts: Inspection Plan and Report Checklist

Agree what happens when a measurement is outside its limit: segregation, recheck, buyer notification and controlled disposition. Keep reworked parts identifiable until they pass the agreed reinspection. A supplier should not erase the history by reporting only the last acceptable measurement.

Link material identity, part number, revision and batch reference to the report. Retain sample results with the approval record so receiving inspection uses the same interpretation. For functional, pressure or electrical testing, explicitly define responsibility and confirm availability instead of treating dimensional inspection as a substitute.

Material review: unfilled, glass-filled and carbon-filled PEEK have distinct properties and must not be interchanged without engineering approval. State the agreed designation and required evidence in the purchase specification. Where service performance depends on the material, the design authority must confirm suitability rather than delegating that decision to a generic machining quotation.

Geometry review: focus on thin sections, fibre direction in reinforced stock, bore relationships and the volume of costly stock removed. Inspection should address dimensions after an agreed stabilisation period and temperature, with traceable grade identification and controlled contact force. Resolve any feature outside the confirmed measurement scope before ordering, and use the same drawing interpretation for the sample, production report and receiving checks.

Delivery protection: clean individual bags or separators and protection against scratches or mixing of similar-looking grades. Identify the part and revision on the delivered batch. Damage, a material mix-up or an unclear report can prevent an otherwise dimensionally acceptable part from entering the assembly.

For a review of peek machined parts, include compound designation, operating environment, load, temperature, traceability needs and dimensional acceptance conditions. Upload a dimensioned PDF with its revision and a matching STEP or IGES model when available. Add sample and batch quantities, required documents and the delivery destination so the offer can separate technical scope from logistics.

Precision Machining India holds ISO 9001:2015 and uses LMW, Jyoti and Ace Micromatics turning centres, a 3-axis Ace Micromatics FANUC VMC and Mitutoyo inspection instruments. This does not imply AS9100, ISO 13485 or 5-axis capability. Any additional process or specialised test must be reviewed and confirmed separately. Request an NDA before sharing confidential drawings when needed, then use the quotation form to begin the part-specific discussion.
