Locating Hole Accuracy
Dowel pin holes and locating holes control repeatability in fixtures.
Hole position is checked relative to datums, not only as separate dimensions.
What We Solve
Common Challenges in Automation Fixture Machining
Automation fixture parts control position and repeatability. A small machining error can create assembly drift, inspection error or unstable machine operation.

◇
Datum Face Flatness
Fixture plates and nests can create error if mating faces are not controlled.
Flatness, parallelism and mating faces are reviewed before quotation.

⚡
Replacement Part Fit
Machine builders often need one replacement part to fit an existing assembly.
Drawing revision, old part photos and assembly notes are collected before machining.

Small Batch Acceptance
Large factories may reject small fixture orders or urgent spare parts.
XHR supports prototype and low-volume fixture components from drawings.
Why These Problems Happen
Most CNC machining problems are not caused by one dimension alone. They come from unclear function, missing datum notes, unsuitable tolerance choices, material behavior, finishing sequence or inspection gaps.
Locating Hole Accuracy
Dowel pin holes and locating holes control repeatability in fixtures. This issue usually appears when drawings do not separate cosmetic dimensions from functional dimensions, or when process risk is not reviewed before quoting.

How XHR Prevents Them Before Production
Before machining starts, XHR reviews the drawing like a production risk map: which features affect assembly, which features affect appearance, and which features need inspection proof.
Locating Hole Accuracy
Hole position is checked relative to datums, not only as separate dimensions. XHR also reviews drawing notes, tolerance stack-up, material condition, finish sequence and inspection method before confirming production details.

RFQ Checklist for This Type of Part
Clear RFQ information helps avoid quote delays and prevents misunderstandings after production starts.
- Send a 3D model and a 2D drawing with material, tolerance and finish notes.
- Mark functional dimensions, datums, fitted surfaces, threads and inspection-critical areas.
- Tell us prototype quantity, expected repeat quantity and delivery destination.
- Share assembly purpose or failure history if the part is replacing an existing component.
- Confirm whether you need material certificates, inspection reports or photos before shipment.
How XHR Reduces RFQ Risk
We review drawings, material, critical dimensions, surface finish, inspection focus and delivery requirements before quoting. The goal is to reduce avoidable surprises before parts enter production.
