Feature scale and access
Small holes, fine slots, narrow pockets, small threads, feature depth, end forms, corner radius intent, and tool access directions should be called out clearly.
Micromachining services
Micromachining, planned around feature scale, access, edge condition, and inspection intent.
Small holes, fine slots, thin walls, miniature turned or prismatic features, and handling-sensitive parts require more than a scaled-down model. Share feature sizes and depths, datums, access, breakthrough condition, supported geometry, edge and burr requirements, material condition, and inspection intent so the request can be organized and a project path confirmed before acceptance.
- Model and enlarged detail views
- Small-feature and datum review
- Scope confirmed per quote
Capability review
This page describes common request types. Available processes, equipment, tolerances, inspection, documentation, and fulfillment are confirmed for each quote.
Overview
Small features become easier to review when function and measurability are explicit.
At a small scale, a feature cannot be reviewed only by how it looks in a model. A useful request identifies the functional datums, feature size and depth, access direction, thin or unsupported geometry, breakthrough and edge condition, material and starting form, handling sensitivity, feature relationships, and how each critical requirement will be accepted.
Edges, walls, and breakthrough
Thin or unsupported geometry, allowed contact zones, breakthrough surfaces, burr intent, edge condition, and protected features belong in the request.
Inspection planned with the requirement
Critical features, datum references, measurement conditions, visual criteria, sampling intent, and documentation needs should be stated before an inspection method is confirmed.
Fulfillment review
Requests are reviewed manually. The fulfillment route and availability are confirmed before acceptance.

Micromachining feature review
What should the small-feature drawing explain?
Select a review feature to see the details that help clarify the request.
Hole size, depth, breakthrough, and datum intent
A small-hole request should define where the feature begins and ends, what controls its location, and how the entry, exit, and edge condition affect function.
- Diameter, depth, through or blind condition, and intended function
- Access direction, datum location, spacing, and adjacent geometry
- Entry, breakthrough, edge condition, burr intent, and inspection method
Helpful drawing detail
Use a section view when needed and identify the hole location, total depth, breakthrough surface, edge intent, and measurement reference.
Process fit, equipment fit, achievable requirements, inspection, fulfillment, and timing are confirmed from the project information during quote review.

Quote workflow
From small-feature context to a confirmed project path.
A short, human-managed review keeps scale, access, delicate geometry, edges, inspection intent, and open questions visible before work is accepted.
- 01
Share the part and scale
Upload the model, drawing, enlarged detail and section views, photos with scale, material information, quantity, mating context, and known functional requirements.
- 02
Review the small-feature drivers
Feature size and depth, datums, relationships, access, support, breakthrough surfaces, edge and burr intent, handling sensitivity, finish, measurement condition, and acceptance criteria are organized for follow-up.
- 03
Confirm the path
Process fit, equipment fit, achievable tolerances, inspection method and scope, fulfillment, timing, and remaining questions are resolved before acceptance.
- 04
Coordinate the project
Approved files and requirements become the reference point for project communication and requirement control.
Request readiness
Small decisions that make micromachining requests easier to review.
Clear feature and acceptance intent is more useful than assuming a method or applying the same requirement to every surface.
Design intent before assumptions
- 01
Pair the model with enlarged requirement views.
Use the model for shape and add drawing detail or section views for small-feature dimensions, datums, tolerances, depths, edge conditions, finishes, revisions, and inspection intent.
- 02
Define datums and feature-to-feature relationships.
Show which faces, bores, diameters, edges, or holes locate the part and connect each critical feature, pattern, fit, and interface to the references that control function and acceptance.
- 03
Fully define each small hole and cross-feature.
State the size, depth, through or blind condition, breakthrough surface, entrance and exit edge requirements, spacing, orientation, datum reference, mating function, and inspection intent.
- 04
Fully define slots, pockets, thin walls, and access.
State widths, depths, end forms, corner radius or other corner conditions, wall or tab thickness, unsupported length, support and contact zones, protected surfaces, and every required tool access direction.
- 05
State edge, burr, surface, cleanliness, and handling intent.
Identify intersections and breakthrough edges that matter, permitted edge break or rounding, protected features, finish areas, visual criteria, contamination sensitivity, and handling or presentation requirements.
- 06
Make inspection and acceptance requirements explicit.
Identify critical characteristics, datum references, measurement condition, required coverage or sampling, visual criteria, acceptance record, and documentation needs without assuming a particular measurement method.

FAQ
Micromachining quote questions.
A STEP or STP model and matching PDF drawing are a strong starting pair. Include enlarged detail or section views for the small features, plus material and condition, quantity, functional datums, mating context, feature sizes and depths, access, breakthrough condition, edge and burr intent, finish, handling sensitivity, inspection or documentation needs, and target timing when known.
Miniature plates, brackets, inserts, pins, sleeves, bushings, small holes and cross-features, fine slots, grooves, narrow pockets, thin walls, tabs, ribs, small threads, and other delicate-feature requests may be submitted. Process fit, equipment fit, achievable requirements, inspection method, fulfillment, and availability are confirmed from the project information.
For holes, state size, depth, through or blind condition, breakthrough surface, edge requirements, spacing, orientation, and datum reference. For slots and pockets, state width, depth, length, end form, corner conditions, and mating intent. For thin walls, tabs, or ribs, state thickness, height, unsupported length, support and contact zones, protected surfaces, access, and function.
Identify the entrances, exits, intersections, tips, and protected surfaces that matter. State any permitted edge break or rounding, visual acceptance intent, contamination sensitivity, handling needs, and features that must retain a defined edge rather than using a general note alone.
Tie each critical requirement to its functional datum and acceptance intent, then state the measurement condition, required coverage or sampling, visual criteria, acceptance record, and documentation needs. Equipment fit, achievable tolerances, measurement method, inspection scope, and availability are confirmed during quote review.
Requests are reviewed manually. The fulfillment route and availability are confirmed before acceptance.
