CNC Machining

Micro Machining Service

For small parts, tiny bores, narrow grooves, thin walls, and precision features where tooling, fixturing, and inspection matter just as much as cutting.

Overview

Built for tiny features and critical dimensions

Micro machining depends heavily on workholding, tool selection, heat control, and inspection. At quote time we review the smallest tool diameter, aspect ratio, tolerance stack-up, and fixturing needs.

Tiny Features

Micro holes, narrow slots, sharp corners, and thin walls.

Critical Tolerances

Focus on the dimensions that drive fit, function, and assembly.

Engineering Review

We identify chip clearance, fixturing, burr control, and tool access early.

Short Runs

Good for samples, pilots, lab hardware, and precision components.

Materials

Common materials

Material selection has a big effect on burrs, tool wear, distortion, and final surface finish. If the part is critical, share the intended application and key dimensions.

Applications

Where micro machining is used

Medical Devices

Small precision parts, fluid pieces, and laboratory hardware.

Electronics

Connectors, thermal parts, probe fixtures, and alignment hardware.

Aerospace

Lightweight brackets, sensor bodies, and precision connectors.

Robotics

Miniature mechanisms, end-effectors, and motion subassemblies.

Inspection

Inspection and quality control

Inspection for tiny parts can be just as difficult as machining. Mark your key dimensions, functional faces, and reference datums so we can choose the right inspection method.

Design Notes

What helps the quote and build

Keep non-critical tolerances flexible

Reserve the strictest tolerances for only the dimensions that truly drive function.

Avoid extreme depth-to-width ratios

Deep narrow features increase tool deflection and breakage risk.

Provide clear datums

Good datums reduce setup ambiguity and help with inspection planning.

Note burr expectations

Edge condition matters in tiny parts and can affect both fit and appearance.

FAQ

Frequently asked questions

Do I need a 2D drawing?

It helps a lot. The 3D model defines geometry, while the drawing can define critical tolerances, datums, and finish requirements.

What increases machining difficulty the most?

Very small holes, deep narrow grooves, thin walls, hard materials, and strict tolerance requirements all add cost and risk.

Can you quote a sample quantity?

Yes. Small sample quantities are often the best way to validate geometry before moving into a larger run.
