Custom CNC Machining for Precision Parts
±0.0002" tolerances · < 10 days lead time · 46 materials
CNC machining is a subtractive process where computer-controlled tools remove material from a solid block to produce precision CNC parts with tight tolerances and controlled surface finishes. MakerStage supports CNC milling services, CNC turning services, andSwiss-type turning for prototype and production parts in metals and engineering plastics.

Types of CNC Parts We Machine
CNC machining is the right fit for custom CNC parts that need repeatable geometry, tighter tolerances, or production materials that 3D printing cannot match. Typical examples include housings, brackets, manifolds, shafts, threaded components, and inspection fixtures in aluminum, steel, titanium, brass, copper, and engineering plastics.
Housings, plates, and brackets
Flat or prismatic CNC parts such as actuator housings, mounting plates, heat sinks, and structural brackets benefit from 3-axis or 5-axis milling and straightforward inspection.
Shafts, bushings, and manifolds
Turned and milled machine parts such as spacers, bushings, threaded shafts, and fluid manifolds are a good fit when concentricity, thread quality, and surface finish matter.
Fixtures, end-use parts, and spares
Production-ready CNC parts include jigs, nests, tooling plates, sensor mounts, and replacement components where material traceability and dimensional repeatability matter more than raw print speed.
Milling, turning, and Swiss-type CNC machining
Custom CNC machining is not one process. A milled housing, a turned shaft, and a Swiss-turned pin each need different machine setups, inspection plans, and cost drivers. Matching the part to the right CNC process helps control tolerance, lead time, and quote accuracy.
CNC milling services
3-axis and 5-axis CNC milling for housings, plates, brackets, heat sinks, fixtures, and other prismatic parts that need controlled flatness, hole locations, and surface finish.
CNC turning services
CNC turning for shafts, spacers, bushings, threaded features, and round parts where concentricity, diameter control, and consistent surface finish drive fit.
Swiss-type turning
Swiss-type turning for small cylindrical parts, pins, sleeves, and high-aspect-ratio features where guide-bushing support improves stability during machining.
Prototype and production CNC parts
Custom CNC machining services for one-off prototypes, pilot builds, and production runs where material selection, inspection level, and revision control matter.
What to include for a cleaner CNC quote
A complete RFQ package lets the shop estimate setup time, fixture needs, inspection effort, and material sourcing before production starts.
- 3D CAD file: STEP, IGES, or native CAD when available
- 2D drawing for critical tolerances, threads, and datums
- Material grade, quantity, finish, and inspection needs
Need help preparing a CNC RFQ?
Use the RFQ checklist before uploading files so material, finish, tolerance, and inspection requirements are clear at the start of quoting.
3-Axis vs 5-Axis Machining
Choose the right machining approach for your project. Multi-axis equipment can handle both standard and complex geometries, with feature-specific tolerances as tight as ±0.0005 in. (±0.013 mm) on qualified 5-axis setups.
