Life Science CNC Machining Services
Custom metal and engineering-plastic components for diagnostic instruments, laboratory automation, fluid-handling systems, medical equipment and bioprocess hardware—from functional prototypes to repeat B2B production.
What is life science CNC machining?
Life science CNC machining is the manufacture of drawing-controlled mechanical parts used in laboratory, diagnostic, medical and bioprocess equipment. CNC milling, turning, EDM and fabrication create instrument frames, manifolds, housings, carriers, sensor mounts, motion components and test fixtures from production-grade metals and engineering plastics. A successful plan controls functional datums, sealing interfaces, fluid paths, alignment, burrs, surface condition and documentation—not only the nominal outside shape.
Why life science hardware needs a dedicated machining plan
Life science assemblies can combine precision motion, optics, sensors, fluid handling and repeated cleaning. We translate the customer drawing and risk priorities into a practical manufacturing and inspection route.
- Sample and fluid paths: ports, bores, threads, grooves and manifold intersections need clear dimensions, edge requirements and inspection access.
- Sensor and optical alignment: mounting datums, bores and mating faces must preserve the customer-defined relationship between mechanical, electronic and optical elements.
- Sealing interfaces: O-ring grooves, gasket lands and cover faces require coordinated geometry, flatness, surface condition and finish allowance.
- Motion and automation: shafts, carriers, nests and actuator mounts need repeatable position, wear control and assembly clearance.
- Cleanability and handling: recesses, burrs, exposed threads and cosmetic surfaces should be reviewed around the customer’s cleaning, packaging and end-use process.

Life science design details to define before quoting
| Design area | What to specify | Why it matters |
|---|---|---|
| Functional datums and alignment | Primary datums, position, runout, flatness and relationships between sensors, optics, motion or mating components. | Prevents independent feature control from missing the assembly’s real functional relationship. |
| Fluid paths and manifold ports | Bore size, intersection, thread, edge break, dead-volume concern, surface condition and test scope. | Tool access, burr removal and inspection planning depend on the complete internal geometry. |
| Sealing interfaces | O-ring groove standard, gasket compression, land flatness, surface finish and coating restrictions. | Machining and finishing must work together to preserve the customer-designed seal. |
| Thin walls and deep pockets | Minimum wall, allowable distortion, corner radius, depth, cosmetic face and free-state inspection condition. | Workholding and material-removal sequence can influence stability and appearance. |
| Threads and inserts | Thread class, engagement, insert type, pull-out requirement, locking method and protected areas. | Supports reliable assembly and prevents finish or cleaning operations from damaging interfaces. |
| Cleanability and crevices | Customer cleaning method, inaccessible recesses, sharp internal corners, exposed threads and acceptable residue. | Allows DFM review around geometry and handling without assuming a validated sanitary or sterile process. |
| Burrs and particles | Edge-break limits, prohibited burr locations, fluid-contact intersections and visual acceptance criteria. | Burr removal must protect dimensions, surfaces and small passages. |
| Finish thickness and masking | Finish type, thickness, color, cosmetic class, sealing lands, bores, threads and dimensions controlled after coating. | Surface treatment can change fit, appearance, friction and sealing performance. |
Finishes planned around fit, cleaning and appearance
Passivation and electropolishing
Customer-specified passivation or electropolishing may be coordinated for suitable stainless components. State the governing specification and required documentation in the RFQ.
Anodizing
Aluminum anodizing supports corrosion protection, wear resistance and color coding. Type, thickness and masking should be defined.
Bead blasting
Bead blasting can create a uniform matte appearance before anodizing or as a customer-approved finish.
Powder coating
Powder coating services provide durable coverage for frames, guards and enclosures; precision interfaces normally require masking.
Polishing and brushing
Customer-defined polishing or brushing can address appearance and selected surface requirements. Specify direction, roughness or approved sample where relevant.
As-machined and protected zones
Functional faces can remain as-machined. Clearly identify fluid-contact areas, sealing lands, optical interfaces, threads, bores and cosmetic surfaces.
Inspection planned around functional risk and revision control
The drawing, revision, material, finish and acceptance requirements become the basis for manufacturing and inspection. High-risk features can receive first-article and in-process checks before final release.
- Contract review of drawing, revision, model, material, finish and quantity
- First-article inspection when requested for setup or process validation
- In-process checks on critical and drift-sensitive features
- Final dimensional and visual inspection
