Production Machining for Medical Device — FAQs
The questions engineering and procurement teams ask most often before a first quote.
What medical device components are well suited to Production Machining?
Production Machining suits documented repeat production with in-process inspection and predictable lead time. Typical medical device parts include Instrument bodies and handles, Handpiece and drive components, Diagnostic equipment housings, Fluidic and dispensing components.
What tolerances are typical for medical device production machining?
Northline holds ±0.001" as a typical envelope on Production Machining, with tighter callouts held on qualified features and reviewed against process capability during quoting.
Which medical device materials can Northline produce in volume?
Common medical device materials include Stainless 303 / 304 / 316 / 17-4 PH, Titanium Ti-6Al-4V, PEEK · Delrin · PTFE. Grade selection and heat/lot traceability are maintained; alternates are reviewed during quoting.
Can Northline provide inspection documentation for medical device programs?
Yes. Documented dimensional inspection, material lot traceability, and Certificate of Conformance are provided. Northline is ISO 9001:2015 certified and supports device-history documentation flowed down from customer quality systems.
Can you support both prototype and repeat medical device production?
Yes. The same setups used for prototype and first-article carry into repeat production, so geometry and inspection results carry forward without a process change.
How do you control medical device-specific engineering considerations on Production Machining?
Production-friendly geometry reviewed during quoting. Datum strategy, inspection frequency, and fixturing are reviewed during quoting against the specific medical device drawing requirements.
