Medical CNC Machining
Medical CNC Machining Services
Weldo supports medical-device companies and procurement engineers with drawing-based CNC machining, from functional prototypes and design improvements to repeat production. Send your files for material, tolerance, surface and inspection review.
*Final capability depends on material, geometry, feature size, workholding and inspection method.
Medical Manufacturing Requirements
Control Requirements Before Machining Begins
Functional interfaces, tolerance relationships, machining risks and service conditions are clarified before the production route is approved.
Functional Interfaces
Mating faces, threads, fluid paths, sealing features and assembly relationships are identified from the drawing.
Datum & Tolerance Scheme
Datums, GD&T, fits and critical feature relationships are checked for manufacturing and measurement access.
Machining Risk Review
Thin walls, deep cavities, small radii and burr-sensitive features are reviewed before the route is released.
Service Conditions
Cleaning, sterilization, chemical exposure and operating temperature are stated before material and finish approval.

Integrated Manufacturing Routes
Choose the Process Around the Drawing
The production route combines only the operations needed for geometry, material, finish and inspection.
3-, 4- and 5-Axis Milling
Multi-face geometry, pockets, bores and related features in fewer setups.
CNC Turning & Turn-Mill
Concentric diameters, grooves and threads with milled details where required.
Precision Grinding
Controlled size, geometry and roughness on critical contact surfaces.
Wire EDM
Fine slots and conductive-metal profiles with low mechanical cutting force.
Prototype Machining
Drawing-based functional parts for design verification before repeat production.
Surface Finishing
Specified surface condition, corrosion protection, appearance and cleanability.
Engineering Support for Medical-Device Innovation
Manufacturing feedback helps medical-device teams improve manufacturability while preserving the drawing’s functional and regulatory intent.
DFM & Risk Review
Identify fragile walls, inaccessible features, tolerance conflicts and finish allowances before material is cut.
Controlled Design Iteration
Machine revision-controlled prototypes, inspect critical features and return practical feedback for the next design release.
Production Transfer
Carry the approved revision, tooling, workholding and inspection plan into low-volume and repeat orders.
Material Selection
Materials for Medical Components
Choose the exact grade from mechanical load, cleaning or sterilization method, chemical exposure, traceability and device documentation.
| Material Family | Common Grades | Typical Applications |
|---|---|---|
| Stainless Steel | 304, 316 / 316L, 17-4 PH | Instrument parts, fluid components, housings and corrosion-resistant interfaces. |
| Titanium | Grade 2, Grade 5 and drawing-specified grades | Lightweight, corrosion-resistant parts after grade and documentation review. |
| Aluminum | 6061, 6082, 7075 | Equipment housings, brackets, fixtures, heat sinks and lightweight structures. |
| PEEK | Virgin, glass-filled, carbon-filled and specified medical grades | High-performance insulators, guides, fixtures and fluid-system components. |
| POM / Acetal | POM-C, POM-H and approved special grades | Low-friction guides, fixtures, rollers, spacers and non-implant components. |
| PTFE & PA | Virgin or specified filled grades | Seals, insulators, bushings and low-friction parts after service review. |
Material grade, condition, certification and substitution rules are confirmed against the drawing before production.
Surface Protection
Finishes for Medical Parts
Select the finish from substrate compatibility, corrosion, cleanability, appearance, dimensional allowance and service environment.
Machined Finish
Controlled tool marks and drawing-specified roughness for functional features.
Mechanical Polishing
A smoother stainless-steel surface for appearance, handling and cleaning.
Passivation
Restores corrosion resistance on compatible stainless steels after fabrication.
Anodizing
Protective oxide finish for compatible aluminum or titanium specifications.
Medical Project Assurance
Quality Controls That Support Reliable Sourcing
Drawing review, documented inspection and controlled production help reduce sourcing risk from prototype approval through repeat orders.
Medical-industry procurement engineers can define material traceability, drawing revision, inspection records, packaging and delivery requirements before releasing the purchase order.
ISO 9001 Quality System
Documented procedures support consistent drawing-based production and inspection.
- ISO 9001:2015 certified
- Drawing and revision control
- Calibration and inspection procedures
Project Quality Documentation
Required records are defined before quotation and prepared to the agreed format.
- Dimensional inspection reports
- Material certificates when specified
- First-article and finish records on request
Manufacturing, Inspection & Delivery Control
Multi-axis CNC machining, EDM, CNC grinding, injection molding, 3D printing and sheet metal support prototypes through standardized batch production.
- Experience with 100+ metal and plastic materials
- CMM and calibrated dimensional inspection
- Final review, delivery control and protective packing
ISO 13485, FDA registration, implant approval or other medical-specific certification is not implied. State every regulatory, biocompatibility, cleanliness and documentation requirement on the RFQ for confirmation.
Medical CNC Machining FAQ
Plan Your Medical Project
Can an alternative material be used for an early prototype?
Only with written approval. The quotation identifies any substitution and whether the prototype is suitable for fit, function or process validation.
How is dimensional stability managed when machining medical polymers?
Stock condition, moisture, clamping force, cutting heat and measurement temperature are controlled for the selected polymer and geometry.
How are sterilization and chemical exposure considered?
State the cleaning method, sterilization cycle and chemical exposure so material, finish and dimensional effects can be reviewed.
How are burr-sensitive edges and internal features controlled?
Edge limits, deburring access and prohibited rounding are reviewed before the machining and finishing route is approved.
What happens if the drawing changes after the order is placed?
The new revision is reviewed for material, tooling, inspection, cost and schedule impact before production continues.
