Precision CNC Components for Medical Machinery
Medical machinery components often require a combination of complex geometry, dimensional consistency, smooth surfaces and reliable assembly interfaces.
Unlike conventional CNC parts, medical equipment components may contain multiple precision features within a compact structure. These can include internal bores, stepped diameters, threaded holes, cross holes, mounting interfaces, grooves and complex contours.
Our MAZAK turn-mill machining capability allows multiple machining operations to be integrated into a controlled production process, reducing unnecessary setups and helping maintain positional accuracy between related features.
For more complex geometries, 5-axis simultaneous machining can be used to access multiple surfaces while minimizing repeated clamping.
Why This Type of Medical Part Is Difficult to Machine
1. Multiple Precision Features
A single component may combine:
- Precision turning diameters
- Internal bores
- Threaded holes
- Cross holes
- Mounting holes
- Deep grooves
- Complex contours
- Thin-wall structures
Maintaining dimensional relationships between these features is more difficult than machining a simple turned component.
2. Multi-Surface Machining
Medical machinery components frequently require machining on several faces.
Traditional multiple-fixture machining can introduce accumulated positioning errors.
With MAZAK turn-mill and 5-axis machining, multiple surfaces can be processed with fewer setups, improving feature-to-feature consistency.
3. Small Features and Tight Tolerances
Small holes, internal threads, narrow grooves and precision bores require careful tool selection, cutting parameters and process control.
The machining strategy is adjusted according to:
Material → Geometry → Tool → Cutting Parameters → Fixturing → Inspection
4. Surface Quality
Components used in medical machinery often require clean, burr-free surfaces and controlled surface roughness.
Special attention is given to:
- Toolpath optimization
- Cutting-edge condition
- Feed rate
- Tool wear
- Deburring
- Final inspection
MAZAK Turn-Mill Machining Process
Our machining strategy is designed around the actual geometry of each custom component.
Turning
Precision turning is used for:
- OD / ID machining
- Stepped diameters
- Cylindrical surfaces
- Threads
- Grooves
- Precision bores
Milling
Milling operations handle:
- Slots
- Flats
- Mounting surfaces
- Pocket features
- Cross holes
- Complex contours
5-Axis Machining
For complicated medical components, 5-axis machining helps access multiple surfaces and complex angles while reducing repeated repositioning.
This is particularly useful for components with:
Complex contours + angled features + multiple mounting interfaces + difficult-to-reach surfaces.
Integrated Turn-Mill Machining
The combination of turning and milling in one machining system allows rotary and milling features to be coordinated within the same manufacturing strategy.
This helps reduce:
Multiple setups → positioning variation → accumulated machining errors.

Frequently Asked Questions
Q1: Do you manufacture standard medical parts?
We mainly focus on custom CNC medical machinery components rather than standard catalog parts. Customers can provide drawings or 3D CAD files, and our engineers develop the machining process based on the actual component requirements.
Q2: Can you machine both aluminum and stainless steel?
Yes. Common options include 6061 and 7075 aluminum alloys, 304 and 316L stainless steel. Other materials can also be evaluated according to the application.
Q3: Can MAZAK machines perform both turning and milling?
Yes. MAZAK turn-mill equipment is designed to integrate turning and milling operations, making it suitable for components containing both cylindrical and milled features.
