Turkish Medical Equipment Service Provider × Honscn DFM-Driven CNC Machining of Medical-Grade SUS316 Precision Components
Client & Project Overview
Our client is a professional medical equipment service and maintenance provider based in Turkey, specializing in the repair and refurbishment of various medical devices used in hospitals and clinical laboratories.
Unlike original equipment manufacturers, maintenance companies often face a unique challenge: critical replacement components are needed, but original drawings are missing or incomplete. In many cases, they only have worn-out parts or approximate measurements.
For this project, the client approached us with basic dimensions and application details for several components used in medical equipment. Instead of simply machining parts from incomplete information, we worked closely with the client using a DFM (Design for Manufacturing) approach, helping convert their initial idea into fully manufacturable engineering designs.
Product Overview: Medical Device Precision Adjustment Components
-
Product Type: Core transmission and adjustment components for medical devices
-
Material: SUS316 medical-grade stainless steel
-
Manufacturing Process: CNC Swiss-type automatic machining
-
Key Features:
-
Precision internal threads
-
Stepped positioning shafts
-
Anti-slip knurled knobs
-
These parts are used in precision adjustment and transmission mechanisms inside medical instruments, where smooth operation and accurate positioning are essential.
SUS316 stainless steel was selected due to its excellent corrosion resistance and ability to withstand repeated high-temperature sterilization, making it widely used in medical environments.
Key Challenges
1. Incomplete Drawings and Design Conversion
Challenge:
Because the client specializes in equipment repair rather than manufacturing, they did not have complete engineering drawings. Most of the information came from rough measurements and worn original components.
Without detailed technical documentation, directly entering production would have been risky.
Our Solution:
Our engineering team carefully analyzed the provided data and created complete engineering drawings for each component.
This process included:
-
Defining dimensional tolerances (±0.01 mm)
-
Determining optimal thread specifications
-
Setting surface roughness standards
-
Ensuring proper assembly compatibility
The finalized drawings were reviewed and approved by the customer before production began.
2. Machining SUS316 Stainless Steel with High Precision
Challenge:
SUS316 stainless steel is well known for its corrosion resistance, but it is also tough to machine. The material tends to work-harden quickly, which can affect dimensional consistency—especially when producing small parts with precise threads and stepped shafts.
Maintaining consistency across large production quantities required careful process control.
Our Solution:
We used CNC Swiss-type automatic lathes, which are ideal for machining small precision parts in the 10–20 mm size range.
With this method:
-
All machining operations were completed in a single setup
-
Coaxiality and dimensional consistency were maintained
-
Smooth fit and assembly performance were achieved
The final components demonstrated the smooth insertion and alignment required for medical device adjustment mechanisms.
3. Moving Directly from Design Approval to Mass Production
Challenge:
In the medical industry, testing cycles can be long, and customers typically prefer to start with small pilot orders. In this case, however, the client chose to move directly to large-scale production after design confirmation.
Each product variant was ordered in 1,000 pieces, which required absolute confidence in both the design and manufacturing process.
Our Solution:
Before starting production, we performed:
-
3D assembly simulations to verify compatibility
-
Detailed internal engineering reviews
-
Process planning based on our previous experience in medical component manufacturing
These steps allowed us to identify and eliminate potential interference or assembly issues before production began.
Manufacturing Process
The final manufacturing workflow included:
-
Engineering design and DFM optimization
-
CAD drawing creation and customer approval
-
CNC Swiss-type precision machining
-
Knurling and thread finishing
-
Dimensional inspection and quality verification
This structured process ensured stable quality across all production batches.
Project Results & Customer Feedback
After the designs were finalized and production completed, the components met all performance expectations.
Results
-
Excellent dimensional consistency across all batches
-
Smooth and precise assembly performance
-
Reliable corrosion resistance suitable for medical environments
The customer expressed strong confidence in both the engineering support and manufacturing quality.
Customer Feedback
After reviewing the technical drawings and prototype performance, the client shared:
“Many suppliers can only machine parts based on drawings. You helped us complete the drawings themselves. After seeing the professional designs and the performance of the samples, I was completely confident. Let’s proceed with 1,000 pieces for each model.”
