Why Is Industry-Specific Knowledge Crucial For High-Quality CNC Machining Services?

CNC machining is no longer an off-the-shelf service. The paradigm shift from general machining to industry-specific machining is an inevitable trend as each industry has remarkably different demands for CNC machining services.

Industry	Core Standards	Key Materials	Core Requirements
Aerospace	AS9100	Titanium Alloy, 7075 Aluminum Alloy	Lightweight, heat-resistant, and fully traceable throughout the entire process
Medical-grade	ISO 13485	316 LVM Stainless Steel, Ti-6-4 ELI	Biocompatibility, ultra-high cleanliness
Automotive	IATF 16949	Carbon Steel, Aluminum Alloy	Batch production consistency, cost-effectiveness

These differences mean that suppliers lacking industry-specific knowledge are unable to meet customers' potential needs and provide CNC machining for industries services that meet industry standards.

For instance, an item that matches standard machining tolerance may not work in an aerospace environment because of poor traceability or may not work in a healthcare setting because of poor biocompatibility.

What Extreme Requirements Do CNC Machining Aerospace Parts Need To Meet?

CNC machining aerospace parts have very strict requirements. "AMS 6931:2004, Titanium Alloy Forgings - 6Al-4V ELI Annealed State," requires strict definitions for the machining requirements, chemical composition, and mechanical properties.

It becomes a necessity for machining vendors to have advanced cutting methods in their arsenal, in addition to a vast knowledge base for material properties. In this case, here are our responses:

Lightweight and High-Strength: Aerospace components demand materials that have a strong strength-to-weight ratio, and examples of these are titanium alloys and 7075 aluminum alloys. We apply topology optimization techniques in designing components that are lightweight yet strong.

High Temperature Resistance: The components like engines work in extreme temperatures. High temperature resistant material has been selected where extreme temperatures are a challenge.

Full Traceability: Every process step, from the procurement of materials through production, will be recorded. We can provide complete traceability reports for each batch of components.

Precision Heat Treatment: To make the aluminum alloys more resistant to stress corrosion, a critical aspect for aerospace applications, we apply T-73 heat treatment to the parts.

How To Ensure Biocompatibility And Ultra-High Cleanliness In Medical Device CNC Machining?

Medical device CNC machining has extremely high requirements for safety and hygiene, as these parts come into direct contact with the human body.

• Biocompatible materials: Only certified biocompatible materials like 316LVM biocompatible stainless steel and Ti-6AL-4V ELI biocompatible materials are used in our implants. This is an important feature since such materials do not react adversely with biotissue.

Successful Case: Five Axis Precision Machining Of Lightweight Titanium Alloy Fuselage Structural Components For Unmanned Aerial Vehicles

Client Challenge:

A leading industrial UAV manufacturer was faced with a critical challenge. They needed to produce a high strength and lightweight titanium alloy fuselage main frame. But the original supplier cannot meet both core requirements simultaneously:

Firstly, the curved surface had to be precise to an accuracy of ±0.05mm, while secondly, they had to be 15% lighter than before. In addition to this, deformation due to machining stress had to be avoided.

JS Precision Solution:

JS Precision, after analyzing their need, created a solution for them.

Our first project was working with a team of aerospace engineers to decompose the problem of precision and weight reduction based on AS9100 standards. We used specialized software to model stress distribution patterns according to different machining routes in an attempt to predict deformation during machining.

After that, a five-axis machining center was utilized for simulation and programming optimization so that all operations of feature machining could be performed in a single setup with less stress deformation. Meanwhile, specific cutting tools and optimized process parameters were adopted, with a topological weight-reducing structure that considered integrity.

Moreover, we have attempted to prevent the deformation possibility during the machining operation by pre-aging the material for the selected titanium alloy. Moreover, high accuracy inspection tools have been used throughout the process for monitoring the dimensions in real time for every step of the machining operation with ±0.05mm accuracy.

Results and Value:

This went beyond the expectations of the customer, as they witnessed an 18% reduction in the weight of the part, which was 3% over the expected target for reduced weight, and the strength was completely as expected, and the rate of compliance with dimension was 100%.

This allowed for an increase of almost 10% in the customer’s flight time of their drones and also led to JS Precision retaining the role of strategic supplier of core structural parts with the customer.

If you are facing such issues in machining aerospace parts, whether it’s dealing with precision in complex surfaces or working on lightweight designs, you can share such project experiences with us. We shall tap into this successful experience and merge it with the demands of the AS9100 standard to give you personalized solutions to successfully accomplish such CNC machining aerospace parts projects.
