Aerospace CNC machining services demand the highest level of precision and repeatability possible. This is largely due to the fact that the aerospace industry upholds extremely strict requirements to ensure safety, performance, and reliability in state-of-the-art aviation and space flight applications.
However, consistent precision isn’t the only challenge that manufacturers face. Today’s aerospace parts often come with exceptionally complex designs. Machining these intricate shapes and part features while maintaining extremely close tolerances adds another dimension to the challenge. This is especially true in the case of small components, miniature parts and micro-machining, which often require advanced capabilities in CNC Swiss turning.
Additionally, the modern aerospace industry often uses difficult-to-machine materials such as exotic metals and engineering plastics. Generally, these are high-strength materials with very high levels of density, surface hardness, and other unique mechanical properties. Machining these materials accurately and repeatably demands an experienced aerospace manufacturing company that knows how to work with all of the latest metals and plastics in the industry.
Enter HyTech Spring and Machine – one of the American aerospace industry’s most capable CNC machining service providers since 1984. Backed by nearly four decades of experience, we are up for all the challenges that today’s aviation and space flight projects bring to the table.
The Key Challenges for Aerospace CNC Machining Services
Precision and Complexity:
Complex Part Geometries – Many aerospace parts are designed with intricate and complex shapes. Obviously, these are more challenging to machine accurately when compared to the simple custom machined parts. Our CNC machines need to handle 3D contouring, multi-axis machining, and intricate designs, while also being optimized for small parts and micromachining projects.
Close-Tolerance Precision – Aerospace components generally require very tight tolerances to ensure proper fit and function. Our CNC machines must be capable of producing parts with high precision, sometimes in the range of microns, to meet these requirements. Whether we’re CNC grinding aerospace springs with 0.002” diameters or Swiss turning complex cylindrical components with 7-axis geometries, HyTech maintains extremely high levels of accuracy and repeatability.
Exotic Metals and Composites – Modern aerospace components are often made from specialized metals like titanium, tungsten, and Inconel. Advanced engineering plastics and composites are also increasingly used. These materials are more challenging to machine due to their exceptional density, surface hardness, abrasiveness, and heat resistance. Specialized tooling and unique machining processes are often required to achieve the same level of precision and repeatability that we do with standard steel and aluminum materials.
Higher Standards in Aerospace Quality and Consistency:
Safety and Quality Standards – The aerospace industry is highly regulated and extremely strict on quality control. All CNC machining processes and materials must meet the required regulatory and documentation standards, such as AS9100:D, ISO 9001:2015, and NADCAP. This requires comprehensive quality control and documentation throughout the manufacturing process.
Traceability – There is an increased need for traceability throughout the modern aerospace manufacturing sector. Every custom machined part should be tracked from raw material to finished product to ensure quality and compliance with regulatory requirements. HyTech’s lean American manufacturing services are designed to facilitate better traceability and a streamlined supply chain.
