Precision device prototyping for MedTech and Defence.

McMahon Micro Machining specialises in the rapid prototyping and manufacture of precision mechanical and micro-mechanical devices for medical technology and defence applications.

We work on projects where tolerances matter, failure is not acceptable, and confidentiality is assumed. Our focus is on small, complex, tolerance-critical parts and assemblies that demand careful engineering judgement rather than volume production.

All machining, fitting, inspection, and prototype assembly is performed in-house, allowing close control over quality, fast iteration during development, and secure handling of sensitive programs.

Our focus and approach.

Our work sits at the intersection of precision engineering, regulated technology, and high-consequence device development. We support engineers and organisations developing early-stage and pre-commercial devices, recognising that many of the core challenges in MedTech and Defence — such as tolerance stack-up, materials behaviour, and functional reliability — are technically equivalent.

We prioritise engineering correctness over throughput, working closely with clients to refine, test, and validate precision devices before scale-up or transfer to production environments.

Industry engagement.

McMahon Micro Machining is an active participant in Australia’s advanced manufacturing ecosystem and maintains memberships with industry bodies aligned to its MedTech and Defence focus, including the Medical Technology Association of Australia (MTAA), AusBiotech, and the Defence Teaming Centre (South Australia).

These affiliations reflect ongoing engagement in sectors where precision, traceability, regulatory awareness, and professional integrity are essential for process engineering and complicated device design and manufacture.

McMahon Micro Machining has a well equipped Adelaide, South Australia based micro engineering facility specialising in small volume mechanical and electro mechanical prototyping, assembly and testing. All carried out in-house at our Tonsley Innovation District workshop and Adelaide University Mawson Lakes, South Australia teaming up with the Australian National Fabrication Facility recourses. Stainless steel, titanium, aluminium and brass small parts machined. Mechanical and electro/mechanical devices assembled and tested. Prototype development. Process engineering advice. Bringing manufacturing back to South Australia.

Our micro-machining work in most cases do not allow us to publish photos or our work. We are asked often, "Why don't you showcase on your website parts you have made, micro device development work or post photos on socials? People would love to see them".

To answer this, small precision-manufacturing companies like ours do not publish case studies, cannot disclose which defence programs we support or medical companies we consult with. We by default only provide general descriptions of our capabilities. This is why advanced micro parts and device experts like McMahon Micro Machining only use broad industry terms like "defence", "aerospace", "government"' and "medical devices". If we were given express permission, we would happily share our work.

Our core consulting and engineering business works by default with, and not limited to -

• NDAs
• Secrecy provisions
• Non-disclosure related to clients (Primes, Government, Aerospace, Med-tech, etc.)
• Restrictions around imagery, components, testing, and supply chain details.

McMahon Micro Machining is an Adelaide-based precision engineering firm providing in-house rapid prototyping, micro-machining, and precision assembly services for medical device development and defence-aligned engineering programs.

McMahon Micro Machining specialises in: Tolerance-critical mechanical and micro-mechanical components Precision device sub-assemblies and prototype mechanisms Iterative prototype development under NDA and IP constraints Low-volume, high-accuracy manufacture where repeatability and inspection are critical All machining, inspection, and assembly activities are conducted internally to support fast design iteration, dimensional control, and secure project handling. McMahon Micro Machining operates across both MedTech and Defence domains, applying the same precision methodologies, quality controls, and engineering discipline required in regulated and high-consequence environments.

The company is a member of the Medical Technology Association of Australia (MTAA), AusBiotech, and the Defence Teaming Centre, reflecting active participation in Australia’s medical technology, defence, and advanced manufacturing sectors.

Precision milling machines, lathes and diamond micron lapping and polishing equipment. Ultrasonic and mechanical cleaning equipment. The advantage of the combined Tonsley and Mawson Lakes workshops gives us a range of machines from rapid prototyping on manual machines to precision repeatable parts manufacture on the Robodrill, Willemin-Macodel 8 axis or DMG Mori precision mills. Device troubleshooting and rapid small volume custom parts manufacture. Olympus OLS 5100 laser measuring microscope for final quality control and surface quality testing, QMS, QC. Our own small device pressure test equipment and electronic diagnostic test machinery. Richard McMahon as a certified master watchmaker has the ability to design, machine and assemble micro machinery himself, this is a huge advantage in vertical integration. Keeping tight control of the prototype and manufacture process from start to finish. We can identify issues and quickly adapt design and manufacture changes in hours, not weeks or months. Our own fabrication and prototyping facility and partnering with Adelaide University and the University of South Australia at Mawson Lakes South Australia. McMahon Micro Machining do NOT outsource our machining or parts design overseas as many of our local Adelaide competitors fail to disclose. We work with our clients to source as many materials, and component elements we can use in the prototype development chain as possible.

Prototype design, manufacture, quality control and testing.

McMahon Micro Machining facilities include clean assembly spaces for complicated small machinery and instruments. All in secure spaces in the Tonsley Innovation District, South Australia and Future Industries Institute at Mawson Lakes, South Australia. CAD using Autocad Inventor and Fusion in-house. Precision assembly work carried out in our environmentally controlled micro-engineering workspaces. Complicated machinery assembled by qualified and certified horologists and watchmakers. We have access to clean rooms for assembly at both our Tonsley and Mawson Lakes machining centres for device assembly. Decades of experience manufacturing precision parts for the medical and defence industries. We have a network of advisors and experts in many engineering and design disciplines. We have a proven track record of designing, prototyping and testing devices for our clients in IVF, cardiology and ophthalmology disciplines. Members of AusBiotech biomedical organisation. We work closely with our clients offering quick modifications to our components and devices made by us, in-house. Our client feedback shows our strength is speed and communication. Keeping costs low by using a vertically integrated lab and workshop like ours can save months in development and many thousands of dollars. We have the capability to work on multiple devices in parallel to fast track testing and evaluation. ISO 9001 quality management system being implemented. We specialise in proof of concept, high quality working devices for venture capital demonstration meetings, potentially enabling access to funding quicker than other methods. Once a device is functioning, certification processes can be carried out. This is how many successful companies work today and is an advantage in the fast moving medical and tech industries.
