About Us


Established in 1967, we are a family owned and run precision engineering company based in Aylesbury, Buckinghamshire. We consider ourselves to be one of the leaders in precision machining for a wide variety of industry sectors including Aerospace & Defence, Medical, Electronic, Analytical, Scientific and Motor Industries to name but a few.

We operate a policy of continual reinvestment in the latest machining technologies and this is only too apparent by taking a short look through our plant list which is available on this website. Our reputation is based on our ability to continually provide high quality machined components. This has made us the first choice for many companies requiring finished parts ready for assembly without the need for inspection. Our quality control systems operate in strict compliance with ISO9001 and Society of British Aerospace Companies standard AS9100, to provide our customers with total quality assurance. We have a dedicated full time inspection department with equipment kept exclusively for final inspections. Our equipment ranges from Coordinate Measuring Machines, Surface Testers, Shadow Graphs through to fully calibrated screw plug and ring gauges that are traceable to national standards. The company’s size is critical to its success. We are small enough to respond to individual requirements quickly, but large enough to provide a high level of technical support and quality control. Our companies aim is to provide our customers with 100% on-time deliveries and 100% quality assurance. CNF is able to offer scheduled despatch of kits or single components via kan-ban, direct to stock or direct to the assembly line. We aim to minimise supply chain logistics and handling costs in this manner. We would welcome the opportunity to quote on any machining requirements you may have either now or in the future. We aim to turn most quotations around within the same working day, however if we have to obtain prices from any of our long established third party supply network such as finishing or heat treatment companies, this may take a little longer. Should you have any further queries or questions you wish to discuss with us, we would be only too happy to hear from you. Should you wish a representative to visit you with samples this can be arranged at your convenience. We look forward to hearing from you in the not too distant future.   Neil C Fearnley – Director
