Claro Precision Engineering started out as a tool making company in Harrogate back in 1978. As time went by and we began to accumulate experience and expertise, we took on precision machining and soon decided to concentrate our efforts on subcontract machining of precision machined parts. Five years later, we moved into a first class facility in Knaresborough – We then began to specialise in key areas such as lasers, medical instrumentation, aerospace, subsea, and electronics housings. It is this organic growth and naturally acquired expertise that makes Claro a reliable choice of partner when it comes to precision machining. Below is a list of just some of the services that we provide. If you would like further information on any of them, or if you would like to discuss your own requirements, please don’t hesitate to contact us directly. Our professional and helpful staff really know what they’re talking about, so give us a call today!

Case Study 1 – The Suture Cutter

Please head over to our website to view our case studies. Case Study 1 features a project we were approached with to manufacture a Suture Cutter. This cutter was needed to cut Magnum wire suture cleanly and with ease. We worked closely with Arthrocare’s design team to develop and manufacture an innovative method of achieving consistently clean cutting. We are now working with Arthrocare to reduce batch production costs while maintaining the same high standards of cutting, look and feel at the same time.

Case Study 2 - The Turntable Deck

Case Study 2 features a project we undertook for a client who approached us with a concept for a top of the range turntable deck. We were asked to help develop the concept and produce full manufacturing drawings and models. Upon completion of the prototype, we carried out a design review which enabled us to evaluate the design and develop it further. Please visit our website to read this case study in full and to find out more about our services. If you would like to discuss your project requirements, please call us today at Claro Precision Engineering Ltd and we will be happy to help.
