Diamond Turning at Symons
Diamond turning, or single point diamond turning as it is also known, had its origins in the aircraft industry. In the early 1930s came the development of the Rolls-Royce Merlin engine for the Supermarine Spitfire. To increase the performance of these engines it was necessary to maintain tighter tolerances and control surface finishes. Because of its unique hardness properties and wear resistance single crystal diamond tools were used for the first time.
The piston and rings account for up to 20% of the total frictional losses in an engine. By controlling the surface finish the engine’s performance can be increased.
Some of this work was carried out by Bryant Symons in Tottenham, London.
Diamond machining and special purpose diamond machine manufacture continued to be developed in Tottenham until December 1993 when Bryant Symons went into receivership.
In February 1994 Roger Winger and Graham Allberrey started Symons Mirror Technology. With their expertise in this field, and with the help of dedicated engineers, the company has gone from strength to strength.
Since the company’s inception its management and engineers have continually striven to drive diamond machining technology forward. To this end, in 2007 we purchased our new facility in Stevenage which gave us a fourfold increase in area. As a result we have been able to supplement our existing machining capability with the purchase of new machines and test equipment.
Over the past 20 years Symons Mirror Technology has been involved in some of the most successful projects completed by “blue chip companies” throughout the world.
