Perfect Bore works with major OEMs and sub-tier companies operating in market sectors including the aerospace, oil & gas, nuclear, scientific instruments/medical, automotive and power generation industries. Bore solutions supplied by Perfect Bore can be found in components manufactured by major OEMs such as Airbus, BAe, Goodrich Actuation Systems, Boeing, Moog and Rolls Royce; supporting projects including B787 Dreamliner, A400M and A350.
These industries require the production of bores in components to extreme tolerances and in some cases to sub-micro geometrical tolerances combined with specific surface finish requirements. It also offers Research & Development for one-off prototypes and a dedicated manufacturing facility to produce high-quality parts to exacting tolerances. The company has worked to ensure that their name is renowned for quality and on-time delivery, with ‘just-in-time’ schedules forming a regular part of the production and the development of its processes through lean manufacturing initiatives also enables the company to offer cost-effective solutions to its clients.
Perfect Bore operates a fully accredited integrated management system that is compliant to AS9100:2016, ISO 14001:2015 and BS 18001:2007. It is a bronze awarded signatory to SC21 and is also a signatory to both Fit For Nuclear (F4N) and the NDA’s Supply Chain Charter for Nuclear Decommissioning Sites.
Andover-based Perfect Bore was formed in 1988 specialising in honing and superfinishing. Following two years of rapid growth, it expanded into gun drilling and consolidated its position in the market by acquisition in 1993, before moving to larger premises in 1994.
Further investment led to Perfect Bore manufacturing cylinder liners and pistons predominantly for high-end performance Motorsport markets. Following continued growth, Perfect Bore was sold in 2001 to the Dover Corporation Inc, a US Conglomerate. In February 2004 the gundrilling and honing engineering division reverted to private ownership when it was acquired by one of its former owners. Since 2004 the company has acquired all the units on Sterling Park and it now operates out of a fully secured industrial estate with a manufacturing footprint of 32,000 square feet.
Perfect Bore Manufacturing Ltd invests heavily in the development of machining capabilities and continually undertakes pure research on new techniques around its core deep hole processing services. Along with the intention of stretching achievable boundaries, it allows the company to offer true value for money to its customers, with reduced cutting times enabling parts to be manufactured to an acceptable budget.
PBML’s technical engineers have extensive experience in international markets and keep themselves up to date with advances in tooling, exploiting years of embedded knowledge to fully utilise the latest deep hole boring techniques. Adapted machinery contributes to making the machining of parts quicker, easier, and in some cases, possible.
