A trusted partner

With close to three decades of industry experience, Perfect Bore Manufacturing Ltd. is a leading UK manufacturer, specialising in honing, super-finishing, gun-drilling and tooling services

Founded in 1988 specialising in honing and super-finishing, Perfect Bore Manufacturing Ltd. quickly expanded its services to include gun-drilling capabilities following two years of rapid growth. By 1994 the business had relocated to a larger facility, while further investment allowed the company to develop manufacturing cylinder liners and pistons predominantly for high-end performance motorsport markets. Following a period of continued growth Perfect Bore was sold to the US conglomerate, Dover Corporation Inc in 2001, while the company’s gun drilling and honing engineering division reverted to private ownership through an acquisition by one of the division’s former owners during 2004.

Over the proceeding years Perfect Bore continued expand through heavy investment into its machinery, management infrastructure and employees, leading to an increase in its manufacturing footprint from 6000 sq ft to 32,000 sq ft. This investment has enabled the company meet the increasing demands of its customers to provide additional services, including preparatory turning operations, boring and honing of billets up to 300 mm diameter and three metres in length. Perfect Bore has operated a fully documented quality system since 1994 and is fully AS9100/ISO 9001:2008 approved and a SC21 bronze signatory. The company was accepted as a partner within the Fit for Nuclear programme during December 2015 and is today is committed to providing the aerospace, defence, power generation (including nuclear) and oil and gas markets with bore solutions for highly critical parts.

The aerospace market represents an important market for Perfect Bore, where the company provides bore solutions for major OEMs with approvals from clients including Airbus, BAe, Goodrich Actuation Systems, Boeing, Moog and Rolls Royce; supporting projects including B787 Dreamliner, A400M and A350. Indeed, in the field of major aerospace component manufacturers, Perfect Bore’s name is renowned for quality and on-time delivery, while continual investment gives its customers the confidence to off-load components that have critical geometric ID and OD requirements. “There is currently a strong market for the construction of aircraft and we have recently seen a return of demand to the UK from low-cost manufacturing environments, because UK manufacturers are valued for their quality and as a reliable source for long-term support across the total lifetime of supplied components,” reveals Perfect Bore Manufacturing Managing Director, Jason Wyles. “We offer a honest and reliable service where both quality and on-time delivery to the client is paramount. We also provide service at a price that we feel adds real value to the overall supply chain.”

Perfect Bore continuously invests into research and development to maintain its high levels of quality and products support across all of the industry sectors that it serves. The company invests heavily in the development of its 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. For example, during November 2015 Perfect Bore completed a £1 million investment into a new CNC/Prismatic Drilling division, which allows it to drill multiple holes in various shaped blocks and offset holes in round billets. These machines can provide cost effective solutions to drilling holes in mould tools for high-end automotive applications, manifolds for oil and gas tool applications and plates for nuclear fabrications.

The company has also recently launched a dedicated CNC Cylindrical Grinding Division to complement its bore producing services as the largest sub-contract supplier in the UK, providing:

  • A fully managed and supported Sub- Contract division
  • High specification CNC cylindrical grinding
  • Fully temperature controlled environment equipped with Studer grinding machines
  • State-of-the-art measuring equipment including a Mitutoyo Laser Scan Micrometer, RA120
  • Roundness Tester and 2D Colour Vision System
  • Improved logistical management and reduction in manufacturing lead time for parts that require honing and match grinding

While Perfect Bore services a host of industry sectors, it is thought that the aerospace sector will be particularly interested in the development of this new facility. The company produces bore solutions for a number of projects within the aviation market, on components including piston rods; cylinders; actuator bodies and housings; actuator pistons and sleeves; tail rotor actuators; spools, valves, guides and blocks; hinges; strut pistons and cylinders; cargo door pistons, cylinders and retraction pistons. With dedicated managers for each division, Perfect Bore prides itself on providing first class service and support.

By providing a comprehensive in-house service, Perfect Bore is able to afford its clients the highest levels of quality and a trusted lifetime support service. Although the company has been highly successful within the aviation sector in recent years, it will increasingly look to expand its operations within the energy and nuclear sectors over the coming months. “Over the next 12 months we will also be looking at returning opportunities within the oil and gas tool sector. We will also be looking to explore opportunities within the nuclear industry in both new build and decommissioning applications,” Jason concludes. “We are fully onboard with the Fit for Nuclear programme and are endeavouring to seek partnerships wherever possible and would look forward for the opportunity to proving services for clients that require a trusted supplier that has the approvals to cement a strong relationship.”
