Martin Precision enhances measurement capabilities

Martin Precision Ltd, a supplier of precision-engineered components and assemblies for the aerospace and defence sectors, has strengthened its quality control processes with the integration of advanced metrology solutions from Bowers Group.

Supplying industry giants such as Rolls-Royce, Incora, Siemens, Farsound and Leonardo, Martin Precision invested in a suite of metrology tools, including Sylvac Scan 25T and Sylvac Scan F60T optical measuring machines, a Baty R14 profile projector and Bowers XT3 Holematic bore gauges, which have been a trusted solution in its operations for over a decade.

Alan Muir, quality manager at Martin Precision, says: “The Scan machines have proven to be reliable, user-friendly and highly accurate for the tolerances and sizes we work with. They have significantly improved our inspection efficiency, making them a valuable addition to our operations.”

The Sylvac Scan 25T and F60T optical measuring machine play a crucial role in final inspection, ensuring batch consistency and compliance with strict industry standards. Meanwhile, Bowers XT3 Holematic bore gauges are used throughout production and inspection testing to verify the internal dimensions of key components such as bolts, unions and small fasteners.

To enhance efficiency further, Martin Precision uses pre-programmed measurement routines at the final inspection stage, allowing for seamless batch processing and accurate digital recordkeeping. These records are vital for securing First Article Inspection Report (FAIR) approval and maintaining the company’s stringent quality assurance standards.

With the daily use of Sylvac Scan machines, Martin Precision has experienced significant improvements in accuracy, reliability and inspection speed. The company has successfully reduced inspection times, allowing for a more efficient workflow.

Arden Group reaches 60

The Arden Group, which was first launched by two brothers in the cellar of their family home, is celebrating its 60th anniversary. Brothers Frank and Philip Poynter first set up a die-making workshop with just one saw and a workbench in the 10 sq ft cellar of their mother’s semi-detached house in Bredbury, Stockport, in 1964. Today, the Arden Group comprises three specialist divisions: Arden Dies, Arden Engraving and Arden Software. Arden Dies says it has become the UK’s largest die-maker, manufacturing specialist dies and tooling for packaging and cartons.

High-volume machining of aircraft brake clips

Aerospace is Westley Engineering’s largest market, accounting for 45% of total production by value. A notable aerospace contract involves the manufacture of rotor clips used in aircraft disc brakes. Made from aerospace-grade steel and Inconel, the components see application in both civil and military aerospace programmes.

Three years ago, Westley Engineering improved the accuracy of the manufacturing process by switching from piercing holes in the clip using press tools to drilling them on a 40-taper vertical machining centre. Although it improved precision, the new approach also increased cycle times substantially and made the process more labour intensive. So in late 2023, the company installed a Brother Speedio S700Xd1 4-axis, 30-taper machining centre, followed by a second in April 2025. Supplied by Whitehouse Machine Tools, the exclusive UK and Ireland distributor for the Japanese manufacturer, these high-speed machines have now replaced the VMC for clip production.

In partnership with Whitehouse Machine Tools, Westley Engineering implemented an automated, single-operation process on each Speedio. The new production route features custom-built fixtures with nine inclined bars, each capable of holding 36 clips. This high-density arrangement enables over 300 parts to be machined per cycle, significantly more than the flat fixtures used previously.

Cycle times have been reduced to between two and three minutes per clip, depending on the variant. For example, the Inconel version requires additional milling on the outer arms, whereas the steel variants do not. Typical batch size ranges from 5,000 to 10,000 units.

Before deployment, the process was validated at Whitehouse Machine Tools’ Kenilworth technical centre.

£250,000 investment enhances quality control

Basildon-based Rodwell Powell, a specialist in precision machining for the aerospace, defence, marine, construction and other industries, has invested £250,000 in a renovation of its inspection department. The centrepiece of the upgrade was the acquisition of two CMMs manufactured by LK Metrology at its Castle Donington factory. The CMMs are delivering high levels of accuracy and efficiency to support increasingly complex quality control requirements for Rodwell Powell’s clients, which include Rolls-Royce Aerospace and Caterpillar.

The two next-generation LK Metrology Altera C CMMs are enabling the subcontractor to handle larger, more intricate parts with greater accuracy and efficiency. One of the new machines is an LK Altera C 10.7.5 equipped with a Renishaw PH10M Plus motorised indexing head deploying an SP25M probe with an SH25-2 stylus holder, which can perform scanning for form measurement and reverse engineering, as well as touch-trigger probing for accurate geometrical measurements. Featured also is a six-port stylus change rack to enable unattended completion of complex inspection routines.

The second CMM is a smaller LK Altera C 7.7.5 with PH10M Plus and SH25-2, and additionally equipped with a Renishaw TM25-20 touch-trigger probe module, allowing the continued use of legacy CMM Manager software alongside LK’s latest CAMIO 2024 R2. The latter is CAD-based metrology software that underpins the use of multiple sensors, intuitive programming, simulation, results analysis, GD&T, reporting and automation.

Andrew Rodwell, managing director, says: “Our investment in LK Metrology’s cutting-edge CMM technology is a game-changer for us. The CMMs allow for increased accuracy, greater throughput and reduced lead times, reinforcing our reputation for uncompromising quality in these highly demanding industries.”

David Brown Becomes SID President

During this year’s SID (Syndicat International du Décolletage) International Congress in Chicago, it was announced that David Brown, current president of the BTMA (British Turned Parts Manufacturers Association) and director at Neida (Stoke-based precision component supplier), will serve as SID president from 2025 to 2027.

SID was created in 1963 to bring together national organisations representing the precision machining industry. For over 10 years, Brown has been a member of the BTMA and, during his current presidency, has driven manufacturing initiatives related to skills and training, legislation and regulations, sustainability, and process improvements. During his new presidency at SID, Brown’s key objectives will take on a global focus.More information www.neida.co.uk
