ASG TGM in Preston enhances its aerospace manufacturing capabilities by doubling its size
A Preston-based firm has doubled its size through strategic investment, enhancing its aerospace manufacturing capabilities.
The move positions ASG TGM (Techni-Grind Machining) for future growth as it capitalises on new contracts and investment in advanced manufacturing technology.
The additional space is already being filled with investment in new 5 Axis CNC Machining.


What is 5 Axis CNC Machining?
5 Axis CNC Machining is an incredibly versatile machining process that implements subtractive machining technology, according to Get It Made Ltd.
Through this process, a workpiece is cut into shape using cutting tools working on five axes to deliver a final part.
CNC machining is incredibly popular due to its high accuracy, efficiency and repeatability.
The recent expansion by ASG Group supports the winning of a high-value Tier 1 aerospace contract
The contract involves the machining of large aerospace components up to 2.5 meters in length.
Currently, ASG TGM is managing eight different part numbers as part of this project, with the value of the orders exceeding £1 million annually.
The work is being executed in close collaboration with ASG Phoenix in Nottingham.
Simon Weston, Group Managing Director of ASG, stated the importance of this investment for the group's broader strategic objectives.


He said: “The expansion at ASG TGM is a key part of our growth strategy.
“By adding new capabilities and increasing our manufacturing footprint, we are not only meeting current demand but also strengthening our position for future opportunities.
“This is particularly important as we seek to deepen our role within the aerospace supply chain, where consistency, capacity, and precision are paramount.”
Central to this investment by parent ASG Group, is the acquisition of a new Mazak SDR machine, a £500,000 investment.
The new Mazak SDR machine is an advanced 5-axis machine and can handle components up to 3.8 meters, providing the precision required to support the highly specialised needs of the aerospace market.
Sarah Stephens, SG TGM Managing Director, said: “This expansion is about future-proofing our business.
“The additional capacity has allowed us to respond swiftly to new opportunities, including a significant contract with a major Tier 1 aerospace prime.
“This has given us the confidence to further invest in our capabilities, ensuring we remain a critical supplier to the aerospace sector.”
The firm’s ongoing investment into the latest CNC machinery has proved pivotal in helping the company secure crucial work for the UK rotorcraft industry.


Now, with the additional machining capacity in its new unit, ASG TGM is creating physical twinning of assets, offering increased production flexibility and greater operational resilience across the ASG Group.
“This investment allows us to better balance our capacity and meet the demanding requirements of the aerospace sector,” Stephens added.
“It’s a strategic step to ensure we are prepared not just for today’s contracts, but for future growth as well.”
“We’ve already brought on three new team members—a quality inspector, a CNC programmer, and an additional CNC operator—to support this growth.
“With plans for a further seven Mazak machines, we’re positioned to continue scaling our operations to meet demand for existing single-aisle structural rib work for wings.”
ASG TGM’s turnover is expected to exceed £5 million this year, with forecasts pointing to £8 million in 2025.
Despite this success, the firm faces challenges in recruiting skilled apprentices, a common issue across the manufacturing sector that is impacting companies’ ability to expand their workforce.
Stephens said: “Developing the next generation of talent is a priority for us, but it remains an uphill battle.
“There’s a need for greater support from the government and a shift in attitudes towards careers in manufacturing.
“Young people need to see the exciting, high-tech opportunities that exist in this field.”
