CNC Technology boosts oil and gas capacity with DN Solutions Puma GT 3100

The recent investment by CNC Technology in a DN Solutions Puma GT 3100 lathe highlights a critical shift in the UK subcontract engineering sector, driven by rising demand for high-precision components in the oil and gas industry. This surge in demand for corrosion monitoring equipment, particularly from Middle Eastern markets, underscores the industry's need for reliable, high-performance machinery capable of handling challenging materials like Inconel alloys and superalloys. For engineers and manufacturers, this means a renewed focus on efficiency and adaptability in production processes. The ability to swiftly scale up from small batches to larger volumes without compromising on quality or lead times is becoming increasingly essential.

Steve Littlehales, Managing Director at CNC Technology, emphasised the urgency of their investment, stating that the existing capacity was insufficient to meet the sudden increase in demand without affecting other customers. This situation is a clear signal to UK engineers that flexibility and scalability in production are paramount. The Puma GT 3100, with its robust design and advanced features, offers a solution that not only addresses immediate needs but also future-proofs the company's capabilities. The machine's high-torque spindle and advanced control system enable faster cycle times and improved productivity, which are crucial in a market where precision and speed are equally important.

The decision to invest in a more powerful lathe rather than another Lynx model reflects a broader trend towards specialised machinery that can handle complex tasks with greater efficiency. This shift is particularly relevant for engineers who are often required to balance the demands of diverse projects with the need for consistent quality. As CNC Technology demonstrates, the right machinery can significantly enhance a company's ability to meet customer expectations while maintaining profitability. For UK engineers, this case underscores the importance of strategic investment in technology that aligns with market trends and future requirements.

CNC Technology, a precision engineering subcontract specialist based in the West Midlands, has expanded its turning capacity by investing in a new DN Solutions Puma GT 3100 two-axis, box guideway lathe from Mills CNC. This investment was prompted by a significant increase in demand from a long-standing oil and gas customer for high-precision machined components used in corrosion monitoring equipment. The new lathe, installed in January 2025 at CNC Technology's facility in Cradley Heath, has been specifically selected to handle the demanding requirements of machining complex parts from difficult materials such as Inconel alloys and superalloys.

The Puma GT 3100 is equipped with a 22kW/2,800rpm high-torque spindle, a 12-station servo-driven turret, and a live-centre (MT5) tailstock. It also features the advanced Fanuc 0iTP control with a 15” iHMI touchscreen. Additional options include a parts catcher with a conveyor, an auto tool setter, and a FilterMist extraction unit. The machine offers a substantial turning length of 790mm and a turning diameter of 525mm, making it well-suited for the large batch sizes now required by CNC Technology's customer. The increased capacity is necessary to meet the new order, which calls for batch sizes of 300-off components, a significant jump from the previous one- and two-off quantities.

The decision to invest in the Puma GT 3100 was driven by the need to balance the demands of increased production without compromising on quality or delivery times for other customers. Steve Littlehales, Managing Director at CNC Technology, explained that the company's existing turning capacity would have struggled to handle the sudden increase in volume without affecting lead times. The Puma GT 3100's robust design and high-torque spindle allow for faster speeds and feeds, as well as more aggressive depths of cut, which have improved part cycle times and overall productivity. This has enabled CNC Technology to efficiently meet the new demand while maintaining well-engineered standards.

Mills CNC, the exclusive distributor of DN Solutions and Zayer machine tools in the UK and Ireland, has been a key partner in this process. CNC Technology had previously invested in a Doosan Lynx 220LM from Mills CNC in 2013 and was impressed with the machine's performance and Mills CNC's service and support. This existing relationship, along with the technical specifications, cost, and availability of the Puma GT 3100, influenced the decision to choose Mills CNC as the supplier for the new lathe.

The Puma GT 3100 is not only meeting the immediate needs of CNC Technology but also positioning the company for future growth. The machine's flexibility and performance make it capable of handling a wide range of jobs for both new and existing customers. As Steve Littlehales noted, the investment in the Puma GT 3100 is a strategic move that ensures CNC Technology remains competitive in the precision engineering sector.

Mills CNC continues to support CNC Technology with pre- and after-sales services, reinforcing the strong partnership between the two companies. This collaboration highlights the importance of reliable machine tool suppliers in helping manufacturers adapt to changing market demands and maintain their competitive edge.
