Cogsdill-Nuneaton boosts efficiency with Mills CNC DNX 2100SB mill-turn machine

Cogsdill-Nuneaton's adoption of Mills CNC's DNX 2100SB marks a pivotal shift in their machining operations, driven by the need to enhance efficiency and meet rising demand. This investment is not merely about upgrading equipment; it's about future-proofing the company's production capabilities. The DNX 2100SB, with its advanced features like the 18.5kW milling head and 60-tool ATC, allows for complex parts to be machined in a single setup, significantly reducing downtime and labour costs. The addition of automated systems, such as the Hydrafeed bar feeder and Renishaw probing solutions, underscores a move towards lights-out manufacturing, a crucial step in maintaining competitiveness in the UK market.

The decision to invest in this technology is a direct response to the audit findings, which highlighted bottlenecks and inefficiencies in their turning operations. By replacing older, less reliable CNC lathes with the DNX 2100SB, Cogsdill-Nuneaton is addressing these issues head-on, ensuring they can meet increasing demand without compromising on quality or delivery times. This strategic move also reflects a broader trend in UK manufacturing, where companies are increasingly turning to automation and multi-tasking machines to streamline processes and remain agile in a competitive landscape.

For UK engineers, this development signals a growing emphasis on integrating advanced machining technologies to enhance productivity and operational efficiency. As more companies follow suit, the demand for skilled operators who can harness these technologies will rise, making expertise in multi-tasking and automation a valuable asset. The takeaway for engineers is clear: embracing these advancements is essential for staying relevant and competitive in the evolving manufacturing sector.

Mills CNC has recently supplied Cogsdill-Nuneaton with a new DNX 2100SB multi-tasking mill-turn machine, marking a significant enhancement to the company's turning operations. This investment serves as a cornerstone in Cogsdill-Nuneaton's strategy to overhaul its machining processes, boost operational efficiency, and enable lights-out, unattended production. The DNX 2100SB, which Mills CNC introduced to the UK and Irish markets in late 2025, is designed for machining complex, high-precision parts in a single setup.

The DNX 2100SB is equipped with a 10" chuck/81mm bar capacity main spindle and an 8" chuck sub-spindle. It features an 18.5kW/12,000rpm B-axis milling head with a +/- 120-degree rotary/tilting range and 0.0001-degree indexing capabilities. The machine also includes a 60-tool-position ATC and the advanced Fanuc 0iTP control system. The model supplied to Cogsdill-Nuneaton was further enhanced with a Hydrafeed (MultiFeed 80) short magazine bar feeder for continuous automated production, a Hydrafeed 'Rota-Rack' rotary parts accumulator for safe part handling, a Renishaw RMP 60QE compact spindle probe for automated inspection, and a Renishaw HPMA tool-setting and broken tool detection system.

Installed in December 2025, this DNX 2100SB is the first of its kind in the UK or Ireland, reflecting Cogsdill-Nuneaton's commitment to staying at the forefront of manufacturing technology. The company, known for its precision tooling solutions, has a long-standing relationship with Mills CNC, having previously invested in Doosan machines distributed by Mills. This history of positive experiences, coupled with Mills' industry-established support, influenced Cogsdill-Nuneaton's decision to purchase the DNX 2100SB.

Cogsdill-Nuneaton's investment in the DNX 2100SB was driven by the need to address inefficiencies identified during a mid-2025 audit of their turning operations. The audit highlighted issues such as an over-reliance on older CNC lathes, which were slower and more prone to breakdowns, and labour-intensive practices that were affecting throughput and productivity. The company also recognised the need to improve the skills and knowledge of its turning employees to better utilise the advanced capabilities of the new machine.

The DNX 2100SB is well-suited for applications in sectors such as oil and gas, aerospace, motorsport, and automotive, where precision and efficiency are paramount. Its ability to perform complex machining operations in one setup aligns with the growing demand for well-engineered, customised tooling solutions that Cogsdill-Nuneaton is experiencing. This investment not only addresses current production challenges but also positions the company to meet future demand as it expands into new international markets.

Mills CNC continues to support Cogsdill-Nuneaton with its industry-established pre- and after-sales services, ensuring the company can maximise the potential of its new machine. The DNX 2100SB represents a significant step forward in Cogsdill-Nuneaton's ongoing commitment to continuous improvement and maintaining its position as a established provider of precision tooling solutions.

Cogsdill-Nuneaton's facility, spanning 27,000 square feet, now houses this advanced machine, which is expected to play a crucial role in the company's future growth and success. The DNX 2100SB is part of Mills CNC's broader portfolio of machine tools, which includes a range of high-performance models designed to meet the diverse needs of modern manufacturing environments.
