Cogsdill Nuneaton Ltd has strengthened its turning operations following investment in a
DNX 2100SB multi-tasking mill-turn machine supplied by Mills CNC. Installed in December
2025, the machine is playing a central role in the company’s drive to improve efficiency,
increase capacity and move towards lights-out production.
The DNX 2100SB, one of the first installed in the UK, supports the machining of complex,
high-precision parts in a single set up. Equipped with twin spindles, a B-axis milling head, 60-
tool ATC and FANUC control, the machine also incorporates a Hydrafeed bar feeder, rotary
parts accumulator and Renishaw probing and tool-setting systems to support automated,
unattended operation.
The investment follows an internal audit of Cogsdill Nuneaton’s turning section, which
identified bottlenecks caused by ageing CNC lathes and labour-intensive processes.
According to managing director Lee Donaldson, the decision to invest in a multi-tasking
machine from Mills CNC was influenced by previous positive experience of Doosan machines
supplied by the company, as well as its strong pre- and after-sales support. Training
provided by Mills CNC ensured a smooth transition to the new FANUC-controlled platform,
helping operators and programmers quickly become productive.
Since installation, the DNX 2100SB has been busy machining small batches of precision
components for the company’s standard tooling products in a single hit, achieving tight
tolerances, excellent roundness and high surface finishes.

Ultimately, the investment marks a significant step forward in productivity, flexibility and
overall machining capability. Looking ahead, Cogsdill Nuneaton plans to expand the
machine’s role to include more complex and custom parts, while introducing overnight
unattended running.
