Europe’s CNC skills gap is often framed as a workforce shortage, with manufacturers urged to recruit more machinists, programmers and experienced operators to meet growing demand. While this is undoubtedly part of the challenge, it does not tell the full story. The European Labour Authority (ELA) reports widespread shortages across multiple sectors, leaving many roles unfilled and limiting how effectively businesses can run production. Here, Hakan Aydoğdu, CEO at CNC automation specialist Tezmaksan, explores why utilisation, not headcount, is becoming the defining metric of manufacturing performance.
Across sectors like aerospace and general manufacturing, demand remains strong. However, many facilities still struggle to turn installed capacity into consistent throughput. According to Make UK, the UK’s leading manufacturers’ organisation, manufacturers are keen to automate, but cite a lack of technical skills and labour availability as key barriers. In practice, these constraints don’t just affect hiring, they limit how effectively machines and automation can be used day to day.
It’s a familiar scenario. Advanced CNC machines sit idle between jobs, during shift changes or overnight. Not because they lack capability, but because there aren’t enough operators available to keep them running. Over time, this creates a widening gap between what a machine could produce and what it delivers.
The impact shows up quickly. Delivery dates slip, lead times increase and taking on new work becomes challenging. In some cases, manufacturers are even turning jobs away, not because they lack equipment, but because they can’t maintain consistent production across multi-part runs or sustain output beyond staffed hours. The issue is no longer machine capability, it’s operator availability acting as a bottleneck.
This constraint isn’t happening in isolation. The European Union (EU), has reported that around 51 million working-age people were outside the labour market in 2025, highlighting the gap between available jobs and available skills. For manufacturers, this translates into unfilled roles and lost production potential.
When capacity goes unused
The skills shortage is often treated as a recruitment and training issue. While those remain important, it assumes that adding more people is the only way to increase output. Many workshops already have the machines they need, they just aren’t getting the most out of them.
Spindle utilisation is a good example. A machine may be capable of running continuously, but in practice it often operates for only a fraction of the day, particularly in high-mix, low-volume environments where frequent setups, manual loading and operator availability interrupt cycle time. Over time, those lost minutes and hours translate into significant unused capacity.
This becomes even more evident in complex production environments, As part variety increases and batch sizes shrink, reliance on skilled operators grows. The result is a cycle where machines spend more time waiting for operators, for setup, loading or intervention, rather than running productively. The opportunity, therefore, is not just in recruitment, but in unlocking the capacity already sitting on the shop floor.
Automation as a utilisation strategy
Automation can shift the conversation, not as a replacement for skilled workers, but to make better use of them. By enabling one operator to oversee multiple machines, automation reduces the reliance on one-to-one machine tending. It also allows production to continue beyond traditional working hours, supporting lights-out or unattended machining without compromising consistency.
In practical terms, this means less idle time between cycles, fewer delays during shift changes and more stable, predictable output, particularly in high-mix environments where manual intervention would otherwise limit throughput. Even small increases in utilisation, repeated over time, can make a significant difference to overall capacity.
For many manufacturers, this changes how growth is approached. Instead of investing in additional machines, they can increase output by getting more from the equipment they already have. Automation becomes a way to close the gap between installed capability and actual production.
CNC automation systems like CubeBOX, a modular robotic machine tending cell, integrate with existing CNC machines to automate loading and unloading, reducing idle time between cycles, enabling unattended operation and allowing a single operator to manage multiple machines simultaneously. Combined with ROBOCAM+ software, they help extend operating hours, increase utilisation and maintain consistent production across changing workloads.
A shift in perspective
Labour shortages aren’t going away any time soon. But the way manufacturers respond to them is evolving.
Rather than treating the issue purely as a workforce challenge, more businesses are starting to see it as a question of utilisation and operational efficiency. That shift opens up new ways to improve performance, not by adding more people, but by making better use of machines, automation and available skills. Ultimately, the question is no longer how many machines a factory has, but how effectively they’re used.
