Working closely with trusted partners, Heller has accumulated the expertise needed to integrate digital solutions with AI elements into machining cells and is already applying the technology across three platforms, intended to support machine operators, production planners and service personnel.
The way in which these developments are delivering added value will be presented at the EMO 2025 exhibition in Hannover, to be held from September 22-26.
Visitors to the stand will be able to witness live demonstrations on two Heller 5-axis machining centres, the HF 3500 and F 5000. Both models will be equipped with new automation solutions for workpiece and tool handling respectively. The manufacturing cells enable automated production of complex components, especially in the aerospace, hydraulics and pneumatics, and power generation sectors.
Several years ago, the company formed a cross-departmental team of specialists dedicated to digitalisation and AI, with the remits to make machine operation more efficient and to enable predictive maintenance and production planning.
“We are concentrating on these three key areas, as AI delivers real advantages. At EMO, we will present practical applications and the concepts behind them. The way in which operators are digitally supported throughout the entire process chain will be demonstrated," said Dr Thorsten Schmidt, CEO of Heller and a driver of this initiative.

Operators have access to AI-powered software and system functionalities, including SETUP-Assist, PRODUCTION-Assist and, to ensure component accuracy, the newly developed QUALITY-Assist. Additionally, by measuring temperature increases in the spindle, even the smallest growth can be calculated and compensated for, allowing the machine to maintain maximum precision and productivity without any specific operator intervention.
A new feature to be introduced at EMO provides customers with an intelligent chat function, ASK-me. This tool, integrated into the control interface, provides operators with a ChatGPT-like assistant. Users are able to enter questions in plain language, after which the AI function quickly delivers clear, straightforward answers. The AI assistant uses the collective expertise of Heller and its users to provide answers and support relating to machine operation, including setup and maintenance, and helps to interpret warning and error messages.
Heller will also showcase its AI-powered analysis tools, which offer valuable benefits for maintaining the productivity and high precision of modern machining centres. To achieve this, the Nürtingen-based machine manufacturer uses data collected as part of its Industry 4.0 strategy.
The information can be visualised by production planners and analysts via the shop floor system Heller Services Interface in the form of text, tables or diagrams. It ensures transparency in production, maintenance and service throughout the lifecycle of the machine.
For instance, machine downtime can be identified using a generatively produced chart, whilst AI-supported analysis of production data helps to reveal potential for boosting output. Heller service engineers will show how the combination of data acquisition and intelligent analysis provides key insights for preventive maintenance.
Notable also will be a demonstration of how quickly and easily tools can be changed in batches using a newly developed rack-type tool magazine connected to the F 5000. With this type of automated tool changeover, several worn tools are removed from the machine together in a single cassette and replaced with new tools that have been preset and placed in a mobile rack. Owing to their slimline design, the new rack magazines offer an optimised footprint and can store up to 340 HSK-A 100 tools or approximately 490 HSK-A 63 tools. A version with 260 pockets will be on display at the trade fair.
