The HEIDENHAIN TNC7 is a new-generation CNC control system designed for milling, drilling, grinding, and mill-turn machines. With over 45 years of proven HEIDENHAIN control system reliability, the TNC7 takes productivity and precision to a whole new level. It is an intuitive, flexible, and powerful platform that supports the entire workflow—from initial design to finished product.
Advanced Operation and User Interface
The TNC7 supports users at every stage of operation—from programming and machine setup to workpiece measurement. Screen content is easily adapted to the current context, ensuring that the right information and functions are always accessible where needed. A special Dark Mode feature further simplifies use in low-light environments.
Smart Programming
The TNC7 enhances the well-known Klartext programming language with smart features. A newly developed graphical programming function allows users to draw contours directly on the touchscreen. The TNC7 then automatically converts the drawing into a Klartext program. Existing legacy Klartext programs can also be easily adapted and modified.
Familiar Operating Environment
The TNC7 retains familiar controls such as the classic TNC keyboard, ensuring excellent ergonomics even during extended use. Older NC programs remain compatible and can be used without issue. A guided introduction to the new functions further simplifies working with the TNC7.
Task-Focused Support
The TNC7 offers intelligently designed solutions including an extensive set of cycles, advanced probing functions, and graphical guidance for 6D alignment of fixtures and workpieces. Full visualization of both the workpiece and the working envelope enhances ease of use, alongside numerous new functions and workflows.
TNC Process Monitoring
The new Process Monitoring function helps users reliably achieve desired machining results with the TNC7. The control detects deviations from the reference machining process, monitoring all aspects of quality in serial production—from machine setup and machining operations to the finished part. No additional sensors or external computers are required.
Collision Protection
Advanced Collision Protection for Workholding Equipment
The TNC7 elevates Dynamic Collision Monitoring (DCM) to a new level. In this next-generation CNC system, DCM not only prevents collisions between tools and machine components but also between tools and workholding equipment. The graphically supported positioning process requires only an accurate 3D model of the fixture. The TNC7 then interactively guides the user through the entire procedure, allowing fast and precise localization using intelligent probing functions.
TNC Component Monitoring
The Component Monitoring feature in the TNC7 enables reliable implementation of extensive monitoring functions in machines. These include real-time process monitoring to prevent serious overload and data collection for predicting mechanical wear.
Optimized Contour Milling (OCM)
OCM offers many possibilities for reliable, low-wear machining under consistent process conditions. The user simply defines the contour, and the control automatically calculates the most effective trochoidal milling strategy. This allows highly efficient trochoidal milling to be used across a wider range of workpieces, improving productivity and reducing tool wear.
