Intelligent and innovative solutions for machine tools and manufacturing automation – under the motto 'Empower Manufacturing', HEIDENHAIN, along with the brands AMO, ETEL, NUMERIK JENA, and RSF, will present exciting innovations and developments at EMO 2025 in Hannover, enabling machine builders and users to manufacture even more efficiently and agilely.
More possibilities for manufacturing: With the expansion of the functionality and product portfolio of the TNC7 controls, HEIDENHAIN opens up new application areas and machining technologies for machine manufacturers and users:
- Cylindrical grinding and contour planing, as well as new possibilities for cylindrical surface machining, expand the functionality of the TNC7 for complete machining. Visitors to the trade fair can experience the new capabilities live during demonstrations at the HEIDENHAIN booth.
- Further enhanced simulation functions ensure that NC programs can be checked in detail even before execution and run process-safely on the machine.
- HEIDENHAIN teaches robots plain language. This enables the control of the robot at an automated machine tool directly via the TNC controls.
- The TNC7 go brings the forward-looking, intuitive operating concept of the TNC7 family tailored to the application areas of training and retrofit.
For complete machining and manufacturing of workpieces with the highest dimensional and geometric accuracy as well as surface quality, the TNC7 controls now offer the technologies of contour planing and cylindrical grinding. Milling, turning, and grinding – the TNC7 provides users with various technologies that can be easily applied without re-clamping on a single machine.
With contour planing or shaping, users can produce sealing surfaces with high surface quality, as required in battery manufacturing or the semiconductor industry. The control automatically positions the planing tool perpendicular to the contour. The user does not need to program the spindle angle. The control automatically takes into account a tilted machining plane as well as a tool offset. With appropriate tools, users can also use contour planing to bevel edges with special surface requirements or engrave patterns into a surface – a requirement from printing technology or the jewelry and watch industry, among others.
At EMO, HEIDENHAIN will also present the first functions for cylindrical grinding with the TNC7 control. This further increases the potential of machining centers for complete machining with milling, turning, and grinding on a single machine. Standardized cycles are available for cylindrical grinding as well as for dressing grinding wheels. The cycles support both long-stroke and short-stroke grinding of rotationally symmetrical workpieces. Pendulum and feed movements occur independently of each other.
This makes it possible to optimize the machining process already during approach without changing the NC program. The cycles also automatically take into account the machine kinematics during approach and departure. This relieves the user, especially with complex machines and difficult starting conditions.
TNC7 and TNC7 basic also offer new possibilities for cylindrical surface machining. A cylindrical surface transformation now allows the already extensive cycles for cylindrical surface machining to be applied to almost all milling, drilling, and engraving processes on the cylindrical surface. The tool must be positioned perpendicular to the axis of the rotary table and the cylindrical workpiece. After activating this transformation, the user can easily program the required cycles and movements on the cylindrical surface. The rotary table then replaces the radial movement direction of this surface during machining.
Two new functions will enhance the extensive simulation capabilities of a TNC7 starting from EMO 2025 and facilitate the verification of NC programs based on machine simulation. By forward and backward spooling of the simulation and thus the movements of the tool, including the entire machine kinematics in the simulated TCP path, the user can specifically examine critical motion movements. The clear presentation of detected warnings and errors in a simulation report also facilitates efficient and effective error analysis.
The user can decide whether messages from the simulation are displayed as before in the notification menu of the information bar or related to an NC program in the verification column in the program workspace.
HEIDENHAIN simplifies the operation of handling robots at automated machine tools with a new solution: The user operates and programs the robot directly via the TNC – completely without separate knowledge of robot control. They use a unified interface for operating their machine tool and the robot. The programming of the robot is done via plain language cycles, particularly easy through the integrated teach-in processes. Additionally, the user can flexibly integrate various robot functions such as pick & place, deburring, or gripper control. The connection of the robot control to the TNC is done via Ethernet and does not require bus systems, allowing existing machines to be easily retrofitted.
With the TNC7 go, HEIDENHAIN brings the forward-looking, intuitive operating concept of the TNC7 family now tailored to the application areas of training and retrofit – and expands the previous possibilities with practical functions that noticeably simplify everyday work. This includes particularly the new function 'Graphical Positioning'. Instead of writing an NC program, the user directly draws the desired drilling positions, contours, or patterns on the touchscreen. The control automatically takes over the execution. Equally helpful are the new 'Manual Cycles', which enable typical machining tasks such as drilling or face milling without programming. With these features, the new TNC7 go is ideal for beginners in working with machine tools. But even for professionals who want to achieve results quickly, the new functions will be appreciated. The TNC7 go thus stands for efficient work, fast learning, and a user-friendly CNC experience – perfectly tailored to the needs of modern training facilities, workshops, and retrofit projects.
