Hardware
This User’s Manual describes functions for setting up and operating the machine. These functions primarily depend on the installed software.
The actual range of functions also depends on hardware enhancements and the enabled software options.
The control must have at least 16 GB of RAM, as the control will otherwise display a warning.
Touchscreen and keyboard unit
16" MC 345 with TE 340 (FS) |
The TNC7 basic is delivered with a 16-inch screen.
The control is operated by means of touchscreen gestures and with the controls of the keyboard unit.
Common gestures for the touchscreen
Operating elements of the keyboard unit
The machine operating panel is machine-dependent.
Operating and cleaning the touchscreen
Touchscreens can even be operated with dirty hands, as long as the touch sensors are able to detect the skin resistance. Small amounts of liquid do not affect the function of the touchscreen, but large amounts may cause incorrect input.
Switch off the control before cleaning the touchscreen. As an alternative, you can use the touchscreen cleaning mode.
Do not apply the cleaning agent directly to the screen, but slightly dampen a clean, lint-free cleaning cloth with it.
The following cleaning agents are permitted for the screen:
- Glass cleaner
- Foaming screen cleaners
- Mild detergents
The following cleaning agents are prohibited for the screen:
- Aggressive solvents
- Abrasives
- Compressed air
- Steam cleaners
- Touchscreens are sensitive to electrostatic charges from the user. Dissipate the static charge by touching metallic, grounded objects or wear ESD clothing.
- Wear operating gloves to prevent the screen from getting dirty.
- You can operate the touchscreen with special touchscreen operating gloves.
Cleaning the keyboard unit
Switch the control off before cleaning the keyboard unit.
- Use permitted cleaning agents only
- Use a clean, lint-free cleaning cloth to apply the cleaning agent
The following cleaners are permitted for the keyboard unit:
- Cleaning agents containing anionic surfactants
- Cleaning agents containing nonionic surfactants
The following cleaning agents are prohibited for the keyboard unit:
- Cleaning agents for machines
- Acetone
- Aggressive solvents
- Abrasives
- Compressed air
- Steam cleaners
Wear operating gloves to prevent the keyboard unit from getting dirty.
If a trackball is embedded in the keyboard, you need to clean it only if it no longer works properly.
To clean a trackball (if needed):
- Shut down the control
- Turn the pull-off ring by 100° in counterclockwise direction
- Turning the removable pull-off ring moves it upwards out of the keyboard unit.
- Remove the pull-off ring
- Take out the ball
- Carefully remove sand, chips, or dust from the shell area
- Tip
Scratches in the shell area may impair the functionality or prevent proper functioning.
- Apply a small amount of the cleaning agent onto a cleaning cloth
- Carefully wipe the shell area clean with the cloth until all smears or stains have been removed
Exchanging keycaps
If you need replacements for the keycaps of the keyboard unit, contact HEIDENHAIN or the machine manufacturer.
Keycaps for keyboard units and machine operating panels
IP54 protection cannot be guaranteed if the keyboard is missing any keys.

Hardware enhancements
The hardware enhancements give you the possibility of adapting the machine tool to your individual needs.
The TNC7 basic features various hardware extensions that the machine manufacturer may add separately, even at a later point in time. The following overview includes only those extensions that are relevant to you.
Keep in mind that particular hardware enhancements require additional software options.
Hardware enhancements | Definition and application |
---|---|
Electronic handwheels | You use this enhancement for exact manual positioning of machine axes. The wireless portable variants improve ergonomics and increase versatility. The handwheels have the following differing features:
Electronic handwheels, for example, greatly simplify workpiece setup. |
Workpiece touch probes | The control uses this enhancement for automatic and precise detection of workpiece positions and misalignments (#17 / #1-05-1). The workpiece touch probes have the following differing features:
Workpiece touch probes, for example, are useful for quick workpiece setup and for automatic correction of dimensions during program run. Touch probe functions in the Manual operating mode (#17 / #1-05-1) |
Tool touch probes | With this extension, the control can measure tools automatically and precisely, directly in the machine (#17 / #1-05-1). Tool touch probes have the following differing features:
Tool touch probes, for example, are useful for quick workpiece setup and for automatic correction of dimensions and breakage control during program run. Touch-probe cycles for tools (#17 / #1-05-1) |
Additional operating stations | This enhancement adds a second screen, to facilitate operation of the control. The additional ITC (industrial thin client) operating stations are differentiated by their intended use:
The additional operating stations increase operator comfort, especially on large machining centers. |
Industrial PC | You use this enhancement to install and run Windows-based applications. With Remote Desktop Manager (#133 / #3-01-1), you can display applications on the control screen. The Remote Desktop Manager window (#133 / #3-01-1) The industrial PC is a secure and powerful alternative to external PCs. |
Override controller | This extension allows you to define breakpoints at which the control stops during program run (e.g., before a tilting function). The override controller enables the feed rate or rapid traverse value to be changed as well as starting or continuing the NC program. |
