Hardware

This User’s Manual describes functions for setting up and operating the machine. These functions primarily depend on the installed software.
Software

The actual range of functions also depends on hardware enhancements and the enabled software options.

Avoiding electrostatic discharge when operating touchscreens

Touchscreens are based on a capacitive working principle, i.e. they are sensitive to electrostatic charges generated by the operators.

Users can discharge static electricity from their body by touching grounded metal objects. This problem can be avoided by wearing ESD clothing.

Capacitative sensors detect a contact as soon as a person’s finger touches the touchscreen. Touchscreens can even be operated with dirty hands, as long as the touch sensors are able to detect the skin resistance. While small amounts of liquid will not cause a fault, larger quantities of liquid will cause erroneous input.

 
Tip

Use work gloves to prevent the device from becoming dirty. The rubber material of special touchscreen work gloves contains metal ions that transfer the skin resistance to the display.

  • In order to maintain the functionality of the touchscreen, use the following cleaners only:
  • Glass cleaner
  • Foaming screen cleaners
  • Mild detergents
 
Tip

Do not apply the cleaner directly to screen, but slightly dampen a suitable cleaning cloth with it.

Switch off the control before cleaning the touchscreen. As an alternative, you can use the touchscreen cleaning mode.

Settings Application

 
Tip
  • Never use the following cleaners or cleaning aids, in order to avoid damage to the touchscreen:
  • Aggressive solvents
  • Abrasives
  • Compressed air
  • Steam cleaners

The TNC7 is delivered with various keyboard units.

The control is operated by means of touchscreen gestures and with the operating elements of the keyboard unit.

Machine

Refer to your machine manual.

Some machine manufacturers do not use the standard HEIDENHAIN operating panel.

External keys, e.g. NC START or NC STOP, are described in your machine manual.

Cleaning

 
Tip

Use operating gloves to prevent the device from becoming dirty.

In order to maintain the functionality of the keyboard, use only cleaners stated to contain anionic or nonionic surfactants.

 
Tip

Do not apply the cleaner directly to the keyboard unit. Slightly dampen a suitable cleaning cloth with the cleaner.

Switch the control off before cleaning the keyboard unit.

 
Tip
  • Never use the following cleaners or cleaning aids, in order to avoid damage to the keyboard unit:
  • Aggressive solvents
  • Abrasives
  • Compressed air
  • Steam blasters
 
Tip

The trackball does not require periodic maintenance. Cleaning is required only if the trackball stops functioning.

  1. If a trackball is embedded in the keyboard, clean the trackball as follows:
  2. Switch off the control
  3. Turn the pull-off ring by 100° in counterclockwise direction
  4. Turning the removable pull-off ring moves it upwards out of the keyboard unit.
  5. Remove the pull-off ring
  6. Take out the ball
  7. Carefully remove sand, chips, or dust from the shell area
  8.  
    Tip

    Scratches in the shell area may impair the functionality or prevent proper functioning.

  9. Apply a small amount of an isopropyl alcohol cleaner to a lint-free and clean cloth
  10.  
    Tip

    Please observe the information for the cleaner.

  11. 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

 
Machine

The IP54 protection rating cannot be guaranteed if the keyboard is missing any keys.

To exchange the keycaps:

Clipstastentausch_1
  1. Slide the keycap puller (ID 1325134-01) over the keycap until the grippers engage
  2.  
    Tip

    Pressing the key will make it easier to apply the keycap puller.

Clipstastentausch_2
  1. Pull off the keycap
Clipstastentausch_3
  1. Place the keycap onto the seal and push it down
  2.  
    Tip

    The seal must not be damaged; otherwise the IP54 protection rating cannot be guaranteed.

  3. Verify proper seating and correct functioning

Hardware enhancements

The hardware enhancements give you the possibility of adapting the machine tool to your individual needs.

The TNC7 features various hardware enhancements, each of which can be added separately and even subsequently by the machine manufacturer. The following overview includes only those enhancements that are relevant for you.

 
Tip

Keep in mind that particular hardware enhancements require additional software options.

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:
  • Portable or installed in the machine operating panel
  • With or without display
  • With or without functional safety

Electronic handwheels, for example, greatly simplify workpiece setup.

Electronic Handwheel

Workpiece touch probes

The control uses this enhancement for automatic and precise detection of workpiece positions and misalignments.

  • The workpiece touch probes have the following differing features:
  • With radio or infrared transmission
  • With or without cable

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

Tool touch probes

The control uses this enhancement for automatic and precise calibration of tools directly in the machine.

  • Tool touch probes have the following differing features:
  • Contact-free or tactile measurement
  • With radio or infrared transmission
  • With or without cable

Tool touch probes, for example, are useful for quick workpiece setup and for automatic correction of dimensions and breakage control during program run.

Vision systems

Use this enhancement to inspect the tools used.

With the VT 121 vision system, you can visually inspect the cutting edges during program run without removing the tool.

The vision systems help to avoid damage during program run, thus preventing unnecessary costs.

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 ITC 755 is a compact, additional operating station that mirrors the control's main screen, making it possible to operate the control.
  • The ITC 860 is an auxiliary screen that increases the area of the main screen. This allows multiple applications to be viewed simultaneously.
  •  
    Tip

    By adding a keyboard unit, the ITC 860 can be used as a full-fledged additional operating station.

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 (option 133), you can display the applications on the control’s screen.
