Heidenhain TNC 426/430

The Heidenhain TNC 426/430 is part of the interchangeable control WinNC.

WinNC allows the user to learn all CNC industry controls that are common on the market on a CONCEPT machine or on a programmers place.

One of these controls is the Heidenhain TNC 426/430.

It corresponds in terms of handling and function to the particular original control and can also be installed on a PC.

The user has the possibility to work on the PC as well as on the machinecontrol and gets familiar with all aspects of control programming in detail.


Heidenhain 426

  • Horizontal and vertical control via softkeys like the industry control Heidenhain TNC 426/430

  • Graphic simulation with line graphics

  • Detailed error messages about drive problems and programming faults

  • Operation via PC keyboard, control keyboard, mouse or digitizer

  • Languages: German, English, Swedish, French, Spanish, Italian

  • Programs, tool data, pocket tables as well as zero and position offsets will be stored permanently

  • Program titles can be given individually

  • Window oriented, modern user interface

  • Comprehensive editor with intermediate memory storage function

  • Large NC program memory (limited only by the size of the hard disc)


Data in/output of workpiece program files

Workpiece program files can include several main and subprograms and further corresponding tool data. Moreover, workpiece data, R-parameter and zero offsets can be exported and imported.

Automatic measuring of tools

When scratching the reference workpiece the workpieces offsets will be taken over.

Automatic measuring of position offsets

When scratching the measured workpiece the position offsets will be taken over.

Dry run

In the run-up to the machining process collisions and programming mistakes can be avoided and corrected by using the dry run.

Preliminary block run

Already finalized NC codes can be skipped.


In order to ease the operation and the programming the control is equipped with an editor with helping cycles and pictures.

Contour processor with graphic simulation

The contours the workpieces should have after the machining process are illustrated by graphics in the programming process.


Alarms, signals, versions and customer information are displayed by the diagnostics.

Control software for all EMCO CONCEPT machines



Software demo / full version / homeschooling

Just give our WinNC software a try! All WinNC controls can be tested as demo versions free of charge and without obligation.

Our DEMO versions contain the full range of functions (only programming stations, direct control of machines is only possible via licensed software), but their useful life is limited to 30 days (from the date of installation).

By entering a valid license key all demo versions can easily converted into a full version or a homeschooling version at any time.

“Easy2control” adds a range of attractive applications to the successful interchangeable control system used in EMCO training machines.

Suitable for use in machines and simulation workplaces alike, it displays additional control elements directly on the screen and, when used together with a touchscreen monitor, provides the ideal input interface.

With support for a wide range of keyboard variants, customer-specific screen layouts and tailored solutions for individual customers, Easy2control represents a promising and highly flexible extension to the modular EMCO training concept.

The interchangeable controls are represented using an on-screen keyboard, which makes switching between different control systems even easier and quicker.

In the DEMO version of WinNC, Easy2control can be activated without a license key during the installation process or afterwards using the EMConfig configuration tool.


Portable Machine Operating panel to operate the machine via hardware, includes axis buttons, feed override switch, mode switch etc. together with EMCO Easy2control.


Das Robotik-Interface wird für den Anschluss der Concept-Maschinen an den FMS-/CIM-Betrieb benötigt.

EMCO Win3D-View

Win3D-View is a 3D simulation for turning and milling and is available as an option in addition to the WinNC Control. Graphic simulations of CNC controls are designed especially for industrial experience. Win3D-View displays exceed industry standards. Tools, blanks, clamping devices, and work processes are highly realistic. The system checks the programmed travel of the tool to prevent collision with clamping devices and blanks.

Concept machines

Whether for small businesses or for professional CNC training the Concept machines can be applied flexibly. With its modular concept the machine series can be used in a productional CIM network as well as for training purposes equipped with training softwares and coursewares.
