For more than 35 years, TNC controls from HEIDENHAIN have been proving themselves in daily use on milling, drilling and boring machines, as well as machining centers. While the controls have undergone continuous development during this period, the basic operational technique has remained the same. You will find also these principles implemented in the TNC 640, the HEIDENHAIN contouring control for milling and milling/turning operations: shop-oriented programmability with graphic support, many field-proven cycles and an operational design you'll recognize from other HEIDENHAIN controls. Shop-oriented programming You program conventional milling and drilling operations, and with the TNC 640 also turning operations, yourself at the machine, in plain language dialog—the workshop-oriented programming language from HEIDENHAIN. The TNC 640 provides you with optimum support with practical prompts, questions and expressive graphical aids—for turning operations, too.

In rotary encoders with integral bearing and stator coupling, the graduated disk of the encoder is connected directly to the shaft to be measured. The scanning unit is guided on the shaft via ball bearings, supported by the stator coupling. During angular acceleration of the shaft, the stator coupling must absorb only that torque resulting from friction in the bearing, thereby minimizing both static and dynamic measuring error. Moreover, the coupling mounted on the stator compensates axial motion of the measured shaft. Other benefits of the stator coupling are: Simple mounting Short overall length High natural frequency of coupling Hollow-through shaft possible HEIDENHAIN ERN, ECN and EQN rotary encoders with integral bearing and mounted stator coupling are characterized by simple mounting and short overall length.

The EIB 700 evaluation electronics feature connections for four axes. They are ideal for precise position measurement in particular for inspection stations and multipoint inspection apparatuses as well as for mobile data acquisition, such as in machine calibration. The EIB 700 series are ideal for applications requiring high-resolution encoder signals and fast measured-value acquisition. Ethernet transmission also enables you to use switches or hubs for connecting more than one EIB. It is also possible to use WLAN transmission, for example.

Interface electronics from HEIDENHAIN adapt the encoder signals to the interface of the subsequent electronics. They are used when the subsequent electronics cannot directly process the output signals from HEIDENHAIN encoders, or if additional interpolation of the signals is necessary. HEIDENHAIN interface electronics are available in various mechanical designs. Version for integration There are also versions of the interface electronics intended for integration in existing electronics. These pluggable boards must be protected against electrical and physical influences. The IDP series consists of pure interpolation and digitizing electronics, and is intended for integration as input assemblies in non-HEIDENHAIN electronics.

Rotary encoders without integral bearing operate without friction. The two components - the scanning head and the scale disk, drum, or tape - are adjusted to each other during assembly. The benefits are: Large diameter of hollow shaft For high shaft speeds No additional starting torque In addition to the system accuracy, the mounting and adjustment of the scanning head normally have a significant effect on the accuracy that can be achieved with rotary encoders without integral bearings. Of particular importance are the mounting eccentricity and radial runout of the measured shaft. The inductive rotary encoders ECI/EQI 1300 are mechanically compatible with the photoelectric encoders ExN 1300: the shaft is fastened with a central screw. The stator of the encoder is clamped by an axially tightened screw in the location hole.

The aluminum housing of a HEIDENHAIN sealed linear encoder protects the scale, scanning carriage, and its guideway from chips, dust, and fluids. Downward-oriented elastic lips seal the housing. The scanning carriage travels along the scale on a lowfriction guide. It is connected to the external mounting block by a coupling that compensates unavoidable misalignment between the scale and the machine guideways. For typical applications on manual machine tools such as milling machines or lathes, display steps of 10 µm or 5 µm are suffi cient. Such display steps are provided by the LS 300 and LS 600 series linear encoders with an accuracy grade of ± 10 µm per meter traverse.

The TT 160 and TT 460 tool touch probes aretouch trigger probes for the measurement and inspection of tools. The TT 160 features signal transmission by cable, while the TT 460 communicates wirelessly over a radio or infrared beam with the SE 660 transmitter/receiver unit. The disk-shaped probe contact of the TT is defl ected during physical probing of a tool. At that moment the TT generates a trigger signal that is transmitted to the control, where it is processed further. The trigger signal is generated through a wear-free optical switch that ensures high reliability. The probe contact is easy to exchange. The connection pin to the contact plate features a rated break point. This protects the touch probe from physical damage due to operator error.

The ultra-fast M8coolHB pressure transmitter can process pressure changes with a bandwidth of 50 kHz. This is achieved by means of the continuous analog signal that is adjusted by a digital circuit in real time and is amplified to a standardised 0...10V signal. The miniature sensor head with a fine M8 thread can withstand temperatures of up to 1000 °C with suitable cooling, is overload-proof up to a magnitude of five times the measuring range, and is also resistant to vibrations.

The differential pressure transmitters of the PRD-33X series are designed for accurate measurements in low pressure ranges with very high overload on both sides. In addition to the differential pressure sensor, which may only be exposed to gases at its rear face, the devices have an additional absolute pressure sensor that measures the line pressure. Both measured values are output via the digital RS485 interface and are the ideal basis for cryogenic tank monitoring.

The front-flush pressure transmitters of the 35X-Ei series use digital compensation with a mathematical model to achieve exceptional accuracy of 0,05 %FS – in the temperature range from 10 to 40 °C, this value even corresponds to the total error band. In addition to the digital RS485 interface, the X-line transmitters have a rangeable, analog current or voltage output. Intrinsically safe – suitable for use in explosive atmospheres.
