Dynamic Torque Calibration

In the production of high-grade milling parts, the monitoring of the machine parameter is an important tool to guarantee the required quality standard and to optimize the tool lifetime. With the regular calibration of the machine tools sensors, the machine monitoring system can be checked and adjusted in order to maintain a constant data quality. The regular calibration process under real conditions is at the same time a meaningful documentation of the quality of the production towards notified bodies or government authorities.
The torque calibration unit, copies the torque a rotating cutting tool meets, when machining a work piece, and applies it to the tool head drive, while rotating. The accurate and dynamically controlled torque can be applied to any spindle in motion, regardless of axis and position, including upside down.
The calibration process is performed by an operator manually or auto controlled by the machine, same applies to the data exchange.

Dynamic Feed Force Calibration

In the production of high-grade milling parts, the monitoring of the machine parameter is an important tool to guarantee the required quality standard and to optimize the tool lifetime. With the regular calibration of the machine tools sensors, the machine monitoring system can be checked and adjusted in order to maintain a constant data quality. The regular calibration process under real conditions is at the same time a meaningful documentation of the quality of the production towards notified bodies or government authorities.
The feed force calibration unit emulates a material, which is penetrated by a cutting tool, by providing a controlled resitance to the feed axis while moving. The feed force calibration tool can operate in any working position and on any travel axis inside the workspace of the machine.
The calibration process is performed by an operator manually or auto controlled by the machine, same applies to the data exchange.

EPC - pressure calibration unit

The pressure calibrators of the EPC Series offer a wide range of complete pressure calibration solution for sensors and switches.

The available range of pressure goes from 0,1 mbar (10 Pa) to 300 bar. Any combination of pressure ranges is possible in a multi channel unit.

The dynamic controller can precise map pressure gradients and curves up to 250 Hz. That makes the units suitable for applications such as simulation of blood circulation or marine propellers.

Our pressure calibrators meet the highest standards of accuracy requirements and are subject to the authorities as calibration and testing systems in nuclear power plants.

Most non corrosive gases and liquids may be used as medium.

The available data interfaces (TCP/IP, USB, CAN, IEEE 802.11n, RS485, SD card) and the flexible software interface, simplifies the integration into existing test rigs.
For the development environments C, Delphi and LabView we supply examples including source code.

EDC - leakage test device

Our leakage test devices are designed for mobile use, with little effort to check HEPA filters, fire shutters and pipework.

The compact design with integrated power and pressure supply,allows operation without external connections.
To perform the test, the device is connected to the test port of the system. The test is automated and the results are visualized on the screen, and stored in the internal memory, for later usage.

The autonomous period of use depends on the amount of leakage, but is at usual test conditions several hours.

DS-nCH - pressure scanner

The portable pressure scanner (DS-nCH) acquits simultaneous pressure signals (e.g. from flow probes). The pressure data is continuously recorded and on request the current values are transmitted.

Each pressure measuring channel can be equipped with any pressure measuring cell inside the available range.

If required, the pressure sensors can be adjusted by the user via the digital interface using a 2-point calibration (tara, full scale) be readjusted.

The available data interfaces (TCP/IP, USB, CAN, IEEE 802.11n, RS485, SD card) and the flexible software interface, simplifies the integration into existing test rigs.
For the development environments C, Delphi and LabView we supply examples including source code.

Massflow Test-Benches

We develop economic overall concepts and test strategies for mass flow test benches. The services include designing and manufacturing of the test benches, that are specially tailored to the requirements of the client. For the test procedures we create test bench control programms individually, according to the specifications, and existing production line.

corporate information

Walcher Elektronik GmbH specializes in the development of static and dynamic test systems.

We offer holistic procedures for the calibration and the condition monitoring of additive and cutting machine tools.

Since the company was founded in 1980, we have been developing and producing prototypes and small series with a focus on:

• dynamic calibration equipment for machine tools
• pneumatic / hydraulic pressure and volume flow measuring and control systems
• Measuring devices for mobile use in demanding environments
• Leak testing devices for large structures and pipes (e.g. containment, protective shutters)

The focus of our projects is always on optimizing the customer-specific application.
The modular structure and scalability of our hardware and software enables easy integration even in heterogeneous environments.
If special industrial standards like KTA1402 (nuclear) or AS/EN9100 (air/space) are required, our systems are designed and qualified accordingly.

The constantly increasing requirements in additive and cutting production, and the resulting new possibilities and demands on measurement technology are an exciting environment in which we will continue to offer new and innovative solutions in the future.
