Company

Shortly after the Second World War, mechanical engineer Dr.-Ing. Siegfried Werth founds a company in Düsseldorf for the development and manufacture of measuring machines. The first products are geared towards applications in the wire industry.

The Record E is the first Werth profile projector for comparing workpieces with design drawings. The console design makes it easier to operate than conventional models.

The company relocates to Giessen, a region with a long tradition in precision mechanics and optics manufacturing.

The first optoelectronic fiber sensor for edge detection for measuring projectors, which allows automatic measurement of workpiece edges

The first CNC projector enables the fully automatic optical measurement of workpieces with micrometer accuracy.

Due to serious illness, Dr. Werth sells the company to the Giessen-based Schunk Group. The new name of the company is now Schunk-Werth Messtechnik GmbH.

The 2D CAD software HP ME10 forms the basis for the offline programming of measuring projectors with the optoelectronic sensor Werth Tastauge. The programs are transferred to the control code of the machines with the help of a post-processor.

The first multisensor coordinate measuring machine is equipped with a laser distance sensor integrated into a telecentric two-stage zoom for image processing. The fully automatic three-dimensional measurement of workpieces is now possible with optical sensors.

The software for automatic contour comparison in conjunction with optical contour scanning creates the modern successor to the profile projector.

The compact coordinate measuring machine with PC-based image processing and the Windows operating system with graphically interactive operation is groundbreaking for the industry (here the modern successor to the prototype at the time). Multi-sensor coordinate metrology becomes affordable and easier to use.

During the economic crisis of 1992/93, the company's then head of development, Dr.-Ing. habil. Ralf Christoph, took over the majority of the shares and continued to run the company under the traditional name of Werth with 40 employees at the beginning.

The Werth Laser Probe integrated into the image processing beam path enables fast and accurate surface scanning for contour and flatness measurements.

Werth Messtechnik France SARL is founded as the first company abroad. The company is based in the south of Paris and coordinates sales and service activities.

Linear drives and OnTheFly technology make the world's fastest coordinate measuring machine possible (in the image, the modern successor to the prototype at the time).

WinWerth®-integrated offline programming, at that time still based on 2D CAD data, allows program creation before production of the first workpieces with the same software as teach-in on the measuring machine. With the WinWerth® CAD-Online® function, the measuring machines can be controlled directly with CAD data for the first time.

The opening of the new demonstration and training center adapts the capacity to the increased variety of devices and number of demonstrations and training courses for customers.

The first representative of the successful ScopeCheck® series (in the image the modern successor) is tailored to the requirements of production-related metrology. Robust mechanical guideways and the powerful Werth sensors offer reliable measurement results.

Together with the Physikalisch-Technische Bundesanstalt (PTB), the smallest and for many applications most accurate micro-probe for coordinate measuring machines is developed (patent) and forms the basis for Werth's special competence also in the measurement of micro-geometries. The modern Werth Fiber Probe® is probably the most widely used micro-probe in the world.

The world's fastest multisensor coordinate measuring machine for highly accurate tool measurement is also based on linear drives, image processing and Werth Fiber Probe®.

For the first time in optical coordinate metrology, both magnification and working distance can be set automatically. The patented Werth zoom optics creates a flexible solution for optical measuring tasks and is still a special feature of Werth today.

The ToleranceFit® software for automatic contour comparison is extended by a new patented function for automatic gauging using the tolerance zones.

The unique incident light illumination (patented) in combination with the Werth Zoom allows a particularly high-contrast image of workpieces. Reliable measurement results even under difficult conditions are the benefit.

Intelligent algorithms in the software automatically recognize the geometric elements to be measured, a milestone in simple operation (patented).

The 2D scanner for the precise measurement of 2D workpieces (patented) is based on coordinate metrology components. The design of the optical beam path allows fast measurement without focusing, as with the traditional desk projector (in the image a larger version of the prototype at the time).

The sales and service center for the USA is opened in Old Saybrook, Connecticut. Several regional service centers are established in the USA by 2020.

The first German DKD calibration laboratory accredited according to ISO 17025 (Deutscher Kalibrierdienst – today DAkkS laboratory) for optical and multisensor coordinate measuring machines is located at Werth.

The Werth multi-sensor systems are supplemented by the tactile-optical Werth Contour Probe (patented) for standard-compliant roughness measurements in any orientation.

The Werth Laser Probe is integrated into the Werth Zoom (patent).

The world's first machine with X-ray computed tomography (CT) specially developed for coordinate measuring technology can be optionally equipped with multi-sensor systems (patent). Werth thus lays the foundation for a new branch of coordinate metrology. By combining components and methods from conventional coordinate measuring technology, CT technology makes it possible for the first time to measure 3D workpieces quickly and completely (inside and outside) with high accuracy.

The letters UA stand for "Ultra Accuracy" and describe the aim of the device concept. The multi-sensor coordinate measuring machine with 1 nanometer resolution, high temperature stability and many other special technical features is still the most accurate commercial multi-sensor coordinate measuring machine thanks to ongoing further development.

The machine uses ScopeCheck® technology with an integrated rotary axis for vertical pick-up and measurement of rotationally symmetrical parts.

The computed tomography coordinate metrology system with the highest resolution and accuracy is now also available for large and difficult-to-transmit parts.

The TomoScope® L is a successful compromise between high X-ray voltage up to 240 kV and small device dimensions.

The 3D version of the proven micro-probe is realized by a combination of laser distance and image processing sensor with the fiber probe principle.

The number of employees has risen to over 200 and turnover has increased many times over.

Werth Messtechnik GmbH and mt microtool GmbH merge their activities in tool metrology to form Werth Tool MT GmbH. As a specialist in the measurement of cutting tools, Werth now offers users the perfect combination of highly accurate and universal device technology paired with over 25 years of experience in the field of tool measurement.
