Guideways with Measuring System, Switzerland

Precise linear motion requires accurate distance measurement. SCHNEEBERGER, with its integrated distance measuring systems for a variety of applications, offers cost-effective solutions.

All systems are distinguished by the fact that it is possible to change the reading head with minimal assembly effort. Maximum one-piece rail length is 6 meters. The systems have been specially developed for the harsh environment in machine tools.

The AMSA length measuring system version has an analogue signal interface, AMSD has a digital interface. Both systems are offered for ball and roller guideways.

An absolute signal interface is available for the AMSABS version. Several MONORAILS can be joined together, as required. Then the AMSABS 3L product comes into play.

This combination is the result of the highly accurate construction of the rails in terms of both mechanics and metrology. The special design of the rail joints in combination with the AMSA 3L reading head allows joints to be traversed and measurement axes of any length to be set up.
In contrast, the strengths of the MINISCALE PLUS lie in guiding and measuring in the smallest of spaces.

This product is designed for high speed and acceleration in the work process, as practiced in high-tech industries.

The linear scale as the core of position measurement

The linear scale provides the physical reference for every length measuring system. In magnetoresistive systems, it consists of magnetised north and south poles with a constant pitch, integrated directly into the profile rail. This integration protects it against external influences and ensures precise geometric alignment between the guide point and the measuring point.

A critical advantage of integrated length measuring systems is that positioning the linear scale directly along the travel axis minimises Abbe errors. These occur when the measuring point and the point of action, such as the tool, do not lie on the same line. Angular deviations then lead to position errors proportional to the offset. SCHNEEBERGER reduces this Abbe offset to just a few millimetres.

Magnetoresistive sensors operate reliably even in the presence of contamination, coolant lubricants and mechanical influences. Unlike optical systems, which can be affected by particles, they provide high availability in machine tools and automation systems. The resolution is typically between 1 and 5 micrometres. For the highest accuracy requirements, MINISCALE PLUS complements the portfolio with optical measurement in the submicrometre range.

Integrated linear measurement systems - precise, compact and versatile

For the highest demands in position detection, SCHNEEBERGER offers two powerful measurement system categories:

Measurement system - analog or digital
The integrated distance measuring systems AMSA (analog) and AMSD (digital) position measuring systems enable incremental position determination directly in the profile rail guideway, with a choice of ball or roller guideways.

Absolute, magnetoresistive, with balls or rollers
The AMSABS system provides exact position data immediately after switch-on, without a reference run. AMSABS 3L is used for long axes.

Robust Position Measuring Systems for Demanding Applications

In industrial environments where precision and reliability are essential, robust position measuring systems play a key role. They must deliver accurate position data while withstanding harsh conditions - whether in factory automation, mechanical engineering or electronics manufacturing.

SCHNEEBERGER profiled guideways with integrated measuring systems combine high-precision measurement with mechanical stability in a compact, all-in-one solution. By fully integrating the measuring system into the guideway, not only is space saved, but a particularly durable and low-maintenance system is achieved.

Key advantages of this technology:

Space-saving design thanks to the combination of guideway and measuring system
High accuracy over the entire travel path
Resistant to dirt, dust, vibrations and temperature fluctuations
Reliable operation even under demanding environmental conditions
Wide range of applications, from automation to medical technology

The systems are available in both absolute and incremental versions. Absolute measuring systems deliver exact position data immediately after startup, without the need for a reference run. Incremental systems offer a cost-effective alternative with simple integration.

Whether in special machinery, high-precision production systems or complex handling processes - SCHNEEBERGER provides a robust and powerful solution for precise positioning and long-term reliability with its integrated measuring systems.
