Advanced Integrated Measuring System from SCHNEEBERGER

The concept of integrating a linear magnetic scale into a precision linear motion guide was invented by Schneeberger back in 1992 and applied to its Monorail series of high-capacity, high-stiffness roller guides. The combination technology provides machine designers with a cost-saving and more robust alternative to linear glass scales, which require additional hardware, significant assembly time and close alignment with the guides for proper performance.
Linear scales provide machines with positioning feedback in all three axes for optimal machining accuracy and repeatability. Each Schneeberger Advanced Measuring System includes a hard cover band that protects the magnetic scale from accidental physical damage that could lead to signal decay. In addition, all AMSA (Generation 3.0 and higher) use new, wear-free ceramic sliding elements on the electronic scanning head for long-term protection against contamination.AMSA uses an electronic scan head that attaches to the Schneeberger guideway carriage. The Schneeberger AMSD 3-A is available in roller guide sizes MR25, 35, 45, 55 and 65 and the AMSD 4-A is available in ball guide sizes BM15, 20, 25, 30, 35, 40, and 45.
Scales for both versions feature resolution of 0.2 to 5 microns, distance coded reference marks at 50mm intervals, A quad B signals RS422 with reference and error signal, reference pulse width 90° or 500 µs for FANUC-CNC. Operating temperatures of up to +70° C and storage temperatures of -20 to +70°C are possible.
Over eight-thousand installations of Schneeberger integrated scale guides have been installed throughout the world. Machine tools are the most popular application for the integrated linear scale because of its greater durability and smaller space requirements than glass scales. In addition, the AMSA is impervious to oil, grease, coolants and vibrations from machining operations. In extremely contaminated environments additional wiper seals are available to move large metal chips and other types of debris.
