Vibration-damping & highest precision
Material and technology
Mineral casting (EPUMENT®)
EPUMENT® mineral casting is a high-tech material that is perfect for the primary machine bed functions, such as precisely securing the geometric position of the individual machine elements, and the static, dynamic, thermal, and acoustic absorption of forces and moments.
Ultra-high performance concrete (EPUDUR)
EPUDUR is an ultra-high performance concrete (UHPC) based on the latest generation of premium cements. It has been further developed from Mikrodur technology using nano-structured synthetic silica.
Hard stone (EPUSTONE)
Industrially mined hard stone (commonly known as granite) has been used for several decades for measuring plates, straightness and angle standards, and machine bed components for measuring and high-precision production machinery. Hard stone is an isotropic, homogeneous material that follows Hooke’s law and can be analyzed using linear-elastic FEM modeling.
Composite constructions (EPUFILL)
For four decades, cavities in steel or cast iron machine beds and machine bed components have been filled with epoxy resin-bonded mineral casting. Initially often used to subsequently improve dynamic performance, this has since become a process in its own right.
Your machine frame with the best properties of mineral casting
Hervorragende thermische Stabilität: Niedrige Wärmeleitfähigkeit bewirkt träge Reaktion auf Temperaturschwankungen.
Überragende Schwingungsdämpfung: 10-mal besser als Grauguss.
Designintegration: Direkte Herstellung von Designflächen am Bauteil reduziert die Notwendigkeit von Verkleidungsteilen und senkt somit Kosten.
Präzise Oberflächen ohne Zerspanung: Hochpräzise Montageflächen ohne mechanische Bearbeitung im Bereich von 0,01mm.
Funktionale Integration: Bei einer max. Prozesstemperatur von ca. 50°C können Funktionen wie Kühlleitungen direkt eingegossen werden.
Höchste Steifigkeit: 3,5-mal höheres Steifigkeits-Gewichts-Verhältnis im Vergleich zu Grauguss, minimale elastische Verformung.
Positive CO2-Bilanz: Mineralguss (360 kg CO2e/t) schneidet deutlich umweltfreundlicher ab als Grauguss (1.650 kg CO2e/t).
