Mounting Surface Plate: Load capacity 50-500 kg/m²

Component Specifications

Definition

A precision-ground flat reference surface plate used as a mounting foundation for components in industrial machinery, providing dimensional stability, vibration damping, and accurate alignment for attached parts. Manufactured to tight tolerances with specific surface finish requirements to ensure proper mounting and operation of precision components.

Working Principle

Provides a stable, flat reference plane that serves as a datum for mounting other components. The precisely machined surface ensures components are mounted in correct spatial relationships, while the plate's mass and material properties dampen vibrations and maintain dimensional stability under operational loads.

Materials

Cast iron (GGG-40/50), steel (S355JR), or aluminum alloy (EN AW-6082 T6) with surface hardening or coating treatments. Material selection depends on required stiffness, weight, corrosion resistance, and thermal expansion characteristics.
