Component Specifications

Definition
The Base Frame is a rigid structural component designed as the primary support structure for Ground Assembly Units in industrial machinery. It serves as the foundational element that distributes operational loads, maintains alignment of mounted components, and ensures overall machine stability during operation. Typically constructed from welded steel sections or cast iron, it incorporates precision-machined mounting surfaces, leveling provisions, and often includes integrated features for vibration damping and thermal expansion management.
Working Principle
The Base Frame operates on structural engineering principles to provide a stable, rigid platform. It transfers operational forces (static loads, dynamic vibrations, torque reactions) to the ground through its design, preventing deflection that could compromise machine accuracy. Its geometry and material properties are engineered to maintain dimensional stability under varying thermal conditions and mechanical stresses, ensuring consistent alignment of all mounted components throughout the machine's operational lifecycle.
Materials
Typically fabricated from structural steel (ASTM A36, S235JR, S355JR) or cast iron (Grade 250-350). High-precision applications may use stress-relieved steel or granite composites. Surface treatments include industrial painting (epoxy/polyurethane), galvanization, or powder coating for corrosion resistance. Welding follows AWS D1.1 standards with post-weld heat treatment where required.
Technical Parameters
  • Load Capacity 5,000-50,000 kg (depending on application)
  • Surface Finish Ra 3.2-6.3 μm for mounting surfaces
  • Natural Frequency >30 Hz to avoid resonance
  • Thermal Stability <0.05 mm/°C expansion coefficient
  • Flatness Tolerance ±0.1 mm/m²
Standards
ISO 230-1, DIN 8601, ISO 2768-mK, DIN 8570
