Component Specifications

Definition
The Main Structure/Body is the foundational component of a cutterhead machine, engineered to withstand operational forces, vibrations, and loads. It serves as the primary load-bearing framework that houses and aligns the spindle assembly, drive systems, tool holders, and control mechanisms. Its design ensures dimensional stability, precision alignment, and structural integrity during high-speed cutting operations.
Working Principle
Provides a rigid, stable platform that absorbs and distributes cutting forces, vibrations, and thermal expansions. It maintains precise geometric relationships between moving parts to ensure cutting accuracy and repeatability. The structure's damping characteristics minimize resonance and vibration transfer to critical components.
Materials
High-grade cast iron (GGG-40/GGG-50), welded steel construction (S355JR/ST52-3), or polymer concrete composites. Materials selected for high stiffness-to-weight ratio, vibration damping properties, thermal stability, and corrosion resistance.
Technical Parameters
  • Damping Ratio >0.05
  • Weight Capacity 500-5000 kg
  • Static Stiffness >50 N/μm
  • Surface Flatness 0.02 mm/m²
  • Natural Frequency >80 Hz
  • Thermal Stability <0.01 mm/°C
Standards
ISO 230-1, ISO 10791, DIN 8601, DIN 8602
