Component Specifications

Definition
A fixture base plate is a fundamental structural component in automated fixture systems, engineered to provide a rigid, flat reference surface for mounting and securing workpieces, tooling elements, and modular fixture components during machining, assembly, or inspection operations. It ensures dimensional stability, repeatable positioning, and vibration damping.
Working Principle
The base plate operates by providing a precisely machined datum surface with standardized mounting patterns (like grid holes or T-slots). Workholding components attach to this surface, transferring clamping forces and maintaining alignment through the plate's rigidity, which minimizes deflection and maintains geometric accuracy under operational loads.
Materials
Typically made from high-strength cast iron (e.g., Grade 300), ductile iron, or stress-relieved steel (e.g., AISI 4140). May feature hardened surfaces or coatings like nickel plating for wear resistance and corrosion protection.
Technical Parameters
  • Hole Type Threaded (e.g., M12) or T-slots
  • Thickness 50-150mm
  • Load Capacity Up to 5000kg distributed
  • Standard Sizes 400x400mm to 1200x1200mm
  • Surface Finish Ra ≤ 1.6μm
  • Flatness Tolerance ≤0.02mm/m
  • Mounting Hole Pattern Grid spacing: 50mm or 100mm
Standards
ISO 8525, DIN 55027
