Component Specifications

Definition
A rigid structural component designed to provide a stable reference surface and mounting interface for securing workpieces during machining, assembly, or inspection processes. It ensures accurate positioning, repeatability, and vibration damping while maintaining dimensional stability under operational loads.
Working Principle
Utilizes mechanical clamping forces and precision locating features (pins, edges, surfaces) to immobilize workpieces against a reference plane, preventing movement during machining while maintaining accessibility for tooling.
Materials
High-strength aluminum alloy (e.g., 6061-T6, 7075-T6), hardened steel (AISI 4140/4340), cast iron, or composite materials with thermal stability and wear resistance
Technical Parameters
  • Load capacity 500-5000 kg depending on size/material
  • Surface hardness HRC 40-60 (steel variants)
  • Flatness tolerance ±0.01-0.05 mm/m
  • Standard grid pattern M8/M10 threaded holes at 25/50/100 mm spacing
  • Thermal expansion coefficient <23×10⁻⁶/K (stabilized variants)
Standards
ISO 8525, DIN 6319, ISO 10791-7

Frequently Asked Questions

What is the difference between a base plate and a fixture?

A base plate provides the foundational reference surface with standardized mounting features, while a fixture includes additional custom elements (clamps, locators) adapted for specific workpieces. Base plates are often modular components within fixture systems.

How do I select the right material for a base plate?

Consider machining forces (steel for heavy loads), thermal conditions (stabilized materials for temperature variations), weight requirements (aluminum for manual handling), and corrosion resistance (coatings or stainless variants).

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
