Base/Housing: Surface Finish Ra 1.6 μm or better

Component Specifications

Definition

The base/housing is the foundational structural component of a rotary indexing stage, engineered to provide rigid support, precise alignment of rotating elements, and environmental protection for internal mechanisms. It ensures dimensional stability under operational loads, maintains geometric accuracy of the indexing system, and serves as the mounting interface for the entire assembly within automated machinery.

Working Principle

Functions as a static structural frame that absorbs and distributes mechanical forces (torque, vibration, axial/radial loads) while maintaining precise geometric relationships between mounted components. It provides a stable reference plane for the rotary axis and protects sensitive internal parts from contamination and physical damage.

Materials

Typically aluminum alloys (e.g., 6061-T6, 7075-T6) for lightweight rigidity, cast iron for high-damping applications, or stainless steel (304, 316) for corrosive environments. May include hardened steel inserts at wear points.

Frequently Asked Questions

What are the critical tolerances for a rotary indexing stage base/housing?

Flatness (typically ≤0.01 mm/100 mm), perpendicularity between mounting surfaces, and positional accuracy of mounting holes are most critical to ensure proper alignment and smooth indexing operation.

How does material selection affect base/housing performance?

Aluminum offers light weight and good machinability, cast iron provides superior vibration damping, and stainless steel resists corrosion. Material choice impacts stiffness, thermal stability, and durability in specific environments.
