Component Specifications

Definition
The Table Platform (Platen) is a critical structural component of rotary tables, engineered to deliver a rigid, flat reference surface for mounting and securing workpieces. It ensures dimensional stability and positional accuracy during rotational movements in machining processes like milling, drilling, and grinding. Typically integrated with T-slots, bolt patterns, or clamping systems, it facilitates secure fixturing and alignment of parts across various industrial applications.
Working Principle
Operates by providing a stable, level mounting surface that rotates with the rotary table's axis. It maintains perpendicularity and flatness to the rotational axis, ensuring workpieces remain precisely positioned during indexing or continuous rotation. The platform's rigidity minimizes deflection under cutting forces, while its surface features (like T-slots) allow flexible clamping arrangements.
Materials
Commonly manufactured from high-strength cast iron (e.g., Grade 250 or 300), ductile iron, or precision-machined steel (e.g., AISI 1045). May feature hardened surfaces or coatings (like nitriding or chrome plating) for wear resistance. Some applications use aluminum alloys (e.g., 6061-T6) for lightweight requirements.
Technical Parameters
  • T-slot Size 12mm, 14mm, or 18mm standard
  • Load Capacity 50kg to 5000kg
  • Diameter Range 200mm to 2000mm
  • Mounting Holes M8 to M20 threaded patterns
  • Surface Finish Ra 1.6μm to 3.2μm
  • Flatness Tolerance ±0.01mm to ±0.05mm per 300mm
Standards
ISO 10791-6, DIN 55027, ISO 230-1
