Table Platform (Platen): Load Capacity 50kg to 5000kg

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.
