Precision manual 3jaw rotary platform available in 4 inch and 6 inch sizes. Designed for accurate rotary positioning, secure workholding, and easy integration into automation, robotic joints, and laboratory equipment. Features an MT2 center taper hole and Ugroove for versatile fixturing. Key benefits Precise rotary motion for accurate indexing and repeatable positioning during machining, inspection, or assembly. Manual operation and 3jaw clamping provide strong, reliable grip for round and irregular parts without complex control systems. Broad mounting compatibility: MT2 center taper hole, Ugroove, and a square mounting bar hole range accommodate common tooling and fixtures. Compact footprint and clear dimensional data make it straightforward to plan mounting and layout for integration into existing systems. Durable construction and well defined dimensions simplify selection for automation, robotic joints, or laboratory rotating stages. Main specifications (4 inch / 6 inch) Size: 4 inch / 6 inch Vertical height: 145 / 200 Base length: 114 / 160 Center height: 85.5 / 100 Horizontal height: 170 / 180 Square mounting bar holes: 110130 Ugroove width: 17 Ugroove depth: 10 MT2 center taper hole Bottom width: 68 / 78 Bottom length: 120 / 160 Number of jaws: 3 Power: Manual Net weight: 19 kg / 21 kg Important attributes Function: Manual rotary indexing and workholding for machining, inspection, assembly, and testing. Compatibility: MT2 center taper hole and Ugroove accept common center tools and fixturing. Square mounting bar hole range allows flexible mounting orientations. Size and footprint: Available in two sizes to match part size and machine capacity. Detailed bottom and base dimensions help ensure correct fit and clearance. Performance: Manual control with three jaws provides straightforward, stable clamping suitable for precision tasks where powered rotation is not required. Typical application scenarios Small part machining on milling machines: Mount the rotary platform on the machine table to perform indexing operations, circular cuts, and multiface machining with repeatable accuracy. Robotic joint or automation element: Use as a rotary stage in pick and place setups or inspection stations to provide controlled rotation and positioning for end effectors or workpieces. Laboratory and inspection equipment: Integrate into test rigs or rotating sample holders where controlled manual rotation and stable clamping are required. Installation and selection guidance Choose the 4 inch or 6 inch model based on part size and required center height. Check the base and bottom dimensions to confirm fit on your machine or fixture. Use the MT2 center taper hole for centers or tooling requiring a taper mount. Utilize the Ugroove and square mounting bar hole range for secure mounting and additional fixture options. Consider net weight for handling and mounting requirements; the platform is compact and suited to table mounting or integration into automated systems. This rotary platform is a practical solution for precise manual rotation and workholding in machining, automation, robotics, and laboratory applications.
