The TFG Ø250mm Tri-Riser is a compact, low-profile vertical workholding solution engineered to optimize part density on smaller 5-axis rotary tables and 4th-axis units. Featuring a space-saving 70mm height and a unique triple-face geometry, this riser allows for the simultaneous mounting of three System 52 fixtures (Ø16mm studs) while maintaining a low center of gravity for maximum stability during high-speed rotation. Crafted from aerospace-grade 7075 Aluminum to achieve a weight of 16.1kg, it delivers the perfect balance of structural rigidity and reduced moment of inertia, ensuring faster indexing and less wear on rotary drive systems. With a precision-ground finish providing ≤ 0.005mm repeatability, this riser is ideal for high-precision, high-volume production where maximizing spindle clearance and part-per-cycle count is essential in a confined work envelope.
