The TFG Ø350mm Quad Riser is a high-capacity vertical workholding solution engineered for large-scale 5-axis rotary tables and heavy-duty production environments. By utilizing a 90° four-face geometry, this riser allows you to mount four independent System 52 fixtures simultaneously, significantly increasing your parts-per-cycle over traditional dual-face setups. Constructed from aerospace-grade 7075 Aluminum to maintain a manageable 22.5kg weight, it provides the structural mass needed for heavy milling while minimizing the centrifugal load on your machine’s rotary axis. With a precision-ground finish ensuring ≤ 0.005mm repeatability, this 100.5mm high quad-tombstone is the ideal choice for high-volume manufacturing where maximizing table real estate and achieving total spindle access to multiple workpieces is critical for operational efficiency.
