Jergens Pyramid Risers Enable Multipart Loads for Five-Axis Machining

Jergens’ three- and four-sided pyramid risers permit multipart loads and provide greater access for five-axis machining applications. The pyramids are part of Jergens’ Fixture-Pro line of quick-change modular workholding solutions and feature a 30-degree mounting surface to ensure maximum clearance for spindle and cutting tool paths, resulting in more machining per setup.

The engineered solutions offer three versatile mounting options. Direct-to-table uses t-slots, center pin and timing key, and is secured using t-nuts and socket head cap screws (SHCS). A quick locating system (QLS) accurately locates and clamps the pyramid to a base element (such as subplates) using a combination of QLS shoulder screws and SHCS. Quick-Loc pallet systems use pull studs (spaced at the industry-standard 96-mm pattern) to locate and clamp in a single step.

The lightweight aluminum risers are compatible with virtually all five-axis CNC machining centers and ensure fast changeover and setup times. Available in both three-position and four-position configurations, the pyramid risers mate with many top tooling choices, including self-centering vises, dovetail vises and ER collet fixtures.
