Three- and Four-Sided Pyramid Risers

Pyramid Risers Feature a 30-Degree Mounting Surface

Jergens Inc. announces its new three- and four-sided pyramid risers that permit multi part load and provide greater access for five axis machining applications. Part of the Fixture-Pro® line of quick-change modular workholding solutions, Jergens pyramids 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). 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 96mm pattern) to locate and clamp in a single step. 

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

Related Glossary Terms

  • centers

    centers

    Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.

  • clearance

    clearance

    Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.

  • collet

    collet

    Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
