Jergens Pyramid Risers Provide New Angle for CNC Machining
Jergens’ pyramid risers feature a 30-degree mounting surface to ensure clearance for spindle and cutting tool paths, enabling more machining per setup.
Jergens Inc.’s three- and four-sided pyramid risers 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, the pyramid risers feature a 30-degree mounting surface to ensure clearance for spindle and cutting tool paths, enabling more machining per setup.
These solutions offer three mounting options. Direct-to-table uses t-slots, a center pin and a timing key, and is secured using t-nuts and socket head cap screws (SHCS). Quick Locating System (QLS) mounts are designed to accurately locate and clamp the pyramid to a base element, such as a subplate, 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 are designed to mate with many top tooling choices including self-centering vises, dovetail vises and ER collet fixtures.
A non-woven porous material with a special coating enables vacuum chucks and tables to hold sheets of metal and other materials more effectively on CNC routing machines. The material, called Vilmill, is used as a substrate between the sheet or plate material to be machined and a suitable vacuum table or vacuum chuck where it is held securely in place by the vacuum.
Many job shops start in a garage with a used mill and a manual lathe. The owners of this Utah job shop took a different tack. Along the way to a very successful business, they've debunked a bunch of myths commonly held about job shops.
As demonstrated at this Cincinnati-area shop, machines that both mill and turn shine brightest when workpieces are massive.
