- Jergens Workholding
In 1942, Jergens Inc. opened its doors and began its journey to grow into one of the world’s largest manufacturers of standard tooling components, vises and other workholding equipment. Since their founding Jergens, Inc. has grown to comprise 3 distinct business units: Workholding Solutions, Lifting Solutions and Specialty Fasteners. Building on its reputation of uncompromising quality standards, Jergens is committed to helping its customers achieve leaner, more profitable manufacturing, and continues to add products and engineered solutions for an integrated approach to “Manufacturing Efficiency.”
The 5CV 130mm self-centering vise features clamping forces up to 3,600 lb and offers important advantages for five axis machining applications. Among those are the reduction of jaw lift that can occur due to flex that allows the workpiece to raise up during the clamping process. To combat this errant force, the vise jaws have been engineered with a pull-down design to ensure clamping and minimize lift.
Quick-change jaws can be swapped out by the operator with no tools required. The unique vise can also be easily recentered along an adjustable centerline. Different mounting options are accounted for as well, to suit personal preference and current setup parameters. Those options include Jergens QLS, and Quick-Loc as well as Lang Quick Point and 5th Axis RockLock, both in 52mm and 96mm standard patterns.
The vise comes standard with step jaws that feature serrated inserts, however alternate jaw styles can be ordered following basic nomenclature to specify aluminum soft jaws, steel soft jaws, or hardened step jaws. Additional jaw sets can be purchased separately.
Jergens has developed cast iron tooling columns for horizontal machining to provide maximum rigidity by using a single-piece, cast-iron construction. Several mounting options are possible including direct, with a centre pin locating or edge locating, and also quick-change applications via ZPS with K20 pull studs and four-module subplate.
Column styles include square, cross, and rectangular. The square and cross styles are suitable for high-density, multipart fixtures or incorporating multiple operations into a single column.
The cross style allows better spindle access near the column, eliminating the need for extra-long tools. The larger upright faces of the rectangular columns are suitable for applications involving larger workpieces.
Column construction uses stress relieved, class 40 cast iron, with the base and sides milled flat, perpendicular, and parallel within 0.001 in./ft. providing an accurate foundation on which to set up workholding devices or quick-change systems.
Other features include a centre-locating bore, inch and metric hole patterns, and M12 lifting holes for secure hoist ring attachment.
Jergens Ball Lock® Mounting System continues to be the standard for performance & quality in quick-change mounting and fixturing.
Ball Lock® provides a proven method to quickly and accurately locate and lock fixtures onto machine tables and subplates. It is the single most cost-efficient and versatile fixturing system for horizontal and vertical machining centers.
