Fixtureworks introduces its lineup of ultra-low-profile TriGrip carbide gripper inserts and TriMax vises.

TriGrip carbide gripper inserts are designed for ultra-low-profile, 0.14" (3.5-mm) clamping with no dovetail workpiece preparation. The triangular grippers feature two rows of teeth at different angles with a 5-degree taper to maximize the pull-down effect, divide the clamping force, absorb vibration, and provide high stability and secure workholding. Already integrated with the TriMax line of vises, the TriGrip inserts are ideal for upgrading existing vise jaws and more, the company says.

With only 3.5 mm of clamping surface needed to securely hold the workpiece, TriGrip workholding inserts are suitable for five-axis machining operations. The durable inserts combine a tough-coated cemented carbide with specialized teeth and triangular shapes that penetrate materials including steel, hardened steel/titanium (up to 50-54 HRC) and aluminum. The inserts eliminate the need for pre-machining or dovetailing workpieces and offer vibration damping.

The TriMax production vises to which the workholding inserts attach are available in several models. The TriMax G vise is designed for precision five-axis milling operations and can hold workpieces ranging to 7.87" (200 mm) in length, enabling five-sided access in a single clamping. Designed to hold as many as four workpieces at a time, the TriMax C vise is a modular system with movable jaws that can be positioned along the vise body to handle a wide range of workpieces. The TriMax T vise is a complete multi-part clamping system. Improving on the standard machinist vise, the TriMax M system maximizes workholding combinations with a design that enables quick and easy repositioning of the clamping jaws and “snap-in" change of parallels, soft jaws and V jaws.
