Fixtureworks® (Fraser, MI) a leading North American manufacturer and supplier of clamps, fixturing accessories, machine tool components and rollers & bumpers, now offers a line of low-profile inserts called GripSerts.
These grippers are made to grip steel workpieces. With only 3.5 mm of clamp surface needed to securely hold the workpiece, TG GripSerts workholding grippers are ideal for 5-axis machining operations. Because of the geometry of the grippers, the inserts create a pull-down effect that prevents any lifting of the workpiece while clamping. These durable inserts combine a tough-coated cemented carbide with specialized teeth and triangular shapes that are uniquely designed to penetrate steel.
TG GripSerts workholding inserts offer many advantages over traditional clamping systems. Their special triangular shape with a 5° tapering and teeth geometry combine to provide exceptional clamping stability with no need for pre-machining or dovetailing workpieces. They are designed to absorb and dampen vibrations, providing secure and stable holding at lower clamping forces which prevents deformation of the workpiece. This results in a higher cutting rate and less waste of materials than traditional clamping systems. TG GripSert carbide gripper inserts are designed for ultra-low profile 0.14 in. (3.25 mm).
With only 3.5mm of clamp surface needed to securely hold the workpiece, TG GripSert
workholding inserts are ideal for 5-axis machining operations. These durable inserts can penetrate materials including steel, hardened steel/titanium (up to 50-54 HRC) as well as aluminum.
A retrofit GripSerts vise jaw kit is available, including jaw pair, wrench, and screw pack for a Kurt 6" vise. TG GripSert grippers and jaws can also be used with all TriMax Series vises. Using the TG-CUTTER tool to finish pre-machined insert seats, you can also install GripSerts on any custom jaws or clamping devices. The suggested clamping force is 30 ft.lb. For correct clamping, make sure to use the proper screw length for your specific vise. Proper length is determined by adding the thickness of the TG GripSert jaws and the depth of the thread of your vise.
Accessories are also available such as the exclusive Snap-in parallels, available in various heights and sold in pairs. The self-locking design of the parallels allows for the quick and easy installation on the TG GripSert jaws with no additional tools, and the aluminum protective covers (TG-PRO) in the empty pockets that keep out dirt and debris.
