110 MMS March 2017 mmsonline.com TOOLING AND WORKHOLDING Fixtureworks introduces its lineup of ultra-low- p r o f i l e Tr i G r i p c a r b i d e g r i p p e r i n s e r t s a n d 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 workhold- ing inserts are suitable for five-axis machining o p e r ati o n s. T h e d u r a b l e i n s e r ts c o m b i n e a WORKHOLDING SYSTEM ELIMINATES THE NEED TO PRE-MACHINE WORKPIECES E D ITO R J E D D CO LE , jc o l e @ m m s o n l i n e.c o m tough-coated cemented carbide with specialized teeth and triangular shapes that penetrate mate- rials including steel, hardened steel/titanium (up to 50 to 54 HRC) and aluminum. The inser ts eliminate the need for pre-machining or dovetail- ing workpieces and offer vibration damping. The TriMa x production vises to which the workholding inserts attach are available in several models. The TriMax G vise is designed for preci- sion five-a xis 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 clamp- ing system. Improving on the standard machinist vise, the TriMax M system maximizes workhold- ing combinations with a design that enables quick and easy repositioning of the clamping jaws and "snap-in" change of parallels, sof t jaws and V jaws.

MILLING TOOLS GET UPDATE FOR MACHINING DEEP POCKETS IN TITANIUM Sandvik Coromant's CoroMill 390 is now available with the company's Silent Tools technology for more efficient machining of parts such as engine mounts as well as deep pockets on titanium-frame parts for the aerospace industry. Pockets are the most common feature in titanium structural parts for aircraft, often featuring depths of more than
