Exsys Tool highlights tooling systems
The Preci-Flex toolholder is for lathe tooling changeovers. It has a single base holder and multiple tooling adapters that utilize the ER collet pocket.
Exsys Tool Inc., San Antonio, Fla., displayed a variety of tooling system innovations for turning centers. Products highlighted included the Preci-Flex modular toolholder; specialized tooling, such as a gear hobbing system; and Double Square Shank and Quad Square Shank static toolholders.
The Preci-Flex system is a fast and accurate solution for lathe tooling changeovers, according to the company. It has a single base holder and multiple tooling adapters, which utilize the ER collet pocket. The compact design assures maximum torque transmission and rigidity. Available in a range of sizes, the toolholders offer repeatability within 5µm and allow for the interchanging of tooling adapters between fixed and rotary base holders.
IMTS attendees also discovered a compact gear hobber system that allows shops to generate splines, spur or helical gears in one operation. As an adjustable toolholding system, it eliminates having to rough gears on one machine and then transfer them to another for hobbing. Built for heavy machining loads, the gear hobbing system delivers 45 Nm of torque and speeds of up to 3,000 rpm for hobs or slotting saws up to 2.48" (63mm) in diameter.
Also, the Double Square Shank and Quad Square Shank static specialized toolholders, designed to increase tool turret capacity, accept two or four inserts, as opposed to just one, in a single tool turret station. With multiple-insert capability, different types of inserts can be located in the same station.
