überchuck High Performance Milling Chucks

00 Years of Innovation For more than 00 years, the name lbrecht has been synonymous with innovation and quality. In 908, the Joseph lbrecht Bohrfutterfabrik GmbH & Co. was founded in Stuttgart, Germany, as a manufacturer of precision drill chucks. In 92, lbrecht developed the Classic Keyless Drill Chuck, a product that would become widely regarded by metalworking professionals as the most consistently accurate drill chuck available anywhere in the world. s manufacturing technology advanced over the years, lbrecht s engineers kept ahead of the curve continuously developing new products specifically designed to maximize machine tool performance. Today, lbrecht s most advanced product the überchuck High Performance Milling Chuck, is revolutionizing CNC machining. With unmatched accuracy, rigidity, and vibration-dampening capabilities, the lbrecht überchuck plays a key role in helping manufacturers squeeze every last drop of performance out of their machine tools.

HOW CN THE LBRECHT überchuck DO WHT OTHER TOOL HOLDERS CN T? Ultra-Precision ccuracy ll Überchuck Milling Chucks are guaranteed to run within 0.0002 TIR or better at 2. x diameter. High accuracy is important not only for part quality, but also because it ensures that cutting tools stay on centerline, distributing the chip load evenly and significantly extending tool life. Outstanding Rigidity and Dampening Carefully optimized expansion tolerances and unique vibration-dampening capabilities provide smoother part finishes and up to a 60% increase in cutting tool life. High-Speed Balanced ll Überchuck Milling Chucks are dynamically balanced to G2.@20,000 rpm for high speed operation. Versatile The Überchuck is available in multiple lengths and capacities to handle a wide range of applications. Interchangeable collets add to its flexibility. Thru-Coolant Ready ll Überchuck s are high-pressure rated to 400 psi. Sealed collets are available for thru-tool coolant delivery. Wide Gripping Range Model 4 /8 9/6 Model 20 /8 /4 Model 2 /4 -/4 Unique Collets proprietary surface coating enables easy loosening and fast collet changes. Collets are available in both inch and metric sizes and include a depth stop screw for precise length adjustment of the cutting tool. Fast, Easy Tool Changes Changing or adjusting a cutting tool in the Überchuck takes just a few seconds with the simple turn of a hex key. There are no costly induction heaters or hydraulic presses to hassle with. For an even better solution, see below. Foolproof Tightening Many Überchuck users purchase our specially designed torque wrench to ensure optimal and perfectly consistent tightening of the collet. The ergonomic handle, pre-set torque limiter, and full-power release mechanism takes all of the guesswork out of collet/tool changes. Simplify operations and maximize performance with the lbrecht Überchuck torque wrench. 8 TEL: -800-468-008 Fax: -800-4-92 www.albrechtchucks.com

Big Benefit # Incredible Gripping Torque The lbrecht Überchuck is a revolutionary tool holder that utilizes a patented two-stage clamping mechanism to produce extremely high gripping torque on the cutting tool. Gripping torque is the rotational force that acts against cutting tool slippage. Here s How It Works: Stage hex key rotates the worm, which drives a precision gear. The mechanical advantage achieved by this worm/gear assembly is much greater than that of a direct-drive system. Stage 2 specially coated slow-taper collet is threaded into the gear, so as the gear rotates the collet is pulled back into the body of the Überchuck. The angle between the collet and Überchuck body conforms to the Morse Taper standard, producing a near-perfect locking interface between the two components. The torque achieved through the combination of these two mechanisms is truly amazing significantly exceeding that of other commonly used systems. See graph below for test results.

Results You Can See The gripping torque of the Überchuck is so awesome, we designed and built a special display so potential customers would be able to experience its power firsthand. The display consists of a fixed CT-40 spindle rigidly mounted to a structural steel frame, which is then bolted to a heavy steel base. The CT-40 spindle holds a Model 2 Überchuck with a.2 diameter collet. To simulate a typical cutting tool, we manufactured a hardened and ground shaft with a.2 O.D. and a one-inch hex on one end. This cutting tool is gripped in the Überchuck, and a four-foot long torque wrench with a socket is used to engage the hex. The torque wrench is set to click at approximately 600 ft.-lbs. To experience the Überchuck s gripping power, a person stands on the base and applies downward pressure to the end of the torque wrench. Because of the long length of the wrench, most people are able to push down with enough force to achieve the full 600 ft.-lbs. of torque. To everyone s amazement, the torque wrench clicks at this point, yet there is absolutely zero slippage of the cutting tool in the collet. Experience the Incredible Gripping Torque of the lbrecht Überchuck Yourself Big Benefit #2 Longer Tool Life In independent testing, cutting tool life increased by as much as 60% when using the Überchuck (compared to shrink-fit and hydraulic chucks). The accuracy, rigidity, and vibration dampening capabilities of the lbrecht Überchuck enable the use of the latest, most aggressive cutting tools on the market.

Big Benefit # Excellent Rigidity & Vibration Dampening The performance of a tool holder depends upon both its rigidity and its ability to dampen vibration. The illustration below represents the results of an independent test comparing the maximum depth of cut that various holders were able to achieve up to the point where chatter began to occur. s the results show, the extreme rigidity and vibration dampening ability of the lbrecht Überchuck allows for much more aggressive cutting and optimal machine tool performance.

ÜBERCHUCK COLLETS ll Überchuck collets create a locking tapered fit with the holder. Their included angle is similar to that of the locking Morse Tapers found on live and dead centers. special surface coating on the collet increases wear-resistance and reduces friction, resulting in higher gripping torque while enabling fast, easy tool changes. deep throat and long, ground gripping surface produces superior accuracy and rigidity. Sealed collets are available for use with thru-coolant cutting tools*. überchuck sealed collets can be used with high pressure coolant systems up to 400 psi. n internal stop screw allows for precise presetting of the cutting tool length.
