small bending head that facilitates the creation of close shapes in a single cycle, even for tubes that normally require two-way bending. The bending head also allows the simultaneous use of multiple types of tooling including different radii, compound clamps, and variable radius dies.
The head can be manually indexed for either clockwise or counterclockwise bending. An optional Tangent Boost device is available to axially push tubes during the bending process in the slide/ wiper die zone to minimize waste by reducing required cut lengths. Crippa 963LE and 980LE machines are pre- confi gured to be easily integrated into working cells. High production speed, ability to integrate special devices, and capability to create bends with a radius of less than 0.8D or push with variable radius bends (optional) make these ma- chines well suited for applications in the automotive, aerospace, urban design and shipbuilding industries. All nine machine axes are driven by electric motors with digital full-electric technology and controlled by the Siemens 840 D sl CNC; there are no hydraulics. An intuitive interface with a 19" (482-mm) color LCD touch screen features Crippa’s User ISO Interface (UII) software with full-cycle simulation and program optimization functions. The UII software may also be used for program- ming offl ine or remotely connected to the bender, and can extract data from solid models of parts. The combination of high production speed, the ability to integrate external processes, and capability to create bends with a radius of less than 1D or push with variable radius bends make these machines a suitable choice for the kind of aerospace products AMI and AWI produce. “Our customers typically require parts with complex bends for which OEM drawings no longer exist,” said Heid.
“Using our extensive reverse engineering expertise, AWI tech- nicians clone worn or damaged OEM parts using advanced CMM scanning technologies to create bending fi les that can

The New Grinding Edge
SMART-III technology is now available in a multi-functional two- or three-axes CNC surface grinder. The SMART’s PC-based control, combined with a user-friendly conversational TaskLink function, makes it easy to learn and operate. CNC experience is not necessary. The SMART control features a highly efficient, constant-contact auto dressing function and variable spindle speeds with constant surface speed control that reduces initial dress time from hours to minutes. All data transfer is simplified by using a USB data port or an Ethernet connection. The simulation mode is great for job shops, to prove-out a program prior to putting it in production, reducing or eliminating scrapped parts and simplifying part set-up. The table size is up to 24"W x 80"L with table loads up to 1,473 lbs.
