The system includes a dedicated part holding nest that incorporates a vacuum to remove excess moisture and assist with holding the parts in place.


ven machines. In addition, it offers robot replacement parts including coils, mix heads and Rexroth pumps as well as parts refurbishing services. Alliance Automation recently unveiled its latest innovation,


a highly precise robotic waterjet trimming cell that integrates Yaskawa Motoman HP20D robots with ultra-high-pressure waterjet pump technology developed by Jet Edge Inc. (St. Michael, MN).


Significant Improvement Neither the auto industry nor Alliance is a stranger to


ultra-high-pressure waterjet technology. Robotic waterjets have been used for years to cut everything from the dashboard to the trunk panel and most parts in between. But Alliance’s latest generation of robotic waterjet trimming cells promise to significantly increase productivity and profits and improve worker safety. Armed with dual wall-mounted Motoman HP20D robots and Jet Edge’s 60 KSI (414.7 MPa) iP60-50 waterjet intensifier

pumps, Alliance’s new six-axis robotic waterjet trimming cell leads the industry in precision and dependability with Moto- man’s ±0.06-mm repeatability and Jet Edge’s reliable tie-rod intensifier design. Te cell’s sturdy, compact frame design allows stability to both the tool and robots to ensure consistent tight part tolerances. Te robotic waterjet trimming cell precisely cuts shaped


parts with many angles from a wide variety of materials, including carpeting, fiberglass, foam and plastic. According to Alliance Automation’s Steven Cranston, the


system has numerous automotive interior applications, includ- ing trimming headliners, dashboards, dash liners, bed liners, wheel liners, door panels, trunk trim, car carpet, and acoustic dampening components. It also can be used for similar appli- cations in the aerospace and marine industries, he added. “Our system’s wall mounted robots allow for the first two


axes to be mounted forward, over the part,” Cranston said. “Tis feature allows for a larger work envelope and motion to work easier around larger shaped parts. Te robots also are
