Bigger Waterjet Machines Meets Demand for Large-Scale Production
New System Spot Welds Nonferrous and Dissimilar Flat Materials
Omax Corp., Kent, WA, has expanded its line of Maxiem JetMachining Centers, for abrasive waterjet cutting, by introducing three larger machine sizes to meet the large-scale pro- duction needs of OEMs, metal service centers and fabricators. The new 2060 and 2080
The new SpotMeld system from Cold- water Machine Co, Coldwater, OH, report- edly enables spot welding of 1000- to 7000-series aluminum, magnesium, non- ferrous and dissimilar sheet materials, offering an alternative to single-point join- ing processes such as resistance spot welding, laser welding and riveting.
models cut work to 6 ft.-7 in. wide by 20 ft.-6 in. long and 27 ft.-2 in. long, respective- ly. The Model 3060 boasts a wider work envelope, ideal for machining a range of mate- rials and thicknesses, from metals and composites to glass and plastics. This machine features a Y-axis cutting travel of 10 ft.-2 in. and an X-axis cutting travel of 20 ft.-6 in.
SpotMeld, based on refill friction stir spot weld (RFSSW) technology, uses rota- tional friction to heat the materials along with pressure to forge the parts together using wear-resistant tooling. In practice, heat generates between the tool and material, creating a soft region. Pressure then yields a solid-state joint. In addition to its ability to join dissimilar and lightweight materials, benefits reportedly include
These JetMachining Centers also feature the Omax Intelli-Trax linear drive system that uses brushless servo motors, integrated servo drives and precision linear encoders to provide constant and continuous feedback on cutting-head position.
