Arnold Laser Technology

Provided by German Machine Tools of America (GMTA), the Arnold laser technology from Ravensburg, Germany, is now offered to the GMTA customer base in gearmaking, automotive powertrain, off-highway and other high-performance markets. New machines are offered, along with full laser integration technology through application engineering in the GMTA's Ann Arbor offices.

The newest additions to the Arnold laser line include a compact cell laser used for welding smaller, round components. Available with CO2 or solid-state lasers, this cell is suitable for mass production or smaller batches, owing to the onboard loading and enhanced CNC programming capabilities of the machine. Workpieces are loaded into the rotary carousel, either manually or by robotic automation available from GMTA. The workpiece is then lifted into position, clamped, rotated in the C-axis and laser welded. A new workpiece is loaded during the clamp/weld phase.

Also offered by GMTA is the Arnold 2-station laser cell, which is used in a similar fashion to the compact cell, but offers a variety of geometries in the laser welding, including axial and radial seams, plus an integrated pressing function. The processing optics move on a cantilevered arm to the individual work stations, processing radial or axial seams without changeover of the swiveling optic head.

Independent loading area gates allow simultaneous loading and unloading while the machine is in operation. All functions on the machine are run by CNC and the machine is designed as a single-block concept with a common base frame for all system components.
