Tsugami Automation's new Tsugami CNC Swiss Turn, the SS207-5AX LaserSwiss, is a 20 mm, 7-axis CNC Swiss Lathe with two fully integrated SPI lasers, one for cutting and one for welding. The machine is the latest model in the company's LaserSwiss product line, and the first to include a second laser head for welding.

"The addition of the second laser head for welding is huge," Tsugami Automation Business Development Director Dan Walker said. "Users can now essentially replace three machines with one and perform very complex, dissimilar operations with a single setup. The range of capabilities this machine offers is unprecedented."

For example, Walker noted, the laser welding head not only allows users to weld two pieces together, then machine them, it allows operators to reflow a swaged tube end.

The laser cutting and welding heads can be mounted on either the X/1, Y/1 or B axes, and all operations are programmed and driven from the machine's FANUC 32i-B control. The nozzle standoff adjustment is also NC-controlled, and each laser's frequency, pulse width, focus and power are all on-the-fly adjustable and programmed through the machine's control.

Users can also adjust the assist gas pressure from 5 to 350 psi, allowing different pressures to be used for piercing and cutting, as well as the very low gas pressures typically used in welding. Wattage on the lasers can range from 20 to 750, depending on the customer's preference.

"As soon as I mention that our new LaserSwiss has welding capabilities," Walker said, "Everyone says it's a game changer."
