The VZ2 from Mitsubishi Laser division of MC Machinery Systems (Wood Dale, IL) features an offset head design that, according to the manufacturer, gives the machine more fabricating flexibility. Increased stroke and mounting weight enables greater workpiece versatility and size. This latest version of the company's three-dimensional VZ series also features software and programming enhancements that enable both 2D-to-3D and 3D-to-2D program conversion.

The offset head is compatible with tall and deep-formed workpieces. The rotation axis (C-axis) shifts from the processing point; thus, the workpiece does not interfere with the Z-axis. Reportedly, the non-electrostatic head eliminates the interference range, and the optional welding head expands the flexibility of the machine tool. The increased table mounting weight can hold up to 2000 Kg on the 3122 models. The LC20T control can convert from offset to zero-offset and also offers two-point-to-three-point arc conversion.

Laser processing systems

The JK401 and JK501 laser processing systems from GSI Lumonics Inc. (Farmington Hills, MI) are designed for industrial precision welding and high-speed cutting of metallic materials. The systems offer a combination of 400W or 500W peak power, beam quality and efficiency, which, the company says, is enhanced by its patent-pending laser power SuperModulation technology. SuperModulation momentarily doubles the laser's output intensity.

The World-Beam QS18LE Series laser emitters from Banner Engineering Corp. (Minneapolis, MN) are designed for use as a DC-power laser pointer in an industrial housing as well as the emitter half of an opposed mode sensor pair. Paired with a photoelectric receiver, the product is a cost-effective opposed mode sensing solution. The QS18LE's output is modulated to give the laser long life and keep the power band it emits accurate. As a pointer, the product provides five different beam shapes, including small spot, circle, vertical line, horizontal line and cross.
