Multi-axis rotary laser
The FG-150, six-axis, 3D rotary laser cutting system from Mazak Nissho Iwai (Schaumburg, IL) automatically loads, feeds, laser cuts and unloads materials. The system offers unattended fabrication of round, square, rectangular and triangular pipe as well as I and H beams, C channel and angle iron. A 64-bit NC simultaneously controls the compact 3D cutting head and auto-fixturing rotary chuck, enabling the system to laser cut-in one operation-precise anble cuts, weld-prep bevels and advanced contours such as saddle joint cuts. A choice of three resonators, from 1500 to 4000 watts, enables fabricators to choose the power most efficient for their business.
The FGCAM software incorporates illustrated fill-in-the-blank screens to generate NC code, performs dynamic nesting and has more than 70 pre-programmed cut conditions. Fabricators also can control cuts and save frequently used cut condition set-ups.

Measuring and alignment system
Intended for precision measuring and machine alignment, the Microgage 2D from Pinpoint Laser Systems (Newburyport, MA) delivers a precision of 0.001 inch. Reportedly, it can be used for measuring in two axial directions at the same time, even when the distance between the laser and the receiver varies by 70 feet or more. The product consists of a laser transmitter that projects a beam of visible laser light and a compact, square receiver that is moved to various measuring areas and captures the laser light for the measurement.

Lytron Inc. (Woburn, MA) has improved features of its Kodiak recirculating chillers. The product's temperature stability is typically ±0.5 degrees Celsius, an average of 33 percent improvement, and the temperature stabilization time has been reduced five-fold, according to the manufacturer. Additionally, the response to a setpoint change is immediate. The company reports that the improvements result from changes to its proprietary Proportional Integral Derivative (PID) controller software.

The automated MicroLine 600 non-contact measurement system from Micro-Metric Inc. (San Jose, CA) provides depth and linewidth measurement for semiconductor wafers. It measures linewidths of 0.5 microns–.40 microns at 100x and 10 microns–800 microns at 5x. A hand-lapped X-Y stage with laser interferometer positional feedback provides better than 0.5-micron stage positional accuracy per four inches of travel. Line measurement repeatability is 2 nm. The product features a granite base and bridge with air-bearing Z axis. A confocal microscope provides precise focus detection for depth measurement repeatability of better than 20 nm.

New from Schneeberger Inc. (Bedford, MA), the Monorail BZ 35 connects highly accurate toothed gear segments creating a unified linear guide and rack that is ready for installation with a pinion drive. According to the company, the design allows for a high degree of accuracy in processing and positioning at high speeds and high accelerations as well as longer service life. Low friction and low stroke pulsation are achieved due to the optimized corner and bedding-down geometry. Additionally, a high degree of rigidity and large static and dynamic load-bearing capacity are achieved because of the four rows of ball bearings, a two-point contact and an o-shaped geometry with a trapezoidal track profile.
