Cable management system
Robolase Solutions (Farmington, MI) introduces the E-Z Whip System for robotics, a cable management system providing a reliable, cost-effective solution for robotic Nd:YAG laser processing. The system is a complete package that includes TRUMPF and Rofin generators and utilizing standard beam and delivery fibers coupled with cutting or welding heads.
The system's spine is composed of a resilient material that gently twists and bends with the manipulation of the cutting or welding head, maintaining the minimum bend radius for cables and hoses. It is a robust, low-maintenance product that reduces Nd:YAG laser fiber optic cable breakage caused by robotic articulation and the additional mass to the fiber (cutting/welding heads, sensor cables, hoses). The system controls and manages cables, preventing them from hooking on robot wrist and tooling apparatus during manipulation.
Flexible manufacturing cell
Finn-Power International, Inc. (Schaumburg, IL) has introduced the LPE high-precision flexible manufacturing cell (FMC) that combines a 6-axis, servo-motor driven E5 turret punch press, the latest-generation CO2 laser, and an automatic loading, stacking, and unloading robot to provide punching, marking, tapping, nibbling, upforming, bending, and laser cutting, all in one machine.
The LPE is designed for high-precision applications and allows forming heights to 0.62 in., with forms made by the die moving upward and then retracting, allowing free sheet movement and eliminating scratched or jammed sheets. A robot loads, stacks, and unloads sheets and parts and places them in designated finished part locations.
Solder bonded optics
LaserPro (Walnut, CA) introduces the PermAlign™ solder bonded optics technology. Designed for use with the Laser Pro Stellar Mark I-series, the new technology features two optical lenses that reflect light inside the laser head to accumulate energy to emit laser light, thereby eliminating lens displacement from vibration. Each optical lens in the laser is aligned using precision tools and is permanently solder-bonded into position, fixing the optical components inside the laser on a firm, solid platform to avoid unnecessary downtime resulting from beam drifting and mode and power changing in the production line.

Laser nano sensor
LMI Technologies (USA) (Detroit) has introduced a high-speed, high-accuracy Laser Nano Sensor featuring a miniature sensor head and extremely small spot size for use in small work envelopes in high-tech industrial applications ranging from micropositioning to thickness and roughness measurement. The sensor uses auto-focus principles with a resolution as fine as 0.7 nanometer at speeds to 200 kHz, and boasts one of the fastest response rates in the industry as well as spot sizes ranging from 1-6 microns, allowing for displacement measurement within a few nano meters on quantifying surface roughness of any highly reflective surface that can be positioned perpendicular to the laser beam path.
Available in four standard models, the LNS sensor has a measuring range from 0.00016 to 0.005 in. and operating distances from 0.09 to 1.0 in. Accuracy ranges from 0.0022 to 0.75 nano meters, depending on the target.
The sensors operate in temperatures from 32–120° F and can be used in conjunction with various machines and robots, or can be custom-designed for OEM applications.

The Thomson Piloted RediMount™ innovative mounting system allows Thomson Slides to easily mount, horizontally, vertically, inclined, or inverted, to nearly any motor, with guaranteed alignment.
The Thomson Piloted RediMount™ eliminates the need to research, confirm fit, or specify interface dimensions between a positioning slide and the motor of choice. The slide part number and manufacturer and part number of the motor to be used are all that need to be specified, and the mating motor interface will be customized for a given frame size at no increase in lead time or price.
Smallest linear ball-screw stage
Aerotech's (Pittsburgh) new ATS125 series linear ball-screw stage is its smallest hardcover, side-sealed linear stage for high servo bandwidth and smooth velocity, reducing the overall footprint and enabling its deployment in space-constrained applications. Features include travel up to 600 mm, speeds to 600 mm/s, a side-seal design with hardcover, low cost/high performance, an integral brushless rotary motor, and standard and precision-grade options.
According to the company, coupling a brushless motor to the ball-screw eliminates the flexible coupling typically present in screw-driven stages, provides a stiffer system with higher servo bandwidth, and improves system reliability by removing a component susceptible to failure. The integral slotless motor, enclosed in a modular subassembly, provides ultra-smooth velocity due to the complete absence of torque ripple and can be easily replaced in the field.
