Laser System for Rapid Prototyping
The RapidX250 laser micromachining system can be used in rapid prototyping applications to fabricate microfluidic devices, microelectromechanical systems (MEMS), and medical devices with tolerances approaching 1 µm. Offered by Resonetics LLC, the system employs a multiwavelength 193/248-nm excimer laser to fabricate MEMs directly in a single step. As a result, MEMS fabrication can be accomplished in much less time than it would take to prototype such devices via traditional multistep semiconductor lithography processes, according to the company. The flexible system is able to microfabricate both 2-D sheets and tubes and 3-D parts, including in x-y-z, theta, and goniometer motion coordinate systems. At 193-nm, the laser can cleanly ablate fluoropolymers, bioabsorbable polymers, and glass. The system’s quick-exchange function lets the user easily switch to the 248-nm laser wavelength for machining polymers, ceramics, and metals. The user-friendly micromachining system also has a DXF file–to-CNC converter that facilitates conversion of concepts into prototypes.
Diode Laser System
Available from Dilas Industrial Laser Systems, the Compact fiber-coupled turnkey diode laser system based on an integrated diode laser module offers an optical output power of 30 W continuous-wave and enhanced beam quality. This direct diode laser system can handle challenging applications in materials processing owing to the very small focal diameters that can be attained; the beam parameter product is ±11 mm mrad, derived from a 100-µm fiber core diameter and a numerical aperture of 0.22. Focal diameters of less than 180 µm with fixed optics and less than 400 µm when a galvo scanner is employed can be obtained. Used in combination with the manufacturer’s standardized processing heads, the system can perform microscale plastics welding and selective microsoldering, processes that are becoming increasingly important in medical device manufacturing operations. The standard package comes with a fiber cable and focusing head.

New features are available for the Infinite Web all-in-one coil joiner, a system that incorporates automatic laser cutting and welding into a single head and uses a noncontact process for splicing coils. Joining Technologies Inc. has given the system the ability to splice titanium coils and to splice on a 15° bias as an alternative to forming perpendicular joints. Requiring only an electrical input and minimal operator involvement, the safe, user-friendly coil-joining system is a mobile stand-alone machine that can serve multiple converting lines, automatically preparing coil ends and delivering precision welds in cycles of fewer than 3 minutes. Its industrial PC–based control system features a touch screen interface, predefined programs for selected alloys, and proprietary self-diagnostics to maximize uptime. Designed by welders to handle material thicknesses of 0.002 to 0.040 in., the system employs coaxial optics to verify proper positioning and provide precise, accurate splices.

Laser Cutting System Accessory
The designers’ turnkey digital print-to-laser cutting system from Spartanics enables designers of medical devices, printed packaging and labels, faceplates and nameplates, and other laser-cut digital printing products to direct and control all print and laser-cutting finishing specifications at the earliest design stages. Unlike digital laser-cutting lines that require vector-based files to be input during setup, the print-to-laser cutting system allows product developers to use raster-image-processing software at the prepress level to specify not only print files but also laser-cutting files for finishing the product. It features the built-in capacity to extract the vector data embedded in PDF, ONYX, and other formats. In addition, the system allows the use of bar codes to signal job changeovers. This capability enables continuous production and cost-efficiency even with short-run jobs.

Automatic Tubing Coilers
High-performance tubing coilers in the Automatic Cut & Transfer series from Tulsa Power incorporate a dual-spindle-turret winder designed to wind tubing 0.032 to 0.625 in. in diameter in-line as part of an extrusion process. The fully automatic systems are equipped to coil or spool. They also have a cut-and-transfer feature that, upon receipt of a signal from the total-length counter, quickly cuts, clamps, and transfers products from the full reel to the empty reel without process interruption at speeds to 1000 ft/min. An ultrasonic dancer locates the position of the product without making contact and ensures smooth, tension-controlled winding of even very sensitive products. Allowing one operator to manage several extrusion lines, the coilers can reduce labor requirements. Their controls allow for reliable switchovers at high speeds.
Hydraulic Work-Holding Components
Used for clamping workpieces in high-production machining environments, a range of hydraulic swing clamps, valves, and pumps is available from Kurt Manufacturing Co. The clamps and accessory options enable manufacturers to configure the optimal work-holding system for a single machining center or for a multipallet manufacturing cell containing multiple machines. Providing 475 to 6000 lb of clamping force with a maximum pressure of 5000 psi, the single-cylinder components swing and clamp in one continuous motion; directional change of their motion is easily effected via a push-pull feature. The manufacturer’s compact, easy-mounting hydraulic pump is the power source for the work-holding clamps. It offers a peak total capacity of 127 cu in. and a usable capacity of 75 cu in.

High-Efficiency Diode Laser
The compact, modular LIMO1300-F200-SL808/9xx-EX1472 1.3-kW diode laser from Limo Lissotschenko Mikrooptik GmbH, designed for cutting and welding applications, has a wall-plug efficiency of 30%, including cooling, which compares favorably with other laser systems in its power class. This performance is attributable to the efficient fiber coupling made possible by high-end beam shaping. In addition, the passive cooling technology that dispenses with microchannels makes the system practically maintenance free. The easy-to-integrate laser can be used for thermal conduction welding and deep penetration welding of metals; it also serves as an alternative for laser fusion cutting of stainless steel, aluminum, and titanium and for laser frame cutting of structural steel and copper. The diode module is easy to replace, and the system employs standard process heads and beam-delivery systems.

Mandrel Straightening Machine
Relying on an automated straightening process, the MS700S mandrel straightening machine recycles bent or bowed catheter- and tube-processing mandrels that otherwise might have to be thrown away. Employed by Machine Solutions Inc. to minimize assembly material costs, this mandrel straightener allows damaged mandrels to be reused, extending their lifetime and reducing the consumption of resources. It utilizes a pick-and-place handling system capable of picking a single mandrel from a bin and automatically running it through the straightening process, after which it is placed in the output tube upon process completion. The cleanroom-compatible straightener has been configured to accommodate bare and coated stainless-steel mandrels of various diameters and lengths, and it does not have to undergo tooling changes.
