This Sucks, and that's GOOD
The FILTAIR MWX-S, from Miller Electric Mfg. Co., is a self-cleaning mobile fume extractor designed to reduce downtime and consumables costs in heavy-duty manufacturing and fabrication environments. Featuring a nanofiber filter designed to capture the submicron particles contained in welding fumes, the filter uses pulse-jet technology to restore filter life in one minute. Created for welding applications with high arc-on time and processes that produce large amounts of fumes, such as stick or flux-cored, the self-cleaning feature can pay for itself in eight cleaning cycles and reduces the chances that an operator will continue using the unit beyond its specified filter life. The nanofiber filters are surface loading, which means they last up to three times longer than depth-loading filters. The filter features 875-cfm extraction capacity. The arm is equipped with a bell-shaped hood for fume extraction. The FILTAIR is available with 7', 10', and 12' extraction arms.
"We are Family"
The family of DNM vertical machining centers are available in three sizes, with each size available as the DNM standard speed or as the high speed DNM HS. Powering the VMCs from Doosan are spindle motors ranging from 15 to 30 hp. Under test conditions, the VMCs removes 26.4 in3/min when face milling SM45C carbon steel, 42.2 in3 for GC25 gray casting, and 109 in3 for AL6061 aluminum. It has a ribbed, one-piece bed. Fine-grain Meehanite cast iron provides vibration absorption and thermal stability. The table is supported by the saddle in all positions, with no table overhang. All axes have linear motion guide ways. The DNM holds 5.4 roundness and Ra 0.12 roughness. Spindle rpm in the standard models top out at 8,000 rpm, with the high-speed versions reaching 15,000 rpm. High speed spindles are driven by a built-in motor generating up to 123 ft-lb torque. Linear motion guide ways and high speed servomotors produce rapid traverses of 1,890 ipm along all three axes of the DNM HS, and 1,717 ipm along the X and Y axis, and 1,181 ipm in the Z axis. Tool-to-tool time in the machines' 30-tool capacity is 1.3 seconds. The DNM vertical machining centers are available in three sizes: the DNM 400 with a 36.2"×17.1" table; the DNM 500 with a 47.2"l21.3" table; and the DNM 650 with a 51.2"×26.4" table. Each is available as standard speed with a Fanuc 0i controller, or as high speed with a Fanuc 32i controller. For Cutting Remarks
The PENTAC PLUS cutting system from Gleason is engineered to provide higher tool life and improved productivity, with cutters using multiple face blade geometry. An enhancement is the blade clamp block design for height and radial adjustments. The cutting systems is available for face hobbing and face milling in all cutter sizes and can be adapted to any existing Gleason gear cutting process without additional software or hardware requirements.
Micromachining for Macro Results
Newport Corp., introduced a micromachining workstation designed for laser direct-writing – LDW – and patterning. The device can be integrated with several lasers to produce 2- or 3-dimensional patterning and writing on almost any material. It can be coupled with continuous-wave, nanosecond, and femtosecond lasers. The workstation can be used to produce submicron resolution on large surface areas of the substrates. The micromachining workstation can be customized with different lasers to perform surface and volume patterning in semiconductors, dielectrics, and biocompatible materials. The workstation configuration includes precision linear stages which let laser direct-writing with sub-micron resolution. This solution is designed for prototyping of complex 2- and 3-dimensional microstructures in diverse fields such as photonics, microelectronics, and tissue engineering. The workstation uses standard optics, opto-mechanics, motorized motion, and up-to-date laser products. Its user-friendly interface lets the user create diverse patterns on many substrates and the intuitive software lets the researcher collect and analyze the data. A One-Two Punch
TRUMPF's TruPunch 5000 operates about 10 percent faster than its predecessor, with 1,400 strokes per minute for medium format and 1,200 strokes per minute for large format. This means 200 more strokes without using more energy. The TruPunch 5000 can process a maximum sheet thickness of 0.3". Two other ways in which the TruPunch 5000 is fast: It only takes 2.8 seconds to change tools, and only 0.3 seconds to change the tools within the MultiTool. As a result of weight-optimized components and tool cartridges, the X-axis accelerates to a maximum speed of 3,900 ipm or 65 ips. Another feature is the gantry drive of the Y-axis. Two separate motors are controlled synchronously without a mechanical connection. Working range – on the X- and Y-axis – is 100"×50" and 120"×65", respectively. Punching force is 25 tons and maximum simultaneous XY speed is 4,600 ipm. t: www.us.trumpf.com
