SEPTEMBER 10-15, 2018 McCormick Place, Chicago IL Here is a sampling of what will be on display at this year's show. 56 MoldMaking Technology —— AUGUST 2018 Product Focus Five-Axis Series Targets Tooling, Optics Mitsui Seiki (USA)'s Vertex Hybrid G series of five-axis VMCs (models 55-5X, 75-5X and 100-5X) offer high speed, lights-out milling and grinding of die and mold, optical, and tooling components. The machines are capable of 0.0003" (7.5 μm) precision in 3+2 or simultaneous five-axis machining, and their main spindles rotate as fasts as 25,000 rpm. Air spindles enabling speeds ranging from 40,000 to 90,000 rpm can be changed via ATC. FANUC 3D volumetric compensation features enable volumetric calibra- tion according to ISO10320-2 standards and the use of in-process 3D (NIST) traceable measuring capabilities. A part spinning process produces tangential planetary work spindle alignment, emulating the U-axis motion of jig grinding equipment. The machines can employ trochoidal dynamic power or high-speed cutting strategies for tools rotating as fast as 90,000 rpm. Key features include automatic, in-process grinding wheel dressing and size measurement and wheel calibration. Acoustic emission sensors and software- guided application strategies monitor milling and grinding process finishes. The VMCs feature cast iron beds and a solid "box-in-box" design that contribute to rigidity, stiffness and agility. Positioning accuracy is 0.001 mm (0.000040") in the X, Y, and Z axes, ± 6 arc seconds in the A axis, and ±4 arc seconds in the C axis. Hand-scraped guideways contribute to precision. A thermal compensa- tion system facilitates size consistency, and glass scales provide a minimum resolution of 0.001 mm. Mitsui Seiki (USA) Inc., South, Level 3, Booth 338519 September 10-15, 2018 / Chicago, IL Medium-Format AM Machine Reduces Downtime Trumpf Inc.'s TruPrint 3000 is a medium-format additive manufacturing machine geared towards the large-scale production of complex metal parts. The machine can make parts from a variety of weldable materials including steel, nickel-based alloys, titanium and aluminum. The machine uses laser metal fusion (LMF) technology and processes parts measuring as large as 300 mm in diameter and 400 mm tall. The laser's beam diameter measures between 100 and 500 microns. The system supports preheat temperatures ranging to 200°C. The TruPrint 3000 features exchangeable build and powder supply cylin- ders to enable quick change-over and reduce downtime to as little as 30 min. between build jobs, the company says. The exchangeable cylinders save opera- tors time by enabling them to prepare a new set of supply chambers or unpack a finished build outside of the machine in a separate unpacking station. The system is equipped with two 75-L supply cylinders that contain enough powder to complete an entire manufacturing process. Trumpf Inc., North, Level 3, Booth 236217 Redesigned Chucks Connect to Smartphones Via Bluetooth Erowa's SmartChucks line has been redesigned to combine precision and stabil- ity with wireless signal transmission. The design includes an integrated LED strip that displays the status of the chuck while in operation. It is able to indicate if the chuck is open, closed, improperly clamped or has insufficient clamping force. This functionality enables an operator to check the status at a glance. The company has also developed a mobile app that compliments the chucks, which is said to retrieve clamping equipment data on a smartphone. Status requests and additional information regarding the life-cycle can be checked at any time via Bluetooth technology. Erowa Technology Inc., East, Level 3, Booth 135037
