Explore the benefi ts of hyperMILL ® and switch to the CAM solution for all of your 2.5D, 3D, 5-axis, mill-turn, HSC and HPC requirements. © The helmet was programmed and produced by DAISHIN Vertical Machining Center Reduces Handwork in Complex Molds Makino's V90S is a next-generation vertical machining center (VMC) for five- axis continuous processing. This high-precision VMC evolved from Makino's three-axis Vi series and has an updated spindle and tilting and rotating axis unit that Makino says supports tighter tolerances and decreased machining and polishing times. The V90S combines quick machine movements and accu- racies with software for high-speed motion control. Makino says that the V90S is designed for high-speed finishing of multifaceted, 3D contours and that it cuts cycle times and reduces handwork in complex dies and molds. To maximize work-zone volume and load capacity, the V90S can accom- modate workpiece sizes up to 2200 x 1500 x 700 mm and weighing 5000 kg. Examples of such workpieces include the inner panels of automobile doors and front grilles. The X, Y and Z axes (2000 x 1300 x 800 mm, respectively) provide swift movements with rapid traverse rates of 58,000 mm/min and cutting feed rates of 40,000 mm/min. The V90S's A axis tilts at ±30°, which is wide enough to machine holes for an angular pin, while the C axis rotates at ±60°, ensur- ing that the tool tip can be positioned to provide optimum contact with the workpiece. Makino says that this extends tool life, provides the required surface finish and minimizes post-machining hand processes. Makino, South, Level 3, Booth 338700 Diamond-Tipped Tools Cut Sintered Carbide Horn USA's CVD-D-tipped tools are designed for drilling, turning and mill- ing carbide in the sintered state, ranging to a hardness of 2,200 Vickers. Depending on the application, the geometrically defined cutting edges range from extremely sharp and rounded to positive and negative chamfers. With application-specific cutting edge optimization, CVD-D diamond can be useful for roughing work or fine finishing. According to the company, the tools enable accurate profile machin- ing in the micron range. In terms of roughness, polishability and corrosion behavior, the surface structure is reportedly comparable to grinding and eroding processes. Horn USA Inc., West, Level 3 & Annex, Booth 431722
