42 MoldMaking Technology —— DECEMBER 2018 Products: Most Viewed Products of 2018 Machines Feature Automation, Hybrid Capabilities and More Matsuura USA offers its MX-330 five-axis vertical machining center with 10 pallets and 90 tools, the tough and robust VX-660 vertical machining center and the new MX-520 five-axis vertical machining center with four pallets and 90 tools. In addition, the company offers the H.Plus-400 machining center with PC12. According to the company, the H.Plus series delivers long periods of reliable, unmanned operation, high accuracy and efficient production. Matsuura pairs the LF-160 linear motor machine with a robotic system to showcase the machine's high-speed, high-precision and high-accuracy capabilities. Matsuura developed the LF-160 for ultra-precision machining dies, molds and optical parts with a focus on small workpiece processing and unmanned operation. The LF-160's spindle achieves minimized dynamic runout and high resolution. Matsuura also offers the Matsuura Lumex Avance-25. The Matsuura Lumex Avance-25 metal laser-sintering, hybrid milling machine is a powder-bed metal additive manufacturing platform with subtractive machining capability. The Matsuura Lumex Avance-25 combines selective laser sintering with high speed milling. The series' Avance-25 relies on one-machine, one-process manufacturing of complex molds and parts by fusing metal laser sintering technology with high- speed milling technology. The Hybrid technology creates a "finished" part with a machined surface finish and with accuracy, without inducing the additional variation caused by multiple machine set-ups and part handling. The machine enables production of complex parts through total manufacturing by digital engineering using 3D data. The Matsuura Lumex Avance-25 achieves high accuracy in part fabrication because the metal powders are melted and sintered with a laser, while the surfaces are precisely milled at high speeds. Matsuura says that moldmakers can incorporate 3D cooling channels into molds in the single setup, thereby increasing cooling efficiency and enabling high-cycle injection molding with improved quality and precision. Matsuura / 651-289-9700 / matsuurausa.com 3D Printing with ABS Reduces Part Weight and Production Time Baker Industries' original equipment manufacturer customer was seeking a creative solution to reduce the weight of a traditionally machined aluminum mill fixture. Customarily, this fixture is used to hold parts in place during the trimming process. However, fixtures that are too heavy can result in compo- nent damage or destruction. By 3D printing the mill fixture using ABS thermoplastic material instead of machining it from aluminum, Baker Industries was able to reduce the tool's weight by 70 percent, which served to protect the parts that were being trimmed and provide a safer solution for employees handling the tool. In addition to reducing the weight, 3D printing the tool enabled the customer to save time on production. The team was able to print the tool in approximately fifty hours, which saved the customer a week of lead time that the customer normally would have needed to machine the tool. Because of the high-precision tolerances and the complexity required for this application, the change in approach did not significantly lower the cost, but instead was rather comparable. Overall, Baker Industries was able to offer the customer a lightweight solution that enhanced the mill fixture's function- ality and reduced the customer's lead time at a comparable cost. Baker / 586-286-4900 / bakerindustriesinc.com 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 / 800-552-3288 / makino.com
