Product Focus 78 MoldMaking Technology —— AUGUST 2018 3D Printer Can Run for a Week Hands-Free Sodick's large-capacity OPM350L metal 3D printer/CNC machining hybrid expands the usable work area over its OPM250L model, and introduces the Material Recovery System (MRS) unit. With the MRS unit in place, the printer can run for a week without any human intervention, the company says, con- suming just 30 kg of metal powder. The machine and the MRS unit enable manufacturers to 3D print metal parts nearly 14" in the X, Y and Z axes and machine these surfaces to below 9 root square mean in one setup. With an in-process correction system, the printer can recover from would-be build failures without operator intervention. Sodick Inc., East, Level 3, Booth 134802 End Mills Achieve Greater Depth of Cut in Aluminum RobbJack's FMHV two- and three-flute end mills are designed for high- horsepower, high-velocity aluminum aerospace machining. The company says its Mirror edge geometry progressively reduces vibration at greater Z-depths of cut. Anti-pullout shank technology prevents tools from pulling out of the holder. Well-suited for high-speed machining of deep pockets and thin walls, the tools are available with through-coolant holes and a DLC coating that extends tool life in roughing applications. Overall length and reach length are designed to maximize gripping force in tight-tolerance toolholders. The company reports that a 1" diameter, three-flute FMHV with through-coolant holes and DLC coating can achieve a peak metal-removal rate of 713 ipm3 (72 lbs of 7075 aluminum per min.). RobbJack Corp., West, Level 3 & Annex, Booth 432079 Insert Drill's Redesign Improves Chip Control Seco Tools LLC will spotlight its redesigned Perfomax indexable insert drill. Designed for more aggressive drilling parameters as well as improved chip control and evacu- ation, the drill's flutes have updated helix angles and smoother chip flute exits. An engineered wave pattern reduces contact between chips and flute surfaces. The fronts of the Perfomax's flutes have been hardened with a laser to prolong tool life. A hardness of HRC 60 enables the drill to withstand chip erosion for longer periods of time. Perfomax drill bodies are available in diameters ranging from 0.594" to 2.375" (15 to 59 mm); in length-to-diameter ratios of 2×D, 3×D, 4×D and 5×D; and in most spindle interfaces. Seco Tools LLC, West, Level 3 & Annex, Booth 431564 MORE IMTS 2018 PRODUCTS TO COME Check out the IMTS 2018 Exhibitor Product Showcase in the September issue for more of what will be on display at the show.
