Product Focus 76 MoldMaking Technology —— AUGUST 2018 IMTS Booth #134802, EAST Sept. 10th - 15th, 2018 (847) 310 9000 MoldMaker's Choice Simple Programming Flushing-Free EDM Zero-Wear Linear Drives Double-Column Machines Combine Speed, Stability The latest additions to Hurco's BXi CNC machine series are the BX50i, with X-, Y- and Z-axis travels mea- suring 37.4" x 53.2" x 23.6", and the BX60i, with X-, Y- and Z-axis travels measuring 52.1" x 63" x 27.6". The rigidity and thermal stability of the double-column design, combined with the weight of the machines, provide accuracy and improved surface-finish capabilities. Designed for the moldmaking and aerospace industries, the machines are suitable for high-speed machining applications that require tight tolerances. The double-column design is said to minimize machine distortion and thermal deformation. Also contributing to rigidity is a ladder-style bridge. This design supports the head casting, keeps the spindle centerline close to the supporting struc- ture and isolates the bridge from part weight. The machines feature integrated WinMax con- trol software and the UltiMotion motion system. The control software supports multiple program- ming methods, including conversational program- ming, NC programming and a Hurco-specific fea- ture called NC/Conversational Merge. The UltiMotion system is designed to determine the tool's optimal trajectory, ensure consistent programmed feed rates and reduce cycle time. Compared to conventional systems, it is said to improve cornering velocity and reduce machine jerk. It includes up to 10,000 blocks of dynamic look ahead and adapts to toolpaths. It improves on CAM output through improved handling of machine mechanics and dynamics. The BX50i has a table size of 59.1" x 37.8" and a table load capacity of 5,512 lbs. Its axes run as fast as 1,535 ipm. It features direct drive ballscrews. Its motorized, 47-horsepower spindle can rotate as fast as 18,000 rpm, and its spindle taper is HSK 63A. Spindle torque ranges to 88 ft-lbs at 2,800 rpm. It has 30 automatic tool changing stations and weighs 28,600 lbs. Hurco Companies Inc., South Level 3, Booth 338319 Cutting Tools Resist Heat, Hold Size Useful for moldmaking applications, Crystallume's Demon line of cutting tools is designed for extended cuts in difficult materials. Long tool life reduces the need to switch tools midway through the application. According to the company, the tools generate very little heat, hold size well, cut parts within tolerance and reduce the need for polishing. They also feature a coating designed to improve high-temperature stability for machining hardened steels. Crystallume, West, Level 3 Booth 432079 September 10-15, 2018 / Chicago, IL
