Double-Column Machines Combine Speed, Stability

IMTS 2018: Hurco adds two new offerings to its BXi series of double-column machining centers for the die/mold and aerospace industries. 


The latest additions to Hurco’s BXi CNC machine series are the BX50i, with X-, Y- and Z-axis travels measuring 37.4" × 53.2" × 23.6", and the BX60i, with X-, Y- and Z-axis travels measuring 52.1" × 63" × 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 structure and isolates the bridge from part weight.  

The machines feature integrated WinMax control software and the UltiMotion motion system. The control software supports multiple programming methods, including conversational programming, NC programming, and a Hurco-specific feature 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" × 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.

Cutting Tools Resist Heat, Hold Size

With so much happening in a busy show year between NPE2018, Amerimold 2018 and IMTS 2018, MoldMaking Technology is revisiting some of the technology that was on display. In case you missed it: At IMTS 2018, Crystallume had its Demon line of cutting tools, which is designed for extended cuts in difficult materials.
