Hurco will show its high-speed VMX42HSi mill, that is equipped with direct-drive servos, an 18-k integral spindle and X/Y/Z travels of 42" × 24" × 24" to handle the rigors of high-speed machining. The automatic tool changer supports HSK tooling and has a chip-to-chip time of 4.5 sec. The air-over-oil spindle lubrication is designed to distribute oil evenly and prevent bearings from grease starvation.
The mill also is equipped with Hurco’s patented UltiMotion™motion control system, which is said to reduce cycle time as much as 30 percent while simultaneously improving surface finish quality. This system uses complex software algorithms for motion planning instead of conventional hardware, optimizing look-ahead to as many as 10,000 blocks, the company says.
The VMX42HSi is built to last and to retain accuracy, with larger linear rails that are mounted to a machined shoulder for increased rigidity. In addition, the rails are wedge-locked to the frame to reduce vibration instead of face-milled.
Optimized for the advanced tool paths generated by CAM systems, the Hurco integrated control features a 64-GB solid-state drive, 2 GB of memory, a 2-GHz dual-core Intel processor and processing speed as fast as 2,277 bps.
