Two Machining Centers for High Speed Machining
Hurco’s VMX24HSi and VMX42HSi machining centers are designed for speed, accuracy and repeatability, the company says.
Hurco’s VMX24HSi and VMX42HSi machining centers are designed for speed, accuracy and repeatability, the company says. The X-, Y- and Z-axis travels measure 24" × 20" × 24", respectively, on the VMX24HSi and 42" × 24" × 24", respectively, on the VMX42HSi. Both machining centers are equipped with direct-drive servos and an integral spindle with an 18,000-rpm base speed spindle and ABEC-7 ceramic hybrid bearings. Air-over-oil spindle lubrication distributes oil evenly and prevents grease starvation in the bearings. Large linear rails are mounted to a machined shoulder to increase rigidity, and wedge-locked to the frame to reduce vibration. Pre-loaded and stretched ballscrews are anchored at both ends. The automatic toolchanger supports HSK tooling and provides a chip-to-chip time of 4.5 sec.
Both machines feature Hurco’s integrated control optimized for high speed machining with a 64-GB solid-state drive, 2 GB of memory and Dynamic Variable Look-Ahead capable of as many as 10,000 blocks. The control incorporates a 2-GHz dual-core Intel processor with a processing speed ranging to 2,277 bps. The machines are also equipped with UltiMotion, Hurco’s motion control system designed to reduce machine jerk and improve surface finish quality.
