Hurco will showcase its completely revamped CNC machine tool line at Booth D60 in Hall 12 at EMO. Machines on display include the VMX42i three-axis mill, the VMX42SRTi five-axis mill, the VMX24HSi high speed mill, and the mill turn TMX8MYSi multitasking lathe with sub-spindle. All of these “i” series mills include UltiMotionTM, Hurco’s patented motion control system that is reported to simultaneously improves surface finish quality and reduces cycle time by up to 30 percent.
The swivel-head design of the Hurco five-axis VMX42SRTi features a flush rotary table that is embedded, which provides an additional 3.5" of clearance in the Z-axis to support taller parts. Additionally, the rotary table operates with unlimited angular movement, which reduces cycle times because the table isn’t forced to unwind multiple times during the machining cycle, as tables that are limited to ±360 degrees are forced to do.
The VMX24HSi is the first HSM mill Hurco has introduced in Europe. The VMX24HSi (X/Y/Z travels of 24/20/24") is equipped with direct drive servos and other premium components to promote speed, accuracy, and repeatability, according to the company. The integral spindle has an 18k base speed spindle and is equipped with ABEC-7 ceramic hybrid bearings to manage the thermal issues associated with HSM.
The VMX42i is designed from the ground up to withstand the high velocities and accelerations of today’s applications. It starts with a heavy, ribbed frame made of fine grain, high-grade cast iron. The double-nut, pre-tensioned ball screws are anchored at both ends for increased accuracy and rigidity. The linear rails on all Hurco machines are larger, and spaced for increased strength, the company notes.
The TMX8MYSi will represent Hurco’s line of slant-bed lathes with live tooling and sub-spindles. The Hurco turning center has a programmable synchronous sub-spindle with C-axis control and bi-directional part transfer capability in addition to other high performance specifications, such as rapids of 950 (X-axis) and 1,200 (Z-axis), peak spindle motor horsepower of 37.3, and a live tool turret with Y-axis capability.
