Rigid Structure Multi-tasking Systems UT-SY Built-in motor driven spindle Spindle Belt driven main spindle Thermally symmetrical design on the head stock diminshes distrotion and provides stable accuracy on work pieces even in continuous high speed machining. The spindle is supported by a double row of tapered roller bearings in the front and rear of the spindle to resist axial cutting force, while self-alignment angular contact bearings provide tremendous radial load capability. One-piece Slant Bed Structure UT-3SY Main and Sub Spindles Synchronization C1-Axis The machine bed is made of one-piece highgrade Meehanite casting to allow heavy cutting capabilities. The wide hardened and ground box ways are coated with Turcite and hand-scraped for ultra-precise fitting to reduce vibration while offering better tool life and surface finishes. Each axis structure is directly driven by precision ballscrew and powered by AC servo motor for smooth slide movement with virtually no backlash. Available on both the main spindle and subspindles, C1 and C2 axes provide positioning resolution up to.1 degree to accomplish three dimensional contouring, combined round and prismatic machining by harmonized control of the spindles with the X and Z axes. Exact synchronization between the main spindle and sub spindle at any rotation speed can be programmed to perform part transfer for secondary machining to enhance part transfer for secondary machining to enhance production efficiency and reduces idle time. C2-Axis Y-axis Y-axis with +/-4 and +/- 5 mm of stroke is available for performing thread milling, complex off-center milling and drilling operations on the main or sub-spindle by combining live tool turret. The Y-axis travel is achieved by the simultaneous movement of the two independent slides.this design distributes cutting force over the two slides assuring exceptional rigidity and maximum accuracy. 1 UT Series UT Series 2
