HITACHI SEIKI UNK CNC LATHE

This industrial spindle features a robust 3-inch bore diameter with an extended 50.25-inch length, designed for versatile machining applications requiring extended reach and stability. The spindle accommodates a comprehensive range of liner sizes from 0.52 inches to 2.400 inches, providing exceptional flexibility for processing diverse workpiece geometries and materials. This extensive liner compatibility enables operators to optimize peripheral speeds for small-diameter tools while maintaining precision across various cutting operations. The spindle's dimensional configuration suggests suitability for traditional turning centers, lathes, and specialized machining equipment where extended spindle length enhances accessibility and workholding capacity. The graduated liner sizes—spanning 12 distinct options—facilitate seamless tool transitions without requiring complete spindle reconfiguration, reducing downtime and improving operational efficiency. Such spindle architecture typically incorporates precision bearings with high-speed capability, thermal management systems, and robust housing construction to withstand demanding machining loads. The design accommodates both small and large-diameter operations, from precision drilling and reaming to heavy-stock removal, making it adaptable across multiple manufacturing scenarios. Control specifications remain unspecified, allowing integration with various CNC systems and drive technologies based on customer requirements. This spindle configuration represents a universal solution for shops requiring maximum flexibility in spindle bore utilization without investing in multiple specialized units, balancing performance, precision, and operational versatility for general-purpose and specialized machining environments.
