KITAMURA HX630G HORIZONTAL MACHINING CENTER

Technical Description

The KITAMURA HX630G Horizontal Machining Center is a high-capacity CNC machine designed for precise, heavy-duty machining of large components. It features an expansive work envelope with X-, Y-, and Z-axis travels of 43.3", 36.2", and 41.3" respectively, accommodating substantial part sizes. The center is equipped with a robust NST No. 50 spindle taper and a high-performance 12,000 RPM, 4-step gear-driven dual contact spindle that delivers excellent torque and surface finish capabilities. The machine includes a 62-tool automatic tool changer, enabling efficient multi-tool operations. The worktable measures 24.8" by 24.8", supporting a variety of fixture setups. Its construction incorporates solid box ways with induction hardening, twin ballscrews, and linear scale feedback on all axes, ensuring ultra-high positioning accuracy of ±0.000078" and repeatability of ±0.000039". Rapid feed rates reach 2,362 inches per minute, contributing to reduced cycle times. The CNC is controlled by Kitamura's proprietary Arumatik-Mi system with advanced surface control for smooth, high-speed processing. The machine also supports a 2-station automatic pallet changer with optional field-expandable pallet pool systems. Manufactured in Japan using hand scraping techniques, the HX630G offers exceptional rigidity and thermal stability for close-tolerance machining in demanding production environments. Its design balances speed, torque, and accuracy, making it ideal for machining large, complex parts with consistent quality and efficiency.
