LK HIT-630 HORIZONTAL MACHINING CENTER

Technical Description

The 2012 LK HIT-630 Horizontal Machining Center is a robust and high-performance CNC machine designed for precision milling and machining operations. It features a powerful 35 HP main spindle motor capable of handling heavy cutting tasks with a CAT 50 spindle taper for high rigidity and tool compatibility. The machine is equipped with a dual-pallet automatic pallet changer (APC) of front spin type, allowing efficient workpiece loading and unloading, thereby minimizing downtime. Its table dimension supports high payloads, with a 630 mm by 630 mm pallet size and an indexing accuracy of 0.0001 degrees, enabling precise multi-axis positioning and complex part machining. Rapid traverse rates reach up to 1,890 inches per minute, significantly reducing non-cutting time and improving overall productivity. The machine houses a 60-tool automatic tool changer (ATC) magazine, facilitating long unattended runs and quick tool swaps for varied machining requirements. A notable feature is the 1,000 psi coolant-through-spindle system which provides effective cooling directly at the cutting zone, enhancing tool life and surface finish while reducing thermal distortion. The machine’s travel specifications approximate 41.3" (X-axis), 34.5" (Y-axis), and 31.4" (Z-axis), supporting versatile machining envelope requirements. Structural design utilizes heavy ribbed cast iron construction for rigidity and vibration damping, ensuring high precision and surface quality. Full enclosure and chip management systems further enhance operational safety and cleanliness. The LK HIT-630’s combination of robust spindle power, precise table indexing, rapid feedrates, and advanced cooling make it ideal for demanding production environments requiring accuracy and efficiency.
