The HWACHEON HI-TECH 550 is a dual-spindle horizontal machining center engineered for precision turning and milling operations. It features two main spindles, each rated at 2,200 RPM with 40 HP output, accommodating workpieces up to 23.220" in diameter and 43.300" in length, with a maximum chuck diameter of 15.000" and bar capacity of 4.600". The machine delivers a maximum spindle swing of 31.460", enabling comprehensive access to complex geometries. The primary tool carrier employs a turret configuration supporting 12 turning tools and 12 rotary tools, with a dedicated 10 HP rotary spindle operating at 4,000 RPM for simultaneous milling operations. With one concurrent cutting tool capability across its two-axis system, the machine provides rapid traverse rates of 787 ipm across X, Y, and Z axes. The X-axis travel spans 13.600" with maximum feed rates of 787 ipm, while the Z-axis accommodates 45.300" of travel for extended part lengths. This dual-spindle architecture enables simultaneous turning and milling operations, significantly enhancing productivity for complex multi-operation components. The combination of substantial spindle power, extended workholding capacity, and coordinated tool access makes the HI-TECH 550 suitable for high-volume production of precision-machined parts requiring integrated turning and milling capabilities.
