The SPARK C61235/16000 is a heavy-duty manual engine lathe engineered for large-scale precision machining operations. This machine features an impressive swing capacity of 92.5 inches, enabling the processing of substantial workpieces with considerable diameter. The 629.9-inch center distance accommodates extended turning lengths, making it suitable for manufacturing long shafts, spindles, and other extended components requiring precision finishing. Powered by a robust 100.6 HP motor, the lathe delivers substantial cutting force necessary for demanding industrial applications. Operating at 160 RPM, this speed range is optimized for heavy material removal and deep-cut operations on large-diameter workpieces, typical of oil field equipment, power generation components, and heavy industrial machinery. As a manual lathe, the SPARK C61235/16000 provides operators with direct control over machining parameters, allowing for adaptive responses to varying material properties and cutting conditions. The machine's construction reflects SPARK Machine Tool Co.'s reputation as a leading manufacturer of super heavy-duty lathes, incorporating rigid bed structures and precision spindle systems that ensure dimensional accuracy and surface quality throughout extended production runs. This lathe is ideally suited for job shops, heavy equipment manufacturers, and industrial facilities requiring versatile capability to handle large workpieces across diverse materials. The combination of substantial swing, extended center distance, and powerful motor positioning makes the C61235/16000 an essential tool for specialized applications demanding both size capacity and precision in metal removal operations.
