Conventional lathe Dx H/W series

verticalsingle-column12 tools

Overview

• Machine structure: single-column vertical turning lathe series D, models C578Dx H/W, C5112Dx H/W, C5116Dx H/W, C5120Dx H/W
• Machine material: HT250–HT300 gray cast iron, aged and stress-relieved for high rigidity and minimal deformation
• Spindle & ram material: QT600 ductile (nodular) cast iron
• Material hardness and process: material hardness ≥ HB180; rough machining → secondary aging → finish machining
• Surface precision: manual hand-scraping of contact surfaces; crossbeam convexity correction; PTFE soft strips on tool-post slideways to reduce friction
• Gearing: forged, quenched and ground gears (40Cr / 45 steel) with ground spacers/shims for accurate assembly
• Ball screw: domestic brand (NJGR / Hanjiang), diameter φ63 mm
