CHIWON MC-H Series Horizontal Machining Centers

CHIWON MC-H Series Horizontal Machining Centers Product Overview CHIWON MC-H Series high-precision horizontal machining centers integrate dual-column frame construction, T-shaped wide-span beds, and modular spindle systems. Designed for 5-axis machining of automotive engine blocks, aerospace components, and heavy-duty molds, these machines deliver micron-level accuracy under sustained high-torque cutting conditions. Standard BT40/BT50 spindles and 24-tool chain magazines ensure efficient batch production. Competitive Advantages Hybrid Guide System X/Z-Axis: High-speed roller linear guides (35W-55W) Y-Axis: Hardened box ways (MC-HS-1075/1290) or Rectangular guideways (MC-HS-1814) for vibration damping during heavy roughing. Result: 40% higher rigidity than all-linear-guide competitors. Thermal Stability Control Ball screws with internal cooling channels (±0.5°C accuracy). Spindle chiller option maintains ±1°C for precision finishing. Dual-Column Frame Structure Diagonal rib network (FEA-optimized) increases natural frequency to ≥75 Hz (industry avg: 60 Hz). Torsional stiffness ≥180 N·m/arcmin. Modular Spindle Options Drive Type Speed Torque Application Belt Drive 8,000 rpm 47-236 N·m General machining ZF Gearbox 6,000 rpm 300% higher low-speed torque Hardened steel roughing Direct-Drive 12,000 rpm Precision finishing Aerospace alloys Efficiency Features 2.8-sec tool-to-tool change time. Optional 40+1 tool chain magazine.Hydraulic pallet changer (18-sec exchange). Complete
