Symbol Key:
W: Guide Width (e.g., 55W=55mm) R: Rails, S: Sliders Hardened Box Way: Turcite-B coated, hand-scraped Competitive Advantages
Hybrid Guidance System X/Y-Axis: Triple roller linear guides (55W) for high-speed precision (≤10 m/min)
Z-Axis: Hardened box ways with Turcite-B coating, hand-scraped to 12-16 PPI
Result: 50% higher vibration damping than all-linear-guide machines
Anti-Deformation Design Pre-cambered crossbeam compensates for 0.08mm sag under 10-ton load
Diagonal ribbed base (natural frequency ≥80 Hz)
Heavy Cutting Capability Z-axis box way withstands 25 kN cutting force
140 N·m spindle torque (MC-G-5023) for steel roughing
Thermal Control Ball screw center cooling (±0.5°C)Spindle chiller option (±1°C)
Efficiency Features Auxiliary support system for >4m screws (prevents whipping)Chip conveyor with 300 kg/hr capacity
