ณ์Development concept
1.Improved Y-axis thermal growth
2.Improved of machining surface
3.High-speed ATC 4.Machine specifications
5.New various functions
6.Accuracy data
7.Improved items
1. Improvemed Y-axis thermal growth
Thermal growth measures by Layout change of Z-axis feed system
Countermeasure for thermal growth of Y-axis direction
CEGAIIICEGA-SS
As Z-axis guide is positioned near the center of spindle, Y-axis thermal growth is suppressed.
Z-axis Z-axis LM guide Rail ⇒Saddle Carriage ⇒Spindle head - Distance between machining point and supported point is not varied, if Z-axis moves. Z-axis straightness with stability - There is no overhang on Z-axis. High accuracy positioning |

High performance spindle
1) Spindle employs Built-in motor made by FANUC for less heat generation
2) Max 30,000rpm (OP : 40,000rpm)
3) Ceramic bearings
4) THERMAL GROWTH CONTROL Temperature control ±0.1C by forced circulation of heat exchange fluid (Dual bypass PID control)
5) New Spindle internal structure secures improvement on dynamic run-out
