Point
E4000 controller ：Two load meter lighting（continuous duty area）
This CHK-type slim spindle head can get close to the work,
the tool over hang can be minimized.
The processing efficiency is improved by 2 times on the grounds that
Spindle speed and feed can be increased.
↓
The minimized tool overhang enables precise processing.
The tool life improves due to efficient chip evacuation.
