- Safety System (Standard Equipment)
-
- Coolant oil cut-off detecton
- Stops the machine automatically when the pressure of coolant oil decreases below specified level.
- Door safety interlock switch
- Causes the main power breaker to trip and the power to shut down when electric cabinet cover is opened.
- Lightning surge protection function
- Protects electronic circuit from high voltage to shutdown noise such as lightning.
- Auto power interception
- Switches off the power breaker on the machine automatically when the machine is stopped during the automatic operation for any reason.
- Main spindle load detection mode
- Stops the machine detecting defects in the main spindle when standard load and actual main spindle load are different.
- Cut-off tool breakage detector
- Stops the machine automatically detecting materials that cannot be completely cut-off due to the breakage failure of the parting tool.
- Tap breakage detector(Option)
- Stops the machine automatically detecting broken tap while processing the edge face of the tap.
