Cooling system:
Coolant:
External coolant supply nozzles installed at the spindle nose (vertical slide).
Coolant returns via two transverse and one longitudinal conveyor into the coolant tank. The coolant is pumped from the tank as required (via M-function or switch on the control panel) through the nozzles. Mechanical sieves are provided in the coolant tank for coolant filtration.
Optional:
For internal coolant supply (ICS), a high-pressure pump with a simple filter system is available. When ICS is activated, coolant is pumped from the tank through the high-pressure pump and filter system.

Electronic handwheel
Oil skimmer in the cooling system
Blow-off and rinse guns
Chip conveyor
Automatic wireless 3D probe (Renishaw) for workpiece probing
Automatic tool breakage control (Renishaw)

The machine has only been used for a single job. As that order is no longer present, the machine is surplus to requirements.
This is a very robust machine with high spindle performance – ideal for heavy-duty machining operations.
The machine can be inspected under power at its current location.
