Inventory no. 2220113, Machine with :

Basic machine in artificially aged cast iron with reinforcing ribs.

Carriage with preloaded roller guides; ball screw with 20 mm pitch, driven by AC motors.

The electric main spindle (C-1) and the counter spindle (A) have a highly dynamic design and are technically identical.

The swivel axis (B) of the milling spindle is equipped with a direct drive.

Water-cooled high-precision electric milling spindle, hybrid bearing, oil-air lubrication, swivelling as B-axis.
HSK 40, type E or A, 30'000 min-1, internal cooling up to 80 bar possible in turning operation or when using pushing tools, the hybrid bearings are decoupled and cannot be damaged.

CNC control Fanuc series 31i

Fully enclosed working area with guaranteed tightness, completely separated from the technical side by means of metal lamellas.
Optimised chip flow, for optimum recovery of precious metals, simplified cleaning.

Coolant system with 160 L tank capacity ; pump with 40L/min. and 3 bar delivery capacity ; feed via ring nozzle at the spindle nose with 6 outlets.

3-channel recooling unit 4kW for cooling lubricant, spindles and the direct and linear drives.

Electrical control cabinet cooling

Automatic central lubrication ; monitored by CNC control (Attention : only lubricating oils approved by Bumotec are permitted)

Diagnostic system for error and alarm messages to simplify troubleshooting.

3-colour signal lamp for status indication.
