FAQ

Can this used Mazak INTEGREX 300-III ST handle turning and milling on the same machine?

Yes. This CNC mill-turn center combines turning spindles with a B-axis milling head, allowing operators to perform turning, drilling, and milling operations on a single machine. Depending on the workpiece and tooling, this can help reduce separate setups.

Does this used Mazak CNC machine have both main and second spindles?

Yes. The machine is configured with main and second turning spindles. This arrangement supports machining on both ends of suitable workpieces and can reduce manual handling between operations.

Is an automatic loading system included with this used Mazak machine?

An overhead gantry loading system is fitted to the machine. Its complete configuration, operational status, and included accessories should be confirmed before purchase.
