Travelling bridge-type machining centre has an integrated vertical turning capability for completing large, complex components in 'one hit'.
Uniport 7 Travelling Bridge Machining Centre with 3.5m integrated carousel turning station completely machines five-sides of large and complex components, including turning operations, of parts up to 4000mm in diameter. The proven flexibility of this large travelling bridge gantry machine is further increased by integrating a 3500mm rotarytable at one end of the large 12000mm X-axis (X-axis can be specified between 4000 and 18000mm). The 4000mm horizontal and 1900mm vertical clearance of the travelling gantry bridge enables large components to be completely set up for five-sided machining on the standard clamping tables.

Large ring- or cylindrically-shaped components can be completely set up for vertical turning on the rotary table.

* Powerful turning capabilities - the fully integrated rotary table of 3500mm diameter is equipped with an 2500mm diameter axial roller bearing and a 2400mm diameter radial bearing set.

This bearing configuration allows the table to receive components of up to 100 tonnes in weight.

For powerful turning operations, the Carousel Turning Station is equipped with an 80kW drive unit in conjunction with an automatically shifting two-stage gearbox.

The maximum speed of rotation of the 3500mm rotary table is 120 rev/min and the maximum torque is 43000Nm to allow highest metal removal rates.

The work area around the turning station is fully enclosed with the gantry bridge at its designated X-position for turning.

Access to the work area is from the front via large access doors.

The turning tools are loaded into a Turning Tool Adapter that is attached to the spindle nose at the lower end of the ram.

This Turning Tool Adapter is equipped with a Sandvik Capto C8 interface (option HSK-100) for automatic tool change of the turning tools from a pick-up station.

The pick-up station also acts as a separation wall between the turning station and the large stationary clamping table.

For five-sided machining of large and complex components, the flexible Unisign Right angle head can be automatically attached to the vertical main spindle.

The Unisign Right Angle Head offers the same power, torque and spindle speed as the vertical main spindle (i.e 36kW / 4.000 rev/min / 1350Nm).

Located at the front of the travelling bridge are two operator platforms, one on either side of the bridge.

Both platforms are equipped with a guarding section with operator access door to the machine work area.

At the front face of the machine, near the carousel turning station, an additional guarding section is located with large access doors for loading of the turn table.
