: BOST VTL C Series | Large CNC Vertical Lathes

The BOST VTL C series is designed for manufacturers requiring a combination of heavy-duty vertical turning, high accuracy and flexible machining capability.

Its modular architecture allows BOST to configure a machine around the customer's component and manufacturing requirements. The series is available in large-diameter configurations, with published models extending from 3,600 mm to 8,500 mm turning diameter.

​

Engineered for Large-Scale Machining

The VTL C design combines robust structural components with hydrostatic guideways to support geometric precision, thermal stability and long service life.

Depending on the selected configuration, the machine can be equipped for turning, milling and drilling, with additional machining options and tooling arrangements tailored to the application.

Configuration Options

• Moving or fixed crossrail, depending on the design.

• Single or double RAM arrangements on applicable models.

• C-axis capability where specified.

• Milling heads and dedicated machining accessories.

• Flexible tool-storage and tool-changing configurations.

• Optional full enclosure and oil-mist extraction.

• Pallet-changing systems and automation options.
