                      • VERTICAL LATHES

                      • Our vertical lathes have been designed to create new high standards of turning and machining capabilities for users in the most demanding industries.
                        Precision and quality in turning, hard turning, grinding, milling, drilling and measuring operations. They can also incorporate special heads/spindles for the most demanding customizations.

                          • TV - Cross slide vertical lathe

                          • The TV cross slide vertical lathe has been designed to create new high standards of turning and machining capabilities for users in the most demanding industries.

                            Machine with cross slide configuration for maximum accuracy: as the cross slides are guided over the entire stroke length a constant torque is ensured irrespective of where the cutting tool is working (thus in contrast to the ram saddle concept, constant guidance is ensured in all stroke positions).

                            TV machines guarantee outstanding performances in combining turning, hard turning, drilling, grinding and measuring operations with high precision and mass productivity.

                          • VTC - Customized lathe

                          • The DANOBAT Vertical Turning Centre are extremely rigid.

                            The main elements of the machine such as the base, the column/columns and the cross rail are ribbed castings providing a high degree of stability to the machine assembly.

                            The VTC range is optimized to achieve excellent machining results regarding dimension accuracy and surface finish performing the best results for X, Z and C axes positioning and reducing deformations due to thermal expansion.

                            The machine design and their structural cast iron components, enable a high thermal stability face to temperature changes caused by the main motor, ram motor, etc. During every machine test, we check that those thermal expansions do not affect the quality of the machining.

                            Hydrostatic technology can be applied in the following areas of the machine:

                            Hydrostatic slideways are used in both the X and Z axes.
                            The table is supported radially and axially by hydrostatic elements.
