How can You Ji - Vertical turning centers help your operation?

• Gain high productivity and super precision in one machine
• Reduce floor space use versus similar horizontals
• Rock-solid machine construction for super-fine finishes
• Further rigidity from pretensioned and preloaded ballscrews in X & Z
• Spindle ensures extreme concentricity and accuracy
• Standard chip conveyor provides efficient chip removal
• Easy programming with Fanuc / Siemens control
• ALL VERTICAL TURNING LATHES ARE EQUIPPED FOR HARD TURNING!

The outstanding rigidity of the structure and design provides mechanical features for super heavy cutting, which achieves maximum machining accuracy and stability thus increasing the life of cutting tools.

Fanuc / Siemens spindle motor, high torque and high horse power spindle motor, incorporating a German ZF dual speed gearbox provide high torque and high turning speed allowing the machine to develop and extend its cutting ability to cover all applications of turning operations.

The vertical lathe combines the latest German hydrostatic and oil film bearing technology with the full hydrostatic features on the table. Both the axial carrying capacity and radial precision achieve optimal stability. It is particularly suitable for processing ultra large and ultra heavy work pieces, with a maximum weight capacity of up to 350 tons (VTH8000).

The VTS series of vertical turning lathes is designed with a fixed type cross-rail, incorporating both Automatic Attachment Changer (AAC) + ATC tool magazine to reduce non-cutting time. The design has high production efficiency, provides the best solution to complex machining functions and meets a wide range of applications.

- Two rows of rollers in the space of one.
- Saves space and lower the machine base height for easy operation.
- Low centre of gravity in the machine and low centrifugal forces.
- Nylon separators feature low inertia, ensuring the machine operation under low running torque.
- Heat dispersion and wear-resistant for longer bearing life.

- Eliminates noise and heat transmission to spindle assembly.
- Eliminates vibration transmitted to the spindle.
- Separate lubrification systems for spindle and gearbox eliminate heat transmission.
-High transmitted efficiency ( over 95%)
- Gear shift is controlled by integrated shift system

The super large cross section ram is manufactured from the highest grade steel, the ram is fully heat treated and stress relieved. The one piece ram structure is assembled inside the rigid Z axis body. This superbly rigid assembly will to raise the cutting ability and ensure the turning and machining accuracies inside deep inner diameters.

The box section design is fitted to the machine base. The heavily walled and multi ribbed design allows low heat transfer to retained good thermal stability. This design allows static and dynamic torsion ensuring high rigidity and stability of the machine base.
