Fuji Machine’s new large VTP-1000 vertical lathe is suitable for use within the gear, construction, wind power energy, aerospace and shipbuilding equipment industries.

Featuring gearless spindle technology and an RS-Slide structure, the VTP-1000, which performs precise hard turning, realises contour- and profile-cutting accuracies within +/-1um on up to 40in (1m) OD gears and bearing components.

With the VTP-1000, precise roundness on high-hardness materials (HR60 plus) is possible.

A variety of features further contribute to the VTP-1000’s high-accuracy operation, according to the company.

Twin Capto C6 receivers, for instance, ensure optimum tool tip rigidity, while a magnetic chuck eliminates the distortion associated with conventional workholding methods.

For thermal stability, this lathe has an optional coolant chiller and its heat sources are insulated with containment covers – all of which are located externally.

The VTP-1000’s heightened finishing accuracies result in up to 75 per cent shorter manufacturing times.

Each tool holder contains microchips to prevent offset errors and to verify that it is in the correct pocket.

The table diameter of the VTP-1000 is 1,000mm, the maximum swing is 1,200mm and the table load is 4,000kg.

Although it features a small footprint, this new lathe is rigidly constructed.

The column and the bed (75 per cent of the total machine weight) are made of heavy cast iron.

These components are not affected by thermal growth.

The VTP-1000 is designed for integration into an automated work cell.
