XV-3 [3, 4 inch] CNC VERTICAL LATHE

Three spindles are installed in one machine. Power tools can be mounted, allowing turning and a variety of other machining including horizontal hole machining too. The transport device that passes laterally through the machine can transfer a workpiece to each of the three spindles, allowing any required process configuration such as 1-1-1, 1-1-2, 1-2-2, and 1-2-3. Because the individual lathe units have equal capabilities, the same process can be shared among the three spindles without considering differences in capability.

A self-loading configuration is adopted to move the spindle directly to a traverse-type transfer device for workpiece transfer. The transfer device has a workpiece turnover function, eliminating the turnover device between processes. The number of transfers between chucks is reduced, which also decreases the possibility of momentary stops, the number of setup changes, and setup man-hours.

The inverted spindle is provided at the front of the machine. The major mechanical parts, such as the turret, slides, and transfer device are also placed at the front of the machine to ensure ease of maintenance and space savings. In addition, oil mist lubrication is adopted for the spindle, simultaneously achieving high spindle speeds and long service life.

Three spindles and a turret are integrated into one machining chamber. The machine handles the processes equivalent to three machines, only with one coolant tank, oil controller, chip conveyor, mist collector, etc.
Cost reductions can also be expected because there is no need for inter-process workpiece transfer equipment or turning equipment.
