New YOU JI VTH-6000ATC-III | Vertical Boring Mills (incld VTL)

Description

You Ji VTH vertical turning centers are engineered for heavy duty turning of large workpieces. The series is comprised of 32 machines with standard cutting diameters ranging from 130″ to 350″ (3300 mm to 8900 mm), and spindle power extending from 100 hp to 133 hp.

The heavy-duty spindle incorporates a high precision hydrostatic bearing designed to withstand high axial and radial loads. In the hydrostatic system, pockets of oil between the base of the machine and the table eliminate contact between mating surfaces and promote friction-free operation. A dual-wound 133 hp Fanuc high-torque spindle motor is coupled with a 2-speed ZF helical planetary gearbox. The combination of the high/low motor and 2 speed gearbox provides the benefits of a 3-speed transmission. Power is transmitted through a Class 1 ring and pinion gear that provides a further gear reduction and torque multiplication. This massive spindle can support a table load of up to 650,000 lbs. With the C-axis option, dual 100hp tandem spindle motors allow 10 arc second positioning and 5 arc seconds repeatability.
