At IMTS 2022 OKUMA AMERICA CORP. introduced a new vertical lathe machine – the VT1000EX – describing it as the machine tool with the highest machining capability in its class, and capable of providing “new levels of productivity due to its highly rigid mechanical configuration, extreme thrust, and torque.”
The machine builder recommends the large vertical lathe for machining operations seeking to reduce cycle time dramatically for difficult-to-cut materials.
Highly rigid machine construction. The VT1000EX weighs 41,800 pounds and features a highly rigid construction and structural reinforcement, which makes it possible to execute stable operations for long operating periods. This vertical lathe includes wide guideway spacing, rigid and precise ball screws for both the X and Z axes, and a heavily cross-ribbed casting, which provides ultimate stability during ultra-heavy cutting of large workpieces.High-output, high-torque spindle. The VT1000EX spindle is “extraordinarily powerful” with a 55-kW maximum power, maximum torque of 5,310 Nm, and thrust of 30 kN on the X and Z axes. “This power and torque make heavy-duty cutting for difficult-to-cut materials possible and can even reduce cycle time by up to 51%,” according to the machine builder.
Cutting capability. The VT1000EX is reliable for machining difficult-to-cut materials, even those with high strength and superior heat and corrosion-resistance properties, such as titanium, Inconel®, and stainless steel.
The VT1000EX is delivered with a 36-tool magazine for continuous, long-run operation. Tool life is extended by a high-pressure coolant system, and chips are quickly removed with an enlarged chip evacuation system.
As noted by Okuma, the VT1000EX was designed to minimize CO2 emissions by reducing power consumption through decreased machining cycle times, shorter Automatic Tool Change (ATC) exchange times, and the inclusion of an energy-saving control system.
