Vertical Lathe Precisely Machines Large, Heavy Parts
Okuma’s V920EX single-saddle vertical lathe features a powerful turning spindle and a larger work envelope, making it ideal for cutting a variety of large, heavy parts.
Okuma’s V920EX single-saddle vertical lathe features a powerful turning spindle and a larger work envelope, making it ideal for cutting a variety of large, heavy parts. The machine’s work envelope provides a maximum turning diameter of 36.22" plus 33.86" of swing over the saddle, enabling it to accommodate large, odd-shaped workpieces. Highly rigid construction and powerful ballscrews generate slideway movement to both axes for precise machining. The lathe has a maximum swing of 39.37", and an rpm range of 20 to 1,250.
The V12 turret is said to enable maximum machining productivity when paired with effective chip discharge. Optional side or rear chip conveyors can be placed to match discharge direction based on shopfloor requirements. Maintenance tasks are simplified with easy access to the air filter, hydraulic unit and coolant tank on the back of the machine.
Okuma’s Thermo-Friendly Concept is standard and automatically compensates ambient temperature changes to maintain tight tolerances. Cycle times, lead times and energy costs are significantly improved with Okuma’s open architecture OSP-P300L control and Eco suite feature.
Finding a way to fixture contoured marine propellors proved to be this shop’s biggest challenge in developing an effective automated machining cell.
The right choices in tooling and technique can optimize the thread turning process.
As demonstrated at this Cincinnati-area shop, machines that both mill and turn shine brightest when workpieces are massive.
