Large lathes are engineered to tackle the most demanding machining tasks, making them indispensable for industries that require the handling of oversized and heavy duty jobs.
Big bore lathes, in particular, are designed with the power and precision needed to machine large workpieces such as big steel rollers, large diameter flanges and long shafts—components commonly found in the oil field industry and other heavy manufacturing sectors.
Thanks to their impressive large swing capabilities, these machines can accommodate a wide range of large parts, with models offering capacities from 55″ x 80″ up to 100″ x 480″.
The spindle bore diameter, which can reach up to 21 inches, is a key feature that allows these lathes to work with substantial pieces, ensuring versatility across different applications.
The robust, one-piece bed and base construction of these lathes delivers exceptional rigidity, which is essential for maintaining accuracy and stability during heavy-duty cutting operations.

Other Big Lathe Options
For customers seeking even greater flexibility, double chuck lathes are available, providing enhanced support for machining large and complex workpieces.
With their unmatched size, strength and precision, large lathes are the ideal solution for companies looking to machine heavy-duty jobs with confidence and efficiency.
Machine Tool Capabilities
Big bore lathes stand out in the machine tool market for their advanced capabilities and thoughtful engineering.
These machines are equipped with features that ensure both precision and durability, such as a 3rd rail support system that enhances cutting force and maintains accuracy, even during the most demanding operations.
The cross slide and tool holder are meticulously designed to work in harmony, allowing for smooth, precise movement and efficient machining of large workpieces. A locating pin-locking style 4-way tool post provides easy swiveling and steadfast rigidity, giving operators the flexibility to handle a variety of heavy duty turning tasks.
Standard auto lubricating systems for the slide ways help extend the life of the machine and preserve its precision over time.
For added versatility, some big bore lathes offer double chucks on both sides of the headstock, making it easier to manage and secure large or awkwardly shaped workpieces.
Rotary quill options on the tailstock further improve clamping and support for oversized parts.
With a comprehensive range of options and features, these lathes are built to handle turning applications, ensuring reliable performance and exceptional results for every machining project.
Heavy Duty Turning and Support
When it comes to heavy duty turning, big bore lathes are engineered to provide the strength, stability and support required for the most challenging applications.
Their large swing over bed allows for the machining of oversized components such as big steel rollers, large diameter flanges and extended shafts, making them a top choice for industries like oil and gas, energy and heavy equipment manufacturing.
The one-piece bed and base design, combined with features like 3rd rail support and an auto lubricating system, ensures that these machines maintain their rigidity and precision even under the stress of continuous heavy duty cutting.
Max Machine Tool Support
Both the tailstock and headstock are robustly constructed to deliver maximum support and stability, minimizing vibration and ensuring clean, accurate cuts.
The substantial weight and size of these lathes are not just for show—they are purpose-built to handle the rigors of machining large, heavy parts day in and day out. With LeBlond’s diverse product line, a variety of size and option configurations, and a reputation for reliability, companies can trust that their big turning needs will be met with confidence.
Whether you are machining for the oil field industry or any sector that requires large, precise components, big bore lathes offer the performance and support necessary to get the job done right.

Hey, guys, Chris Smith here with LeBlond. Well, to let you know, there’s some big things happening with LeBlond, and that is if you haven’t checked out our website lately, we’re offering now large lathes with large spindle bores. As you can see behind me, this isn’t the largest we can go. This is a 36 by 240. It has the six-inch spindle bore.
We can do six-inch, nine-inch, 10-inch, and 12-inch spindle bores. The swings we can go up to is all the way up to 70 inches of swing, and up to 400 inches of center distance as well. So if that is something you’ve been looking for, come check out our website, see what we can offer, and let us know what you want. The great thing about this machine, you have full control at the headstock, right here, and it is a low RPM machine at only 400 max RPM, all the way down to 4 RPM. Each one also comes equipped with a face plate, that it also has four jaws, that can also work a little bit like a four-jaw chuck with your working.
And also, when you come to the apron, you also have full range of controls of the apron. For the bed being so long, instead of walking back and forth, you’ve got full range of control at your apron as well, with emergency stop, electric brake. The other nice feature with this thing being so long, having your hangers for your rods. The machine, if you see the hook back there, will actually pick up the supports and move them up and down the bed with the carriage itself, so you don’t have to do that anymore, and it’ll also drop them off in certain positions and pick it up. But if you’re not looking for something big, and you want something with a discounted price, we’re getting ready to offer our end-of-year sale with up to 15% off on our in-stock machines, and I do have a warehouse full of machines right now, ready to go, some free tariffs, some with tariff charges, unfortunately, but we will still get you the best price we can.
So check us out. I’ll tell you the largest that we do stock is a 29 x 160, and I do have one of those in stock all the way down to our RKL-1332 gearhead. So if that’s something you’re after, and you want to take advantage of it, come check us out.
