What Sets MACH3 Apart
Part Size & Capacity
We can machine parts up to 84″ in diameter and 37′ in length on our horizontal lathes, and up to a 110″ swing on our vertical turret lathe. This gives us the ability to handle some of the largest and longest components required in heavy industry.Tight Tolerances
Our skilled machinists and advanced equipment maintain tight tolerances even on massive workpieces, ensuring your parts meet demanding specifications for fit and function.Material Versatility
We work with a wide variety of materials, including carbon and alloy steels, stainless steel, aluminum, cast iron, and specialty metals. Our approach is always tailored to your specific application.Project Complexity
Manual lathe turning is ideal for one-off, prototype, or low-volume production—especially for parts too large or complex for standard CNC equipment.Examples from Our Oversized Parts Portfolio
Our team has extensive experience with large part projects, demonstrating our mastery of this challenging aspect of machining. Examples of our work include:
- Industrial shafts: Main drive shafts, turbine shafts, and rolls for steel mills or paper plants.
- Heavy flanges and couplings: Used in power generation, oil & gas, and processing industries.
- Large bushings, sleeves, and housings: For mining, marine, and heavy equipment applications.
- Pressure vessel components: End caps, rings, and nozzles for tanks and reactors.
- Custom drums and rotors: For material handling or rotating machinery.
- Specialty boring projects: Deep ID boring for thick-walled cylinders or custom pipe sections.
Why Choose MACH3 for Large Manual Lathe Work?
Customers trust us for large-part machining—especially for jobs that require manual lathe work, such as prototype fabrication and other one-off or low-volume runs. Our shop can handle parts up to 50 tons, making us the go-to partner for industries dealing with oversized components.
Our services go beyond turning: we also offer welding, assembly, and fabrication. This comprehensive approach helps streamline your supply chain and reduce project lead times. You can see examples of our successful projects in our work library, which showcases our proven track record across industries.
What to Expect
