In the defense world, there’s no room for failure. Every component—from aerospace housings to turret rings—is part of a larger mission. And behind those parts? Machines that can hold tight tolerances, operate under extreme stress, and run day in and day out without compromise.
At Lagun Engineering, we’ve been supplying rugged, American-built machines to defense contractors and military suppliers for decades. From legacy knee mills still running strong in base machine shops to massive bed mills producing high-precision parts for aerospace, our machines help power the industry that protects us.
In our latest video, we take a closer look at how Lagun supports defense manufacturing and which machines are doing the heavy lifting.

American Turnmaster Lathes – Strength You Can Count On
Our American Turnmaster line of manual engine lathes has earned its reputation in the defense sector by doing one thing extremely well: cutting reliably under pressure. Built right here in the U.S., these lathes are known for their rigid construction, powerful spindle motors, and tight tolerances. Whether it’s machining gun barrels, aerospace shafts, or support equipment parts, the American Turnmaster is a proven workhorse for mission-critical jobs.
Why Defense Contractors Trust It:
USA-built quality
Heavy-duty castings for vibration dampening
Ideal for medium to large components
Simple, serviceable, and built to last decades
Still a staple in defense and aerospace maintenance shops, the Lagun FTV-2F vertical knee mill has stood the test of time. Easy to run, simple to maintain, and tough as nails—this machine is often used for fixturing, prototyping, and general job shop tasks. While the industry has gone digital, the reliability of manual mills like the FTV means they’re not going anywhere anytime soon.
Specs That Matter:
High-quality Meehanite cast iron
Hardened and ground ways
Powerful variable-speed head
Precision downfeed and knee adjustment
The BM Series is Lagun’s flagship line of bed mills—perfect for defense applications requiring large part machining with pinpoint accuracy. These machines feature wide bases for stability, large working envelopes, and optional accessories like rotary tables or custom fixtures. They’re a go-to for everything from aircraft tooling to armored vehicle components.
Key Features:
Oversized Meehanite castings for strength
Wide-column designs for reduced deflection
Powerful spindle options (gearhead or direct-drive)
Optional CNC control integration (Fagor, Heidenhain, Siemens)
