The NBT Machining story.

After spending almost two decades perfecting his precision machining and management skills as a manufacturing supervisor, Ted Rawson decided to start his own business. Ted founded NBT Machining in 1979 and set out to create a company that would provide precision-machined parts and assemblies and fast, responsive customer service at very competitive prices. Today NBT offers high quality CNC machining and precision assembly services – along with in-house certified welding, honing and lapping – in a modern, full-service manufacturing environment.

New Automatic Horizontal Band Saw

December 2018

NBT Machining has purchased a new Amada HA250W Automatic Horizontal Band Saw. This new saw features rugged construction designed to cut a variety of materials from high-temp alloys to free-machining materials with reliable precision. With a 9.0” diameter capacity and coolant and chip-disposal systems, this saw can handle the tough jobs and run unattended for extended periods of time.

Not every precision machine shop has in-house sawing capabilities, but we do. At NBT Machining we like to control the manufacturing process as much as possible and this means moving outside processes inside whenever we can. Along with materials sawing, NBT offers in-house honing, lapping, welding, and vertical band sawing. By streamlining the manufacturing process, we deliver quality, reliability, and solid value for our customers each and every day. Contact us to learn more about NBT Machining and find out what we can do for you.
