Machining

CNC & manual machining

From a single replacement shaft to repeat production parts, our manual lathes and mills in a range of sizes and our CNC lathes and mills handle work in almost any size and material.

One-offs, repairs and production runs

Our manual lathes and mills, in a range of sizes, are the right tools for oversized parts, repairs and one-of-a-kind jobs. Our CNC lathes and mills make repeat parts accurately and efficiently. Having both lets us pick the fastest way to make your part right, and our welding shop is right there when a part needs building up first.

FAQ

Common questions

What's the biggest part you can machine?

We have made shafts up to 10 inches in diameter and 10 feet long, and our largest lathe handles big, heavy work. For anything oversized, call us. Portable machining at your site may also be an option.

Do you do CNC production work?

Yes. Our CNC lathes and mills make repeat parts and multiples efficiently, and our manual lathes and mills handle one-offs, repairs and oversized work.

Can you match an existing part?

Yes. Send a sample or a print and we will duplicate it. If the original keeps failing, we can suggest improvements.

Do I need a drawing to get a part made?

No. A sample, a sketch with measurements, or even photos are a good start. We can also produce 2D and 3D prints.
