Overview

CNC Milling for Prototype and Production Parts

Keystone Industries provides CNC milling on a Chevalier 2443 vertical machining center with a Fanuc control, holding tolerances to ±0.001 in. We machine prototype parts, short runs, and repeat production work from your drawings or 3D models.

Our shop also runs manual lathes and mills, waterjet and plasma cutting, and a full fabrication and welding department, so CNC parts can be cut, machined, welded, and assembled in one shop.

Frequently Asked Questions

CNC Machining FAQs

What materials can you CNC machine?

We machine carbon steel, stainless steel, aluminum, brass, and engineering plastics. Contact us about other materials.

What tolerances can you hold on CNC parts?

Our Chevalier 2443 holds tolerances to ±0.001 in. on machined features.

Do you take prototype and low-volume orders?

Yes. We machine single prototypes, short runs, and repeat production orders.

What file formats do you accept?

We accept PDF drawings, DXF, DWG, STEP, IGES, and SolidWorks files. You can attach them with the Request a Quote form.

What size parts can your machining center handle?

Our Chevalier 2443 has 43 in of X travel, 24 in of Y travel, and 25 in of Z travel.

When should I choose CNC over manual machining?

CNC machining suits parts with complex geometry, many features, or multiple identical pieces. Manual machining is often faster for one-off repairs and simple parts. We recommend the best method when we quote your job.
