CNC Machining for Replacement Parts
Parts to Drop In and Get You Running
When a critical part fails, you do not have time to chase three vendors and hope the pieces line up. You need a CNC-machined replacement part that matches the original drawing, holds the right tolerances, and lands on your dock fast. Lindsay Machine Works builds those parts every day for OEMs, plants, and maintenance teams across the Midwest.
Your equipment was designed around specific dimensions, materials, and finishes. A replacement that is “close enough” eventually causes another failure. The work below shows how you can use our CNC machining services to bring legacy and worn parts back to life with the precision they were built with.
What CNC Machining for Replacement Parts Means
CNC machining for replacement parts is the process of using computer-controlled mills, lathes, and multi-axis machining centers to reproduce a component that originally came from the OEM. You bring the drawing, the broken part, or the sample. Our team brings the equipment, the engineering, and the inspection.
That work covers a few common scenarios:
- The original equipment manufacturer no longer makes the part
- You have the drawing, but the OEM lead time is too long
- The part has been modified over the years and no longer matches the stock
- A close aftermarket replacement keeps failing in service
In each case, CNC machining lets you produce a true drop-in match instead of settling for something that almost fits.
How the Replacement Part Process Works
You can start a project with a print, a CAD file, or just the worn part sitting on a workbench. From there, the process moves through five steps.
- Send what you have. Drawings, models, photos, or the part itself.
- Get a quote. You will see clear pricing, a realistic lead time, and any questions about material or finish up front.
- Machining and setup. Programs, fixtures, and tooling are built around the original spec.
- Inspection. Critical dimensions are verified in a climate-controlled inspection area before anything ships.
- Delivery and documentation. You get the part, the records, and a program on file for next time.
For repeat orders, our saved programs, fixturing, and inspection procedures help ensure consistent quality and repeatable results from one production run to the next.
CNC Capabilities Behind Every Replacement Part
A drop-in replacement is only as good as the shop floor that builds it. Our CNC capabilities cover the range of work most replacement parts call for.
- 5-axis CNC milling on vertical machining centers up to 32 by 120 inches
- 4-axis CNC milling for multi-side parts and fixtures
- 5-axis CNC turning with live tooling and a sub spindle, up to 26 inch OD by 80 inches long
- Manual machining for oversized work, including engine lathes up to 39 inch OD by 240 inches long, and a vertical turning lathe up to 57 inch OD
- Surface, ID, and OD grinding for shafts, sleeves, bushings, and rollers
- Gundrilling up to 1 inch OD by 40 inches deep for hydraulic bodies and manifolds
When a replacement part also needs cutting, forming, or welding, those processes are available in-house, so your project does not bounce between vendors.
Materials We Match to the Original Spec
The wrong material is one of the most common reasons a replacement part fails early. You can supply the metal or ask us to source it with full traceability. Either way, the documentation stays on file with the job.

Why You Can Trust the Work
You are not just buying a part. You are buying the process behind it. Lindsay Machine Works has been producing precision parts for OEMs and end users for more than 30 years. The shop runs more than 80 machines in a 35,000 square foot facility, with a climate-controlled inspection area at the heart of every job.
That scale means you get capacity when you need it. The inspection discipline means the part you receive matches the print. Every drop-in replacement passes through a final inspection against the captured spec before it leaves the building.
Service Area
Our shop is located at 4023 N. Cobbler Road in Independence, Missouri, just outside Kansas City. We support customers across the United States and ship CNC-machined replacement parts nationwide. Local pickup and shop tours are welcome.
