Capabilities

What we run

Real photos from our floor — every part below was machined in this shop.

Precision-milled 17-4 heat-treated stainless block with bored holes and pockets

CNC Milling

4-axis vertical milling on a Haas VF-4SS with an HRT210 rotary — complex pockets, bores, and multi-face work in one setup.

Haas TL-3W lathe turning a large round workpiece with coolant lines attached

CNC Turning

Big-bore lathe work on the Haas TL-3W — long shafts, large rounds, threading, and knurling that looks as good as it grips.

Two solid copper electrical connector blocks machined from 2x4x9 inch bar

Tough Materials

304 and 17-4 heat-treated stainless, solid copper bar, castings — materials that punish tooling are our normal week.

Large 304 cast stainless ring segment, welded, turned on the lathe, and finished in the mill

One-Offs & Repairs

Weld-and-turn rebuilds, crazy bore jobs, obsolete parts with no drawing — bring us the problem, not just the print.

About the shop

Family-owned. Machinist-run.

Mayday Machine LLC is a small CNC shop on Main Street in Nephi — the kind of place where the person quoting your part is the same one running it. We take pride in work most shops would rather not touch: exotic materials, rebuilds, and jobs where the drawing disappeared decades ago.

The next generation is already standing on a stool at the controls. When we put our name on a part, it's a family name.
