Choosing the wrong machine shop is expensive. Parts that miss spec become scrap. Late deliveries become production downtime. A vague quote becomes a change order. Custom machining is precision work — abrading, drilling, cutting, forming, grinding, and shaping metal to your exact print — and not every shop is equipped to do it well.
Before you send your next RFQ, run the shop through this six-point checklist: CNC capability · custom work · in-house services · machinists · track record · communication
01CNC Capability and Modern Equipment
A shop running modern CNC equipment gives you tighter tolerances, faster production, and repeatable results. Computer control removes most human error from milling and turning. It also makes short runs of custom parts economical.
Ask what machines are actually on the floor. At Midwest Machining Solutions, our CNC systems include horizontal milling machines, vertical milling machines, and turning equipment — the core of any serious custom machining service. If a shop can’t tell you its machine list, that’s a red flag.
02True Custom Work, Not Just Catalog Parts
Plenty of shops can run a standard part. Fewer can take a worn-out component with no drawing, reverse-engineer it, and deliver a replacement that fits. Custom machining demands attention to detail, special tooling, and machinists who can problem-solve — not just load a program.
Look for a shop that welcomes one-off parts, obsolete part reproduction, and reverse engineering. If your chosen shop has these skills, your project gets built to spec and on schedule.
03Full In-House Capabilities Under One Roof
Every hand-off between vendors adds lead time and risk. A shop with complete in-house equipment can quote one price, own one schedule, and control quality from raw stock to finished part.
Beyond custom machining, we handle fabrication, waterjet cutting, gearbox rebuilds, keyed shafting, and a range of other services — one PO, one shop, one point of accountability.
04Experienced Journeyman Machinists
Equipment is only half the shop. The other half is the people running it. Trained, experienced machinists work faster, catch problems at setup instead of at inspection, and know how each material behaves under the tool.
Our journeyman machinists have decades of combined experience and can work with almost any material or project. Ask any shop you vet about the tenure and training of the people who will actually cut your parts.
05A Proven Track Record and Certifications
Established shops are more reliable than start-ups. They have already solved the hard problems — complex specs, tight deadlines, difficult materials. Midwest Machining Solutions is a WBE-certified custom machining shop serving manufacturers across the greater St. Louis metro, on both the Missouri and Illinois sides of the river, in the industries that keep the Midwest running: agriculture, manufacturing, and heavy industry.
06Clear Communication and Honest Turnaround
A good shop quotes quickly, tells you the real lead time, and calls you before a problem becomes a delay. When you request a quote, note how fast and how specific the response is. It predicts how the whole job will go.

Custom Machining FAQ
What is custom machining?
Custom machining is producing parts to a customer’s unique specs rather than from a standard catalog — one-off components, replacements for obsolete parts, or short production runs built to your print or sample.
What’s the difference between custom machining and CNC machining?
CNC machining describes how a part is made (computer-controlled equipment). Custom machining describes what is made (a part built to your unique spec). Most custom machining today is done on CNC equipment for precision and repeatability.
What should I send to get a quote?
A drawing or CAD file is ideal, but not required. A sample part — even a worn one — is often enough for us to reverse-engineer it. Include material, quantity, and when you need it.
What areas do you serve?
We serve the greater St. Louis metro on both sides of the river — Missouri and Illinois — and ship custom parts throughout the Midwest.
