CNC Machining for Michigan Companies

What does “near me” get you from a Michigan-based supplier?

You get a Michigan-based business, and the person who reads your print works Michigan hours. Files come in by upload or email, and the parts ship to you. The next section compares that route with a local shop and an online platform.

Where do Michigan companies get CNC parts made?

Three routes, compared below. How to get a part machined without a shop walks through each one and what to send on it, and the CNC machining parts supplier page covers the third in detail.

On the third route, one quote can hold a mixed job. A milled housing and the turned or Swiss-turned shafts that run in it are priced together. Fixtures built to your print can come with the parts they hold. A laser-cut plate and the custom fasteners that mount it go on the same order.

How short can lead times be on CNC parts for a Michigan company?

There are three tiers, shortest first. Rush: 1-2 weeks. Standard: 4-6 weeks (typical). Extended: 6-8 weeks, for jobs that aren't time-sensitive. Lead time starts at order approval. Put your need date in the part description and the quote answers it. The quote form asks which tier you want, with Standard preselected, so for a short lead time pick Rush. Rush 1-2 weeks applies to machined parts with no secondary operations. Heat treat, grinding, EDM and finishing add time, and the quote gives the real date. Rush CNC parts covers what a job needs to ship on Rush.

Are you a CNC fitting supplier for Michigan companies?

Yes. Custom fittings are quoted to your print: AN and JIC flare adapters, ORB and NPT ports, hose barbs sized to a hose ID, bulkhead fittings with their nut, cam-lock couplers, and thread-to-thread adapters no distributor lists, in 6061 aluminum, 303/304 stainless, brass or titanium. The flange or manifold block a fitting threads into can go on the same quote, and so can the bracket that holds the line.

Name the thread and the seal on each end, because the common ends seal in different ways. AN and JIC ends seal on a 37-degree flare, and JIC is dimensionally identical to AN but made to less exacting tolerances, so the print should say which one it means (source 1). An ORB port seals with an O-ring compressed into a chamfer in the port, and its threads hold the fitting but do not seal the connection (source 2). An NPT thread tapers 1 inch of diameter in 16 inches of length and seals as the flanks compress when it is torqued, with thread sealant; NPTF (Dryseal) is cut to seal without it, so name NPT or NPTF on the print (source 3). Custom machined fittings covers the styles and the rest of the callouts.

Can powder coating or anodizing go on the same order?

Yes. The finish is specified on the print and quoted with the part, and the parts come back finished and inspected. The notes below cover what each of these three callouts needs on the print; the surface finishes guide covers the rest.

Powder coat goes on as a dry powder, usually applied electrostatically, and is cured under heat. It can build a thicker coat than liquid paint without running or sagging (source 4), so mark the threads, bores and faces that must stay bare.

In typical commercial anodizing, the oxide on aluminum grows into and out of the surface in equal amounts, so each surface grows by half the coating thickness (source 5). MIL-A-8625 sets Type II, from sulfuric acid, at 0.00007 to 0.001 in, and it takes dye; Type III, hardcoat, is thicker than 0.001 in, and the added thickness raises wear and corrosion resistance (source 5). Give the type, the color, and whether the dimensions on the print are before or after anodize.

Passivation is for stainless. It removes iron contamination from the surface and restores the passive oxide layer that keeps the part from rusting (source 6).
