Since 1981, RiAlto has operated as a family-owned CNC manufacturing company from our 71,000-square-foot facility in Marion, Ohio. As one of the established CNC manufacturing companies serving Central Ohio, we combine multi-axis milling, precision turning, and in-house engineering support under one roof, so your custom CNC milling project never gets stuck waiting on an outside vendor.
Why Manufacturers Choose RiAlto for Prototype Development
Every part that comes through our CNC shop gets the same standard of work, whether it’s a one-off prototype or a recurring production run.
- 40+ years of manufacturing experience: We’ve been a trusted Ohio CNC machining service since 1981, long enough to have solved most material and tolerance challenges a new project can raise. Read the full story of how RiAlto got its start back in 1981.
- ISO 9001-certified quality system: Every order runs through the step-by-step inspection process every part goes through before it ships, checked against your print before it leaves the shop.
- Multi-axis machining capability: Our Haas and Mazak equipment includes a true CNC vertical machining center with 5-axis and pallet-changer capability, so complex geometry gets machined in fewer setups.
- Both large and small CNC machine capacity: From large-format mills with 84″ x 32″ x 30″ travel to more compact machines suited to tight-tolerance small parts, we scale equipment to the part instead of forcing every job onto the same machine.
- A partner sized for small businesses and large OEMs alike: We work with startups sending their prototype and purchasing teams placing recurring production orders, without one type of customer getting deprioritised behind the other.
- In-house engineering and CAM programming: SolidWorks, AutoCAD, and GibbsCAM support mean design questions get answered by someone who understands your part, not a call center.

Whether a drawing calls for a small CNC machine for metal parts with tight positional tolerances or a large CNC machine for oversized weldment components, our equipment mix means we’re not turning away work because it doesn’t fit a single machine’s envelope. If you’re weighing mill versus lathe versus something more specialised, our breakdown of the different types of CNC machines and what each one does best can help you talk through the options with our team.
Materials: Metal CNC Machining and Plastic Machining Services
A metal CNC machine shop is only as good as the materials it can reliably hold to spec. We machine:
Metals:
Aluminium (6061, 7075, 5052), mild steel, carbon steel, stainless steel (303, 304, 316), copper, brass, and other alloys on request. Whether you need an aluminum CNC machine shop for lightweight components or a CNC steel cutting machine for structural parts, our operators match tooling and speeds to the alloy, not a generic setting.
Plastics:
Our plastic machining services cover ABS, polycarbonate, nylon (including glass-filled), Delrin/acetal, and PEEK for high-heat or high-load applications, the same materials outlined in the full list of engineering-grade plastics we keep in stock for prototype work. Plastic machining requires different feeds, speeds, and fixturing than metal to avoid melting or chipping, and our team programs for that difference rather than treating plastic like a lighter version of metal.
Finishing options include bead blasting, anodizing (Type II and III), powder coating, painting, passivation, and deburring, applied based on how the finished part will actually be used.

Best CNC Machine Partner for Small Businesses and Growing Manufacturers
Not every company needs high-volume production capacity on day one. If you’re a smaller operation or startup evaluating the best CNC machine for small business needs, the real question usually isn’t which machine to buy, it’s which manufacturing partner can produce accurate parts at low volume without pricing you out. RiAlto quotes real jobs off real shop capacity, so a 10-piece order gets the same attention to tolerance as a 10,000-piece production run. For a sense of what drives cost either way, see our detailed breakdown of what actually drives CNC machining pricing.

Frequently Asked Questions
What's the difference between CNC milling and CNC turning?
CNC milling uses a rotating cutting tool to remove material from a stationary workpiece, ideal for flat faces, pockets, and complex geometry. CNC turning rotates the workpiece against a stationary cutting tool, which is better suited to round, symmetrical parts like shafts and bushings. Most complex parts use a combination of both.
Can you handle both small precision parts and large components?
Yes, Our equipment mix ranges from compact-footprint mills suited to small, tight-tolerance metal parts up to large-format machines with 84″ x 32″ x 30″ travel for oversized components.
Do you machine plastic as well as metal?
Yes, our plastic machining services cover ABS, polycarbonate, nylon, Delrin/acetal, and PEEK, in addition to aluminum, steel, stainless steel, copper, and brass.
What areas of Ohio do you serve?
We’re based in Marion, Ohio, and regularly serve manufacturers throughout Marion County, Delaware, Marysville, Bucyrus, Mount Gilead, Upper Sandusky, and the greater Columbus corridor, along with customers across Ohio and the U.S.
What file formats do you need for a quote?
We typically work with STEP, IGES, DXF, DWG, or native CAD files. If you don’t have a finished file yet, send a sketch or description and we’ll help you get there.
