Used Okamoto Machines We Buy
Used Okamoto machines reach Machine Tool Exchange as a grinding book almost end to end: 562 of the 577 Okamoto listings in this hub file under CNC grinding machines. ACC is the largest model family at 210 listings, followed by PSG at 78 and OGM at 45. We buy this equipment outright from the companies that own it, no consignment and no broker.

What the 577 Okamoto Listings Actually Hold
This hub carries 577 Okamoto listings and one brand only. The category split is complete and it is lopsided: CNC Grinding Machines 562, CNC Miscellaneous Machines 7, CNC Horizontal Machining Centers (HMC) 3, CNC Gear Machinery 3, Metal Cutting 1, CNC Horizontal Boring Mills 1. That puts 97.4 percent of the hub in one category and leaves 15 listings, 2.6 percent, spread across the other five. The concentration is the story here, not a gap. Measured against our CNC grinding hub, Okamoto is the most common builder across our CNC grinding listings, 562 of 2,198, ahead of Chevalier at 523 and Tos at 355, rank 1 of the 32 brands in that category. Depth does not mean repetition, either. Those 577 listings carry 517 distinct model designations, so close to nine entries in ten are a different machine string from the one before. Almost nothing in this book repeats from one listing to the next.
ACC, PSG and OGM: the Families That Carry This Hub
By leading token, ACC is the largest family at 210 listings, 36.4 percent of the hub, all 210 filing under CNC Grinding Machines. PSG follows at 78 listings, then OGM at 45, LINEAR at 25, IGM at 21, PFG at 17 and ACCUGAR at 14, each filing entirely into CNC Grinding Machines. Below them, 618 at 10 and 1632N at 7, the only family in this list that does not file entirely into grinding, 6 grinding and 1 metal cutting, then 612 at 5, ACC16 at 5, ACC12 at 4, 820A at 4, 1624N at 3, 820N at 3 and OGM12 at 3. Families of two or more account for 512 of the 577, so the remaining 65 are one-offs. The strings a searcher types turn up here verbatim: ACC-1632DX, ACC-16-32DX, ACC-12-24DX, ACC-12-24ST, ACC-124DX, ACC-618DX3, ACC-820-DX, ACC-820-DXNCP, ACC-20-36-DX, PSG-84, PSG-158DXNC, PSG-308, IGM-2MB, OGM-12, ACCUGAR-124N, 1632N and GC-40. ACC16, ACC12 and ACCUGAR are separate roll-up keys, not part of the ACC 210.
What Determines the Offer on a Used Okamoto Grinder
With 562 of 577 listings here filing as grinders, the scoping call is a grinder call. Jason Puuri asks about the wheel spindle first: hours if anyone tracked them, how it sounds and pulls, and what has been done to it. Then whether the machine still holds size and finish on a test grind, because that one answer settles more than a spec sheet. After that, way and slide wear, control generation and whether parts and service for it are still reachable, chuck and wheel packs on hand, dressers, coolant and filtration, and any loader or in-process gauging that comes with it. None of it runs through a formula. Jason weighs those details himself against what the machine needs to go back to work. Only 227 of 577 listings record a build year, and those run 1977 to 2026, so a late-1970s machine and a current-year machine are different conversations.
The 15 Okamoto Listings That Are Not Grinders
Take 562 grinding listings out of 577 and 15 are left. Named, because the split is complete: CNC Miscellaneous Machines 7, CNC Horizontal Machining Centers (HMC) 3, CNC Gear Machinery 3, Metal Cutting 1, CNC Horizontal Boring Mills 1. Part of that is traceable in the family roll-up. The HMC key splits 2 into horizontal machining centers and 1 into horizontal boring mills, and the 1632N key puts 1 of its 7 into metal cutting. The catalog gives us a category for those and nothing else, so we are not going to characterize them or guess at model names. If what you have is an Okamoto that is not a grinder, it does not need to match anything on this page. Send the full designation off the plate and what it is set up to do, and it gets scoped like a grinder. Our horizontal machining center and gear machinery hubs cover those categories broadly.
Have This Ready Before You Call
The most useful thing you can send is the full designation exactly as it reads off the data plate, not a partial. Inside this hub alone, ACC-1632DX, ACC-16-32DX, ACC-16.32DX, ACC-12-24DX, ACC-124DX and ACC-12-24ST are separate catalog strings sharing tokens, and ACC-618DX3 and ACC-618-DX3 differ by a single hyphen. With 517 distinct designations across 577 listings, the exact string is what places a machine. Serial number next, then control type and generation, build year, wheel spindle hours if they were ever tracked, the chuck and wheel packs on hand, whether it still holds size and finish, and whether it is running now or has been sitting since a job ended. On the year: only 227 of the 577 listings in this hub record one, which is why we ask instead of looking it up. If the plate is painted over, the serial and a clear photo still give us something to work from.
Selling an Okamoto Outright Instead of Listing It
Machine Tool Exchange purchases the machine. No consignment, no listing fee, no broker taking a slice, and no requirement to buy something new the way a trade-in works. You are not waiting on a buyer to appear. One ACC or a whole grinding department comes out on a single quote and a single pickup schedule, which matters when a cell has to clear by a date. Machines idle since a job ended, pulled during a changeover, or parked while somebody decides about a spindle all still get scoped. What speeds the close is proof the company owns the equipment outright rather than on a lease or finance agreement. Grinders are what we chase hardest, and we buy well past this one badge: Chevalier, Tos, Blanchard, Heald Machine Co and Landis Machine Co grinders, and across the wider shop Mazak, Haas, Okuma, Doosan, DMG MORI and Makino. This hub itself is Okamoto only.
Common questions
How do I sell a used Okamoto grinder?
Send the designation off the data plate, the serial, and photos of the control screen and work zone. Jason Puuri scopes it and a number comes back.
Do you buy Okamoto ACC, PSG and OGM machines?
Yes. ACC at 210 listings, PSG at 78 and OGM at 45 are the three largest families here, together 57.7 percent of the hub.
Do you buy older Okamoto grinders, or only recent machines?
Both. The 227 listings here that record a build year run 1977 to 2026. Condition and control generation weigh heavier than the year on the plate.
Is this consignment, or do you buy the machine outright?
We buy it outright. Machine Tool Exchange is not a marketplace and not a broker, so there is no consignment, no listing fee, and no waiting.
How is a used Okamoto grinder valued?
By factors, not a formula. Wheel spindle condition and hours, whether it still holds size and finish, way and slide wear, control generation and parts availability, chuck and wheel packs.
Do you buy Okamoto machines other than grinders?
Yes. 15 of 577 listings here sit outside CNC grinding: 7 miscellaneous, 3 horizontal machining centers, 3 gear machinery, 1 metal cutting, 1 horizontal boring mill. Tell us what you have.
Will you buy a whole grinding department at once?
Yes. A book of 577 listings under one builder, 517 of them distinct designations, is what a department coming out at once looks like. One quote, one pickup.
Thinking about selling Okamoto Machines?
One builder, one category, 577 listings deep. The first question a buying shop asks about an ACC or a PSG is not what the nameplate reads, it is whether the wheel spindle is sound and whether the machine still holds size and finish. Jason Puuri weighs that himself against hours and control generation. Send the whole designation off the plate, hyphens and all, with photos of the control screen and the work zone.
