Used TOS Machines We Buy
Used TOS machines come through Machine Tool Exchange as a boring, turning and grinding book, and we buy them outright from the companies that own them. This hub holds 2,134 TOS listings: 473 CNC lathes, 355 grinders, 283 horizontal boring mills and 197 milling machines. Here is what actually moves an offer.

What Is in the TOS Book Right Now
Every one of the 2,134 listings on this hub is a TOS, and the catalog files them across 24 categories. CNC lathes lead at 473, ahead of 355 grinding machines, 298 filed as CNC miscellaneous machines, and 283 horizontal boring mills. Then 197 milling machines, 144 boring mills and 94 gear machines. The tail is still real equipment: 56 vertical turret lathes, 50 gantry and portal mills, 50 vertical boring mills, 40 drilling and tapping centers, 35 vertical machining centers, 19 horizontal machining centers and 12 band saws, down to a few press brakes and rotary tables. Read the 298 honestly, because CNC miscellaneous machines is a catch-all facet rather than a machine type, which is why it sits third. Group the facets and the shape gets clearer: 531 listings sit in a turning-named category, 477 across the three boring-mill categories, 359 across the two grinding categories, and 305 across milling and machining centers.
TOS Boring Mills: WHN, WHQ, WH and W100A
477 of the 2,134 listings sit in one of the three boring-mill categories, and 283 of those are filed as CNC horizontal boring mills. WHN carries that run with 101 listings, 53 filed as horizontal boring mills and 48 as boring mills. WH follows at 42, split 24 and 18. WHQ holds 41, split 29 and 12. W100A holds 33, with 30 of those horizontal. Below that come WRD at 19, WD at 12 split evenly, WHQ 13 at 10, WHR at 9, W9A at 7, WFQ and W100 at 5 each, WH10CNC at 4 all horizontal, WHN 13 at 4, and W75, W9 and WHN 138C at 3 apiece. Look yours up by the exact plate designation, not the prefix: WHN, WHN 13 and WHN 138C are separate buckets here. Our own boring mill value page names TOS and TOS Varnsdorf among the brands buyers look for, for known accuracy, available parts and track record.
TOS Lathes and Vertical Turning: SN, SU and the SK Families
Turning is the biggest block: 473 listings are filed as CNC lathes, and with 56 vertical turret lathes and two smaller facets, 531 sit in a turning-named category. SU is the largest model family at 103, with 101 of those filed as CNC lathes, and SN is third at 88, 84 of them filed as lathes. Then SUA at 50 and SUS at 26, all lathes, SUI at 46 with 45 lathes, and SV at 17. Below those, SU 100 at 7, SN 63B at 6, and SN 40, SN 32 and TT at 5. On the vertical side, SKJ at 23 splits 13 vertical boring mills and 10 VTLs, SK at 18 splits nine and nine, SKQ at 11 leans VTL, and 18 of the 19 SKIQ listings land across vertical boring, VTL and lathe facets. SK machines are filed under both vertical boring mill and VTL, so either search finds them.
TOS Cylindrical Grinders and Gear Machines
CNC grinding machines is the second largest category at 355 listings, plus four tool and cutter grinders, and the B-series families are the most category-pure in the book. BUB at 51, BUC at 47, BUA at 28, BRH at 17, BPH at 13, BU at 12, BUAJ and BUT at 11 each, BPV at 6, UB, 2UD and BDU at 5 each, and BN, BU 28, URB, BHS and BHE at 3 each are all filed under CNC grinding machines, with only BHU breaking the pattern at 42 of 43. That is measured off the catalog, which is why a B-prefix plate is quick for us to place. Gear machinery is 94 listings. FO leads at 20, 19 of them gear machines, then OFA at 19 and OHA at 14, both filed entirely under gear machinery. A BUC 85C/4000 MULTI here carries TOS Celakovice on its brand line, typed as a universal cylindrical grinder.
What Moves the Number on a Used TOS
Here is what makes a TOS different from most brands we quote. 1,665 of the 2,134 listings carry no build year at all. Only 469 do, and among those the oldest is from 1969 and the newest from 2026. The data plate is the fastest way to place a TOS, and a missing year is normal rather than a problem. The second number that matters: 2,073 distinct model designations across 2,134 listings, so nearly every unit gets scoped on its own. Production spread also means control generation and any retrofit work weigh as much as the iron, and an early-end and a late-end machine are different conversations under the same designation. Beyond that, the determinants are the usual ones: brand, model, year, condition and control type. Photos speed the evaluation but are not required. Jason Puuri weighs these himself rather than running a formula, and an offer typically comes back within 24 to 48 hours.
Selling a TOS Outright, and Clearing the Rest of the Floor
MTE buys outright. We are not a broker, an auction platform or a consignment and listing service, so you are selling to us rather than waiting on us to find a third party. No listing fees, no broker fees. Rigging, crating and freight are on us in all 50 states, and you are paid at pickup rather than net 30. Running, idle or already decommissioned all get quoted, one machine or a full facility. TOS is already named on our boring mill sell page under the brands we commonly buy, so a WHN or a W100A is no exception case. Machine Tool Exchange is an affiliate of Superior Machine and Tool, buying and selling industrial machinery since 2012. Mixed floors work the same way: we buy Fanuc, Mazak, Haas, Okuma, Doosan, DMG MORI, Amada, Toshiba and Makino equipment too, and it goes on the same quote and pickup schedule as your TOS machines.
Common questions
Who buys used TOS machines?
Machine Tool Exchange buys TOS equipment nationwide, directly from the owners. We are not a broker, and TOS is named on our boring mill sell page under the brands we buy.
Do you buy TOS WHN and W100A horizontal boring mills?
Yes, and WHN is the deepest boring-mill run in this book. 101 WHN and 33 W100A listings sit here, and 283 of the 2,134 are horizontal boring mills.
Do you buy TOS SN and SU lathes?
Yes. SU is the largest family in this book at 103 and SN is the next largest lathe family at 88, with 473 of the 2,134 listings filed as CNC lathes.
Do you buy TOS BUB and BUC cylindrical grinders?
Yes. 51 BUB and 47 BUC listings sit in this book, and every one is filed under CNC grinding machines, out of 355 TOS grinders in total.
My TOS has no year on the data plate. Will you still buy it?
Yes. Most TOS listings here carry no build year, 1,665 of the 2,134, so a missing year is normal. The plate model and serial are enough to place it.
How much is a used TOS machine worth?
It depends on model, build year if the plate carries one, condition, control type and tooling. Send those details and we send a market-based offer, typically in 24 to 48 hours.
Do you buy TOS gear hobbing machines?
Yes. 94 gear machines sit in this book, including 19 OFA and 14 OHA listings, and we buy gear hobbers, shapers, grinders and shaving machines in any condition.
Thinking about selling TOS Machines?
Most TOS listings here carry no build year, so the plate, not the paperwork, is where a TOS quote starts. SU lathes and WHN boring mills come through most, at 103 and 101, and they are entirely different machines, which is why we ask for the designation first.
