Used Grob Machines We Buy
Used Grob machines come to us straight from the shops that own them, no broker, no auction, no listing fee. This hub lists 214 Grob machines, and they split into two different populations: G-series universal machining centers on one side, the older 4V and NS vertical band saws on the other. Here is what moves an offer on each.

What Sets the Offer on a Used Grob
Two things carry most of the weight on a G-series universal: the control generation, and whether the machine still holds tolerance after its hours. Grob built these around Siemens Sinumerik, and an 840D sl machine reads differently than an older screen a shop can no longer get service parts for. Spindle hours, the pallet and automation package, and whether tooling comes with the machine all move the number as well. Jason Puuri weighs hours and condition himself rather than running a formula, which is part of why there is no blanket Grob number on this page: these 214 listings carry 113 distinct model numbers, so a per-brand average would tell you nothing about yours. A saw gets scoped on completely different terms. With 45 vertical machining centers sitting beside 23 CNC vertical band saws in this same hub, a G550 conversation and a 4V-18 conversation share almost nothing but the nameplate.
The G-Series Universals: G550, G350 and the Rest
On the machining-center side of this hub, G550 is the family token that appears most, at 13 listings, with G350 next at 8. As single model numbers, G550 shows 8 and G350 shows 7, with another 6 catalogued as G 550 with a space and 4 more as G550-185. Below those, G520 and G500 each show 4, and G552 shows 3. The rest of the Grob book here is thin but real: G440, G350T, G840, G326, G640, G550T, G550A, G750, G350A, G150, G300 and G750T each appear twice. Suffixes are not cosmetic, so a G550 and a G550T get scoped individually rather than lumped under one family number. Behind these model numbers sit 45 vertical machining centers, 19 five-axis machining centers and 15 horizontal machining centers. We buy the compact G350, the mid-range G520, the five-axis simultaneous G550, the large-format G750, the G500 series, the G-series HMC variants and G-series automation cells.
Grob Saws: the 4V, NS and FAB Lines
The G-series gets the attention, but the single most common machine number in this hub is not a machining center at all. The 4V-18 vertical band saw appears 24 times in this hub, more than any G-series variant reaches even after its spellings are merged, and 4V is the largest model family token in the book at 42. Behind the 4V-18 sit the 4V-24 at 9 and the 4V-36 at 5. The NS line follows: NS-18 shows 5, another 4 sit as NS18, and NS24, NS36 and NS-24 fill out the rest. The FAB line runs FAB-18 and FAB-30, and the 6V-36 turns up as well. Counted by category, 43 of the 214 listings sit under a saw label. On a saw, send the data plate model number, the blade wheel size and whether it still runs under power. These trade on their own terms, not on control generation or spindle hours.
What the 214 Grob Listings Cover
Nineteen category labels cover the 214 listings, and they add up exactly. Metal Cutting is the largest at 68, though that is a general bucket label rather than a machine type, so it says nothing about what those units actually are. Below it: 45 vertical machining centers, 23 CNC vertical band saws, 19 five-axis machining centers, 15 horizontal machining centers, 10 CNC saws, 6 CNC band saws and 6 listed as miscellaneous. The tail runs 5 horizontal boring mills, 4 lathes, 3 grinding machines, 2 vertical bandsaws, 2 turning centers, and one each of transfer machine, boring mill, gear machinery, band saw, milling machine and saw. Across all of it are 113 distinct model numbers, including oddities like the 2S36U, the BZ 600, the ZRM9 and a 352 5-Axis. The payoff for a seller: if your Grob is not a G-series universal, it still belongs in this hub, and we still buy it.
Selling Outright Instead of Trading In
Grob runs a factory trade-in and buy-back path, but it is tied to buying a new machine. If you simply want the old one off the floor, MTE buys it outright with no new-machine purchase attached. We are a direct buyer, not a broker, a listing service or an auction platform, so you are selling to us rather than waiting on us to find a third party. MTE is a division of Superior Machine and Tool and has been buying and selling used CNC equipment since 2012. We cover rigging, crating and freight at no cost to you, pay at pickup, and buy in all 50 states in any condition, whether the machine is running production, sitting idle or needing work. A single G350 and a full production cell of G-series universals get the same terms, and each unit in a multi-machine pull still gets scoped on its own control, hours and condition.
Have This Ready Before You Call, Whatever the Vintage
Model plate number, year, spindle hours if tracked, condition, tooling and automation, and control type are enough to start. Photos of the control screen and the work envelope speed a first number but are not required. On an older saw the data plate model number is usually enough on its own, since there is no control generation to ask about. The listings that carry a year run from 1969 to 2026, so this hub holds machines from the current model year sitting alongside units built more than fifty years ago. Factory documentation on units that old is thin, so a photo showing the footprint and how the machine sits in the shop does more for the rigging plan than a catalog spec would. If your model does not appear anywhere on this page, send it anyway. We buy Grob across every product line, and a number typically comes back within 24 to 48 hours.
Common questions
How do I sell a used Grob machine?
Send the model, year, spindle hours, condition, control type and any tooling included. We evaluate it, send an offer, then handle rigging and freight and pay at pickup.
Does Grob buy back used machines?
Grob offers a factory trade-in and buy-back path, but it requires purchasing a new machine. MTE buys your used Grob outright, with no new-machine purchase attached.
Who buys used Grob machines?
Machine Tool Exchange, a division of Superior Machine and Tool since 2012, buys them directly. We are not a listing service or an auction platform.
What is my used Grob machine worth?
It turns on model, year, spindle hours, condition, control generation and automation package. A band saw is scoped on different terms than a universal. Send the details and we will price it.
Do you buy Grob machines with Siemens Sinumerik controls?
Yes, including 840D sl machines, where control generation carries real weight. The 4V and NS band saws here predate that control entirely, and we buy those too.
My Grob is not a G-series machining center. Do you still buy it?
Yes. This book runs well past the G-series: 4V and NS band saws, 5 horizontal boring mills, 4 lathes and 3 grinding machines. We buy every Grob product line.
Who pays for rigging and freight, and when do I get paid?
We do. MTE covers rigging, crating and freight at no cost to you, in all 50 states, and pays at pickup, not on net terms afterward.
Thinking about selling Grob Machines?
A G550 five-axis universal and a 4V-18 band saw are two different conversations, and this page has now covered both. Whichever one is on your floor, Jason Puuri scopes it himself on control, hours and condition instead of running a formula, and a number typically comes back within 24 to 48 hours. Call (517) 220-4400 or send the details through the offer form at /sell-your-cnc-machine/. No listing fees, no broker fees.
