Machine Tool Exchange buys used CNC and heavy machining equipment directly from mining and minerals operations nationwide. Not the shovels and haul trucks. The machine tools in your maintenance, rebuild, or component shop: the boring mill that lines up crusher frames, the vertical boring mill that faces mill trunnions, the heavy lathe that turns conveyor and pump shafts.
We are the buyer. Not a broker, not an auction house, not a listing site. You get a market-based offer within 24 to 48 hours, we arrange and pay for rigging and freight, and we pay at pickup.

The Machine Tools Inside a Mine Are Easy to Overlook
When equipment gets sold, the mobile fleet gets the attention and the machine shop gets handled last. But that shop exists because downtime is expensive and lead times on large replacement parts are long. Mines, quarries, concentrators, and processing plants keep the work in house: line boring pin bores on a shovel or dragline, remachining a crusher eccentric housing, facing a mill trunnion, turning a conveyor pulley shaft, grinding a hydraulic rod after hard chrome. That takes large, rigid machine tools, and they do not lose their capability the day the site stops producing.
They are also the machines most likely to leave a closing site as scrap, because whoever clears the property prices them by the ton. A scrap buyer values a boring mill by its weight. A machine buyer values it by what it can still hold. That gap is why selling instead of scrapping is usually the better call on heavy iron.
Mining and Minerals Equipment We Buy
Horizontal Boring Mills
Table-type and floor-type machines are the backbone of a mine rebuild shop: crusher frames and eccentric housings, gearbox and pump housings, shovel and dragline structural components, and the large pin bores that come off mobile equipment. Spindle diameter, travels, and table capacity drive the value, so have those handy. See sell your boring mill.
Vertical Boring Mills and VTLs
Anything large in diameter and awkward to hold: crusher heads and bowls, mill trunnions and wear rings, ring gears, slew rings, apron feeder and conveyor pulley components. Table diameter and swing are the value drivers. See sell your VTL.
Heavy-Duty Lathes and Turning Centers
Conveyor pulley and drum shafts, pinion and gearbox shafts, slurry pump shafts and sleeves, hydraulic cylinder rods, and roller work. Long beds and large swing hold value because that size class is scarce. See sell your CNC lathe.
Grinders
Cylindrical, roll, and surface grinders finishing pump and crusher shafts, hydraulic rods after hard chrome or hardfacing, and sealing surfaces. A grinder that held tight tolerances on hardened material is worth more than its size suggests. See sell your CNC grinder.
Machining Centers and Gantry Mills
Wear plate and liner work, chute and screen deck components, weldment machining, and adapter and bracket production. See sell your VMC and sell your gantry mill.
Special Machines and Shop Support
Gundrilling and deep-hole machines for hydraulic cylinder tubes, plus gear hobbers and shapers for drive gears and pinions. See sell your deep hole drill and sell your gear machine. We also take the manual lathes and mills, radial drills, and band saws around them: when we quote a mine shop we quote all of it.
Brands we buy include Mazak, Okuma, Doosan, Toshiba, Giddings & Lewis, and DMG Mori, among many others. If your builder is not listed, call anyway.
This equipment turns up in coal rebuild shops, aggregate and quarry plants, hardrock concentrators doing SAG and ball mill work, cement and lime plants machining kiln and girth gear components, and the independent machine shops in mining regions.
Why Mining and Minerals Operations Sell
Selling is rarely about a worn-out machine. It is a change in the plan around it.
- Site closure or end of reserve life. The orebody is finished or the permit is done, and the whole maintenance shop goes surplus at once.
- Care and maintenance. An idled site still costs money to insure, heat, and secure. Idle machine tools are the easiest item on that bill to turn back into capital.
- Shop modernization. A newer machine is coming and the one it replaces has to be gone before the install date.
- Outsourcing the rebuild shop. Many operations have moved from in-house rebuild to OEM or third-party contracts, which strands good iron.
- Contract completion. A contract miner or maintenance provider finishes a job and the shop that supported it goes away.
- Consolidation or relocation. Two operations become one, or freight on a heavy boring mill out of a remote site does not pencil, so it sells where it stands.
We buy one machine or a full floor on the same process and timeline.
What to Have Ready Before You Call
You do not need an appraisal to start. A short list gets a real number faster.
- The machine facts. Make, model, year, and control, plus the size specs that matter on heavy equipment: spindle diameter, table size and load capacity, travels, swing, and between-centers length.
- Condition, honestly. Running, under power but idle, or down. If it is down, what is wrong and when it last ran. A fault is not a reason to skip the call.
- What goes with it. Chucks, faceplates, steady rests, boring bars, angle plates, rotary tables, and tooling packages. These move the number.
- Records and photos. Maintenance history, any spindle or way rebuild, alignment reports, and photos including the data plate and the control powered up.
- The site reality. This is the part unique to mining. Where the machine sits, whether it is on a grouted foundation or below grade, door and aisle dimensions, in-building crane capacity, road access and weight limits, and whether your site requires contractor safety orientation before anyone comes on property. We arrange rigging and freight for remote and access-restricted sites, but knowing up front changes the rigging plan and speeds the quote.
- Ownership. Confirm the equipment is owned outright, not leased or subject to a lien.
Clearing several machines? One list with models and quantities beats sending them one at a time. Our plant closure and downsizing pages cover full-facility sales.

Step 3: We Rig It, Freight It, and Pay at Pickup
Accept the offer and we take it from there, including heavy haul and crane service for oversized machines at remote sites. No listing fees, no commissions, nothing deducted at the end.
Frequently Asked Questions
Does MTE buy mining equipment like excavators and haul trucks?
Our focus is machine tools: boring mills, lathes, VTLs, grinders, machining centers, and the support machines around them. If you are clearing a site and are unsure what falls in scope, call and we will tell you plainly.
Will you buy a machine that is not running?
Yes. Heavy machines hold value even when they need repair, because the size class is hard to replace. Tell us what is wrong and we factor it in.
Can you work at a remote or access-controlled mine site?
Yes. We buy in all 50 states and coordinate heavy haul, crane service, and scheduling around your site access rules.

Jason Puuri, owner of Machine Tool Exchange, leads the buying side and oversees how MTE values heavy equipment from mining and minerals operations. Machine Tool Exchange is an affiliate of Superior Machine Tools.
Your boring mill lined up crusher frames and your lathe turned conveyor shafts. When the plan around those machines changes, they deserve a buyer who prices what they can still do, not what they weigh.
