This page is not about cryptocurrency rigs or Bitcoin miners. It is about the CNC machine tools inside mining and mineral processing maintenance shops — boring mills, heavy lathes, grinders, and machining centers that keep mining operations running.
Machine Tool Exchange buys these machines directly from mines, quarries, and mineral processing plants across the United States. Whether your operation is downsizing, closing, or upgrading equipment, MTE will give you a fair, market-based quote within 24-48 hours. No brokers. No auction fees. No consignment. Direct purchase with payment at pickup.

Every mine of meaningful size has a machine shop. These shops keep the operation running by manufacturing replacement parts, rebuilding wear components, and machining custom tooling that would take weeks to source from outside vendors. When a mine downsizes or shuts down, the CNC equipment in that maintenance shop still holds significant value.
MTE buys these machines directly. We are not a listing service, not an auction house, and not a broker. We are the buyer. One call, one quote, one transaction. We handle rigging, crating, and freight at no cost to you, and we pay at pickup.

The connection between CNC machining and mining is not obvious to everyone outside the industry. Mines do not just dig material out of the ground. They run complex mechanical systems that wear out constantly: crushers, conveyors, mills, screens, pumps, and drill rigs. Every one of those systems has components that need to be machined, repaired, or replaced.
That is where the mine’s machine shop comes in. A typical mining maintenance shop runs:
These shops machine components like drill bits, crusher jaws, crusher mantles, conveyor rollers, mill liners, screen decks, shaft sleeves, pump housings, and impellers. The machines that produce these parts are serious industrial equipment, and they hold their value.
Horizontal boring mills are the backbone of most mining maintenance shops. Machines from Giddings & Lewis, TOS, PAMA, Union, and Toshiba are common in these facilities because mining components tend to be large, heavy, and require significant table capacity. A maintenance shop machining crusher housings or large gearbox casings needs a boring mill with serious X, Y, and Z travel.
MTE buys horizontal boring mills in any condition, from any manufacturer. Running in production, sitting idle after a shutdown, or in need of repair. We quote them all.
Mining operations use large engine lathes for turning shafts, rollers, sleeves, and other round components that would be too large or too heavy for a standard CNC turning center. Swing capacities of 30 inches and above are common. These lathes turn conveyor drive shafts, pump shafts, drill rod components, and large-diameter wear sleeves.
Whether your lathe is a manual gap-bed or a CNC flat-bed with a 40-inch swing, MTE will quote it. View our CNC lathe category.
Surface grinders and cylindrical grinders handle the finishing work in mining machine shops. Crusher wear plates, jaw liner surfaces, screen deck rails, and roller bearing journals all require grinding to maintain tight tolerances and surface finishes. Large-capacity surface grinders and heavy-duty cylindrical grinders from mining shops are always in demand on the secondary market.
Some mining maintenance shops run vertical machining centers and horizontal machining centers for more complex work: multi-axis tooling, hydraulic valve bodies, flotation cell components, and custom fixtures. Five-axis machines are less common in mining shops than in aerospace, but they exist in operations that machine complex geometries in-house rather than outsourcing.
Nearly every mining machine shop has manual mills, manual lathes, drill presses, band saws, and other support equipment alongside their CNC machines. MTE buys these too. When we quote a mining facility, we quote everything on the shop floor.
Have boring mills, lathes, or grinders from a mining operation?
The coal industry has experienced significant contraction over the past two decades. Mine closures and facility downsizing create a steady flow of surplus CNC equipment from coal mining maintenance shops. These shops often contain well-maintained boring mills and heavy lathes that were purchased during expansion periods and still have decades of useful life. If your coal operation is winding down, MTE can quote the entire machine shop in one transaction.
Copper, gold, silver, and other hard rock mining operations run some of the largest maintenance shops in the industry. The components these shops machine — crusher mantles, ball mill liners, large pump casings — require boring mills and lathes with serious capacity. Brands like Giddings & Lewis and PAMA are frequently found in hard rock mining shops. MTE understands the scale of this equipment and has the logistics capability to handle it.
Lithium, cobalt, and rare earth mining is a growing sector with new facilities being built across the western United States. These newer operations often have modern CNC equipment in their maintenance shops. As the sector matures and consolidates, surplus machines from these facilities will enter the secondary market. MTE is already buying from this sector.
Quarries and aggregate producers may not be deep-shaft mines, but their maintenance shops run the same types of equipment. Engine lathes for turning crusher rollers, surface grinders for finishing wear plates, and boring mills for machining crusher housings. These operations run hard and replace components frequently. When a quarry upgrades or closes, MTE buys the shop equipment.
Mineral processing plants — concentrators, flotation circuits, leach operations — have their own maintenance shops separate from the mine itself. These plants machine crusher components, mill liners, screen decks, flotation cell parts, pump impellers, and valve bodies. The CNC equipment in processing plant shops is often newer and more capable than what sits in the mine’s own shop. MTE buys from both.
Selling CNC machines from a mining operation to Machine Tool Exchange is a three-step process. No listing your machines and waiting months. No auction gamble. No tire-kickers. One quote, one pickup, one check.
Contact MTE with your machine details: brand, model, year, condition, and photos if available. For full facility quotes, a basic equipment list with quantities is enough to start. Use the online form, call 800-822-9524, or email us directly.
Our purchasing team evaluates your equipment based on brand, model, age, condition, and current market demand. You receive a transparent, market-based offer. No lowball formulas, no pressure, no obligation.
Accept the quote and MTE handles everything from there. We arrange rigging, crating, and freight at no cost to you. Payment at pickup. For mining sites in remote locations, we coordinate logistics including heavy haul and crane service for oversized equipment.
MTE specializes in CNC machine tools: boring mills, lathes, grinders, and machining centers. For heavy earth-moving equipment like excavators, loaders, and haul trucks, we can refer you to partners who handle that category. If you have CNC machines in your maintenance shop alongside heavy equipment, call us at 800-822-9524 and we will quote the machines we buy.

Most mining maintenance shops run horizontal boring mills for large component work, heavy-duty engine lathes for shafts and rollers, surface and cylindrical grinders for wear components, and large VMCs for complex tooling. Brands like Giddings & Lewis, TOS, PAMA, and Toshiba are common in mining facilities.
Yes. MTE buys entire CNC inventories from plant closures, mine shutdowns, and facility downsizing. One quote, one contact, one pickup. We handle rigging, crating, and freight for the entire lot.
Value depends on the machine type, brand, model year, condition, and current market demand. Boring mills and heavy lathes from mining operations often retain strong value because of their size and capability. Contact MTE at 800-822-9524 for a no-obligation quote within 24-48 hours.
