MILLTRONICS ML22
USED MILLTRONICS ML22
The Milltronics ML22 is a CNC flat-bed combination lathe designed for toolrooms, job shops, repair facilities, prototype machining, and low- to medium-volume production. Unlike a conventional production-only CNC turning center, the ML22 combines CNC operation with manual and teach capabilities, giving machinists considerable flexibility when handling custom parts, repair work, short production runs, and one-off components. Milltronics describes its ML Series as combination lathes intended for toolrooms and job shops, with options including automatic turrets, live tooling, C-axis capability, steady rests, follow rests, and chip conveyors.
The ML22 is a relatively large machine within the ML Series. Typical ML22/60 specifications include approximately 23 inches of swing, 13 inches of X-axis travel, 63.5 inches of Z-axis travel, a 3.22-inch spindle bore, 2,000 RPM maximum spindle speed, and a 24/15 HP two-speed spindle motor. The machine can be configured with an 8-station automatic turret and tailstock.
One of the ML22’s major strengths is its heavy-duty construction and long-bed capability. The ML22/60 uses a rigid box-way design and is capable of machining long shafts, bushings, threaded components, hydraulic parts, couplings, and other extended-length workpieces. A used ML22 can therefore be particularly attractive to shops that need more turning capacity than a compact CNC lathe can provide without investing in a much larger production turning center.

INDUSTRIES THAT USE MILLTRONICS ML22
The Milltronics ML22 is well suited to general manufacturing, oil and gas, aerospace, automotive, agricultural equipment, industrial machinery, energy, repair machining, tooling, and contract manufacturing.
Its long-bed configuration makes it especially useful for companies machining shafts, bushings, hydraulic components, threaded parts, couplings, sleeves, pins, and other extended-length components.
The ML22’s combination of CNC, manual, and teach operation is also useful in maintenance and repair environments where every job may be different and rapid programming is more important than high-volume automated production.
TYPICAL PARTS MILLTRONICS ML22 CAN PRODUCE
The Milltronics ML22 can produce:
- Long shafts
- Hydraulic cylinders
- Bushings
- Couplings
- Pins
- Threaded components
- Sleeves
- Rollers
- Spacers
- Machine components
- Oilfield components
- Agricultural equipment parts
- Repair and replacement parts
- Custom prototypes
Typical machining operations include turning, facing, boring, threading, grooving, drilling, taper turning, chamfering, and contouring.
With optional live tooling and C-axis capability, appropriately configured machines can also perform additional milling and drilling operations. Milltronics specifically lists live tooling as an option for the ML22 and larger models.
WHY CHOOSE MILLTRONICS ML22
The Milltronics ML22 stands out because it combines large turning capacity, long-bed machining, conversational CNC programming, manual operation, and heavy-duty flat-bed construction in one machine.
The ML22/60 provides approximately 23″ swing, 60″ turning length, 3.22″ spindle bore, 24/15 HP spindle power, and 2,000 RPM maximum spindle speed.
Its conversational control is particularly useful for job shops that frequently handle different parts. Operators can create programs at the machine rather than relying entirely on external CAD/CAM programming.
The machine’s box-way construction also makes it appropriate for heavier cutting and long workpieces. The combination of automatic lubrication, flood coolant, spindle load monitoring, and automatic tooling provides a practical production platform.
WHY BUY USED MILLTRONICS ML22
Buying a used Milltronics ML22 can be an economical way for a manufacturer to obtain substantial CNC turning capacity without the cost of a new large-capacity turning center.
The ML22 is particularly attractive to job shops, repair facilities, toolrooms, prototype manufacturers, industrial equipment manufacturers, oilfield suppliers, agricultural equipment manufacturers, and general contract machinists.
The long-bed ML22/60 can handle workpieces that are too long for many compact CNC lathes, while the approximately 3.22″ spindle bore provides useful bar capacity. The combination of manual, teach, and CNC programming makes the machine flexible for both one-off jobs and repeat production.
Another important advantage is the availability of useful options. Depending on the machine, buyers may find 8-station automatic turrets, hydraulic chucks, tailstocks, live tooling, C-axis capability, steady rests, follow rests, chip conveyors, and tooling packages already installed.
Before purchasing a used ML22, inspect the spindle, spindle bearings, spindle bore, chuck, turret, X/Z axis backlash, ballscrews, box ways, tailstock alignment, control, lubrication system, coolant system, and electrical cabinet.
HOW MUCH DOES A USED MILLTRONICS ML22 COST?
The price of a used Milltronics ML22 can vary significantly depending on year, model configuration, turning length, machine condition, control generation, spindle hours, tooling, turret configuration, and included accessories.
Current market evidence shows a 2006 Milltronics ML22 listed at approximately $19,900, while a used 2007 ML22/60 has been listed at $29,950. Another marketplace currently reports an average listing price of approximately $37,500 for ML22/60 machines.
Based on these market examples, a practical estimated range for a used Milltronics ML22 is approximately $15,000 to $40,000 USD, with ML22/60 machines and newer or better-equipped examples generally commanding more.
For an inventory listing, the following ranges are reasonable estimates:
| USED MILLTRONICS ML22 PRICE RANGE | ESTIMATED COST |
|---|---|
| Older / As-Is Machine | $10,000 – $18,000 |
| Standard Used Machine | $18,000 – $27,000 |
| Good Condition / Production Ready | $27,000 – $35,000 |
| Well-Equipped ML22/60 | $35,000 – $40,000+ |
A basic ML22 in working condition with an older control and average wear may be closer to $18,000–$25,000. A well-maintained ML22/60 with a long bed, 24 HP spindle, automatic turret, tailstock, tooling, and good control could reasonably fall around $25,000–$35,000.
For example, a currently listed 2006 ML22 is priced at $19,900, while a 2007 ML22/60 with a 12″ chuck, 24 HP spindle, 64.5″ machining length, tailstock, and Centurion 7 control was listed at $29,950.
The machine’s actual condition should take priority over asking price. Check spindle runout, axis backlash, box-way wear, turret indexing, chuck condition, tailstock alignment, control operation, lubrication, coolant, and maintenance records before purchasing.
Transportation, rigging, installation, tooling, electrical work, and repairs should be calculated separately from the purchase price.
For a used MILLTRONICS ML22, a $18,000–$35,000 USD estimate is a practical range for many operational machines, while exceptional, newer, or heavily equipped ML22/60 examples can command more.
