MILLTRONICS ML-40 – 2008
USED MILLTRONICS ML-40 – 2008
The 2008 Milltronics ML-40 is a large-capacity CNC toolroom lathe designed to provide the flexibility of both manual and CNC operation in a single machine platform. Manufactured by Milltronics USA, Inc., the ML-40 is part of the company’s respected ML Series, which is widely used by job shops, maintenance departments, educational facilities, and prototype manufacturers. The ML-40 stands out for its generous swing, long-bed options, conversational programming, and operator-friendly design.
Unlike conventional production lathes, the ML-40 is engineered for versatility. Operators can use electronic handwheels for manual-style machining or run full CNC programs using the Milltronics Centurion control. This makes the machine ideal for low- to medium-volume work, repair operations, and custom machining where frequent setup changes are common. Typical 2008 configurations feature a 40-inch swing, 80-inch distance between centers, a 6-inch spindle bore, and a 35 HP spindle motor with speeds up to approximately 900 RPM on large-bore versions. Smaller-bore configurations may offer higher spindle speeds.
The ML-40 is built on a rigid flat-bed cast iron platform with hardened and ground box ways for excellent stability during heavy roughing and precision finishing. Common equipment includes an 8-station electro-mechanical turret or quick-change tool post, hydraulic chuck, programmable tailstock, flood coolant, and chip conveyor.
Industries that use the MILLTRONICS ML-40 include aerospace, automotive, oil and gas, agricultural equipment, mold making, maintenance and repair, and general contract machining. Typical parts include shafts, rollers, bushings, hydraulic cylinders, flanges, and custom one-off components.
The 2008 model remains highly desirable because of its intuitive conversational control, dual manual/CNC capability, and cost-effective operation. For shops seeking a versatile large-capacity turning solution, the used MILLTRONICS ML-40 offers excellent productivity and outstanding value.
