OKUMA CADET LNC-8C
USED OKUMA CADET LNC-8C
The OKUMA CADET LNC-8C is a compact, rigid CNC Turning Center designed for precision turning, facing, boring, threading, grooving, drilling, and general production machining. Built with a slant-bed, box-way machine structure, the CADET LNC-8C is well suited for manufacturers and job shops that need a dependable CNC lathe for small- to medium-sized components. The machine is particularly attractive for shops looking for a relatively compact turning center with a 12-station turret, hydraulic chuck, tailstock, and proven Okuma CNC control.
The OKUMA CADET LNC-8C provides approximately 400 mm (15.75″) of swing over the bed, a maximum turning diameter of approximately 250 mm (9.84″), and a machining length of approximately 500 mm (19.7–20″) depending on the individual machine configuration. Typical specifications include approximately 2″ to 3″ bar capacity, an 8″ to 10″ chuck, an A2-6 or A2-8 spindle configuration depending on version, and spindle speeds ranging from approximately 3,500 to 4,200 RPM.
The machine is commonly configured with an OSP-5020L, OSP-700L, or OSP-100L CNC control, a 12-station automatic turret, hydraulic tailstock, automatic lubrication, coolant system, and chip conveyor. Some machines are also equipped with bar feeders, hydraulic 3-jaw chucks, tool presetter systems, and IGF Interactive Graphic Function. Because the CADET LNC-8C was produced in different configurations over its production life, exact control, chuck, spindle, bar capacity, and turning-length specifications should be verified on the individual machine.
The OKUMA CADET LNC-8C is an excellent choice for manufacturers producing shafts, bushings, fittings, hydraulic components, valve components, pump parts, automotive components, sleeves, pins, and other precision turned parts requiring reliable CNC production capability.

WHY CHOOSE OKUMA CADET LNC-8C
The OKUMA CADET LNC-8C is an excellent choice for manufacturers looking for a straightforward, rigid CNC turning center with a relatively compact footprint. Its 15.75″ swing, approximately 9.84″ maximum turning diameter, 12-station turret, and substantial spindle bore provide useful capability for a broad range of production components.
The rigid slant-bed box-way construction gives the machine good support during roughing and finishing operations. The automatic turret allows multiple turning, boring, threading, and grooving tools to remain loaded for production cycles, reducing manual intervention.
The machine’s tailstock also makes it suitable for longer shaft-like components that require additional workpiece support. Depending on configuration, a chip conveyor, bar feeder, tool presetter, hydraulic chuck, and IGF programming system can make the machine even more productive.
WHY BUY USED OKUMA CADET LNC-8C
Purchasing a used OKUMA CADET LNC-8C allows manufacturers to acquire a Japanese-built CNC turning center while keeping the investment significantly below the cost of newer CNC equipment.
Many used machines may include valuable options such as:
- Okuma OSP CNC control
- OSP-5020L control
- OSP-700L control
- OSP-100L control

A currently listed OKUMA CADET LNC-8C is equipped with an OSP-700L control, chip conveyor, bar feed, tailstock, 12-station turret, and 2″ bar capacity, illustrating the type of production package available with used examples.
Before purchasing, buyers should inspect the main spindle, spindle bearings, chuck, drawtube, turret indexing, X/Z-axis movement, ballscrews, box ways, tailstock alignment, hydraulic system, coolant system, CNC control, electrical cabinet, and overall machine geometry.
For an older CADET LNC-8C, spindle hours, alarm history, maintenance records, control condition, replacement-part availability, and evidence of previous crashes should also be reviewed.
HOW MUCH DOES A USED OKUMA CADET LNC-8C COST?
The value of a used OKUMA CADET LNC-8C depends heavily on the machine’s age, spindle hours, CNC control, spindle condition, chuck configuration, turret condition, bar capacity, tailstock, chip conveyor, bar feeder, tooling package, and maintenance history.
Machines equipped with an OSP-700L or later control, hydraulic chuck, 12-station turret, tailstock, chip conveyor, bar feeder, tool presetter, and complete tooling generally command higher resale values.
A current used listing for an OKUMA CADET LNC-8C is offered at $6,950 USD, equipped with OSP-700L control, chip conveyor, bar feed, tailstock, and a 2″ bar capacity. For used-equipment listing purposes, a used OKUMA CADET LNC-8C can typically be expected to sell in the approximately $6,000 to $15,000 USD range, with the actual value depending heavily on condition, spindle hours, control generation, options, tooling, and location.
A well-maintained machine with a healthy spindle, accurate turret indexing, reliable Okuma control, hydraulic chuck, functioning tailstock, chip conveyor, bar feeder, and documented maintenance may command a premium. A machine requiring spindle repairs, ballscrew work, turret repairs, hydraulic work, or control/electrical repairs may sell for considerably less.
