CNC Lathes & Machining Centers
Used Okuma LB3000: Sell or Buy at Auction
Okuma is a premium Japanese machine tool builder known for high-precision lathes, grinding machines, and machining centers. The Okuma OSP control system is proprietary and highly regarded for its user-friendly interface and thermal compensation technology. Okuma machines are common in aerospace, automotive, and precision manufacturing.
The Okuma LB3000 is a horizontal CNC turning center positioned in the middle of Okuma's LB series, above the compact LB2000 and below the larger-capacity LB4000. In its base form it is a two-axis lathe, and it ships standard with an 8-inch hydraulic chuck (10-inch optional) and a bar capacity of roughly 2.5 inches, which puts its maximum turning diameter in the low-to-mid teens of inches (about 340 mm). Every LB3000 runs Okuma's proprietary OSP control, and machines from the EX and EX II generations are the ones most often seen on the used market, frequently ordered with a sub-spindle, a live-tooling turret, and C-axis capability for done-in-one turn-mill work. That mid-diameter envelope makes it a fit for precision machining shops, automotive Tier 1 suppliers, and general job shops that have outgrown smaller bar-fed lathes but do not need LB4000-class capacity. The OSP interface's loyal following among experienced CNC machinists keeps used demand steady. KD Auctions sees this Okuma lathe move briskly at auction, with active bidding drawn from a network of 500,000+ industry contacts across precision manufacturing and job-shop channels.

Frequently Asked Questions
What is my Okuma LB3000 worth at auction?
There is no fixed figure. Value tracks the machine's age, spindle hours, and overall condition, which OSP control generation it runs, and how it is tooled: chuck size, whether it carries a sub-spindle, live tooling and a C or Y axis, and any bar feeder. KD Auctions provides a free AMEA-accredited, USPAP-compliant appraisal covering both orderly liquidation value (OLV) and forced liquidation value (FLV), so you know where your LB3000 stands before you decide how to sell.
How does the LB3000 compare to Okuma's LB2000 and LB4000?
It sits squarely between them. The LB3000 offers more swing and chucking capacity than the LB2000, which is built for smaller-diameter bar work, while staying lighter duty than the LB4000, which takes larger shafts and heavier stock. That middle ground is why shops turning mid-diameter flanges, shafts, and housings target the LB3000 specifically. To sell one, call KD Auctions at 480.455.3910. A managed auction typically runs 6 to 10 weeks from engagement to payout, with onsite dispatch scheduled within 48 to 72 hours, and commission is tailored to the engagement and quoted upfront, so most sellers pay nothing out of pocket.
