CNC Machining Centers & Lathes
Used Mori Seiki SL-25: Sell or Buy at Auction
Mori Seiki was one of Japan's most respected machine tool builders before merging with Germany's Deckel Maho Gildemeister to form DMG Mori. Vintage Mori Seiki lathes, machining centers, and multi-tasking machines are highly regarded for build quality, the MSX and Fanuc controls, and long service life. Pre-merger Mori Seiki machines retain strong auction demand.
The Mori Seiki SL-25 is a two-axis, slant-bed CNC turning center built for mid-size production work, with roughly 21 inches of swing over the bed and a maximum turning diameter in the 12 to 13 inch range. It runs a hydraulic three-jaw chuck, commonly 8 to 10 inches depending on how the machine was configured, and indexes tools through a 12-station turret under Fanuc-based control: early units shipped with a Fanuc 6T, while later machines carried Mori Seiki's own Fanuc-based MSC control. Spindle speeds top out in the 3,500 to 4,000 rpm range, enough to move between bar-fed and chucked work without stepping up to a larger lathe. Job shops and contract turning operations seek out the SL-25 because its heavy slant-bed casting and hardened box ways stay rigid deep into the part run, holding size well past the hour counts that retire lighter-duty machines, and rebuilders like it as a clean retrofit candidate since the mechanicals routinely outlast the original control. When KD Auctions lists a used Mori Seiki SL-25, bidding draws on the brand's loyal machinist following and our network of 500,000+ industry contacts, and clean, well-tooled examples with documented maintenance move fastest.

What is a used Mori Seiki SL-25 worth at auction?
Auction value for a used Mori Seiki SL-25 comes down to its age, spindle hours, overall mechanical condition, which control it carries (an early Fanuc or a later Mori Seiki unit), and the tooling and chucks included with it. KD Auctions provides a free AMEA-accredited, USPAP-compliant appraisal that reports both orderly liquidation value (OLV) and forced liquidation value (FLV), so you know exactly where your machine stands before you decide to sell.
How does the SL-25 compare to other Mori Seiki SL-series lathes?
The SL-25 sits in the middle of Mori Seiki's SL lineup: larger in swing and turning capacity than the smaller SL-1, SL-2, and SL-3, but well under the heavier SL-35, SL-45, and SL-75 turning centers. That mid-size envelope makes it a common fit for job shops and Tier 1 automotive suppliers running both chucked and shaft work without the floor space or cost of a bigger machine. To sell an SL-25, call KD Auctions at 480.455.3910: a managed auction runs about 6 to 10 weeks from engagement to payout, commission is tailored to the engagement and quoted upfront, and most sellers pay nothing out of pocket.
