What to Look for When Buying a Used L&L Lathe
L&L builds heavy, rigid lathes intended for large and demanding turning work, so used-machine inspection focuses on the items that carry that load. Here is what to check before buying.
Inspect the bed, ways, and saddle for wear. L&L flatbed and heavy-duty lathes ride on wide hardened or hardened-and-ground ways. Check for scoring, galling, and uneven wear near the headstock where most cutting happens. Run the saddle and cross-slide the full length of travel and feel for tight or loose spots. On large machines, way wear is the single biggest driver of accuracy loss, so a machine that has been kept clean and well-lubricated is worth more. Ask about the central or automatic lubrication system and whether it has been maintained, since starved ways wear quickly on heavy machines. A test cut, where possible, tells you more than any spec sheet about how the bed holds geometry under load.
Check the headstock, spindle, and chuck. Measure spindle runout and listen for bearing noise across the full speed range. On big-bore and oil country models, confirm the through-bore is clean and undamaged and that the steady rests and chuck jaws are present and serviceable. Test gear changes and verify the spindle holds speed under simulated load.
Verify the tailstock, ballscrews, and axis drives. On a heavy lathe the tailstock takes real abuse, so check quill extension, alignment to the spindle centerline, and clamping. Test each axis for backlash and confirm the ballscrews and servo drives move smoothly without lag or chatter.
Identify the control and confirm it powers up. Confirm the CNC control boots, runs a program, and that the operator panel, handwheels, and feed overrides all function. Matching the control to your shop's existing expertise reduces training time and keeps the machine productive from day one.
L&L Lathe Series
LL Series (Flatbed CNC Turning & Boring)
The LL series is L&L's flatbed CNC turning and boring lathe, built on a wide, heavily ribbed bed for rigidity under heavy cuts. The open flatbed layout makes it well suited to large-diameter and long workpieces that will not fit a slant-bed machine, and the platform supports turning and boring in a single setup. It is a workhorse for large shafts, flanges, and boring work and is among the more commonly traded L&L machines on the used market.
LS Series (Heavy-Duty CNC Boring Lathes)
The LS-C, LS-S, and LS-U heavy-duty CNC boring lathes are engineered for large-diameter, long, and heavy workpieces. With large spindle bores and robust headstocks, these models are popular in oil and gas, steel, and power-generation shops where parts are big and tolerances must hold under load. The large through-bore makes them a natural fit for oil country tubular work, while the heavy headstock and drive train handle the deep, interrupted cuts common in steel-mill roll and flange machining.
LFM & LFS Series (Large CNC Lathes)
The LFM and LFS large CNC lathes extend swing and length capacity for oversized rolls, flanges, and shafts. These machines suit heavy-industry users who need maximum capacity in a single rigid platform.
LLA, LLB & LLS Series (Multi-Axis Turn-Mill)
The LLA, LLB, and LLS multi-axis turning-milling machines combine turning with live tooling and additional axes, allowing complete machining of complex parts in fewer setups. They are a good fit for shops consolidating turning and milling operations onto one machine, which reduces part handling, cuts down on fixturing, and improves repeatability on parts that would otherwise move between several machines.
LC, LD, TA, MA & Manual Lathes
The LC and LD precision CNC lathes handle smaller, high-accuracy turning, while the TA and MA standard lathes and the LA and A manual lathes cover conventional and entry-level turning. Together they give buyers options from manual job-shop work up through full CNC production.
How to Sell Your Used L&L Lathe
L&L lathes hold value because heavy, rigid turning capacity is always in demand, and large oil country, boring, and flatbed machines are expensive to replace new. The LL, LS, and LFM platforms are especially sought after.

Frequently Asked Questions About Used L&L Lathes
Are used L&L lathes reliable?
Yes. L&L builds heavy, rigid lathes to recognized international standards including ISO-1708 and VDI-3441, and the company has earned national recognition for innovation in CNC lathe design. A well-maintained used L&L lathe can deliver many more years of productive heavy turning.
What CNC control does L&L use?
L&L lathes are most commonly equipped with Fanuc CNC controls, with Siemens available depending on the model and how the machine was specified. Conventional and manual models in the lineup use simpler NC or manual controls. Confirm the exact control on any specific machine before purchase.
What should I inspect before buying a used L&L?
Focus on the bed and way wear near the headstock, spindle runout and bearing condition, tailstock alignment, axis backlash, and a full power-up test of the control. On big-bore and oil country models, also check the spindle through-bore, steady rests, and chuck.
What L&L models hold their value best?
The LL flatbed turning and boring lathes, the LS-series heavy-duty boring lathes, and the LFM and LFS large lathes tend to hold value well because large, rigid turning capacity stays in demand. Call (844) 478-8181 for current valuations.
Where are L&L lathes manufactured?
L&L Machinery Industry Co., Ltd. designs and builds its lathes in Taichung, Taiwan, and exports to more than thirty countries, including the United States and Canada.
What industries use L&L lathes?
L&L machines are widely used in oil and gas, steel, wind power, marine, power generation, transportation, and aviation, anywhere large shafts, flanges, rolls, and heavy components need to be turned and bored.
