Machine Condition
The condition of the used lathe is paramount. Inspect the machine thoroughly, paying attention to wear and tear, rust, and overall cleanliness. Check critical components that are prone to wear and tear like the bed, headstock, tailstock, and carriage for signs of damage. There are specific components related to the type of lathe you are purchasing that should be inspected prior to purchase. An example is the spindle, which is critical to a Lathe machine. You would want to run the spindle at high speed to see if you can catch any odd noises. Another example are the bed ways as they are responsible for the accuracy of the cuts. This part of the machine should be parallel so that the carriage is able to also move with the axis of the spindle. Keep in mind, it is normal to have wear and tear on these components with a used machine. You just want to make sure the wear is not so severe that it would impact the machine’s performance.
Request video and pictures of the machine. This helps give you an idea of the lathe machine’s overall condition before you even set up an in-person visit. A video of the machine running will be essential if you cannot make a trip to see the machine. Ask for maintenance records to get a sense of how well the lathe has been cared for over the years.
Type of Lathe Machine
Understanding the specific type of lathe you need is essential. Most lathe machines that are sold today are CNC, which can be a great asset to your manufacturing facility, as it increases productivity. There are several types of industrial lathes, each designed for different applications:
- Manual Lathes: These are the traditional lathes operated by machinists. They are versatile and often used for simple to moderately complex machining tasks.
- CNC Lathes: Computer Numerical Control (CNC) lathes offer precision and automation. Different types include vertical turret lathes, Swiss lathes, engine lathes, and multi-axis lathes. Your choice will depend on your production needs.
Precision & Tolerance
Does it have a CNC (Computer Numerical Control system? CNC Lathe machines are preferred in the manufacturing industry as they automate jobs and are great for mass production. For CNC lathes, accuracy and precision are vital. Check if the lathe maintains the specified tolerances. Inspect the spindle and cutting tools to ensure they are in good condition.
Machine History
Request information about the machine’s history, including its previous applications and usage patterns. Knowing the kind of work it has done in the past can provide insights into its wear and tear. How old is the lathe and how many hours has it logged? Lathe machines will last decades if they are well taken care of. If the machine has a CNC system, you should be able to keep it up-to-date with the latest software.
Documentation
Ensure that you receive all relevant documentation, including manuals, maintenance records, and any warranties that may still be valid. Maintenance records will allow you to see the service history of the used lathe machine and how well it’s been maintained. This can show you what, if any minor or major repairs have been done on the lathe machinery over its history. This can also put your mind at ease, giving you confidence that the used lathe equipment you’re interested in will perform well for years to come.

Price & Negotiation
Compare prices of similar used lathes for sale in the market to ensure you’re getting a fair deal. Don’t hesitate to negotiate with the seller, especially if you uncover any issues during inspection.
Rigging & Transportation
Consider the logistics of moving the used machine lathe to your facility. Ensure you have the necessary equipment and resources for rigging and transportation. What are the costs to transport this machine to you if need be? You will want to make sure you understand the full cost of purchasing the machine, including the cost of transporting it to your facility.
Compliance with Safety & Regulatory Standards
Before purchasing a second-hand lathe, ensuring the lathe machine is compliant with safety and regulatory standards is of the utmost importance to not only maintain a safe working environment, but to adhere to legal requirements as well. Does the used lathe meet OSHA (Occupational Safety and Health Administration) standards? While CNC lathe machines should not have issues meeting safety regulations, this is something that could come up if it is an older lathe machine.
You’ll also want to verify safety features available on the used lathe and evaluate the lathe’s overall operational safety. Ensure the lathe’s electrical system meets local electrical codes and standards, noise levels comply with local regulations, and that dust and fume control systems are in place, including ventilation and filtration systems, to meet environmental and safety standards. After purchasing a used lathe, establish a regular inspection and maintenance schedule to ensure ongoing compliance with safety regulations. Periodic inspections and maintenance are essential for keeping the lathe safe and operational.
Lathe Machine Inspection
Before purchasing a second-hand lathe, inquire about scheduling an in-person inspection of the used lathe machine. If you’re not well-versed in lathe machinery, consider hiring a professional inspector to accompany you during the inspection. Their expertise can help identify potential issues that may not be apparent to a novice. If an in-person inspection is not possible due to timing or location of the lathe equipment, reach out to the used equipment dealer and request photos and videos of the lathe machine running. Reputable used equipment companies would be happy to send over what you need to ensure you’re confident with the lathe equipment and will be happy long after your purchase.
Conclusion
In conclusion, purchasing a second-hand lathe can be a cost-effective and practical choice for many machining operations. However, thorough research, diligent inspection, and careful consideration of your specific needs are essential to ensure you make a sound investment. No matter what you’re in the market for, a well-maintained and properly chosen lathe can become a valuable asset in your machining arsenal, contributing to your productivity and success.

Looking to buy my first metal lathe | Page 2 | The Hobby-Machinist
of refurbishing a 10" Logan. However, buying an old machine is time consuming (to find a decent one), involves financial uncertainty and results in the lathe becoming the project for some
time, unless you are lucky enough to find a turn key machine. And, you have to like working on old stuff. Many members of this forum fit that description, but the first question
to ask yourself is if you do. If not, then a new machine makes sense. Also, the new machines tend to come with all the usual accessories, and they aren't worn out. What they don't come with is all the other tooling
you'll need. This isn't just cutting tools. If you're new, you have to budget for a wide array of other tools that are not lathe specific, but necessary. Micrometers, dial indicators, taps, dies,
drills, etc., etc., etc. The list is pretty big actually. So, I have to agree with Chipper, $ might get a lathe in the door, but you will need to budget more for all the other stuff you'll need.
I'm NOT trying to discourage you, but just trying to be realistic.
You should resist the temptation to buy a small, cheap lathe and cheap tools as well. If you do, you will quickly become dissatisfied and will want to step up to better stuff, resulting in higher cost
overall. Quality tools are available used on eBay at substantial discounts and almost everyone has sales, if you can wait a bit. Without knowing what you want to make, it's hard to know
how big a machine you'll need. Having said that, a 10-11 inch machine is a reasonable size to start with. Machines above that size tend to be bigger, more expensive, use more expensive
tooling, are heavy and thus more difficult to move and have power requirements that have to be considered. Smaller machines are pretty limited in what they can do, unless you plan on
making small parts.
I don't know anything about the Grizzly, but in that class of machine you could also look at Jet and Precision Mathews. Have a look at the brand specific threads on this forum and
you'll learn a lot about them. Hi Dale,
Inless you are really cramped for space, My guess is the Grizzly you mentioned may end up being to small. Personally, for me, the ideal minimum bed length is 36". 48" is better. This enables you to turn 18" to 24" shafts, axles etc. and have the flexibility to work with longer lengths as needed. I am sure the 22" bed length on the grizzly will be a handicap of sorts, once you get involved in machining. If you can bite the bullet on cost, stepping up to a longer bed will pay off in the long run.
Also I would say your first consideration could be to spend some more time mulling over what kind of lathe work you might want to get into. Some people are very happy with small, 6" CNC style hobby machines and use them to make very small working models of steam engines, miniature aircraft motors, etc. others go the route of building 7 1/2" gauge (1 1/2" scale) locomotives or re building motorcycles and old cars, thus focus on lathes with 12" -14" clearance at the chuck. Yet others find they simply like restoring old equipment and making tooling. So if you decide on a particular interest to start, that will help determine your initial size of machine.
As a rule, a lot of hobby machinists outgrow small lathes and sooner or latter go to a 9", 12" or even 14" machines.
Regardless of your direction, the main thing is - buy a lathe in good condition. New is nice, but expensive. Used is where many more people turn. Badly worn ways, rounded chuck jaws (old worn out chucks), Noisy headstock, worn ridges on the bottom of tailstock, etc will hurt your machining ability and learning curve immensely. So I would encourage you to shop around and look at as many machines as you can. Visit your local live steam club (miniature train people) and ask folks if you can look at their shops. Often club members have stuff for sale and will be open with you about condition. Even take a night class at your local community college. Then keep an eye out for a machine that has been well taken of over the years.
For example, I recently acquired a South Bend Fourteen for $ with very little wear, to replace my first, really worn out big iron machine. Took two years of off and on looking, but the difference in making parts is like night and day.
You are in Ohio! Sort of the center of the universe for machine tools. Craig's list is your friend . Shop around within 500 or miles and iam sure you will find an ideal, nice machine. Happy hunting!!
