Things to Check Before Buying a Used Doosan Puma Series CNC Lathe

When you are looking for a CNC machine like the Doosan Puma models, there is no doubt that you will be flooded with options, even in the used CNC machines market. But the problem is with selecting the right machine for yourself. Among the different options available out there, you can definitely find the right machine for yourself if you do proper research and inspection. So, in this article, we are going to help you out by mentioning the top things to check before buying a used Doosan Puma CNC series machine. 


Top Things to Check When Evaluating a Used Doosan Puma Lathe:

Here are the major things to check before buying a used Doosan Puma turning center that you need to know:

1. Confirm the Specific Model and Year:

The first point that needs to be included in your used Doosan Puma inspection checklist should be the specific model and year of the CNC machine. You should start with the model verification. There are several differences between different puma models, which you should take into account:

  • Footprint

  • Machine features and technologies

  • Tooling capabilities

  • Application Fit.

So, make sure you find out the exact model number, like 3100LY, 400C, or GT3100, and also the manufacturing year of the machine. 

2. Check the Spindle Condition Correctly:

The spindle is one of the most important parts of the CNC machine. Inspecting the Doosan Puma spindle condition is very important for machining products with precision and tight tolerances. First of all, just know the specifications of the spindle, which can be the spindle speed, torque, and power of the machine. 

After that, you need to check the condition of the spindle of the particular machine you are trying to buy. Check the wear and tear on the spindle; extreme wear on the spindle can be alarming. Also, make sure that the spindle is not making growling or whining sounds during machining. 

3. Check Ball Screw Condition and Linear Motion Systems:

One of the major things to check before buying a used Doosan Puma turning center machine should be the ball screw backlash. Over time, ball nets wear down, leading to the creation of backlash. Also, make sure axis movement is smooth with no binding or heavy backlash. 

Make sure ball screws are in proper condition. Replacement of the ball screw can be a costly add on for shops with a tight budget, so it must be factored into pricing discussions if wear is evident. 

4. Check Proper Maintenance Record:

Lastly, one of the major factors to consider when evaluating used Doosan Puma lathe is checking the maintenance record of the CNC machine. Here are some of the major things you can ask:

  • Doosan Puma maintenance history or service history.

  • Oil change intervals for the machine.

  • History of replaced components.

  • OEM or third party service involvement. 

A proper maintenance history is a proper symbol of good ownership practices. 


Also, buying the machine from a trusted platform is an extremely important factor that you need to consider. So, you might like to buy used Doosan Puma CNC machines from MachineStation, a trusted used CNC seller. 

Conclusion:

Used CNC machines can always be a good purchase for those who have a tight budget. So, buying a used Doosan Puma CNC can also be a great choice, and you just need to follow a proper checklist and then make the purchase call.

FAQs:

1.  Are older Doosan Puma models still suitable for current machining needs?

Older Puma models can still be practical depending on their mechanical condition, CNC control version, and the availability of replacement parts and service support in your region.

2. Do all Doosan Puma Series lathes include live tooling and C-axis capability?

Not all Puma lathes are equipped with live tooling or a C-axis, as these are optional features that vary by model and original configuration, making verification through the control essential.

3. How important is maintenance documentation when buying a used Puma lathe?

Maintenance records provide insight into lubrication practices, component replacements, and service intervals, helping buyers understand how the machine was maintained over time.
