What to Consider When Buying a Used Doosan Puma 400B

There is no debate about the Doosan Puma 400B’s efficiency, but before buying one, you should be considering a few things. The first one is the machine’s condition. Make a thorough inspection and see whether there’s wear on guideways, the spindle, and turret components, and only buy if it ticks your quality checklist. Maintenance history is another smart way to know how well the machine has been maintained. Ask for its service records and make an informed decision. Tooling compatibility is as important as the overall quality. Before buying, you have to make sure the turret and tailstock configuration match your existing setup.

Also, as a side note, if possible, don’t forget to actually make the machine and check yourself if its performance match with the selling description.
