When buying a used straight-side mechanical press, the terms "rebuilt" and "reconditioned" have specific meanings:

  1. Rebuilt:
    • Scope: Typically involves a more comprehensive process. It means the press has been disassembled, and all critical components are inspected, repaired or replaced as needed. This often includes major parts such as the gearbox, bearings, and sometimes the frame.
    • Quality: The goal is to return the press to a condition as close as possible to its original factory specifications. This can involve extensive work and can be more costly but usually results in a more reliable machine.
  2. Reconditioned:
    • Scope: This generally refers to a less extensive process than rebuilding. It usually involves cleaning the press, replacing worn parts, and making adjustments to bring it back to a good working condition. It may not include a full teardown and overhaul of the machine.
    • Quality: While still improving the machine's performance and extending its life, the process may not be as thorough as a rebuild. It’s often a more cost-effective option if the machine is in relatively good condition to begin with.

In summary, a rebuilt press typically undergoes a more detailed and thorough refurbishment than a reconditioned one, which can affect the cost and expected lifespan of the machine.
