Remanufacturing, Rebuilding, Retrofitting

The 3 R’s – Retrofitting. Rebuilding, and Remanufacturing.

In the world of machine tools these three terms are often used interchangeably but they are distinctly different. Let’s take a moment to define what we mean by these terms.


“To furnish with new or modified parts or equipment not available or considered necessary at the time of manufacture”

In machine tools this most commonly refers to the electrical part of the machine. This includes the control, whether CNC or PLC, and the motors and drives.


“To restore to a previous state”

Machine tools wear out over time. Rebuilding of a machine tool will bring it back to its original design specification. At DiPaolo, we reference the original accuracy charts of the machine in our quotes and in our acceptance criteria.


“To manufacture into a new product”

In essence, a combination of retrofitting and rebuilding, we take the best parts of ‘old iron’ and marry it to new state of the art technology.

Which one is right for me?

There are many factors to be considered when deciding which of the 3 R’s is right for you. Our team of skilled professionals will help you make the correct choice. Factors to be considered:

  • Cost of new vs rebuilt
  • Lead time
  • Down time
  • Cost of new foundation
  • Cost of new tooling
  • Resale value
  • Customization

What controls do you offer?

We have a wide variety of experience with different control manufacturers and we’ll always offer our opinion on which control is right for your application.

Sample Projects

72″ Heyligenstaedt Lathe

A heavy duty Heyligenstaedt lathe that swings 72” x 26’ between centers. This machine was remanufactured and is in use daily in the production of parts for gas turbines. The application is very heavy duty and very precise. We were able to deliver this machine in 4 months for less than 40% of the cost of new. The machine is equipped with SIEMENS 840D SL CNC control, motors, and drives.

Schiess 4KE400/810 VBM

Converted from manual to CNC when it was remanufactured this SCHIESS vertical boring mill was built for producing water turbines.  We increased the swing, cast a new saddle, and designed and built new ballscrew transmissions.  The machine was equipped with a FANUC 31iA5 CNC control, motors, and drives.  We sourced this machine in Europe.  The total investment was 50% the cost of new and the lead time was less than half.

G&L VTC 60

This Giddings & Lewis VTC 60 is equipped with a two pallet system and a multi-level ATC.  Completely remanufactured at DiPaolo with new FANUC 31iB CNC control, motors, and drives this machine was returned to ‘like new’ condition.  Our applications department developed new custom screens for the ATC and pallet management.  The fourth project we delivered for this industrial compressor manufacturer was a huge success.  The customer reports that it was less than 50% the cost of new.
