CNC retrofits provide state-of-the-art control technology, but they assume that the base machine structure is in good mechanical condition. Where machines have lost their accuracy and/or are breaking down on a regular basis, EES offer a machine refurbishment service.

The extent of the refurbishment varies from machine to machine; this ranges from a partial overhaul, to correct known faults or inaccuracies, to a full machine rebuild where the machine is stripped to component level, slideways reground to restore accuracy/alignment, damaged and worn parts refurbished or replaced and the machine rebuilt to manufacturers original tolerances and in accordance with BS 4656.


  • Increased machine utilisation, through reduced downtime
  • Increased accuracy
  • Reduced scrap
  • Reduced maintenance costs
  • Machine Refurbishment is a fraction of the capital cost of an equivalent new Machine


Below is a list of frequently asked questions and answers regarding Machine Refurbishment with Electron Engineering Services. Select a section heading and read the information listed to get your answers. Have another question? Call us on 01422 327523.

  • Is my Machine suitable for refurbishment?

    All machines can be refurbished but you have to consider the cost of refurbishment against a new machine. High Accuracy, High Specification or Large Capacity Machines provide the best opportunities for significant cost savings when compared with buying new.

  • How much will a Refurbishment cost?

    The cost of refurbishment depends largely on the scope of work required, coupled with the size & complexity of the machine (i.e. number of axes, auto tool loading, pallet loading, etc). However, EES will be pleased to visit your works, view the machine in question, discuss your requirements & expectations, and provide you with a detailed quotation, completely free of charge.

  • How long does a refurbishment take?

    The downtime for refurbishment & retrofit depends largely on the extent of refurbishment, coupled with the complexity & size of the machine, but, purely as an example, a full refurbishment/ retrofit on a CNC Vertical Borer, such as a Webster & Bennett, will take typically 20/22 weeks.

  • Can my machine be re-engineered to CNC?

    Increasingly, EES are being asked to re-engineer older, conventional, machines to convert them to CNC, thereby enhancing capabilities, accuracy and performance and further increasing machine utilisation. EES will be pleased to visit your works, view the machine in question and provide you with an informed assessment as to the suitability of your machine, for conversion to CNC, completely free of charge.
