Rebuilding, re-furbishing or upgrading machinery is an exacting and painstaking process. This is where our dedicated team of professionals really excel.

It starts with carefully dismantling, measuring and recording the vital information and data. Each component is thoroughly checked and faulty or sub-standard parts are replaced where necessary. With all our rebuilding projects, alignment and positioning are the keys to success. All surfaces are cut flat and parallel and in many cases, hand scraped to restore perfect alignment and positioning.

Then, after this process is complete, we begin the restoration. This is where our experience of almost 50 years in this industry really comes to the fore. Using our state of the art measuring equipment, we carefully restore your equipment to repeatability tolerances of +/- 0.000001".

At Grout & Darlington, "perfection" is our middle name and our long list of satisfied clients is testimony to our attention to detail and caring attitude.

A complete machine tool rebuild involves the restoring of a machine's mechanical systems to like new condition while retaining the original control and or electric system, saving up to 80% of the cost of a new machine!

If your machine has a later model CNC control and drive system but production has been beating it to death three shifts a day, seven days a week, a complete machine rebuild to BL standard specifications can return the machine to original functionality and dependability.
