WHY CNC ?

Building bespoke racing engines is not easy if you have to rely on other companies to make your parts. That’s why we have invested in CAD CAM software and CNC Milling and Turning machines.
After careful consideration we chose XYZ as the market leader for one off or prototype work to guide us. It’s unlikely we will ever produce high volume parts in our line of business, but we need the same quality of production as bigger companies with the flexibility to make small batches of parts to a very high standard.

Since we got the Mill we have be able to carry out many of the day to day tasks, such as machining blocks for wet liners which used to take a full week on a manual mill, and machining of combustion chambers which is incredibly tricky by hand.

When we took on the Citroen Rallycross engine work for the Doran team we used the Mill to reshape the exterior of the cylinder head removing all the excess material in an effort to save as much weight as possible. The same process is used for the cam carriers and new cam covers were made to suit.

 

So from drawings like this:

We make parts like these:

We can offer our customers a bespoke design to manufacture process all performed on site at JGE.

A selection of parts we make is listed below – all of which are available in our shop. If you have something broken, missing or needing a redesign, our CNC team will be happy to help even if it’s just a single part, please call or e mail with your queries.
