Diamond cut finish to alloy wheels is growing more in popularity by the car manufacturers year on year. Easily recognised by its shiny mirror polished appearance with fine machining lines being visible, more often in a two tone effect for example black/polished, gunmetal polished etc.
To do this finish as a smart repair or touch up is impossible to achieve without the use of a CNC machine. Here at Wheels UK we have our own state of the art in house Diamond cutting CNC lathe.
The process of diamond cutting is achieved by painting the entire wheel, then a probe digitizes the surface of the wheel to be cut, followed by a diamond tipped cutter that removes a thin layer of metal from the face/lip of the wheel. This is followed by the application of an anti corrosion treatment then finally a very durable powder coat clear lacquer.
Repairs to a Diamond cut wheels can be performed on average 1-2 times as only so much metal can be removed before a wheels strength is compromised and the appearance changes. Should the damage be too deep the wheel will need to be tig welded to achieve a better final result.
Wheels are inspected first checking for buckles or flat spots that would affect the cutting surface, should some be found then our hydraulic wheel straightener can rectify this.
