Before any work commences, a thorough inspection is carried out to assess the condition of the wheel. As the machined surface is only protected by a layer of lacquer, any small chips or scuffs can result in water penetrating beneath the lacquer, causing a ‘spidering’ or ‘milking’ effect. Diamond cutting involves removing a thin layer from the wheels face, so we need to ensure that the wheel has not been too heavily machined in the past, removing too much material from the wheel. Any extensively deep damage may mean that the wheel is too heavily damaged to be ‘re-cut’.
With pre-inspection complete, we de-bead the tyre, begin filling any deep scratches and sand to a smooth finish. Once this has been completed, the next step is to prime the wheel and add a base colour. This process is swift up thanks to our powerful infra-red lamps. After colour has been applied to the wheel, the diamond cutting procedure begins…
Once prepped and painted, each wheels profile is mapped and programmed for machining using the markets latest computer-aided-manufacturing software. The program is developed to generate the tool paths that will precisely re-machine the wheel face, whilst retaining the original wheel profile.
This is where the real action happens and our lathe comes into it's own. Our lathe will remove as little as 0.01” per pass to achieve the highest level of precision. The final pass on our lathes will typically remove as little as 0.008” at a spindle speed and tool feed-rate that will give the ultimate Diamond Cut Finish, without the heavy radial lines found from inferior equipment.
With the diamond cutting process complete, each wheel will undergo a deburring process before it is ready for coating. An anti-corrosive barrier is applied directly to the metal to prolong the wheels life and prevent corrosion.
