Car owners often face a situation where the technical condition of the wheels remains ideal, but the appearance leaves much to be desired. Small chips from gravel, deep scratches after contact with curbs and faded metal can spoil the impression even of an expensive sports car. It is in these cases that help comes to the rescue. diamond-drive - a procedure that allows the products to return to the factory gloss and geometric accuracy.
This process doesn’t just hide defects, it actually removes a microscopic layer of damaged metal, exposing a clean, shining surface. Unlike conventional painting, which only masks the problem, machining restores the original structure of the front part. Cast discs After such a procedure, they look like new ones, and their value in the secondary market can significantly increase.
Many motorists mistakenly believe that recovery is possible only in the factory, but modern mobile complexes and specialized studios allow you to perform the work qualitatively and in garage conditions. The main thing is to understand the essence of the technology and not try to save on equipment, since poor-quality processing can lead to an imbalance of the wheel. Let’s look at what this process is in detail.
The essence of technology and equipment used
The method is based on the use of a specialized CNC lathe (numerical program control). Diamond cutter, made of superhard materials, with high accuracy removes the thinnest layer of aluminum from the surface of the disk. The spinel speed and the tool feed are calculated by the computer, which eliminates the human factor and guarantees perfect smoothness.
The process is similar to the work of a jeweler, where every tenth of a millimeter is important. The machine fixes the wheel in the center, eliminating any beats that may have occurred during operation. This allows not only to update the appearance, but also to correct minor geometry disturbances that affect the balancing. Diamond duct technology It is especially effective for discs with polished front.
Before contacting the service, be sure to check whether they use CNC machines or hand lathes - the final surface quality and the absence of radial beats directly depend on this.
It is worth noting that the depth of removal of metal is minimal and usually does not exceed 0.5 mm per pass, which is safe for the strength of the structure. However, before the start of work, the master necessarily carries out a defect, checking the disk for cracks. If the metal structure is broken, machining may be contraindicated, as thinning of the walls in critical areas is unacceptable.
When a leak is needed: Diagnostics of defects
To understand that your wheels require professional intervention, you can by a number of visual signs. Most often, owners turn to the service after the winter season, when the roads are treated with reagents, and the asphalt is hidden under a layer of dirt and ice. Deep scratches And scuffling is not only an aesthetic problem, but also foci of future corrosion.
Particular attention should be paid to combined-coated discs, where polished aluminum is adjacent to painted sectors. Galvanic damage to such surfaces leads to rapid oxidation and the appearance of whitish plaque, which cannot be removed by a conventional sink. In such cases diamond-drift This is the only way to restore uniformity of the coating without full repainting.
⚠️ Warning: If you notice a vibration of the steering wheel at high speeds, this may indicate not only poor balancing, but also a violation of the geometry of the disk. The duct can correct minor deviations, but serious deformation requires editing on a hydraulic machine.
In addition, the procedure is relevant for preparing discs for sale or for recovery after careless parking. Even if there is little damage, the contrast between the old, worn surface and the new areas will be striking. Uniform removal of the metal layer over the entire area of the front part ensures the perfect match of shades and texture.
Stages of reconstruction
The recovery process takes several hours and is divided into strictly defined stages, the violation of which is unacceptable. First, the wheel undergoes thorough washing and cleaning of dirt, bitumen and old layers of varnish in the areas of damage. And then there's the important stage. defectIn this case, the master assesses the residual thickness of the metal and looks for microcracks.
☑️ Checklist of the stages of the flow
After preparation, the disk is installed on the machine, where the metal is removed directly. The computerized system controls the depth of the cut, ensuring uniformity of the treatment. Upon completion of the mechanical part, the surface is polished with special pastes, and then coated with several layers of durable varnish, which protects aluminum from oxidation.
The final stage includes drying in the chamber and a quality control of the coating. It is important that the varnish lay flat, without leaks and bubbles, otherwise all the work will go to waste. The quality lacquer coating ensures that the updated disc will retain its shine for several seasons, despite the aggressive impact of the road environment.
Comparison of Disk Recovery Methods
Choosing the method of restoration, many are lost between full painting, polishing and diamond duct. Each method has its pros and cons, as well as different costs. Painting allows you to change color and hide serious defects, but it hides the natural texture of the metal and often looks less noble.
Polishing, in turn, is only suitable for surface scratches and is not able to remove deep furrows or restore geometry. Diamond processing It occupies an intermediate position, combining mechanical restoration of shape and preservation of metallic shine. It is the perfect choice for factory-polished discs.
| Parameter | Painting. | Polishing | Diamond duct |
|---|---|---|---|
| Rebuilding geometry | No. | No. | Yes (partial) |
| Preservation of metal texture | No. | Yes. | Yes. |
| Resistance of coating | Tall. | Low (no varnish) | Tall (with varnish) |
| Cost | Medium | Low. | Tall. |
When choosing a method, the disc material should also be considered. For forged products, which often have a complex texture, the duct may not always be applicable in full, whereas for classic casting it is a standard procedure. Painted discs can also be welded, but in this case, a subsequent painting of the treated surface in the color of the rest of the part will be required.
Caring for disks after processing
After an expensive procedure, you want the result to please the eye as long as possible. The main enemy of the refurbished coating are aggressive chemical agents that are sprinkled on roads in winter, and automatic washing with their hard brushes. Protective varnish, applied in the process of flow, resistant, but not eternal, and requires careful treatment.
It is recommended to wash the wheels with a soft sponge using neutral shampoos designed specifically for aluminum alloys. Avoid using acid cleaners or aggressive chemicals to remove bitumen, as they can damage the lacquer layer and cause clouding of the polished surface. Regular washing will prevent the accumulation of brake dust, which, when heated, can eat into the coating.
⚠️ Warning: Never use abrasive sponges or metal brushes to clean polished discs. Even micro scratches from the stiff bristles will eventually lead to loss of shine and clouding of the surface.
An additional measure of protection can be the application of ceramic coating or special wax for discs after each second or third wash. This will create an additional hydrophobic layer that will repel dirt and water, making it easier to care for. Regular examination surface for the appearance of new chips will allow you to paint the damage in time and prevent the development of corrosion under the varnish.
Cost of work and economic feasibility
The price of a diamond duct varies depending on the diameter of the disk, the degree of its damage and the pricing policy of the service. Usually the cost is per unit and may or may not include tire removal/installing and balancing. For the popular R16-R18 diameters, the price is quite affordable compared to buying a new kit.
The economic sense of the procedure is obvious: the cost of four new original discs can be several times higher than the price of their full restoration. Even with the cost of percolation and subsequent balancing, you get a visually new product for fraction of the price. This is especially true for owners of premium cars, where the price of a set of discs is estimated at thousands of dollars.
Does the leakage affect the guarantee?
Automakers often point out that any mechanical interference with the design of the wheels can cause a warranty to be denied. However, if the duct is made qualitatively, without violating the structural integrity and removing a more permissible layer of metal, it rarely becomes a real cause of failure. However, for new cars on warranty, this risk is worth considering.
In addition, refurbished drives increase the vehicle's liquidity when sold. The customer always pays attention to the condition of the wheels, and the ideal wheels can be the decisive argument in your favor. Investment in the appearance of the machine often pays off when it is implemented, allowing you to quickly find a buyer and justify a higher price.
Diamond duct is an investment in the appearance and liquidity of a car, which pays off due to significant savings compared to the purchase of new original discs.
In conclusion, it is worth saying that high-quality ducts require a professional approach and expensive equipment. Do not chase the lowest price, as savings during the preparation or use of cheap varnish can lead to a rapid clouding of the disk. Trust your wheels only to proven craftsmen with positive reviews and portfolios.
Can I make a diamond on a forged disc?
Technically, this is possible, but it requires special care. Forged discs have a different metal structure and often thinner walls. The master must accurately assess the residual thickness, so as not to disturb the strength characteristics. In some cases, only polishing is recommended for forging without removing a significant layer of metal.
How many times can you run the same disk?
The number of possible procedures is limited by the thickness of the metal. Usually, the disk can be threaded 2-3 times during its entire service life, removing the minimum required layer each time. After each leak, the thickness of the walls is necessarily monitored.
How long does the varnish last after the leak?
When observing the technology of application and use of high-quality materials, the lacquer coating lasts from 2 to 5 years. The service life depends on the operating conditions, frequency of washes and the presence of protective treatments (wax, ceramics).
Does the duct remove the disk beat?
The duct can eliminate small irregularities of the working surface caused by wear or small deformations. However, if the disc has a serious geometric deformation ("eight" or "egg"), first you need to edit on the hydraulic machine, and only then - the duct to restore the appearance.
