What is disk editing and why is it needed?

It is enough to drive into a hole (which is inevitable in winter), catch the wheel on a curb, or drive too quickly through the release threshold and damage the finished rim. Is it possible to straighten steel wheels in a cost-effective way? How else can you take care of them?

Straightening your steel wheels will restore driving comfort and safety. So when you feel vibration in your steering wheel, especially when braking, when the car lifts while driving, or when the tires fly off the air, it's worth paying attention to the wheels. It may be enough to straighten them so that all symptoms stop interfering with driving.

How to restore steel wheels

Steel wheels can be easily straightened

Straightening is nothing more than the action of restoring the rim to its original shape. The process consists of eliminating all kinds of irregularities and deformations of the steel wheel that occur during everyday driving. For this purpose, special machines are used, which, due to the elasticity of the alloys, eliminate unwanted changes in shape.

It seems that everything is simple, but it is not. Depending on the alloy rim used for production and how it is made, the straightening procedure and heating temperature vary. Therefore, rim straightening should be done by someone who is experienced and knows what they are doing. Otherwise, you may do more harm than good.

Steel discs can be easily straightened - a broken disc is bent

The basket of straightening services usually does not exceed 900 rubles for one steel rim, but it all depends on both its size and the degree of damage.

Rolling and painting of discs

Both steel and cast car wheels can be repaired. The only difference is the price of the work. But a stamped rim is much easier to repair, since the steel is more malleable. But a cast one is more difficult to fix, and severe deformations on it cannot be removed. If you plan to completely restore the disc, then in addition to rolling it will also require painting.

After the deformed rim is returned to its original shape, it is time to prepare it for painting. In auto repair shops, sandblasting is most often used for this type of work. It involves cleaning a car wheel from old paint and rust using abrasive particles. Using special equipment, the rim is cleaned to bare metal and re-primed and painted.

Sandblasting

Typically, professionals use powder paints as a painting material. This type of coating is very popular, as it is the most durable and resistant to chemical and mechanical damage.

Painting is carried out with a special gun with an electrostatic effect. Due to the static charge, paint particles stick to the surface of the car disk. The final stage is paint polymerization. It is done in a special chamber at high temperature.

Important!

This type of painting can only be done in a car service; doing it yourself is unprofitable, since the equipment is very expensive. This method allows you to paint the rim not only in one color, but also in several.

Of course, this is not the only coating method; liquid rubber, acrylic paint, and aerosol in a spray can are also used for this purpose. But the powder material is considered the most universal. Rolling metal wheels and painting will cost more than stamped ones. So this needs to be taken into account when planning their restoration.

Restoring steel wheels

If your rims aren't looking their best, might it be better to do a full regeneration with sandblasting and painting? Then they will return to their ideal appearance, which will benefit the entire car.

Sandblasting of steel wheels is carried out in an automatic sandblasting machine. Has a speed regulator that prevents damage to the coating. After this treatment, the rim must also be additionally protected with anti-corrosion liquid.

Steel discs can be easily straightened by rolling the disc on a machine

Then it's time for sanding to remove any scratches or dents, followed by powder coating. There are many colors to choose from, so you can really stand out.

Painting steel wheels starts with a powder coating and then electrostatic powder paint is applied. The part is then sent to an oven where the paint is cured at 180°C. If the chosen color requires it, the rim can also be coated with a clear varnish.

It is worth noting, however, that painting and sandblasting a steel rim costs from 1,700 to 2,700 rubles, which, combined with the cost of straightening, may not be profitable.

Editing a disk yourself

If the damage to the disc is minor, then the car owner does not necessarily need to contact the technicians at the technical center, since the entire procedure can be done personally by the owner of the vehicle in his own garage.

To do this, a car enthusiast just needs to have an absolutely rigid steel base on hand, for example, a vice or just a block, a sledgehammer and a hair dryer or a gas torch, which can easily be replaced with a blowtorch. Next, all steps are done in the following order:

Similar to the previous method, you need to remove the wheel, wash it and inspect it for other defects other than the jammed edge.
The next important procedure is heating the damaged area, which is best done with a hair dryer, since the flame from the burner will hopelessly stain the surface of the product. As the temperature rises, the steel will become more pliable, but at the same time, in everyday conditions, the temperature is still not enough for the material to lose its structure or for any changes to occur in it.
Next, you need to carefully place it on the metal base with the straight deformed part, fix it or hold it securely with your hand. For these purposes, it is best to use the help of another person.
After the product is securely fastened to the steel backing, you need to take a sledgehammer and apply several precise blows to the bent area to straighten it.
The procedure for straightening alloy wheels is completed using a 1-kilogram hammer, which strikes and the remaining deformations are straightened until the wheel reaches the required shape.
Of course, in the process of straightening car rims, the paintwork can be damaged, especially when the product is heated over an open flame. If this is a stamped product, then the car enthusiast can restore it on his own, but in the case of casting, it is still worth contacting a service station where there is a paint booth, and specialists will do the work in compliance with the necessary technology.

Installing the disk before editing

Important!

Despite the straightening of the disk, after manual straightening it will not regain its former geometry, and this will almost certainly cause runout when driving a car at high speed. This means that after such an operation the driver needs to go to a tire shop, where his wheel will be installed on a balancing machine, and if there is no balance, the master will attach additional weights to the appropriate places on the disk.

Expansion of steel rims

... of course, you need to take into account additional costs, and this is not so small. Depending on the size of the rim, the price for a set can be up to 12,000 rubles.

Widening steel wheels for tuning?

Why are the disks expanded? Well, it's a matter of taste. Some say the extension looks better on sports cars or classic cars. They also have the advantage of being able to fit wider tires, which improve traction and make the car better on the road. Others who see such discs have mixed feelings.

Steel wheel flaring starts at 1 inch wide and then at intervals of every 0.5 inch. The next step is to finish the edge so that it looks good after welding. You should also remember to straighten first and then expand.

Making a stand for wheel correction

The stand is intended for correcting uneven stampings and light alloy wheels with your own hands and can be developed at home. Compared to manual processing, it significantly improves productivity and quality of edits.

To make a disk straightening machine, follow this procedure:

install the shaft on the frame, where fasten the universal hub;
Place the product that needs to be fixed on the hub;
secure the bed to the stand. The stand itself is attached to a hydraulic station, which will power the mobile hydraulic cylinder. A tool for straightening discs is mounted on its rod;
control the cylinder using a hydraulic distributor with a pressure reduction valve;
To be able to install the cylinder at any angle relative to the product being repaired, use a pair of movable brackets.

In order for a machine for rolling cast discs to fasten products with different diameters, its hub must be equipped with centering washers of the required diameters (a total of 18 fasteners will be required).

Don't repair steel wheels - it's easier to replace them

Some damage, such as deep scratches, large bends or damaged edges, is not suitable for repair. Rims with heavily raked edges may even break when trying to warm them up.

New steel wheels

In this situation, it is better to simply buy new disks than to play with your own safety. It's worth converting everything because the cost of straightening and painting the rims usually exceeds the new price. So why overpay? It is best to consult a specialist in such a situation and rely on his opinion.

Welding discs.

As a rule, stamped rims rarely suffer from cracks. Most often they bend. In this regard, straightening is more often used for this type of rim than welding. Casting, on the contrary, is often subject to cracks. As a rule, cracks can be detected by professionals and only using special equipment. Argon welding is rarely used for casting. This is explained by the fact that welding is not very productive for disc restoration. The casting has a rather fragile structure that is difficult to reconstruct. Even experienced specialists will not undertake welding, taking care of the safety of the car enthusiast.

Thus, it becomes clear that repairing light alloy rims is a complex procedure requiring expensive equipment and special skills. Steel wheels are less finicky to maintain and can be easily restored. If the structure of a light alloy wheel is damaged, it is imperative to stop operating the vehicle and contact a professional. Timely elimination of the malfunction will preserve the safety of the driver and passengers, and will also extend the life of the vehicle’s chassis and tires. Be vigilant and regularly check the condition of your vehicle's wheels. Good luck in servicing your favorite car.

Hello colleagues! Today I flew right side into a hole (filled with water). I bent the front disc and it flattened almost immediately. I had to put on the spare tire in the rain (as luck would have it, it was deflated and I also had to pump it up). The dent on the inside is decent. Is it possible to straighten it with a hammer or just roll it?

If “rolling”, then where do they do it and on what? Or is this only relevant for cast and forged?

“rolling” turned out to be an ordinary sledgehammer Got it

I'll have to take another look at the rear disc. Although it didn’t go down there, it did.

In general, anyone can skate. On what equipment? Probably not every tire shop has this.

Later I'll replace the disk with a whole one. It's in stock, but it's a long way to get there.

If the shelf (the place where the tire sits) is not bent, then it’s ok. If it weren’t dented, then the tire wouldn’t go flat, IMHO. I'll try to straighten it and pump it up tomorrow.

If it gets bad, I’ll try to take it to the nearest tire shops. Otherwise, you will have to drive 50 km with the spare tire to a garage in the Moscow region.

On the Yauza, on the descent from Preobrazhenka to the Gannushkina embankment, there is a good ride for discs at Tinomontazh! vosmilie:

To everyone who responded, THANK YOU! The problem is solved. :ura1 Using a hammer and a bottle of water. After the first edit and pumping it was poisoning quite a bit. Subsequent light chasing and testing by pouring water into the groove around the disk eliminated all problems. There were no bubbles at all. I pumped it up to normal, set it up, and drove it forward and back with sharp braking (so that the tires sat down without strain). Control measurements after an hour and two did not reveal any pressure drop. I will monitor the first few days (measurements in the morning and evening with an electronic pressure gauge. By the way, a good Chinese thing).

Disadvantages of straightening alloy wheels

If you come across reviews from motorists who have already adjusted alloy wheels, then most likely you will be surprised how many people speak extremely negatively about this procedure. However, there are objective disadvantages that are definitely worth paying attention to.
