What are the tips when using an automobile polishing machine?

The steps for grinding and polishing are as follows:

1. Clean the whole vehicle. Clean the whole vehicle with a paint cleaner with strong detergency, and when using the cleaning agent, you should avoid new scratches caused by particle dust in the grinding.

2. Water sandpaper grinding. For defects such as coarse grains, fine sandpaper marks, flow marks and other defects on the painted surface, wrap 600 water sandpaper in water in a small rubber liner before polishing, and gently polish it until it is smooth (note that it cannot be worn through the paint layer).

3. Coarse and fine grinding. Use a mechanical grinder (electric or pneumatic) plus coarse abrasive paste to coarsely grind the traces of water sandpaper; Then add abrasive paste to polish and polish fine grinding.

4. Polishing. A mechanical polishing machine is used to remove the spin marks left by the coarse abrasive paste with a mirror treatment agent to achieve the effect of mirror polishing of the paint film.

5. Hand glazing. After grinding and polishing, wipe off the grinding and polishing paste, immediately wipe all the polished parts with cotton yarn dipped in varnish wax, and then wipe off the excess varnish wax with dry cotton yarn to make the paint surface bright and dazzling.

In order to make up for these defects, grinding and polishing are usually carried out after spraying, so as to improve the mirror effect of the paint film and achieve the requirements of brightness, smoothness and showiness.

Extended information: Car polishing is the process of car beauty, in the process of waxing, glazing or coating, first polishing the car. Because the glaze coating must be polished first, and it is a finely polished car before it can be made into a mirror.

This is the operation that the glaze must go through. Without polishing, the paint is uneven, and the glaze retention time is very short, and it cannot have the effect of long-term adhesion at all, which is no different from waxing. Of course, according to the situation of the car paint, polishing does not have to be done in all three steps, and new cars often can be restored in one step.

However, the car that has done coarse wax must be polished with medium wax, and the car that has done medium wax must be reduced with fine wax.

At present, the market demand for automobile polishing is very large, but the first aspect is slightly insufficient, especially with core intellectual property rights, there are not many enterprises with excellent product quality, and the industry as a whole lacks brand effect. In the stage of strong demand, there is no doubt that the industry demand is huge and the development prospects are good.

However, how to maintain the health, stability and sustainable development of the industry requires the joint efforts of enterprises in the industry, especially the need to give full play to the fastidious research and development spirit, further improve the production process, reduce costs, truly solve the practical difficulties of customers, strictly control the quality, and provide the most reliable products.

To clean the paint surface, first use coarse wax for slow polishing, polish the paint oxide layer, coarse scratches and uneven parts of the paint surface, and then use fine wax (also called paint reducing agent) for medium speed polishing, and deal with the sun pattern left when the coarse wax is polished, which is basically like this, and now there is also a high-level polishing wax, no need to change the wax, nanotechnology, the wax particles will have a change after grinding, from coarse to fine, to realize the process of changing coarse wax to fine wax, and then do waxing, glaze sealing, coating and crystal plating.

Who knows how many kinds of car beauty items there are, I only know, polishing, asphalt, iron powder, insect corpse, interior cleaning, underwire cleaning, coating, crystal plating, oil film,

It's best to go to the 4S shop, they have special tools! Polishing is a step that does not hurt the primer and does not require insurance, and can be a step for your car to look damage-free, just like waxing!

1. Wash the car.

Before polishing, the car body must be cleaned to remove dust particles to avoid secondary damage to the paint.

2. Grinding. After cleaning the car, the body needs to be roughly sanded, and different sizes of water sandpaper are selected for grinding according to the size of the defects and scratches on the surface of the body.

3. Polishing. After grinding, a suitable polishing machine is selected with polishing wax to finely polish the polished body.

4. Mirror restoration.

After polishing, it is necessary to use a mirror treatment agent to restore the mirror effect of the body, and then wax and glaze.

Tips and methods of car polishing.

When polishing automobiles, it is necessary to grasp the inclination angle of the polishing machine, polish smoothly, clean up the dirt on the polishing disc in time, and avoid unnecessary damage to the paint surface.

It should be noted that although polishing can repair the paint surface, it is a consumable repair, polishing and grinding the paint surface, which will reduce the thickness of the paint surface, damage the paint to varying degrees, and frequent polishing of the paint will be less and less, so it is recommended to control the polishing frequency, and the fewer the number of polishing, the better. Choose a professional car detailing shop and polish it properly to avoid damage.

2.The polisher consists of a base, a polishing plate, a polishing cloth, a polishing hood, and a lid.

3.The motor is fixed on the base, and the taper sleeve that fixes the polishing disc is connected with the motor shaft through screws; 2.The polishing cloth is fastened to the polishing disc with a ferrule, and after the motor is turned on with the switch on the base, the sample can be polished on the rotating polishing disc by applying pressure by hand; 3.

The polishing slurry added during the polishing process can flow through a drain pipe in a plastic plate fixed to the base into a square plate placed next to the polisher.

4.The polishing cover can prevent dust and other debris from falling on the polishing cloth when the machine is not in use, which will affect the use effect;

The correct way to use car polishing is: 1. Dip an appropriate amount of car wax with a waxing sponge, evenly apply wax in a small circle rotation, the size of the circle is subject to the paint surface without omission in the circle, and each circle covers the front and rear of the circle 1 3, and the circle trajectory is along the straight line direction of the front and rear of the body;

2. Trillion years of the whole car waxing sequence: the paint surface is divided into several parts, according to the right front hood - left front hood - right front fender - right front door - right rear door - right rear fender - trunk lid in the order of grinding the right half of the body, in reverse order of grinding the left half of the body. until all lacquer surfaces are waxed without omission;

3. Evenly coat a thin layer of car wax on all paint surfaces, and the paint surface is obviously covered with a layer of car wax, and the front and rear plastic bumpers of the painted front and rear are also coated with wax;

4. 5-10 minutes after waxing, the wax surface begins to turn white, wipe it with the back of your hand, there is powder on the back of your hand, and the painted surface is satisfactory and bright, indicating that the wax has dried. Throw wax with a soft and dry towel until there is no residual wax on the entire surface;

5. After waxing, thoroughly clean the glass, bumpers, trims, tires, steel rims, etc., in the same order as applying wax. Wipe off the wax with a cotton towel and rub the paint surface with synthetic deerskin until the reflection of the paint is clearly visible.

6. The cleaning sequence is the same as that of wax, and the wax remaining in the cracks on the surface of the car is cleaned to keep the car thoroughly clean.

Millions of car purchase subsidies.

The selection of abrasives, abrasive materials are very important, to judge the characteristics of abrasives, water-based, oil-based, neutral abrasives; The choice of materials, different polishing discs, throwing different cars, using different processes; Master the rotational speed, pressure, and moving speed of the polishing machine.

First of all, it is necessary to make a judgment on the paint surface, and make a judgment on the thickness and hardness of German, American and Japanese car paints. German, European and American car paint is hard, and the thickness of the varnish layer is 60um, while the thickness of the varnish layer of the usual domestic and Japanese car paint is only 45um. The cutting force of the water-based abrasive is on the low side, but it is just right with the wool disc to completely remove scratches without concealment.

Oil-based abrasive, grinding using sponge disc polishing, the temperature rises quickly, and the masking function is stronger. Neutral abrasives are oily and oily, and wax collection is not easy to clean.

Method steps for car polishing:1Wash the entire paint surface of the car.

Use special car cleaning foam to clean the whole vehicle until the surface is clean. 2.Use coarse wax or fine wax and polish it with the help of a polisher to remove imperfections in the paint surface and reveal a new paint.

3.After the polishing is completed, all the wax on the paint is washed, and the polishing effect comes out and feels very translucent and smooth. 4.

After washing the car, wait for the body moisture to dry, carefully finish the whole body of the car with car wax, and wait for the wax to be fully absorbed after more than ten minutes, and then wipe the body carefully again, that is, complete the entire construction procedure.

Precautions for automobile polishing: for different polishing positions, you should pay attention to the strength, and do not grind the paint through; Use a large towel to cover the front windshield, the wax will stick to the wiper when polishing and it will be difficult to clean; When polishing, you should pay attention to the angle and self-protection techniques, so as not to let the residual wax fly to the face, especially the eyes.
