All about brake disc grooving machines

Brake discs are an important part of any vehicle. It is these components that directly affect the safety and reliability of the ride. Not always when they wear out, people acquire new ones, but use the opportunity to grind old ones. For this there is a certain type of machine.

Brake discs tend to wear down over time, which reduces their efficiency while driving... Such machines make it possible to restore the original properties of parts by removing the excess steel layer, as a result of which the working function of the product is restored. This equipment is often available in many car services and service stations, where motorists can turn to in order to solve the problem with a decrease in the efficiency of drives. The versatility and variety of machines allow them to be operated with a wide variety of details, among which we can single out products for both cars and trucks, because the principle of operation of the brakes is the same.

Most of the modern models of machine tools make it possible to perform operations of grooving discs without removing them from the machine, which saves time on the implementation of the working process. It is also worth noting that the many functions and the difference in characteristics allow the user to select the equipment in accordance with the criteria that will be most noteworthy within the scope of application. The equipment layout is the overall structure that makes up the machine.

The user can adjust the intensity of the work process by changing the speed of the spindle head. Increased mobility is achieved due to the presence of a movable frame, which makes it possible to work with the brake disc without removing it from the car... Initially (before the groove itself), it is important to determine the degree of wear of the product, whether it is possible to restore the efficiency of the part with its subsequent installation. Then, on the machine, certain parameters are set corresponding to the size and type of discs, the outer diameter is taken into account, the necessary cutter with the required characteristics is selected.

The next step is direct groove. During the implementation of this process, the employee must carefully ensure that only the necessary layer is removed, because otherwise the groove will be either insufficiently effective or excessive, due to which the brakes cannot be safely operated in the future. After the machine has completed all the main work, the final stage is to check the dimensions of the turned disc.

Before buying, it is important to consider many factors: the manufacturer of the machine, its available equipment, reviews and characteristics. It is the technical part that is one of the most important, since most buyers choose products for it. The first parameter is to select the thickness (minimum and maximum) of the processed disk. This indicator is very important in order to understand what elements can be turned on the machine. If we talk about some mobile models, then their functionality does not allow working with large disks, which reduces the versatility of the equipment in comparison with larger counterparts.

This also applies to the permissible workpiece diameter. The step of the cutting head is also important. The smaller it is, the more accurate the turning becomes. Accordingly, the result of the work of such products is more efficient, and they are suitable for performing more complex disk operations. The amount of turning performed directly depends on the power of the electric motor and its connection system to the mains. Inexpensive models are equipped with motors with average characteristics and support operation from a 220 V outlet. If we pay attention to large machines, their motors are more powerful and consume more electricity. And they need a 380 V power supply.

As a rule, such equipment is necessary only when it is planned to grind discs of various sizes in a continuous mode. If the service station is small, then the standard characteristics will be quite enough. Among other parameters, a special place is occupied by the speed of the drive shaft and the accuracy of rotation. They are important because they determine the overall quality of the equipment. Power is good, but it is not very useful if the cutter grinds the discs very roughly and the result does not meet machining standards.

Also, some users select machines wherever possible to change the height of the cutting unit for more accurate positioning of the blade. Of course, the dimensions and weight of the unit are very important, since such a technique takes up a lot of space and requires placement. It is important here to prioritize correctly as to what should be emphasized: power and bulkiness or small size and average performance.

The main classification of these machines is based on the principle of preparation for work. Thus, there are two types of equipment: with the need to remove the disc from the car and without. In the first case, the equipment is not equipped with systems of movement to the brakes. The absence of such a function makes the technique cheaper, but because of this, each groove takes longer.

You can also select machines depending on the degree of automation and versatility. It manifests itself both in the basic and in the additional equipment configuration. A clear sign of automation is the displacement of the cutter by the slide. This function can be carried out by the machine independently or exclusively with the help of the user. Additional equipment may include a variety of tools: hold-down cups, centering cones and other devices.

Among the majority of manufacturers and models in the current equipment market, there are many drum and disc boring machines that are popular. One of these is the AE&T AM-8700M. The unit is manufactured in China and due to its characteristics has become popular in the Russian Federation and the CIS countries. The thickness of the processed disc is from 6 to 40 mm, the maximum diameter is 400 mm.

The advantages of the machine are worth mentioning high accuracy of head adjustment in 0.005 mm, rotation in 0.005 mm, as well as changes in thickness for the workpiece being processed from 0.005 to 0.01 mm. Dimensions AM-8700M are 1100x530x340 mm, weight - about 70 kg. The technique allows turning discs without removing them from the machine.

Comec TR470 is a powerful machine from a popular manufacturer known for its quality and reliability of manufactured products... An automatic cutter feed system is built-in, there is a set of centering cones for mounting drums and discs of various sizes. A tray for collecting metal shavings is provided, an optional stand is available. Two handwheels allow you to quickly change the position of the machine and adjust the speed of its work. There is a cutter holder, motor power - 750 W. Power is supplied from a network with a voltage of 380 V.

Cutters feed at a speed of up to 27 mm / rev, drum diameter up to 710 mm, and its depth up to 210 mm. The maximum disc diameter is 860 mm, the rotation of the machine head in three positions - 70, 100 and 145 rpm, the movable table has a stroke of 150 mm. Dimensions TR470 - 600x800x1000 mm, weight - 205 kg.

The use of the machine takes place purely in the stages that were described earlier. It should be noted that the entire operation of the product must be carried out in accordance with the safety standards declared by the manufacturer.... This applies both to the conditions for placing and setting up the machine, and to the attentiveness of the user during the work process. Do not forget that you only need to grind discs to a certain extent in order to get the desired result. Before every start-up and operation of the machine, check its power supply system and the reliability of all fastenings, especially the turning tool.
