Circular slide machine. Appointment and device of round sloping machines

There are quite a lot of different metal processing equipment that can be used for surface grinding. Grinding is a mechanical processing that allows you to change the surface roughness of the surface and the features of the part of the part. Some models can be called universal, their appointment is grinding parts of various shapes. The greatest distribution was obtained circular fluffing machines, the purpose of which is to grind the billets of the cylindrical shape.

Purpose

The circular flux machines are used to process the outdoor cylindrical surface, the billet fastening is carried out in centers and a carton. In this case, a longitudinal and transverse feed can be carried out to achieve the desired result. The universal version of the performance is suitable for various sizes, some species can be used in industry to obtain particularly large parts.

During the operation of a universal machine with centers, the direction of rotation of the workpiece is opposite to the direction of rotation of the abrasive material. Similar models can be used in various types of production.

It is worth noting that the circular fluffy machine is used at the final stage of production. Encetric and other types of models carry out grinding after turning, milling, drilling, and so on.

Main settings

When choosing equipment, its type should be taken into account that determines many important grinding parameters. The main parameters can be attributed to:

1. Possible dimensions of the center installed. In the case of a powerful model, the table size can be called an important indicator.
2. The diameter of the circle and the speed of its rotation. Universal versions can be used to obtain parts of various shapes, they may be conical.

In the passport indicates all important information. The drawing and passport allow you to determine what specifications have a design. Drawings are drawn up with GOST, as is the passport.

The above information should be taken into account when choosing a model, a circuit of a circuit sloping machine reflects all its features. Therefore, to determine important points, drawings and a passport, compiled according to GOST, should be considered.

Classification

Certain points specified in the drawing and passport determine the following classification of grinding equipment:

1. Universal have a rotary desktop, it is possible to turn the billet and the grinding wheel itself. The universal version of the performance is supplied with an additional grandmother.
2. Simple allow us to process only certain blanks.

Numeric software management allows you to increase the degree of automation of work several times. At the same time, we highlight the following points:

1. High grinding accuracy. The mechanism that is used for fastening and supplying a circle, with an automatic feed allows you to get dimensions that may have a deviation of only several hundred millimeters.
2. Significantly increases productivity. Most of the stages of the technological process are performed automatically, which means they do not require the intervention of the operator.
3. The likelihood of marriage is reduced. If you reduce how many steps will be performed by a person, you can reduce the likelihood of problems.
4. The costs are reduced due to the fact that one operator can serve several jobs.

The CNC circular sloping machine is quite rare, as it is used in rare cases in large-scale and mass production. The cost due to the inclusion in the design of the numerical software management system is significantly increased, so it is necessary to use it only with large production.

CNC metal circular stained machines from the Swiss Studer company at Galika AG warehouse in Moscow - in stock and under the order. Studer is a hardware and software, system integration and service of higher Swiss quality. The company has 100 years of experience in the development and production of grinding equipment.

Studer S20 and Studer S30 machine tools are designed for grinding parts in single and small-scale production. They are suitable for use in any industry, in which accurate small details are manufactured. Management is very simple, and the caller is possible for a short time.

Universal round-winged machines

Universal CNC circular grinding machines are designed for grinding details of small, medium, large size in flat and serial production.

Production circular fluffs

The Studer S11 model is designed for those customers who are aimed at serial release of small shafts and sleeves, outdoor treatment with high speed and high accuracy.
Studer S22 is a production platform. Its main purpose is the mass production of the details of the medium-sized customer. The combined processing Studer S242 perfectly combines the technology of round grinding and sharpening.

Circular slide machines Schaudt

Schaudt is a German manufacturer of high-class grinding machines. The company establishes global standards in technology, accuracy and quality center grinding round and non-circular details. The Schaudt FlexGrind M model is designed for grinding long and heavy parts.

Circular slide machines belong to the class of metalworking equipment. With their help, they perform accurate grinding of metal blanks on the outer surface. Constructively, the machines of this type differ significantly from similar equipment.

Design features of equipment

The principle of operation of round sloping machines is based on the fit of the workpiece with the help of the guide circle or mounting in cents. The processing is performed by touching the working rotating abrasive with the surface of the part. Thus, a uniform removal of material is carried out with the formation of the optimal irhanction indicator.

The classic layout of the machine is a combination of turning and grinding. To fix the workpiece in the design there is a special unit. This can be a system of cartridges holding the item in a horizontal position. An alternative option is the use of an additional circle, which presses the blank to the abrasive.

The circular slide machine has the following advantages of use:

• ability to handle parts with different dimensions. It is important to take into account their mass;
• accurate setting of parameters. To ensure high quality grinding, it is recommended to purchase models with automatic feed;
• selection of the machine model for specific production tasks. This will ensure maximum performance and reduce the cost of the product.

However, to select the optimal model of the machine, it is necessary to familiarize themselves in detail with their varieties and operational qualities. It all depends on the configuration of the processed parts, as well as the requirements for the quality of grinding.

An important point is the configuration of the abrasive disk - its graininess, the area of \u200b\u200bthe working surface. These characteristics directly affect the quality of grinding steel blanks.

Types of round-slopheal machines

In practice, circular or oval billets are subjected to circular or oval sections. Grinding of complex parts on this equipment is impossible due to the specifics of its design. It must be considered when choosing a machine model.

The most common models of circular slide machines is the equipment in which the parts are installed in the centers. Fixing the workpiece is performed between the front and rear grandmother. To improve the quality of grinding, the body rotates. When it is in contact with the abrasive disk, the excesses of the material in the form of metal dust shavings take place.

In addition to this technique, the so-called non-centered circular grinding machines are recruited recently. In them, the workpiece is placed on a working faucet and on the one hand is held with auxiliary circle, and the other is grinding the main abrasive. Thus, you can perform high-quality thin treatment of thin-walled cylinders or cones. The degree of pressed is regulated using the automation system.

Additionally, it is necessary to take into account the features that the circular chlorinous machine possesses:

• the presence of the turntable. With it, you can displacing the workpiece relative to the abrasive disk in the horizontal and vertical plane;
• device of the feed mechanism. It can be an automated complex or its mechanical analog. In the latter case, the machines of this type are used for rough grinding;
• the ability to fix the workpiece in the centers, the cartridge. This parameter applies only to the equipment of the center type.

Currently, a large number of models of round sloping machines are produced. Therefore, in addition to the choice of constructive parameters, technical and operational quality equipment must be taken into account.

For grinding over the entire surface of the workpiece, the circular slide machine must have a mechanism of displacement of the abrasive circle. In this case, the longitudinal supply of abrasive and transverse details are taken into account.

List of basic technical characteristics

As an example, it is possible to consider the operation of the standard model of the 3m152 circular grinding machine. In it, the processed item is installed in the centers. A similar design has a large part of such equipment.

The best technical characteristics of the machine are conditionally divided by its nodes. Structurally, it consists of a block of fixing the workpiece, the processing center (grinding grandmother) and control systems. The average mass of this machine is about 8 tons. At the same time, it has large dimensions, which makes special conditions for installation and operation.

Basic technical parameters:

• the maximum permissible dimensions and the mass of the workpiece treated;
• grinding diameters - minimal and maximum;
• the distance from the axis of the spindle of the front grandmother to the surface of the desktop.

Desktop Characteristics:

• displacement of the desktop - maximum length;
• parameters of manual acceleration and slow motion;
• angles of rotation clockwise and counterclockwise;
• displacement characteristics using a hydraulic system. This is necessary for processing massive parts.

The fixation of the details takes place between the front and the back of grandmas. They must be analyzed by the following parameters:

• rotation frequency;
• for the back grandma - the magnitude of the bias of the pinley.

In addition, the total power consumption of the equipment is taken into account, the ability to install auxiliary structures and the cooling system parameters. The presence of the latter is a mandatory requirement for industrial models of round sloping machines.

To maintain the machine in working condition, it is necessary to periodically carry out preventive and repair work. It is especially important to apply lubricant to moving parts of the equipment.

Round grinding methods

To perform external grinding, you can use several techniques. The choice depends on the desired result, as well as the actual characteristics of the equipment.

The most common is the method of longitudinal processing. The billet is attached in the centers. Using the drive of the front grandmother, it is attached to the rotation. At the same time, the feed mechanism provides a longitudinal displacement of the part relative to the abrasive circle.

In addition to this method, modern round-fluffing machines can perform the following types of processing:

• deep. It is used for grinding short parts. In one pass, up to 0.4 mm of material can be removed. The main processing process is performed by the conical part of the circle;
• curling. With its help, it is possible to effectively make a vindrious or finishing grinding. For this, there are wide abrasive circles. In the process of processing, the part does not shift relative to the instrument;
• ledge. This is a combined view that combines deep and mortise grinding. The optimal option for removing the excess material from the blanks of complex shape.

Most of the models of circular slide machines can perform all the above processing types. It is important only to correctly select the characteristics of the equipment to achieve the desired accuracy.

As an example, you can see the video in which the operation of the CNC circular chlorinous machine is shown:

Grinding (grinding) is a method of processing the part to the sizes set. This uses abrasive materials applied to grinding circles. Round-slip portable metal machines have multiple version options, both manually control method and method with CNC systems (3ow10A, series Studer machine tools, etc.).

Circular slide machines are widespread in manufacturing plants that are engaged in producing products by large, medium, small series and even single instances. The universal circular fluffy machine has an appointment for grinding cylindrical and conical parts both inside and outside.

As a rule, the part falls on such a final processing machine, which provides high accuracy of control over the parameters and purity of the surface.

1 modifications

2.9 How it works round slophing machine 3K12? (video)

Now many important enterprises require the manufacture of accurate parts with a rather smooth surface. You can perform such work using different abrasive techniques, including round-fluffy equipment. Round-slip machines can be attributed to the class of metalworking tools. With their help make accurate grinding of metal blanks on the outer part. Structural tools of this type are very different from similar equipment.

Purpose of machine tools

The main purpose of such equipment is this processing of the external parts of the partwhich has different forms. For example, cylindrical, straight, or conical shape. Due to the fact that grinding and diamond mugs are used in this equipment, a rather high accuracy of size and geometry is ensured, as well as light roughness of the processed parts. Most often, circular slides apply after the part passed the first (thermal or mechanical) processing. Experts share circular fluffs for a couple of species, there are ordinary options and there are universal.

• A simple circular fluffy unit produces the processing of parts that have small tales, no more than six degrees.
• Universal units can handle parts with a huge corner of the cone, this is possible due to the design features of these machines. The fact is that they can be rotated the anterior and grinding grandmothers. The newest models of circular slide aggregates have such characteristics that help them work with the billets that have a huge diameter and size. They are fully automatic and semi-automatic.

Characteristics

Round slophing machine 3m151

This unit works in our country for a very long time. It helps at the highest level processing cylindrical, intermittent cylindrical parts, as well as the surface of different cones.
