Grinder with his own hands: dimensional drawings and assembly algorithm

Grinder called special grinding apparatus, which has an electric drive and a tape coated with an abrasive. Such a device is used for finishing of metal, wood and plastic surfaces. The main thing that you should pay attention to collecting grinder with his own hands: dimensional drawings, work steps, the choice of suitable materials.

Belt sander with their hands: operating principle

A distinctive feature of this device is that it has a simple construction, which can be repeated any person in the home. The structure of such a grinding unit includes an electric motor, rollers and directly working tool - the coated abrasive belt. The strip may have a different granularity. This rate is selected in accordance with the purpose of the tool.

When assembling the grinder with his own hands at home should prepare and examine how it works. When the unit starts the engine. It has a shaft, which is joined to the main (leading) roller. The roller starts to rotate about its axis, by acting on the abrasive belt via the secondary (driven) rollers.

Grinding is done quite simply when the circuit breaker. To do this, you need to make the workpiece against a moving abrasive belt. During operation, it is necessary to focus on the position of the operating band.

Made with their own hands grinder will allow for machining of various materials. Such a unit has the ability to eliminate defects on the surface of metal, wood, and glass. Using grinders, compactors are often adjusted, which enables to perform processing defects of different depths.

It should be remember that long-term use sanding strip is worn, causing it to stretch. In these units, this problem can be solved very simply. One of the rollers of the device contains a special mechanism to pull the tape. In most cases, such a device is installed on the roller disposed between the main roller and the secondary device.

It is recommended to take into account all the nuances of the design of the factory units. This will allow to make the most efficient grinding machine table. The standard device of this type equipment includes a support table. In addition to the main purpose, this surface also performs an auxiliary function: used for fixing the workpiece.

The factory devices such table can be rotated relative to one axis. The rotation angle is generally equal to 90 °. This enables two planes grinding the workpiece (perpendicular) without changing the position of the part fixed on the rotary surface. When assembling a simple grinder with his own hands, you can make a static table. This greatly simplifies the assembly, but the finished unit will have less functionality.

There are other, no less important details that go into the design of these machines. Consider what other structural elements must necessarily be of any grinder used for grinding of workpieces of different materials:

• rollers;
• base;

• tape;
• tensioning mechanism;
• Protective wall.

All these details are quite easy to make your own hands. Belt grinding machine during operation can produce dust or sparks. This depends on the material of the workpiece being processed on such machine. Because of this, experienced craftsmen strongly recommend the use of special glasses. In addition, it is recommended to organize a protective wall for the manufacture of acrylic glass which is used.

Portable units are completed with body made of steel. Reception grinder must have openings that are necessary for fixing the apparatus on the wooden surface (through bolts). When choosing a tape worth considering that its length depends on the capacity of the machine (and vice versa). The higher the value, the respectively to be a more powerful drive.

How to make your own hands grinder: Assembly rules

Before starting the self-construction of the grinding machine of this type is necessary to carefully consider the sequence of actions, as well as to take into account some of the rules. The first and most important step is to prepare the assembly grinder. Consider what actions includes the item.

First, we should make the appropriate drawing. It should be remembered that the scheme must comply with the specific operating conditions. The drawing can be formed independently. The second option - to download the finished circuit from the Internet. At specialized sites and forums you can find many versions of such devices, the design of which is most suitable for home assembly.

The detailed drawings, the better. The circuit should contain a detailed description of all the individual design elements with their size. Drawing with dimensions - a very important document, which will depend on the performance and specifications of the machine of the future. Therefore it is necessary to approach to its development very seriously.

Independently can perform different versions of grinding grinders. In addition to stationary devices, there are more simple types (for example, the grinder of grinders with their hands). Drawing and video to assemble such a device can also be found on the World Wide Web easily.

The next thing that is worth considering - preparation of all necessary parts and tools for assembly unit. To construct the grinder at home need the following tools:

• jigsaws;

• drill;
• Bulgarian.

Note! In the selection of tools is necessary to consider that the grinder design involves the use of metal parts, as well as their processing.

Many details of the grinding equipment is difficult to manufacture a novice. Therefore it is recommended to study in detail the various components and their features. It does not interfere too familiar with the drawings and videos. Grinder with his own hands made much easier if you have the opportunity to consult with a qualified technician who can provide valuable advice on the matter.

Some components can not be created with their own hands without the use of a turning equipment. Such work necessarily do on their own. For complex parts, you can use the services of a professional turner.

In the manufacture of grinder with his own hands, it is desirable to take into account another important point. It is considered the most effective device that can be used to process not only horizontal but also vertical surfaces. Experts recommend to choose a drawing allows grind workpiece at different angles.

Grinder with his own hands: dimensional drawings structural elements

The development of an appropriate scheme is an important preparatory step. Plans are available from a qualified professional. In this case, it will be as accurate as possible and allow the manufacture of equipment that will last for years.

How to make a grinder with his own hands? Drawings, video, and photos grinders various stages of assembly - all this makes it possible to perform the high-quality unit.

Second Embodiment - load circuit of the World Wide Web. In this case you should be aware that some blueprints located on the Internet, are not effective. Therefore, before you download a particular scheme, it is recommended to read reviews of real people who have used it to build the band-grinding equipment.

It is also recommended to compare the scheme drawn up independently, with other drawings with dimensions grinder with his hands. Videos that have relevant topics, allow faster to understand all the nuances of manufacturing such a unit. On the Internet, their huge set.

The scheme must be accurate and contain outline of the construction of structural elements. It is mandatory to specify the dimensions of the individual parts. And, finally, the finished scheme can be put on the profile forum and ask what it contains inaccuracies. It is possible that in this case will be able to get valuable advice on its improvement.

Homemade machine grinder with his own hands: Selection of a suitable drive

Before proceeding with the assembly of such a grinding machine, it is necessary to prepare a suitable motor. Most often used for this drive, whose power is at least 1 kW. There are several factors that should be guided in choosing the motor. Let us consider them in more detail.

The first thing to understand that for home use suitable devices operating from a standard network. The voltage in such a network has traditionally is 220 V. A higher voltage is required to use professional equipment, which occurs in small businesses, but not for a device made with their own hands. Grinder grinder should be created in accordance with the pre-prepared drawing.

Another important point - the number of revolutions of the drive. From this parameter depends on machining accuracy. There can be traced a certain regularity. The higher the power of the engine, the greater the number of turns it will be able to produce.

A most suitable embodiment of the actuator includes a special design of the blade. Their function is to neutralize the overheating that occurs during engine operation. Such a device is simple to make your own in a home workshop.

Most often for the assembly of such a simple grinding equipment used motor from a washing machine. Grinder with their hands of this type meets all the performance requirements and is used for the treatment of small workpieces made of metal, wood and plastic.

Features grinder manufacturing of washing machines with their own hands

Engine power is selected depending on the dimensions of other structural elements. In particular this applies to the size of the main (leading) of the pulley. If the size of the standard cell is 150 mm, then the necessary motor having a capacity which allows to issue to 3000 rev / min.

Buy ready-made engine, of course, possible, but it will take extra finance. The best option for assembly at home - use unnecessary engine from the washing machine. Grinder, which is based on such a device is, of course, is not able to compete with the factory, but it is well suited for simple everyday operation.

Engine, disassembled from the old-type automatic washing machines, has a low power (below 300 watts). It is characterized by a good reliable and unpretentious in operation. The popularity of using just such a drive due to its wide distribution.

The drive from the washing machine in the mandatory pre-entered in the drawing. Grinder with his own hands at home in need of the presence of the motor to the output shaft. In this case, the shaft has a threaded connection, which design allows to perform docking with the pulley easily.

Note!To assemble the engines grinding machines are suitable not only with the old automatic machines, but also a new generation of drives. In the second type of device it is necessary to remember that they need a device that will adjust the number of revolutions. This is due to the fact that the maximum rotational speed of actuators can be up to 18 thousand. rev / min.

a new generation of drives have one significant disadvantage. With the active use of grinding equipment is very rapid wear of engine brushes.

When designing your own hands from the grinder motor from the washing machine should also bear in mind that such a drive is best suited for a small unit. Therefore it is necessary in advance to select the optimum dimensions of the leading and secondary rollers.

Construction of rollers for the grinding machine of this type - serious step that requires care and precision. One of the most important elements of the grinder is the main rink. It is necessary to remember that its size should be larger than the size of the remaining rollers.

Leading rink has similar geometric figures is not accidental. These dimensions make it possible to avoid unwanted spurt that occurs during starting torque. It is also important to understand that for the manufacture of a structural member in any case you can not use materials that are heavy. These materials include:

• steel;
• cast iron.

Before the creation of the rollers, it is necessary to prepare the corresponding dimensional drawings. Belt grinder with their hands should be easy and convenient small size rollers. As a rule, it is enough to carry out a simple job of polishing.

To reduce the weight of the leading roller can be constructed steel part with a cavity. There are special directories that allow you to carry out the calculations required for the procedure.

The second option, which is the most commonly used home worker - the use of aluminum. This material has a low weight and is ideal for this purpose. It contains impurities of copper and magnesium, which provide increased strength of the alloy. To assemble the grinder is accepted to use the brand duralumin D16 and higher.

How to make videos for the grinder with his own hands? Experts recommend that you perform on a pulley groove on the end. Its dimensions are selected based on the size of the abrasive belt, which will be used in the machine. This measure is aimed at preventing the gathering belt during operation. It is desirable to do the same with the remaining manipulation and rollers.

Very great importance is the degree of roughness of the rolls. The surface of the rollers may have different levels of roughness. When assembling the grinder rollers recommended in which the active component is in the range of from 1.25 to 2.5. A table containing information on the degree of roughness of parts, can be easily found on the Internet. Pulley for hand grinder mounted on its equipment through the bearing assemblies.

In this case, the closed-end bearings, which have a static outer ring and are self-centering category. Installing these components eliminates the possibility of any ingress of abrasive or other foreign particles on the roller shaft.

When selecting bearings need to be sure to take into account their carrying options. These parameters define what kind of load can withstand detail. The higher the number of revolutions of the machine, the more reliable the bearings should be. During operation, it is not recommended to deviate from the drawings with dimensions. Belt grinder constructed in accordance with the scheme will have a higher efficiency and a long useful life.

How to fix the clip on the device? The easiest way at home for fixing the roller use the standard pin. Another embodiment -Application fastening bead (at one end of the axis).

The characteristics which must be met for the grinding belt assembly

Selection of abrasive strip - an important stage in the assembly of mini-grinder with his hands. The first thing to decide on the length of the tape and its width. On band geometrical parameters are influenced by two major factors:

• grinder sizes;
• the appointment of the unit.

Endless abrasive band is also divided into types of grain. sanding strips can be of different length (from 610 to 1830 mm). Such tapes have a width of 50 mm or 100 mm. The first option is most common in the units, collected his own hands at home.

High-quality abrasive band is mandatory should be an elastic base fabric. When selecting a suitable tool also necessary to pay attention to a number of turns can withstand strip. It is recommended to purchase products that are capable of operating at 1500 rev / min. This option is best suited for the manufacture of the belt grinder with his hands. Plans drawn up earlier, and shall include the dimensions of the abrasive band and its other characteristics.

Good tape must have high abrasion resistance. From this figure depends on the resistance to wear and tear tape. For home-made devices it is recommended to use a tape whose length is not more than 123 cm. The abrasive strip must not only be resistant to wear, but also have good resistance to high temperatures, formed during the friction of the workpiece during operation.

It should be noted that the tape short length are much more susceptible to wear than the product more length. Experts advise to pay attention to the pictures of the finished products. Photo machines allow us to give an answer to the question of how to make the grinder by hand. The drawing device can be considerably simplified if used in its assembly of ready-made items purchased separately.

Finally, special attention should be paid to the place of bonding an abrasive belt. The junction of the two ends of the strip should be as neat, without any defects or protrusions.

How to glue the tape grinding machine yourself

Belt grinding machines comprise a spring, which performs a very important function: tightens sagging as a result of wear and tear tape. Changing the tape is made several times, even when handling small blanks. It should be remembered.

During assembly of plywood or metal grinder their hands abrasive strip can be made independently. Gluing a ribbon - a complex event, which does not tolerate mistakes. On the Internet, there are many tips on how to properly perform a gluing tape, but many of them are wrong.

Gluing process is as follows. First, you need to choose the emery cloth material. Then should prepare both ends of the abrasive strip. This is done by trimming them. The seam on the strip is carried out exclusively by the "butt". Experts recommend necessarily enhance the glued tape from the inner side by a dense fabric strip, which is fixed with a special adhesive.

Note! For gluing tape in any case can not be used glue "Moment".

In order to connect the ends of the abrasive band is required to purchase a special adhesive compound. Best Mode - applying an elastic adhesive. Saving is not worth it, because cheap funds are generally not of good quality.

Before starting the gluing is necessary to prepare the strip for emery belt. Grinder with their hands (from scrap materials) needs a robust abrasive band, which is difficult to perform at home. The process is performed using an adhesive stick, which is installed on Thermo. Initially produced heated composition. You can use the usual phenomenon, which is in every house.

Homemade grinder: dimensional drawings of the turntable and tips for assembling

In the home environment can be constructed as a simple variant of the machine, and a functional device. In order to expand the operational unit ownership and provide ease of use, made reference rotary table type. This surface is set by the volume of the pulley.

The advantages of using the turntable obvious. Primarily this will fix the item in a certain position, which will facilitate its handling. When assembling the rotary grinder with their hands should be possible to change the direction of the abrasive strip. Emery must necessarily move in the direction in which the working surface has been deployed.

Table must be equipped with a movable latching element - bracket. In this part, the rotation function is to be implemented with respect to a horizontal axis lying at fixed angles.

Most often, simple machines, produced in the home, using a table of duralumin. It is also possible from the tree. Drawing machines are prepared in accordance with its design features. The thickness of the surface which is used for the manufacture of duralumin, should be at least 15 mm. This is very important, since a thinner table can not sustain the workload.

The function of the pressing plane in this case carries out the frame unit. This requires the preparation of the chassis. Simply perform a polishing surface of the frame - one that is at the stage.

Grinder with his own hands at home of drills: features of the assembly

Such a grinding apparatus can perform a more simple way. Of course, the assembly of the stationary unit, which is intended for mounting on a table, is the best option, allows to perform grinding of various parts on a continuous basis. There are other, less sophisticated options for the establishment of a grinding device with your hands.

If desired, can be made with his own hands from the grinder or sander from the drill. The drill is an electric tool, so you need to follow safety rules when working with such a device.

The need for processing metal and wood workpieces occurs in the home quite often. Acquire a factory for assembly of small volumes of work - not the best solution. The easiest way to make a simple grinder, using a drill.

Most often, for the assembly of a grinding cup used available materials such as wood, plastic, plywood. Before you begin, it is recommended to prepare the packing scheme that would make the grinder by hand. Videos on this subject are also recommended for viewing by specialists, as they cover all the nuances associated with the assembly.

It is said that when dealing with small workpieces made of plastic and wood the milling unit shows itself almost worse than stationary equipment.

Another advantage of this solution is that in current models of drills there is a dedicated controller. Its function is to adjust the drive speed. Constructive simplicity and high efficiency are reflected in the popularity of such a decision.

Grinder with his own hands at home: video and assembly instructions of grinders

Stationary grinder for home use for its intended purpose resembles a device, made of a drill. Devices which are based on angle grinder or as it is called, Bulgarian, have their own characteristics. Bolgarok main distinguishing feature is that their drive has a high speed of rotation.

Thus, for the manufacture of the grinder grinder may require a device which controls the drive speed. Angle grinders often used as an electronic file. For this sale, there are special belt grinding attachments, namely:

• narrow;
• long.

These tips are quite popular among the masters. With they can easily handle different remote places (e.g., holes). Make a grinder of grinders with their hands is easy. To do this on their own to design abrasive nozzle, which is based on the tape the desired size. However, much easier to buy a ready tool.

The main structural difference of angle grinders other equipment, operating from the power supply, is the location of the output shaft grinders. This element is deployed at right angles to the body. As a result of this design is very user friendly and helps ensure a simple fixation of the drive roller and the abrasive cloth.

Thus, such a nozzle is easy to perform with his own hands. Drawing from the grinder grinders can be found in one of the specialized forums dedicated to the subject. A tool of this type is quite comfortable to use. An elongated nozzle body promotes grinding work of all kinds.

Making a simple grinder at home is not a difficult undertaking, if the matter is approached correctly. Of course, with your own hands can be designed and more functional equipment, but this work requires more time, material and effort. Choosing the appropriate drawing must be carried out, focusing on the individual needs.
