How to make your own hands grinder: dimensional drawings

Grinder translated to English means "crusher". The meaning of the term is clear and simple, if you look at it in the context of translation of some English words: «meat grinder» - this meat grinder, «Rock grinder» - stone crusher, «wood grinder» - branches crusher in chips. In the construction industry called grinder grinding equipment belt type which is used for finish processing of wood productsPlastics and metal. The only difference is in the choice of tapes: the more rigid it is, the more durable material able to grind. In this article, we look at how their own hands to make a grinder on ready drawings with dimensions, consider options for flexible assembly hand-held machines for surface treatment with difficult terrain, as well as the types of stationary designs for installation on grinders base. In the presented embodiments photo grinders for processing different materials.

What is a grinder, and for what it is

Grinder, in fact, - a grinding machine. In contrast to the usual sandpaper, even with the electric drive is different, first of all, for its versatility. On it, you can record rust Oldest parts clean the woodwork with peeling paint (E.g., the stool legs), to remove sharp edges, burrs from any workpieces, and the effects plasma cutting, Cleaned old welds. Sharpening angle in this car simply to replace, simply install a pressure roller to the desired position. Grinder - irreplaceable thing, if you want to grind parts with complex shapes, to align defects in products of different depths.

Price finished the grinding machine, to put it mildly, far from democratic. To buy the easiest belt grinder, you need to lay out a minimum of 20 000 rubles. More serious examples of expensive several times, for semi-professional tape machine manufacturers are asked to 150,000 or even 170,000 rubles. In this case, a reasonable solution would be to build a home-made products.

Schematic diagram grinder structure and the principle of its operation

To assemble a belt grinder with his own hands, it is necessary at least in general terms, to represent its structure. In fact there is nothing complicated. This conventional drive apparatus with several rollers and the sanding belt. It can be made both from metal and from plywoodOr even plastic. The figure depicts a drawing with dimensions grinder.

1. Base.
2. Rack.
3. The motor AIR 80A2.
4. Pulley.
5. Swivel head tension roller.
6. tension spring.
7. Direct roller.
8. Tension roller.
9. Metal table.
10. The sanding belt.

Usually in the design of the grinding machine includes a table with clamping elements, which is often installed on a workbench or a stationary frame. It can be rotated along its axis, and in some models - perpendicular. The frame is placed or treadle device, or the drive motor, which is fixed directly to Grinder. Most often, the course is rubbish with "live" engine: the old drill, Bulgarian, on the network many examples where the grinder is collected his own hands with motor from a washing machine.

Interesting fact! The longer the sanding belt, the more powerful engine for the machine will have to look for.

The principle of operation is simple grinder. With the motor driven by a group of rollers, one of which is driven, and the rest - the slave. By the draft starts moving sanding belt. The design allows you to adjust the location of the driven rollers, which facilitates work on polishing various surfaces.

Over time, the belt can be stretched, so that the tension was accurate, provided different tension system: it may be a spring, a special clip or the most ordinary furniture bolt.

"If you do not like to wear safety glasses while working on the machine, you can make a special hinged glass acrylic. For example, we can see the installed safety glass industrial machines, where the operating element is a round sanding stone. "

Before you decide on the size of the belt and the roll width, think for yourself - what do you plan to handle the surface, their size and the amount of work.

The novice master is not superfluous to know that grinding belts differ in length, width and degree of hardness (graininess). Most often in this type of machine, the following dimensions of ribbons 610, 915, 1230, 1600, 1830 mm - of length, width only two options -50 and 100 mm, however, experienced craftsman can cut the tape of any width.

Important rules for selecting a tape grinder:

1. The tape must necessarily be flexible, fabric-based, otherwise it can not withstand the load and will hurt you on the paunch and arms.
2. Soaking limiting angular velocity - of at least 1500 rev / min.
3. Possess a high abrasion resistance.
4. Ultimate tensile tension at break - at least 15%.
5. Resistance to heat after prolonged use.

Grinder with his own hands at home - text and video instructions

Buy ready-grinder, particularly for domestic use, can not afford one. Therefore, without further ado, we offer photo and video instructions, how to make a simple grinder with his hands improvised.

From what we can drive for grinder

In this section we give step by step instructions to build homemade grinders hands.

Homemade grinder with a motor on the washing machine

Illustration	Description of the action
	It needs to work a normal induction motor from the old washing machine.
	Welded to the motor two steel plates on them - washer. Mounts will help us to firmly and securely install the motor on the machine frame.
	For operation also need abrasive belt, in our case - 610 × 45 mm (width cut under our rollers).
	Ears, bolt and clip required us to create a regulatory framework to control the position of the rollers during operation.
	We begin welding roller attachment mechanism.
	By welds sheet metal frame with a slot for the motor.
	On the other side of the structure to fasten metal corner rigid fixation of the engine.
	Set pulley in the form of the bowl on the motor shaft, it is keyed on the fixed phase.
	Pre-machined rollers with spacers, they set the bearings.
	Based on the tape tension, try on the installation location of the retaining mechanism for the follower roller, note space fasteners, alignment structure so that the tape has been sufficiently tightened.
	Drilled hole for fastening bolts on which the entire structure will be kept in the future.
	Bolt will in future carry out a more accurate adjustment of belt tension.
	Our design allows the bolt to function as a pendulum, and thus easy to control the tension of the sanding belt.
	And with the help of the handle with a bolt, we can adjust the position of the rollers relative to each other, moreover it can be done even while the machine is running.
	To adjust the tension of the tape used furniture gas overpressure.

Grinder of this type is easy to help sharpen dull drills or small elements.

Grinder for drills

Grinder for drill - a special attachment that can be done in several stages. Options for what it can be hundreds. We have chosen a non-standard model.

Illustration	Description of the action
	To work with the required shaft gears, bearings and the sheet metal.
	Cut two plates the size of 110 × 250 mm.
	Necessary holes drilled on each of the plates.
	In this part of the bearings will be made to adjust.
	Next, we take "hairpin" and cut to 120 mm.
	Set the self-made videos on the studs, bolted.
	We stretch belt and fasten the other side.
	We make a basis for fixing the grinder.
	Grinder is mounted on a frame, and drill fix the clamp.
	Do not forget to carve a place for easy fixation of the knife during sharpening.

These grinders can help erode the blades or any flat parts.

Grinder of Bulgarians own hands: Drawings

This is one of the easiest grinders, which can be made with your own hands. The design of such a mechanism is designed primarily for cleaning welds. However, if it is rigidly secured to the table, it can be successfully used as a grinding machine for cutting tools or knives, axes, etc.

Grinder of sanders with their hands

Illustration	Description of the action
	All that is required of you - to find a grinding machine, for example, that such.
	Next, gather the design - the foundation for a sustainable and secure mounting of the machine. Reducing reinforcing structures corners. The main thing - do not forget to provide a hole for the wire.
	The top is very basic, but here you can attach a canopy of dust in the future.
	And our grinder turned into a grinder for knife sharpener and metal structures.

How to glue the ribbon to his hand grinder

For the work we need: super glue PVA, pinch Strubtsov.

Illustration	Description of the action
	Cut the emery tape width, which is necessary, we will here a skein.
	Remove the abrasive layer at a distance of 2-3 cm from the edges of tape, glue patch from a piece of cloth, it presses Strubtsov, waiting for the glue to solidify, and severing our "patch". Here's a "tail" we should get.
	Next, take the sandpaper at grain, usually take into account the difference to one point, if the main grain belt - 3, then sandpaper take the number 2. And glued flush to abrasion.
	Here we have turned plate. Now that you know how to make a tear-resistant tape for grinder hands. Guarantee work flawlessly - until complete erasure of the abrasive layer.

Important! Choosing a tape grinder, it is important to calculate the diameter of the pulley on the engine revolutions and the desired tape speed. Too slow running the tape will tear the material being processed, and too fast - she erased, not really anything processed.

How to make videos for the grinder with his own hands

Grooving rollers for grinder - one of the most labor-intensive stages of the work. Usually grinder make four rollers of different sizes - from 70 to 150 mm. Commonly used metal (steel suitable, preferably titanium or duralumin), however, some masters prefer tree. The width of the rollers depends on the size of a ground belt.

When you create a drawing for making videos, remember that videos must be barrel-shaped, it's making sure that the tape. Drawing - a mandatory condition for work, because, most likely, you will have to refer to the turner. If you want your device to work efficiently, you should not save on this, moreover, should be chosen bearing grade 6 and above.

Pulley for grinder with his own hands

Pulley for grinder after the actual engine - one of the most expensive elements of the grinding machine. Finished part is not less than 2000 rubles. However, the master for his homemade use wooden prefabricated structures made of wood. Let us briefly examine the sequence of the recess of the pulley and rollers made of thick plywood CNC machined.

Illustration	Description of the action
	A special algorithm machine begins to consistently cut product layers exactly on the set sizes.
	These are blank, we have turned out. Dorezaem remaining ring size.
	From these rings collect pulley and barrels, fastening parts glue.
	With the help of a grinder moonlighting slants to the tape tightly held.
	We treat the resulting structure by impregnation.
