In which direction the angular grinder is unscrewed

How to remove a disk from a corner grinder. An angular grinding machine (then an angular grinder), in the abdomen called a corner grinder, is probably the most necessary inventory, which is in the arsenal of actually each master, regardless of its qualifications.

This is the tool intensively used in abrasive processing: cutting, grinding, stripping blanks made of stone, metal and others. It is vast in areas such as: construction, woodworking and other similar works. As well as other tools, no corner grinders are also separated by several classes.

There are subsequent: household, semi.professional and instrument of the grade class. This systematization is determined by the power resource of the tool, its performance, the presence of certain additional options, material and the quality of the assembly, etc.

Consumers for corner grinding, in addition to different types of cleaning brushes, are cutting circles and various grinding wheels. Types of equipment for corner grinders: how to make the right choice?

Corner grinder disks differ from each other in the following main features:

  • External diameter;
  • Disk thickness;
  • The material from which the disk itself is made;
  • The line of the highest speed of rotation;
  • And, of course, the area of ​​the proposed work.

For better awareness, it is necessary to consider the main types of discs for the corner grinder and give a definition of their use:

  • Cut.off circles. These are the most extensive used consumables for corner grind. Their main purpose is working with metal, stone and wood. A variety of cutting circles for corner grinders are diamond discs. This is an ultra.strength equipment for processing materials of high strength, such as reinforced concrete, tile, porcelain tile, marble.
  • Grinding and pending circles. As it becomes clear from the name, this type of disks is used to polish different materials, for example, polishing products made of stone, or to eliminate (peeling) of the upper layer, for example, eliminating a layer of rust or old paint coating.

Survatory circles for corner grinders, in turn, have their subspecies, such as:

  • Cutting circles for metal work;
  • Abrasive circles on work with stone;
  • Circles for wood work;
  • Diamond discs (which were mentioned above).

The purpose of each of the types of disks usually corresponds to its name.

In the middle of the grinding disks, four main subtypes are distinguished. petal, wire, diamond and grinding wheels at the bakelite base (straight, T41 and plate profile, T27 profile).

  • The petal disk is made of sandpaper. Its main purpose. This is the liquidation of an existing coating, such as ancient paint, a primer in another layer of coating. Also, disks of this species are grinded wood products.
  • Wire discs are used by masters to remove rust. They also have an option to remove other types of persistent pollution.
  • Diamond discs are used for polishing work on stone.
  • Melt discs are made of plastic or rubber and consumed for polishing metal.

The main question: how to choose the right disk for corner grind?

Choosing equipment for angular grinding, first, for you it should be due to the type of proposed work. For this reason, the choice of the type of disk directly depends.

We also wish to mention that when choosing a consumable for yourself, be sure to take into account the powerful properties of each specific model. Study the marking.

Often, it is applied to the disk itself and contains a set of signs by which it is possible to find the relevance of this consumable to perform the alleged work.

Also, focus your attention on such a parameter as a disk diameter. It should not exceed the size of the protective casing on a specific tool model.

The dimensional row of disks is usually represented by subsequent dianeals: 115, 125, 150, 180 and 230 mm. The most all.prevailed diameters. 125 mm. and 230 mm.

They are optimal for most types of work and the abilities of the tool itself.

As for the thickness of the disks for metal, stone, it often varies from 1 to 3.0 mm. cutting wheels). According to many masters, we can conclude that the thinner the disk, the more convenient it is to work. This, of course, is so, but do not forget that when working with a low thick disk, its fragility and risk of failure of the entire tool increase.

Among bake.based grinding disks, 6.00 mm thick disks are most popular. This parameter depends on the overall disk diameter. The dependence is as follows: the larger the diameter of the disk, the greater its thickness and vice versa.

How to put a disk on a corner grinder correctly?

In order to correctly put the disk on the corner grinder, it is worth noting that the disk is installed on the corner grinder spindle using a special clamping flange with M14 thread. Let’s take a closer look at how to remove a disk from a corner grinder.

In order to unscrew the disk from the corner grinder, you first need to dismantle the flange. Especially for such purposes, manufacturers complete the corner grinder with a special track key. It has a specific form.

The pins located on the horns of this key are inserted into the specially provided holes on the flange.

To unscrew the flange, fix the spindle. To do this, clamp the lock, which is usually the button on the upper part of the case. When pressing, the codium is placed in the hole of the ledge of the gearbox, and this, in turn, prevents its rotation.

Next, we insert the keypads of the key into the specially provided holes on the flange, by clicking on the latch, it is necessary to simultaneously turn counterclockwise and shift the flange from the place.

Rozhki key and end head

To dismantle the tightened fixer, the corner grinder can be applied to 17 and a 24 end head. However, they will have to finalize them before such non.standard use. The wrench must flow to a thickness of 4 mm, and braid the protrusions for holes on the head of the corner grinder on the head.

Dismantling is as follows. The key is inserted under the abrasive, and the end head is put on the flange. Further, both tools must be crank in the opposite direction from each other. After that, the nut should get out without any effort.

These devices often replace a special tool, or are used as an addition. They are many times easier to loosen the clamp of the abrasive disk than the standard option.

How to unscrew and correctly put a disk on an angular grinder

This simple operation sometimes at a standstill of even experienced locksmiths or users of corner grinder. The reason is that the disk is fixed by a special nut. There are 2 or 4 holes on the nut, into which a special key is inserted. This key has always been attached when buying a corner grinder. Perhaps he is still included in the sets.

According to the instructions for the corner grinder, click on the latch, which is located on the back of the gearbox. When the shaft is fixed, you need to unscrew the nut with a special key and change the disk. But it is difficult to promote the nut if it was not squeezed. And pinches it with such a nut almost always. An attempt to unscrew the disk leads to a breakdown of the fixator outside the gearbox.

What exit from the problem is offered by specialists and amateurs

  • Install a gasket from a newspaper under a nut;
  • Install a gasket from a plastic bottle under a nut;
  • Replace the nut with a nut of another design.

What is the gasket from the newspaper.

This is a paper washer in size of the nut. It is put on the installed disk, and a nut is wound on top. This piece of paper was a stumbling block, because the safety inspection always broadcast about the harmfulness of such a decision.

In the same way, representatives of the safety bodies and the installation of gaskets from any other materials are included:

But there is a solution that does not contradict the requirements of safety precautions, and allows you to normally install and remove the disk. This is a special nut that consists of two elements. a nut and a clamping washer. The use of such a nut does not require any linings, because the disk does not jam with it.

If there is no special key at hand, then craftsmen offer to do without a key. This does not mean that you can do without a key, but use a “gas key” or other device. To do this, you need to clamp the lock, clamp the nut with a gas key and unscrew it. So you can replace the jammed disk, but this is a very uncomfortable operation for one person.

There are offers to clamp the disk with your hand and so unscrew. Maybe, but it is hardly possible to change broken disks. It is better to use the keys that are designed to remove and install disks.

Some foreign firms manufacturers of power tools, such as BOSH, produce corner grinders with light.removable nuts. They securely fix the disk on the instrument shaft, easily and quickly removed to replace the disk.

How to remove a snapped disk from a corner grinder

The use of new nuts solves the problem of disk removal, but what to do with the already snack disk? Even if the disk was installed correctly, it does not always work out to remove it. Practice tells different solutions to the problem.

You can clamp the latch and hit through the extension on the holes of the nut in the direction of unwinding. This option is possible only with a good fixer. But the fixer may not withstand such a solution to the problem and break.

The second method is more logical. Under the clamping nut and the lower support washer, there is a gearbox shaft with set chamfers. The lower support washer is put on them. The standard wrench cannot be installed there. it is very narrow. But you can take a regular face key on “17” and grind it on both sides.

The shotted key will be included in the gap, set on the chamfers of the shaft and fix it. Now, by any key, any nut will be unscrewed, and the disk or its residues are removed from the corner grinder.

How to put a disk on a corner grinder correctly

Grinding wheels have different diameters, different thicknesses and different purposes. Some are made for metal processing, others are processed, and others work on wood.

A disk of such size that will not exceed the size of the protective casing should be installed on the corner grinder. The size of the installed disk is indicated in the instructions and on the marking table of the corner grinder.

The thickness of the disk is selected according to the technological parameters of the processed material. All discs (grinding circles) have their own classification. The shape of the disk, the abrasiveness of the material, granularity, hardness, accuracy class and the class of imbalance are classified. It is the last meaning that some discs begin to beat during work.

The grinding circle has the front and reverse sides. The front side is considered the one on which the marking and the manufacturer is applied to the manufacturer. When installed on an angular grinder, the front side should be located on top.

The disk is installed in this way. So that during the operation of the spark with particles of the processed material flew towards the working. This is due to the issue of safety precautions. If the corner grinder breaks out of the hands, then it will not fly towards the employee.

Therefore, to work with a corner grinder, it is necessary to put on protective clothes or a dense apron. Eyes and open parts of the face must be protected with a mask or at least with protective glasses.

Inertial unscrewing

Install the screwdriver in the groove of the mounting washer angular grinding, in the direction counterclockwise.

Then, press the lock so that the disk does not rotate.

And hit with a hammer on the end of the chisel handle.

The essence of this procedure is as follows: inertial energy transmitted from the hammer to the chisel and from the chisel to the fastener, in the direction of unscrewing the tightening will break, and the puck can be easily unscrewed with hands.

NOTE:

The tool that is installed in the groove of the mounting washer of the corner grinder should be preferably with a blunt end, otherwise the grooves will be very quickly broken, which will bring the fasteners to unusable.

Twisting occurs in the same way, but in the direction counterclockwise, t.e. towards twisting.

How to change a disk on a corner grinder? Step-by-step instruction

To work with the corner grinder, you must first install, and after that, if necessary, change the disk on the corner grinder.

To change the disk on the corner grinding, it is necessary to unscrew the fastener.

The fasteners, as a rule, goes with special grooves, and you can unscrew it only by the corresponding key, which is usually included in each corner grinder.

NOTE:

On some corner grinder, ordinary nuts are installed as fasteners, which can be unscrewed with an open key.

To unscrew the fasteners in its grooves, you need to install the angular grinder key.

On the other side of the corner grinder, press the stop button to fix the rotor in a stationary state.

Next, you need to turn the key against the watch arrows.

So the fasteners are unscrewed, then the old disc changes to the new.

After installing the new disk, first the fastener is twisted with the hands, and in the end it is tightened with a key.

After all the manipulations described above, the corner grinder is “charged” with a new disk and you can start work.

In the case when there is no special key, to remove the disk and replace it with a new one, you can use improvised means, namely, use a large screwdriver or its analogue, for example, a dumb chisel or t.P.

The essence is the next, set the end of the screwdriver in the groove for a special key in the direction of unscrewing, we also fix the lock so that the disk does not spin, and with sharp, not very strong but sufficient force by blows on the back of the screwdriver, we unscrew the disk.

I use this, about the problem of unscrewing. forgot.

An interesting thing. Really looks like a two.hay flywheel in miniature.

Workers usually put a cardboard from a pack of cigarettes under the nut

But do not take root on real objects. (lie in a box).

Such a nut is heavier and a little more than usual. Often it interferes and critically.

An ordinary nut can also be delayed and released without a key if you pull the disk, you just need to be attached and a little experience.

PS of the corner grinder is different, for example, Hilti 125 has a very sharp stop, as a result, the nuts are spinning and fly away with the disk.

Never prevented. If you catch a wedge, you will not unscrew every gas. Especially if the disk occurs, then what to pull for. Nothing has flown away, everything works norms, nothing lies in the box, there are no boxes in principle.

I speak from experience (personal observation of others). Now I have 3 pcs. Corner grinder 125mm. The wired professional Bosch has such a nut in the kit and 2pcs Hilti, to which I bought these nuts They are of course very comfortable, but in fact, no one uses these nuts.

On a vapid, in favor of a regular nut:. a quick.and.packed nut more with a diameter, rests and cannot clamp some petal grinding wheels (with a skin) All lazy people, as a rule, have a sawing disk until they are being applied A quick.packed nut begins more. it begins to interfere with earlier The tile uses a diamond disk, the mass on the shaft there is less, the more jewelry.

which, unscrew, corner, grinder

And by the way, if the disk lifted up and there was a blow, it is not a fact that the quick.packed will turn away with his hands. (need a key). And so the nut is very good when, slowly for myself, I use sometimes.
