The angle grinder today is much more functional than just a few years ago, when the tool could only come in handy for grinding work. Today, these devices are indispensable in metalworking and construction. Outwardly, the grinder looks unpretentious, it has a cylindrical body, on one side of which there is a handle, and on the other - a mount for nozzles. It is the nozzles that make this unit multifunctional. They are fixed on the spindle, while the discs are additionally fastened with a clamping nut and a flange. This measure is mandatory when working with the described tool.
Why do we need angle grinders
After considering modern angle grinders, you will notice that they are able to cope with a variety of tasks, including:
- cutting glass, tiles, stone, plywood, concrete, brick and metal.
For each type of work and material, a specific abrasive tool should be used.
General recommendations for working with an angle grinder
In order to understand how to work with a grinder, you should familiarize yourself with the range of nozzles, including brushes and circles. The first are intended for polishing and cleaning surfaces. In this case, you can polish the welds and clean the metal from rust. Depending on the composition, different circles can be used to perform different tasks. Some can cut ceramics, while others are suitable for metal. You can find this information by looking at the instructions on the disc or packaging.
Which grinder to choose
If you are faced with the question of how to properly work with a grinder, then you should know that not only nozzles are different, but also angle grinders. They are presented in different classes, among which:
The last option is suitable for operation for a limited time every day. A professional angle grinder is able to work every day for several hours. As for industrial equipment, it is a device that works almost tirelessly. The instruments also differ in appearance. Thus,the case can be supplemented with one or two handles, as well as vibration-absorbing handles.
Safety precautions for the operation of the angle grinder
Before starting the workflow, you must prepare the tool. To do this, a circle is selected and set. The motor has a certain power, it provides for the need to select a circle of certain sizes. The smaller the circle, the greater the speed of rotation it is able to maintain. If the wheel is not used correctly, it will cause equipment wear and deformation of the nozzles.
If you are thinking about the question of how to work with a grinder in order to avoid injuries, you should know that disks that are larger than those for which the unit is intended should not be installed on the tool. Nozzles must not be deformed. If cracks or potholes appear on the circle, then they should be eliminated. Do not use those circles that have deviations from the original shape.
Rules and guidelines
After fixing the wheel, the tool should be run and checked in idle mode. For 30 seconds, the equipment runs at maximum speed. If you have not noticed extraneous sounds and vibrations, and the protective cover does not touch the disk, then you can start working.
Quite often, novice home craftsmen wonder how to work with a grinder. Before starting manipulationthe operator himself should prepare himself, for this you need to wear:
- special clothing;
- goggles or mask;
- tight gloves.
The operator must remove all jewelry, such as watches and bracelets, as they may be wrapped around the circle. Do not start work if you are tired or intoxicated. Eliminated the use of saw blades for wood when working with an angle grinder.
Fire safety and fixing parts
The operator needs to make sure no one is in the cutting plane. Until the disc stops completely, do not release the tool from your hands. The equipment should not be touched before it has cooled down. There must be no flammable objects in the work area, namely:
If you are interested in the question of how to work with a grinder, then you should think about secure fastening of parts. Everything that is processed and cut must be recorded. Exceptions are elements that will remain motionless under the influence of their own weight, this should include slabs and stones. The part can be fixed in a vise. If this is not possible, you should use the help of a partner who will fix the workpiece or pipe with an adjustable wrench. Handling workpieces is prohibited.
How to cut with a grinder
Many owners of the described equipment at the first stages of its operation are interested in the question of how to work with a small grinder. It is worth noting that the technique for cutting the workpiece in this case is no different from the one when a professional-class tool is used in the work. Workplaces must be cleaned, mark the workpiece, only after you can start working.
The equipment must be held with both hands. If the wheel becomes jammed, the tool must not be pulled out of the hand. You should always be prepared for kickback, which can cause a lot of displacement. In general, kickback is one of the most dangerous moments in the operation of an angle grinder. In this case, a sharp sudden rejection of the tool occurs when the disc jams in the workpiece.
What else should I definitely mention when talking about how to work as an angle grinder? Where sparks fly in the process of carrying out certain manipulations - this is what the master needs to follow. They should not get on the face, legs and clothes. It is important to make sure that the power cord is out of reach of the drive. If you want to move to another object, then the equipment should first be turned off and drag the cord. If there are power outages, the device must also be de-energized. It is very important to deal with the question of how to work as an angle grinder - for yourself or for yourself. The answer to this question will be the following statement: the movement of the tool andthe direction of rotation of the disc must match. However, sparks will cover the markup. It is for this reason that the rules of operation are often ignored, but in vain. In order to avoid wheel sticking, the disc should be brought into contact with the workpiece at full spindle speed.
Basic cutting rules
When cutting a workpiece, it is important to make sure that you follow the basic rules. The cut line should pass by the person, but not rest against him. If the disc jams, the jet movement of the equipment will bypass the operator. It is important to provide protection with a casing. It must be placed between the worker and the circle.
It is not necessary to apply excessive pressure to the tool. The unit will be able to cope with tasks using its own weight. Whereas overloads will cause the circle to skew. The inclusion of the angle grinder is excluded when the disc is in the profile of the workpiece. Start cutting the profile from the place where the smallest cross section.
It is important to remember that when cutting tiles, concrete and stone, a lot of dust will be generated. Respiratory organs should be protected from it. Some manufacturers produce casings with a nozzle for a vacuum cleaner. You can also suppress dust with water, directing the jet into the cut. If you need to work on cutting a wall, you must be prepared for the fact that fittings, pipe or cable can get under the circle. This will certainly cause a backlash. To avoid injury, stay away from the equipment offset line.
Morebefore purchasing the equipment described in the article, you should learn everything about how the grinder should work correctly. This applies not only to the instruction manual for the tool, but also to the sound that accompanies the operation of the unit. It must be even; it is worth making sure of this by putting on a disk. You should not hear or feel extra sounds and vibrations during operation. The sounds of pops, extraneous odors and heating of the case are excluded. If you have noticed such signs, then it is better to exchange the instrument.
