The angle grinder today is much more functional than a few years ago, when the tool could be useful only for grinding work. Today, these devices are indispensable in metalworking and construction. Externally, the angle 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 to 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.
What is angle grinder for?
Having considered modern angle grinders, you will note that they are able to cope with a variety of tasks, including:
- Cutting of glass, tile, 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 the angle grinder
In order to understand how to work the angle grinder, you should familiarize yourself with the assortment of nozzles, among which. Brushes and circles. The first are intended for polishing and cleaning surfaces. In this case, it is possible to polish the welds and clean the metal from rust. Depending on the composition, different circles may be used to perform different tasks. Some can cut ceramics, while others are suitable for metal. You can familiarize yourself with this information by reviewing the instructions on the disc or packaging.
Which angle grinder to choose
If you are faced with the question of how to work the angle grinder correctly, then you should know that not only nozzles, but also angle grinders are different. They are presented in different classes, including:
The latter option is suitable for operation for a limited time every day. A professional angle grinder is able to work for several hours every day. As for industrial equipment, it is a device that works almost tirelessly. Tools differ in appearance. Thus, the housing can be supplemented with one or two handles, as well as vibration-absorbing handles.
Operational Safety Angle Grinder
Before you begin the workflow, you must prepare the tool. For this, a circle is selected and set. The motor has a certain power, it provides for the need to choose a circle of certain sizes. The smaller the circle, the greater the rotation speed it is capable of supporting. If you use the wheel incorrectly, this will cause equipment wear and deformation of the nozzles.
If you are thinking about how to use the angle grinder in order to avoid injuries, you should know that discs that are larger than those for which the unit is designed should not be mounted on the tool. Nozzles must not be deformed. If cracks or potholes appear on the circle, then they should be disposed of. Do not use circles that have deviations from the original shape.
Rules and recommendations
After securing the wheel, the tool should be started and checked at idle. Within 30 seconds, the equipment is driven 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 work.
Quite often, beginner home masters ask themselves how to use an angle grinder correctly. Before starting the manipulations, the operator should prepare himself, for this you need to wear:
- Special clothes;
- Safety glasses or mask;
- Tight gloves.
The operator needs to remove all jewelry, for example, watches and bracelets, because they can be wound around a circle. You can’t start work if you are tired or intoxicated. The use of saw blades for wood is excluded when working with an angle grinder.
Fire safety and fastening parts
The operator needs to make sure that no one is in the cutting plane. Until the disk stops completely, you must not let the tool out of your hands. Do not touch the equipment before it cools down. There should not be any flammable objects in the working area, namely:
If you are interested in the question of how to work the angle grinder correctly, then you should think about reliable fastening of parts. Everything that is processed and cut must be fixed. As an exception, there are elements that will remain motionless under the influence of their own weight, plates and stones should be included here. The part can be fixed in a vice. If this is not possible, you should use the help of a partner who will fix the workpiece or pipe with an adjustable wrench. It is forbidden to hold the workpieces in your hands.
How to cut an angle grinder
Many owners of the described equipment in the early stages of its operation are interested in the question of how to properly operate a small angle grinder. It is worth noting that the technique for cutting a workpiece in this case is no different from the one when a professional-grade tool is used in the work. Workplaces need to be cleaned, the workpiece must be marked out, only then can you start work.
The equipment must be held with both hands. If a jam occurs, the tool must not be pulled out of the hands. You should always be prepared for a back strike, which can cause a strong displacement. In general, a kickback is one of the most dangerous moments when operating an angle grinder. In this case, a sharp sudden rejection of the tool occurs when the disk is jammed in the workpiece.
What else should I definitely mention when talking about how to work the angle grinder correctly? Where sparks fly in the process of carrying out certain manipulations. This is what the master needs to follow. They should not fall on the face, legs and clothing. It is important to make sure that the power cord is out of range of the drive. If you want to move to another object, then first turn off the equipment and drag the cord. If there is a power outage, the device must also be de-energized. It is very important to understand the question of how to work the angle grinder correctly. On your own or on your own. The answer to this question will be the following statement: the movement of the tool and the direction of rotation of the disk must coincide. However, sparks will close the markings. For this reason, the operating rules are often ignored, but in vain. In order to prevent jamming of the circle, the disk should be introduced into contact with the workpiece at full spindle speed.
Basic rules for cutting
When cutting blanks, it is important to make sure that you follow the basic rules. The fishing line should pass by the person, but not rest against him. If a jam occurs, the reactive movement of the equipment will bypass the operator. It is important to provide protection with a casing. It should be located between the employee and the circle.
There is no need to press the tool excessively. The unit will be able to cope with tasks using its own weight. While overload will cause a skew circle. The inclusion of an angle grinder when the disc is in the workpiece profile is excluded. Start cutting the profile from the point where the cross section is the smallest.
It is important to remember that when cutting tiles, concrete and stone, a lot of dust will form. Respiratory organs should be protected from it. Some manufacturers produce casings with a nozzle for a vacuum cleaner. Dust can be suppressed with water, directing the jet into the cut. If you need to work on cutting walls, you should be prepared for the fact that under the circle fittings, pipe or cable may fall. This will certainly cause a back strike. In order to exclude injuries, it is necessary to be away from the equipment displacement line.
Even before acquiring the equipment described in the article, you should learn all about how the angle grinder should work properly. This applies not only to the operating instructions for the instrument, but also to the sound that accompanies the operation of the unit. It should be even; make sure it is worth putting on the disk. You should not hear and feel superfluous sounds and vibrations during the work. Sounds of pops, extraneous odors and heating of the case are excluded. If you have noticed such signs, then the tool is best exchanged.
