Grinding machine angular is a relatively new tool a little muddy the past. There are conflicting reports about who invented them, some recognized by German company Ackermann and Schmitt in 1954, while others attribute the merits of Thomas Joseph and claim that it was invented in 1973. Anyway, are a more recent invention than many of them. other widely used tools. Grinding machine angular also have several different names. Can be referred to as a grinding disc or grinder, side .
Depending on model angle grinder can be powered by compressed air, gasoline or electric motor. Are a versatile tool that can be used for cutting, grinding, sandblasting or polishing materials. For each of these different applications will use a particular type of disk . Discs include grinding wheels, grinding wheels, cutting wheels, grinding wheels, abrasive wheels, disks, brushes, and many others.
Plate will be mounted on a stepped head, which rotates at a speed of 4000 rpm to 12000 rpm. Most of them will be equipped with an adjustable lid that will ensure your safety and enable the service in two hands. Angular grinding machine used large bearings to counter side forces generated during cutting.
Grinding machine angular commonly found in many places, from shops and construction sites after the garage automotive and emergency situations. Some typical applications are grinding rust from metal, cutting of metal or concrete, removing paint and polishing of some metal objects. Can also be used for cutting bricks, tiles and removing excess grout.
The choice of the angular grinding machine
People who have just started to use for angle grinders, are often lost when it comes time to buy one because of the available size range. The General principle is that the larger the grinding wheel the better for large problems. The smaller the Board the easier to control. When you see a polishing machine that is marked as grinder 4.5 inch, manufacturer refers to the size of the disk, which takes, not the length of the machine . If you are a homeowner who uses an angle grinder to periodically work at home, enough to have grinding 4.5 inches. On the other hand, if you are a performer who often must cross big beams to work in the car, the best choice would be a big chopper.
When selecting a angle grinder it is also necessary to consider the thickness of the material being cut. The measurement specified by the manufacturer, the diameter of the disk. This means that angular grinding machine with a diameter of 4.5 inches can only intersect the material thickness of 2 inches or less.
More often than not, less grinding machines revolve at high speeds than larger grinders, but it’s not a rule, hard and fast, so you should always check and understand the nominal power of the engine. The more amps the motor has, the faster it will be. You should also consider that a machine with a large disk needs more amps to turn the disk at the same speed as a car with a smaller shield.
This means that the 7-inch grinder with 13 engine-amperowym is he was running about the same speed as a 4.5 inch grinder with the engine 7-amperowym. The faster the machine rotates, the more prone to overheating, so it is better to choose a model that has adjustable speed settings. Thus, you can set the motor so that it rotated at the right speed without worrying about overheating .
How to safely use angle grinding machine
Grinding machine angular are an extremely useful tool, but they can be very dangerous if used incorrectly. Because of this, it is important to follow some safety rules. The three most common causes of injury when working with angle grinders is metal particles that are stuck in the eye of the operator, the impact force of the rotating disc and break it or wybuchanie drive.
To reduce the risk of injury, should take the necessary precautions. First of all, operators should always wear protective eyewear when using an angle grinder. Since angular grinding produce a lot of dust while sanding, it’s good to wear a respirator, and, if possible, work in a well ventilated area. The wearing of work gloves is also a great idea, as it provides another layer of protection from abrasion and cuts.
If you are familiar with using angle grinders, start the machine on lowest speed and run a few test cuts or a small grinding of excess material before beginning work on the project. This will allow for the flair of the machine. When you will feel comfortable with the amount of impact you can increase speed. Not only work, therefore, will be safer, but will also reduce the likelihood of errors in the final draft.
To reduce the risk of explosion of the grinding wheel, verify that the speed limit drive faster than grinding the corner. If you are using a shield at a cost of 6000 rpm./minutes set for grinding rotating at a speed of 10 000 rpm.minutes, there is a high probability that the disk will rupture during overheating.
