How to sharpen knives at home? This is done very simply, using a special bar or mechanical or electric sharpener. And what to do if you need to sharpen not only knives, but also a half dozen drills, a pair of axes, an edge of a bayonet shovel and a whole bunch of equipment you need in the household? Maybe it's time to buy a grinding machine. Reviews from buyers who have purchased such equipment, allow us to conclude that such a thing will definitely come in handy on the farm.

Specifications

The equipment is characterized by its basic parameters. For grinding machine is the power and speed of the grinding wheel. The first indicator will determine the uptime, the second is the performance. In key features must include the weight of the equipment and its dimensions: as a General rule, the larger and heavier the machine the grinding, the more difficult in setup, installation, transportation and arrangement of the working area. Next is the diameter of the abrasive wheel and the diameter of the disk – these characteristics not only determine the size of the working area, but also serve as a token when buying the tool to replace it.Desktop grinding machine: purpose, characteristics, models

Sharpening bench: classification

All grinding machines are divided into two large groups: table and floor. Today we consider only the desktop, as they have smaller dimensions and are often used in everyday life. Heavy outdoor equipment used in industry, in specialized workshops for the machining of metal.

The grinding and grinding grinding machine is practically the same thing, since any universal grinding machine can also be used for grinding. The word “grinding” is added to the name of this type of equipment mainly when the machine, in addition to abrasive wheels, is equipped with sanding belt.

Power equipment is divided into industrial and domestic. This division is conditional, based on practice, as for household needs, no one will buy an expensive powerful machine with lots of extra features, in which there is no need. Conversely, in industry seldom use compact appliances, which simply will not sustain the load.

The diameter of the circle grinding machine can be small, medium and large. Table grinding machines include small grinding machines with a grinding wheel diameter of up to 175 mm.

Device

The residual design is simple: there is a motor that provides rotation of the abrasive tool, two spindle (under the most basic models – one), which are mounted on circles, shields and sometimes lighting. The workpiece is fed manually. In grinding machines is one of the circles tape.

Manufacturers

Which grinding machine is better, domestic or foreign brand? This question is not so easy to answer. First, all imported is always more expensive, and such equipment has more additional functions. The Russian manufacturer focuses more on the durability of the structure, its durability under high load, but with a minimum configuration and at a lower price.

Manufacturers whose products can be found in: Makita, "Gauge", "Diold", Metabo "anchor", "Interskol", "bison", "Corvette Expert", Optimum, JET and a lot of different brands. The name is not necessary to navigate on it, you never know where and by whom were produced the equipment. For example, the Optimum is the joint product of Germany and China, JET doing in the US, Taiwan and China, "Interskol" – a Russian company, but has factories not only in our country but also in China, but also orders the components in Bulgaria, Taiwan and South Korea, "bison", "size" and "anchor" – a Chinese firm trying to mimic domestic brand, etc.

So if you want to find out exactly where the thing was produced, you need to look into the documents, and even better read the available information about a particular brand.

Selection features

How to choose a grinding machine? It all depends on where it will apply and how often. For example, small models are inexpensive, but they have little power, and therefore, the time of continuous operation, as a rule, does not exceed half an hour, after which it will be the same rest. For domestic purposes this is sufficient, but for miniproject with a heavy workload there.

Another thing to think about is the type of work: exactly which tools will grind and (or) grind, how much overall (miniature) they are and what accuracy is required. With a large variety of types of sharpening, you should look at the models that have the ability to adjust the speed of rotation of the circle. In addition, if the machine has a heartbeat, then it is easy to edit a precise tool with a certain angle of the cutting edge.

If a lot of work is expected on sharpening a monotonous tool, for example, chains of electric and chainsaws, drills, cutters or finishing on a grinding belt, then you need to look at special equipment designed for a narrow range of work, but with high accuracy and performance.
