Emery machines: description, types, features, instructions and references

The cutting tool needs regular maintenance to maintain performance. Hand tools to perform a quality grinding or grinding operations is impossible. For this, special equipment is used, provided with appropriate abrasive elements. As a rule, for such tasks, abrasive machines are used, in which equipment a sharpener is provided. There are also compact models for household needs, and industrial modifications with increased performance, so choosing the right option will not be difficult.

General information about sanding machines

On the device such equipment in many respects reminds traditional cutting-off saws. However, there are significant differences in the working bodies. The mentioned sharpener can be represented by abrasive wheels with different parameters of grain size, thickness and diameter. These parameters largely determine the belonging of the plant to a certain class of equipment. The range of functions that the unit is able to perform depends on the characteristics of the circle. For example, a grinding-emery machine is supplied with a fine-grained tape, and to perform a full-scale grinding, it is necessary to use models supporting work with disks for rough machining.

The power of the machine, which varies from 200 to 1000 W, is also important. This indicator affects the ability of the equipment to perform operations with different materials. For example, the higher the power, the more efficient the processing of metal products. And on the other hand, if only decorative or external surface finishing is planned in the form of disposal of burrs and minor defects, then a small power within 500 W is enough.

Structural features

The main difference between the device of such machines is the configuration of the cutting elements. The unit can be supplied with two disks or a combination with a circle and a grinding belt. As a rule, masters are trying to implement a combination of processing components that perform different functions. So, if you plan to sharpen a heavily deformed or a new tool, then at the first stage a coarse-grained disk can be used, after which a grinding belt comes into operation providing final finishing of the surface to the optimal state. In most cases emery machines provide perpendicular arrangement of one working element in relation to the second one. This configuration, as the experience of specialists shows, is the most profitable from the point of view of the operator's convenience, and in terms of the quality of the result.

Types of equipment

The main classification involves the separation of machines according to the nature of the processing activities. The most common universal unit, the functional capacity and power is enough to perform a full range of grinding operations. Also familiar to many craftsmen grinding machine, which is focused on the processing of high-speed steel tools. To the specialized equipment it is necessary to include also sharpening units with which help complex processing of chains is carried out. Also, an emery grinding machine is classified according to the type of installation. Two types of models are distributed - desktop and floor. The first option represents a group of medium-power household appliances that perform simple tasks of grinding and sharpening. Floor models, however, have a more massive structure, they have high capacity and, as a rule, are used in enterprises in the mode of continuous operation.

User's manual

Virtually all grinding and grinding operations are performed in two stages. First, the operator must form a smooth chamfer. It is important that the edges turn out to be sharp, without any burns or rounding. The main task at this stage is to perform the grinding of the surface from the right sides so that an optimal cutting edge is formed. This will allow the second stage to form a blade with the necessary parameters. So, in the second stage, sanding machines are used for the purpose of making edits. This is achieved by sharpening the blade and giving it the necessary sharpness. In addition, in the same part of the event, the operator eliminates possible defects that were left in the process of forming the edge. This can be roughness, burrs and various irregularities, which are eliminated by grinding at low speeds.

Maintenance Instructions

Capital maintenance provides for a complete analysis of the machine with a thorough revision of the technical filling. The state of the motor, as well as associated components and components, is checked. Separate attention deserves the condition of the hull and its parts. It is important not to forget that the strength and reliability of the design of such units directly affect the safety of the work process. Before each working session, the disks are also checked. The state of the circle is evaluated not only in appearance. Professional masters run emery machines with disks and listen to them for the presence of beats. In fact, this is an analysis of the increased vibration, which may indicate unevenness in the edges of the disk. You can correct the situation with a diamond pencil or cutter. These devices remove from the circles of excess, thus reducing the deviation during rotation.

User feedback on sanding machines

Given the correct choice of the machine in terms of the functions assigned to it, users in most cases manage to achieve the expected results. Especially the owners praise the high-power model. Such equipment is devoid of shortcomings of low-power units and, as a rule, can be used as a universal equipment. These units include the sanding machine floor, which covers the whole range of grinding and grinding operations. True, the cost of such models is quite high.

Manufacturers and prices

The assortment is wide and contains products of many popular brands of the construction market. The most deserving offers can be found in the Bosch, Makita, Metabo and Hammer lines. As for domestic production, this category is represented by companies "Energomash", "Zubr", "Interskol", etc. The cost varies on average from 1.5 to 7 thousand rubles. At the same time, it is important to take into account that the emery table-topping machine, whose price does not exceed 2 thousand rubles, is more likely to be able to provide simple grinding operations. For serious sharpening it is necessary to be guided by the foreign technics in cost from 4-5 thousand rbl.

Conclusion

Emery machines are a very conservative type of equipment. Their working principle leaves little room for the introduction of high technologies and even automated systems. Therefore, the main direction in which the most popular grinding machine is improved is to increase the reliability of the construction and the accuracy of the work operations. To this end, manufacturers are using increasingly high-quality alloys for the manufacture of housings, developing effective configurations for the location of functional bodies, and working on security systems. However, there is also progress in terms of ergonomics. In the latest models of machines, for example, there was a highlight and more convenient controls.
