Intensive work with chain saws inevitably leads to the loss of working qualities of cutting equipment. Only the experienced craftsmen with the proper dexterity can restore the geometry and former sharpness of the saw segments with the usual tool. But even with the help of a file and a grinding disk, they eliminate only minor flaws. A full-fledged dressing with optimal grinding characteristics is performed by a chain sharpening machine, which has a design and functional support suitable for such purposes.
Unit design features
The equipment is compact and ergonomic enough for use at home. On a strong bed there is a control panel with a start button, a sharpening depth limiter and a designated scale for adjusting the angle of processing. The direct mechanical impact is exerted by a movable head with a disk. The functional body with the abrasive adjusts to the desired sharpening parameters and, after starting, starts processing. Since the machine for sharpening chains of chainsaws performs operations at high speed, a set of protective devices is also provided in the design. These include a casing in the direction of the operator, a wedge with a chain lock, as well as powerful set screws that maintain the stability of the equipment.
Before processing, the chain of the chainsaw is fixed in a special holder, after which the user adjusts the angle of abrasion. Next, the circle is sent to the chain from the top for the handle and sharpening begins. After that, the wizard only needs timely movement of the links - each segment is processed separately.
Varieties of machine
The entire modern range of this equipment can be classified according to two criteria: the installation method and the degree of automation. As for the first sign, mobile and stationary units are distinguished. At large workshops and production enterprises, the tool is serviced on stationary, that is, devices permanently fixed in one place. A mobile chain sharpening machine is advantageous in that it can be used away from the maintenance site. Such equipment can be useful in the country, in the conditions of logging, etc. This is an independent unit from the network, with which you need to work manually.
And here you can go to the second sign - the degree of automation. Manual models are installed on the saw blade, after which the master independently grinds the abrasive bar, making reciprocating movements. Automatic machines with an electric motor, as already mentioned, connect a grinding wheel for work, which rotates due to the drive mechanism.
Equipment performance
Processing speed is the most important parameter of the machine, which determines not only the speed of sharpening, but also the quality of the result. This value depends on the number of spindle revolutions, which varies on average from 3000 to 7000 rpm. For infrequent work in the household, you can buy a model with low speeds, but regular maintenance of chains in the production will require a high sharpening frequency.
The diameter of the grinding wheel also matters. The dimensions of metal segments depend on it, which, in principle, can be processed by a machine for sharpening saw chains of a specific model. In this case, we are talking about equipment for gasoline units, and these are, as a rule, large-format elements. For example, 400 mm discs can handle blades up to 105 mm.
Considered in the selection and engine power. In principle, high-precision grinding equipment does not require. For domestic operations, an aggregate with a power plant of up to 100 W will be enough, and industrial stations rarely reach 850 watts in power. As for voltage, almost all representatives of the segment work with single-phase 220 V networks.
Reviews about the model "Trailer SZ-150-250"
Small-format domestic unit that can be used in small workshops and in the household. As user reviews show, the equipment is well-assembled, has a high working resource and provides sharpening worthy of characteristics. In particular, many indicate exposure to the correct angle and the absence of random deformations. The advantages include the cost of the machine for sharpening chains. The price is one of the lowest in the segment and amounts to about 1800 rubles. At the same time, the power potential reaches 250 W with the support of maximum revolutions of 7500 rpm. But that is not all. The machine comes with a wide set of equipment, which includes an adjusting key, fixing bolts and an abrasive disk.
Rezer EG 180-C Reviews
It’s also a budget model, which can be considered as a universal tool for sharpening saw chains. The owners of the machine indicate its technical reliability, productivity and ease of management. In terms of physical ergonomics, this is one of the best models in the segment. To this, it is worth adding the presence of a cast support in a structure with holes for bolts. However, as practice shows, a reliable bed, even without special fixation, without deviations and fluctuations, is able to hold functional equipment in the process. The high quality of the processing result is another significant plus, which is noted in the reviews. The chain sharpening machine EG 180-C can be rotated with a working platform, which also increases the convenience of operation of the unit. If we talk about the shortcomings, then among them there is a low level of maximum speed and overheating during prolonged use sessions.
Reviews on "Caliber EZS-220"
A higher class model that can be used in critical chain saw maintenance jobs. And not only equipment for gasoline models, but also paintings from electric models. The design also provides a rotary table, and the size of the grinding element is 100 mm. The reviews note the confident operation at high speeds up to 7500 rpm, the correctness of the endurance of the sharpening angle and the effective function of the limiters, which strictly regulate this machine for sharpening chains. The price of the unit is about 2 thousand rubles. Given the wide range of accessories, this is an acceptable amount. Another thing is that the owners explain the low cost of the model using plastic in the design. Therefore, many decide to modify the design due to metal pads and soles.
Einhell GC-CS 85 Reviews
Einhell is well known for its gardening equipment and power tools. In this case, it is proposed, albeit a low-power, but reliable and reliable machine for sharpening chains of chainsaws, the price of which is 2.5 thousand rubles. We must immediately emphasize the combination of a modest power potential of 85 W and a circle speed of up to 5500 rpm. But, despite these figures, the model is highly appreciated by the owners for accurate assembly, high quality parts and precise grinding.
DDE MSC-104-95 Reviews
The most expensive model in the review, available on the market for almost 3 thousand rubles. What does the manufacturer offer for this money? Compact machine for single-phase network with voltage deviations up to 10%. The device is widely used both in domestic conditions and in specialized enterprises - logging, construction sites, repair shops, etc. This machine for sharpening chains also does not indulge in high power indicators (95 W), but it facilitates the operator’s tasks in control and control actions. In the first place in the list of advantages, users put ergonomics, followed by sharpening speed and compact size. Among the shortcomings there is a limited service for large-format equipment.
How to make a machine for sharpening chains with your own hands?
In a garage, you can make a machine from a metal platform with a work table, an electric motor and accessories for attaching the grinding wheel. For the bed, you need to take a thick sheet or several brazed stainless steel panels. Bearing elements for the engine and related electrical equipment are welded to this base. An asynchronous motor can act as a motor. Next, you can proceed to the adjusting snap, which will provide the ability to install a locking structure.
The workpiece is fed by an inverter welding machine or mounted on hardware with your own hands. The machine for sharpening chains of chainsaws during operation will be controlled mainly by manual manipulations without automation. For example, the contact of the abrasive with the eyeliner to the chain segments rests entirely with the operator, therefore, the quality of processing will depend on him. The power plant is only responsible for the operation of the grinding disc.
Implement Tips
Start sharpening only after checking the technical health of the equipment. Checked electrical connections, mechanical fasteners, as well as the condition of the abrasive. The link line is fixed in the loading chute and, depending on the design of the machine, is clamped or simply pulled under sufficient force. At the same stage, the sharpening angle should be accurately verified, having previously estimated the condition of the links. These parameters affect not only the intensity of the mechanical impact on a particular side of the segment, but also the geometry of the dressing. After the end of work, the machine for sharpening chains is turned off, the serviced workpiece is removed and, if necessary, disassembled. Many manufacturers recommend removing the protective cover, accessories and guides after each operating session - this makes it easier to check the status of functional organs and equipment systems.
Conclusion
The special shape of the tooth in the cutting blades of chain saws is the key to the effectiveness of their use. From the harvesting of firewood in the country to the felling of the forest - all these operations with wood are best performed by this particular technique. Therefore, the tool serving it is of no small importance. Which chain sharpening machine do you prefer? For everyday tasks, you can restrict yourself to simple budget models with a small power of about 100-150 watts. In the workshop and in production it is better to use productive stationary models, which are also provided with modern protective systems and the latest ergonomic functionality. However, their cost will be higher.
