Exact operations on the decorative processing of wooden surfaces can only be obtained using special drills - engravers. As a rule, these are small devices that allow the master to create all kinds of patterns on the work site. In addition to the main function, a wood engraver is also capable of cutting, grinding and drilling. Such optional filling usually refers to multifunctional devices, the set of which includes the corresponding nozzles.
The device and principle of the engraver
Models from budget families designed for amateur use usually have a simple device. Their design, in particular, provides a housing with an engine and related components, a mounting nut for the working shaft, a fixing spindle, control buttons , etc. Expensive multifunctional wood engravers are provided with similar components, but in a higher quality performance.
As for the principle of work, it is also quite simple. The motor makes the shaft rotate, which, in turn, is equipped with a nozzle suitable for a particular operation. Depending on the characteristics of the functional element, a corresponding treatment of the wooden surface takes place. This can be the formation of holes, and the creation of patterns with patterns. Typically, wood engravers have a set of accessories designed for a specific direction of work. Further, it all depends on the skill and imagination of the user.
Main characteristics
The device is simple, therefore, it has few technical characteristics. The main attention should be paid to the power and the number of revolutions of the motor. Power potential varies from 130 to 170 watts. Powerful wood engravers are rarely acquired to perform decorative operations, since in this case the ergonomic advantages of the device come to the fore. The number of revolutions can reach 30-35 thousand per minute. Actually, 20 thousand rpm is enough for wood, but if you plan to work with stone or concrete, then you should focus on more productive models.
The importance of the ergonomics of the engraver has already been noted. This characteristic is determined by the mass of the device, the convenience of the handle, the presence of auxiliary devices and the configuration of the arrangement of the controls. Experienced users always check how comfortable wood engravers are, even at the selection stage. It will be useful to make several manipulations with the device or just hold it in your hand. Such acquaintance with the tool is very important if it is planned to carry out delicate jewelry precision work with it.
Power tool
In this parameter, everything is quite simple. There are two principles for the power supply of engravers. The first involves the use of a traditional electrical connection, and the second - a complete battery. The advantages of electrical devices include lightness and comfort during operations. Despite being tied to a power outlet, such a device is very convenient to use in a permanent workplace. If you plan to carve a wood engraver outdoors, then you can not do without a battery. Typically, these elements provide hours of work and provide complete freedom of movement. But the presence of the battery in the design inevitably makes the apparatus heavier and makes it less maneuverable - this nuance will be felt when cutting. A good alternative to these options can be a combined model that runs on power and battery.
3D wood engraver - what are the features?
This is a special category of devices for engraving and cutting, which are massive structures with electronic filling. Such systems are connected to computers, after which, using a special program, the future pattern is modeled or the cutting parameters that are planned to be formed are formed. It is important to note that a 3D wood engraver does not require human involvement in the work process. It performs operations with high accuracy automatically - in accordance with a digital sketch, which was previously assigned for execution. As a result, it is possible to obtain, for example, a highly accurate complex pattern, but the cost of such equipment is several times higher than the price tags for conventional hand-held devices.
Manufacturer's Reviews
Although the segment is narrow, well-known manufacturers are represented in it quite widely. Owners of such devices leave a lot of positive feedback about Dremel products. The advantages of a convenient handle, a long cord and a wide range of delivery of models presented in the middle category are emphasized. By the way, such a wood engraver is estimated at 2.5 thousand rubles. Serious successes in this niche are also shown by Sturm, whose models are praised for their high build quality, the optimal combination of functionality and power, as well as for their attractive design. Domestic engravers are also present on the market - in particular, the Zubr and Caliber devices. These products should be addressed in cases where you need an inexpensive model with a minimum power rating within 145 watts.
Conclusion
Modern technology allows interested users to perform the most complex tasks associated with cutting wooden products. There are two categories of such equipment. Specialized machines for construction tasks are most in demand, which are used to obtain material with the desired parameters. The second, less popular group just includes a wood engraver that allows for more precise decorative operations. Despite the popularity of automated laser machines, manual devices are still relevant. It is these devices that allow you to maximize the creative vision of the master of curly cutting. And not always engravers are acquired by experienced users. In their arsenals, ordinary connoisseurs of original arts and crafts have a similar tool.
