The attention of those who like tinkering or doing this professionally, today presented a wide range of various electrical equipment. The electric engraver with a flexible shaft is very popular among designers and repairmen of household appliances. Information about the device of this power tool and its purpose is contained in the article.
Acquaintance
The engraver is considered an ideal tool for processing various materials: wood, stone, glass, metal, etc. This device is universal, because, using a set of milling cutters, they can be ground, milled, engraved and cut material. In addition, holes can also be drilled with this power tool.
Kinds
Depending on the design and method of power supply, the following types of engravers are distinguished:
- drums . In tools, electricity is converted into kinetic energy of impact. Drawings and inscriptions on the surface of the material are applied with special nozzles;
- rotational . They work on the principle of a drill;
- rechargeable . The wizard does not need to plug them into a power outlet;
- flexible shaft engravers . Work using electricity;
- laser . They are large-sized machines. These engravers are floor and table. Depending on the processed material, laser engravers are divided into two types:
- Gas. They are used to work with any materials.
- Solid state. Designed for processing exclusively metal or plastic surfaces. Using solid-state equipment, products are marked and various inscriptions are applied to computer keyboards.
Judging by the numerous consumer reviews, the most popular is an electric engraver with a flexible shaft.
Device
The equipment consists of the following structural elements:
- engine;
- a flexible drive shaft, with the help of which torque is transmitted from the engine to the working nozzle;
- gearbox;
- spindle.
- fan cooling spindle;
- a case equipped with special openings through which heated air comes out;
- nuts. With its help, working nozzles are fixed in the tool;
- lock button;
- power regulator;
- circuit breaker;
- a special hook with which the switched off tool is suspended on the wall.
Operating principle
A flexible shaft electric engraver is a type of drill - it also uses torque. For this device, as well as for a drill, an electric drive is provided, which is necessary to create torque and a high speed of rotation of the working nozzles. But, unlike a drill, an engraver has significantly wider functionality.
Flexible shaft
This device is an integral part of screwdrivers, drills and engravers. A flexible shaft has increased torsional rigidity and less bending rigidity. The design of the device consists of a core on which a wire is wound in several layers.
A special casing provides grease retention and protection of the core from mechanical damage. Due to this design, the flexible shaft is able to bend in any direction. One end is equipped with a special cartridge for the working nozzle. The objective of this device is to transmit torque from the engine to the part.
Application
Using an electric engraver, you can perform various technological operations both at home and in production. This universal device is very in demand:
- In specialized workshops . With the help of this equipment, various models and souvenirs are made and decorated.
- In watch shops .
- In the industry . With the help of a metal engraver, miniature units are made that cannot be created with conventional tools. They also process hard-to-reach places in detail.
For the needs of consumers in the market of electrical equipment, there is a large assortment of different models of tools with a flexible shaft for domestic and professional use.

Reviews
According to numerous consumers, engravers and drills initially belonged to the number of insufficiently ergonomic tools. It was possible to fix this by using a flexible shaft in them. Its presence in the device equipment is appreciated by many professional masters and amateurs. Due to the flexible shaft, the device has the following advantages:
- During the operation of the device there is no excessive load on the hands. This is due to the fact that the shaft head is several times lighter than the power tool itself.
- The accuracy of the work performed is increased.
- The master can use the nozzle in the most inaccessible places.
- During the use of materials that are difficult to process, due to the absence of vibration effects on the equipment’s service life, it does not decrease.
Which power tool to choose?
For those who decide to purchase the tool, experienced craftsmen recommend paying attention to the following nuances:
- It is advisable for beginners to buy their first engraver with a full set of nozzles. This will make it possible to immediately start work and to figure out which nozzles it will be more convenient to use. The next tool is mainly bought without a set. In this case, the existing nozzles are used.
- It is necessary to decide for what purpose the engraver will be used. Cutting, grinding and grinding is best done with a powerful power tool. In case the work is planned to be carried out at a great distance from outlets, it is recommended to use battery models. Compared to network ones, they are much heavier, in addition, they have low autonomy.
- Artwork can be done using a compact battery or network mini-engraver. Judging by the positive feedback from consumers, the Ultratech Cordless Precision model has proven itself well. This mini engraver is a unique machine. In its dimensions, it is no more than a ballpoint pen. The device has an original design and good ergonomics. According to the reviews of the owners, it is very comfortable in the hand. However, this tool is highly specialized: it is intended exclusively for artistic engraving.
User's manual
During operation, an engraver equipped with a flexible shaft, it is recommended to follow certain rules.
First of all, you need to prepare the necessary nozzles. This will allow in the future not to waste time searching for them. Nozzles must be carefully checked. It is undesirable to use worn ones, since they can damage the tool. The engraver and the drive shaft must also be inspected before starting. There should be no mechanical damage on their surface.
Before starting work, it is advisable to rub the surface of the instrument with paraffin. This will prevent chips from sticking to it.
During operation, it is important to take a break every 20 minutes. This will prevent overheating of the equipment and its failure. It is especially important to allow tools that are not equipped with forced ventilation to cool on time.
It is better to work with soft materials at slow speeds. Otherwise, a high rotation speed will entail overheating of the tool or fusion of the edges of the workpiece. At medium speed, it is recommended to work with metal. It is best to process hard natural stone at maximum speeds.
During operation, dust and small particles from the processed products are strongly accumulated on the fan blades. It is advisable to regularly clean the ventilation devices with a soft cloth dampened in soapy water. Using various solvents or other detergents for this purpose is not recommended. Otherwise, this will entail premature damage to the blades.
Finally
Engravers and flexible shafts are fairly reliable devices. The duration of their operational life depends on how meticulously the master will follow the instructions and recommendations.
