electric planers used for leveling the surface of a wood board or board along the fibers. The planing of the surface is carried out by rotating cutters, which are driven by an electric motor. The lowering and rising front ski changes the depth of penetration of the cutting cutter into the solid wood. If you remove the protective cover and fix the planer on the workbench, you get a machine that is often used in woodworking.

The IE-5707A electric planer helps to quickly process a large area surface. The planer can be used to process a wood surface with a width of 100 mm and a depth of 3 mm. Its cutting elements are rotating cutters driven by an electric motor. You can vary the depth of processing. The electric planer can work from a household network. Before working with an electric planer, be sure to fix the board on a workbench. Move the planer only in the direction of fiber growth and make sure that chips and sawdust do not fall under the skis. After two or three passes, a break is taken, firstly, to check the degree of processing of the part, and secondly, to avoid overheating of the tool's electric motor. Planer knives become dull after 2-3 hours of work, and the quality of planing becomes much worse. During a break in work, put the planer on its side or with the skis up. Chips and sawdust can get under the ski planer guides, then the depth of cut of the wood layer can change, so you need to monitor this.

The reasons for uneven surface treatment of wood may be an incorrect and uneven arrangement of cutters and blunting of their cutting part. It is also possible to clog the sliding surface with a large amount of sawdust or chips.

Overheating of the electric planer motor and its failure can occur due to pressing the tool from above during operation and from the lack of lubrication in the seals.

The surface processed by an electric planer is not always smooth and smooth. The first defect occurs when the cutting cutters are located incorrectly and unevenly in the groove relative to the level of the skis. The second defect is the result of using blunt cutters.

Safety measures when working with an electric planer consist mainly of good wiring, careful handling of the cutting tool and turning off the tool during a break.

After working with an electric planer, it is necessary to remove the cutters from the grooves, clean them with kerosene and put the tool in a box.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Black hole in a test tube 09.08.2017

Employees of Stanford University managed to create a small artificial black hole in the LCLS laboratory - for this, American scientists used a super-powerful X-ray laser facility.

"We focused the laser beam on a point hundreds of nanometers in size, and then began to observe what happens to the iodine and xenon atoms that were present there. They lost all their electrons in an amazing way," the researchers say.

Subsequent experiments showed that iodine particles irradiated by a super-powerful laser begin to behave like black holes - they "steal" electrons from neighboring atoms, accelerate them, and then "spit them out." The molecules, as a result, annihilate.

"All this is very reminiscent of the behavior of supermassive black holes. In general, such experiments help to better understand the basic principles of the organization of matter in the Universe. As it turned out, these principles, if not the same for all levels of existence, are very similar," they conclude physics.
