When drilling, threading, assembly work, it often becomes necessary to clean blind holes from metal chips. For this purpose, various magnetic pencils, suction and other devices are used; we have already discussed some of them in this section of the magazine.

Another chip removal device was developed by the participants of the NTTM of the Kolomna Diesel Locomotive Plant. Its feature is the safety of the robot when blowing metal particles from blind holes and closed planes of parts. This is facilitated by the constructive solution of the instrument.

It consists of a quick-change end switch, which serves to connect to the pneumatic network, cylindrical bushings, a special cone divider and a nozzle. The built-in spool acts as a bypass valve, creates the necessary mode of air flow when working with a tool.

The main part of the device - the divider - serves to create the main and protective air jets.

The first through the central hole and the nozzle is directed into the part and blows the chips. A protective air screen is created by the conical surface of the divider - it protects the worker from flying chips and drops of cutting fluid or oil.

Vacuum gun
Chip remover: 1 - tubular nozzle, 2 - cone splitter, 3, 4, 6 - cylindrical bushings, 5 - spool, 7 - fastening unit, 8 - quick-change end switch

Vacuum gun
Gun-vacuum cleaner: 1 - fitting to the pneumatic network, 2 - body, 3 - barrel, 4 - air supply tube

A similar safe device was created by the innovator V. Ilyushin at the Kuibyshev Machine Tool Production Association. This is a pistol connected through a fitting to a compressed air network. A short "barrel" Ø 25-35 mm has another one - a tube Ø 8 mm coming out from the inside, through which compressed air enters the hole to be cleaned. Capturing metal particles, he brings them out.

Both devices greatly increase labor productivity and hole cleaning efficiency and improve working conditions.

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. ... >>

Mega BEAST Electric School Bus 07.11.2023

GreenPower Motor Company has introduced the new Mega BEAST electric school bus to the US market, featuring the largest battery pack and record-breaking range. The model is designed for use in rural school districts where long distances require long travel times, as well as for efficient use on busy routes.

Mega BEAST is an improved version of the Type D electric school bus, known as BEAST (battery electric automotive school transportation). The initial model, introduced in 2019, is being successfully piloted in various school districts.

The new product, also classified as Type D, features a larger LFP battery (with a capacity of 387 kWh), which increases the range to an impressive 483 km, more than doubling compared to the previous model. LFP batteries, with added safety features and high energy density, also offer a long service life despite a higher initial cost.

The company emphasizes that the Mega BEAST offers "the longest range and largest battery in a school bus." This is especially important for rural school districts that require significant distances between remote communities. The bus is also suitable for long-distance school trips and extra-curricular activities, and the high energy reserve is useful on busy routes where there is no opportunity for quick recharging during the day.

The Mega BEAST electric school bus is scheduled to be produced at GreenPower's California and South Charleston, West Virginia plants beginning in 2024.
