In the conditions of the automated production of metal-cutting tools are especially high requirements of reliability and durability, especially when cutting hard materials and alloys.
On lathes one of the most common operations — machining centers. And here a lot of time is usually lost on such auxiliary stage, both the clamp and release the part in the Chuck. Especially noticeable these losses in large-scale and mass production. Participants NTTM-78 with the Moscow machine-tool plant named after Sergo Ordzhonikidze has developed a cartridge that at the beginning of the rotation he grips the workpiece. In what way?
Old hunters, when there was a fraction that came out of the difficulty is quite simple: crumbled in the pan scraps of lead, covered them with heavy disk and rotated it: rolling between two surfaces of the lead pieces took on a spherical shape. The same principle is incorporated in the machine used in the ball bearing industry for the finishing of the balls. They also run between the two discs, getting the perfect spherical surface.
After a protracted and rather overhaul purchased the manor house, it was found that to check have not only a “bare walls”, but with almost empty pockets. I think that in such a situation may be some readers of the respected journal, so I want to share with them my experience (From my life experience I know in Russia do not earn so much, how many you can save) So I had to switch to the manufacture of furniture And started with a headset for the hallway, or rather, with the individual items that formed subsequently to complete the set.
Combination wrench for cylinders. Probably no industrial sector or agricultural workshop now can not do without gas welding or cutting metal. Widely used and effective method such as welding in protective atmosphere of carbon dioxide. In all these cases, the workplace gas delivered in cylinders; and to connect them to the system burners, gas welder Read more…
Young metallurgists, participants of the exhibition NTTM-78, developed a key for their production needs: screwing graphite electrodes Ø 300 mm electric steel furnaces. However, they believe that the principle laid down in its design, applicable and to create a tool with the other, but a close target (for example, for unscrewing the studs).
Once in the journal “modelist-Konstruktor” I read the article “the Farmer’s sloping field.” The air route is very much needed in the highlands. But in nature, there are many horizontal areas, overgrown shrubbery, marshy ravines, through which transportation of cargo is also very difficult. In addition, many farms have often to move cargo over short distances — for example, on farms. For this I suggest using a rope conveyor. It is much easier air road, offers the opportunity to assemble the system on their own, for example, in the workshops of the kolkhoz or sovkhoz.
When carrying out installation work related to installation of structures on mortgages supporting parts of foundations, as a result of violation of technological process or as a result of its imperfections may be difficulties caused by irregularities in the supporting surfaces (local distortions, holes, etc exceeding permissible limits). Such situations often arise in the installation of industrial equipment, but such cases are not uncommon in everyday life. For example, the use of embedded items in the Foundation in the construction of different buildings on a country or a plot.
Yes, this oven lay on the wood, and… motors that require repair. “Burn” them in her invited young innovators Omsk CHPP-4, participants NTTM-78. It is easy to imagine how much work and time consuming in the repair of electric motors, the extract from the grooves of the rotor and stator are tightly Packed windings with insulating filling. In furnace insulation under high temperature burns, its volume is reduced by more than a third, and the wire is easily removed.
In between use this massager easily turn into a child’s toy — so he is similar to a traditional wheeled design for kids. However, this is a serious tool adults, whose main task is to serve the health. Because with the help of this device very efficiently carried out, the respective kneading areas of the body, which the doctor prescribed dynamic massage.
