Definitions

• the cells In order to increase the speed of the shaft, which consists of the regular recesses located on it, the cells, in the process of printing, a layer of paint is applied, the excess is removed. For this reason, the cells receive a finished volume of paint, which is then transferred to the print media or to the rotary roller.
• a high accuracy of the location of the cells on a cylindrical shaft is required, as well as a very high depth. Depth of the cell is from 10 to 50 microns. Permanent contact with a flame rod made from hardened steel results in a loss of quick release.
• the process of mechanical wear and tear is supplemented by a convenient impact of excrement, including salt discharges, organic waste and t. ⁇ . that reduces the terms of service of the shaft.
• a significant disadvantage of using steel shafts is their heavy weight.
• the long, long one meter weighs about 70kg. This creates labor costs when installing and replacing shafts, which requires special experience and tools. The likelihood of accidental disruption of disruption of health.
• the first type provides a special layer of oxide of oxide or aluminum oxide with a thickness of 200-250 ⁇ m, deposited by a plasma spraying method.
• the second type is a layer of aluminum oxide with a thickness of 25-50 ⁇ m, formed on a cylindrical shaft, by anodizing in the sulfur dioxide. In this case, the depth of the spatter cells due to the laser beam should not increase the thickness of the anodized oxide.
• the main disadvantage of the method of laser processing is the use of very good equipment for automatic laser control.
• grooves provided by the laser beam do not always have the correct shape. Varying the wall and the bottom of the cell results in a loss of storage space and an unnecessary loss of life.
• One-sided oxides are mostly found in amorphous aluminum oxide, which is low and low in weight. Sales are largely hydrated (water content in them rises 10%), and also contains about 20-20% of the electrical energy, which is insignificant. When the shaft is heated, the electric components and water are removed from the process of operation during operation, which results in a reduction in the risk of harm to the device and to the risk of harm to it.
• the proposed shaft is manufactured from a basic high-quality aluminum cylinder made of an alloyable alloy.
• For the working (external) cylindrical movement of the unit it is convenient to switch to a separate accessory, a separate compartment and a volume of depressions.
• the oxide layer has a high degree of adhesion to the aluminum base and is applied in the same way as it was in the correct, correcting the conversion of the area.
• Oxidation is carried out in an ecologically safe, weakly alkaline aqueous electrolyte, at a temperature of 15-55 ° ⁇ .
• Pulse voltage is supplied from 50 to 1000 nectomb (amplitude values). The pulse repetition rate of 50-3000 Hz. Density of current from 2 to 100 ⁇ / dm 2 . Due to the fact that the shaft is made of aluminum alloys due to the impact of plasma reactions, there is a slight incidence of 700, only 50
• Oxidized metalworking which is manufactured on the basis of aluminum parts, is mainly made of aluminum, which is a matter of difference between aluminum and aluminum.
• the quick-moving structure of the oxide depressions is the ideal matrix for the creation of the favorable depressions by filling in this property with the fully-equipped property.
• various (depending on the required functional properties) metals and organic compounds are used in the present invention.
• Such materials which are absorbed in bulk and capillaries and in the form of an overcoat film with a thickness of 1-5 ⁇ m, protect the non-corrosive, they are not subject to Well-fed 7 Oxidized-ceramic waste intensively absorbs the paint, which takes into account the washing of the shaft when changing the system in the system.
• the current turnaround of the space which consists of the higher interconnections (shields) between the cells, allows for a complete grinding of the angle to the wide angle.
• the grinding depth is 2-10 ⁇ m. The whole operation is to ensure the maximum symmetry of the external rotor, the positive central shaft and the automatic operation of the printing system.

Larger shafts longer than 1000 mm are also made with external (fig. 3), consisting of high-speed, long sleeve 5 of an aluminum alloy, which is pressed on a large-metal shaft.
• An essential advantage of this invention is that it is generally available for aluminum alloys with a low specific pressure, high efficiency, and high flow rate. With this, a high speed of the roller is ensured. The best results are obtained from the fact that the output and productivity of the process are achieved when the output is high (an average of 3,000 cells per minute).
