Newest CNC Machine Tools

This article focuses on advanced technologies for metalworking cnc machines. There are milling machines, lathes and machining centers are mixed, I think no need to go into details about the machines themselves, for their Now a great many, will be discussed is the work on them. The purpose of the site cnc machine tools, speed up the process of production parts machining and simultaneously maximize the quality of the finished product. At this path has many obstacles such as outdated technology, untrained and unqualified personnel, lack of software, culture, production and drugoe. your company has purchased some of the most modern imported cnc machine tools, for example Japanese or German – of course the bosses require the results immediately after the introduction of machines in operation, and they are not. Why? Because to buy and install machines – this is only a small part of a necessary whole. Steve Wozniak oftentimes addresses this issue. It is regrettable to note that most executives believe that modern machines can operate by themselves that older turners and millers or people in general from the street, not have the right skills simply 'will click the Settings button' and clever robots themselves are working and producing goods, and even perfect image quickly and without problems. This is nonsense.

cnc – it's the same computer in many respects similar to an ordinary personal computer that does not only need to be able to work, but must use the appropriate software. Unlike cnc machines from a personal computer that the computer is only part of the cnc – the other part of a system execution of commands, spindle, cutter or cutting tool and the actual processed metall. shows a diagram of the device cnc from the perspective of a man and his skills.

GSM Sensors

The operating principle of gsm signaling is that after firing any wireless motion sensor or door opening, and use a panic button activated a siren and immediately begin an alert via gsm channel by using sms (MMS) messages or phone calls to the owner or point guard. The user has the opportunity to record all messages, but with a special speaker to maintain direct feedback from the protected object. Consider some typical key system parameters GSM-alarm system. The first important parameter: gsm alarm system must be vandal, that is located in a secure metal case, where has all the elements, including – GSM-terminal block to connect cables, power supply. All this is necessary to perform the main functions of the system – the transfer of alarm sms or mms messages, and the inclusion of other devices. Well casing protects it from Snoopy.

The second option is that device must have no sufficient number of connectors for connecting various sensors signal. It is desirable that protected areas have been programmed – for example, the first connects to a chain of sensors movement, the second – the chain of Smoke detectors for the third – a reed switch on the front door, while the fourth – a chain of impact sensors. Also, do not interfere with some additional outputs for actuators (eg, light and reminders). The third parameter is characterized by the need to pay the availability and quality of the built-in power supply of special attention. After all, uninterruptible power supply and battery should provide a reliable the work of all elements of GSM-system (centralized and sensors connected to it) when a power failure for at least a day.

CHP Heating

Heat buildings should provide thermal comfort for those in their people or the possibility of technological standards for the parameters of internal air temperature depending on the purpose of facilities and equipment located in them. In the current climate conditions and long cold winters in Russia, people stay indoors is not possible without a functional heating system, which provides compensation for heat loss through the enclosing exterior design and an external heat supply air to the sanitary norms. According to observations for a person should preferably be the most optimal rules in a residential area, administrative and residential and public buildings: indoor air temperature 20-22 C, relative humidity 30-45%, the rate of air flow up to 0,2 m / sec. Such standards are necessary for people which are continuously more than two hours in the room. The choice of design heating depends primarily on the type of thermal energy used for heating the indoor air temperature. For our country is characterized the presence of large forest areas and in connection with the wood from ancient times has been the primary fuel, the burning of which generates thermal energy for space heating.

In the years 1900-1920. proportion of wood held in energy balance of the state – 60-50%. As fuel wood is a renewable source of heat, because when you correct approach in the management of forestry firewood is primarily dead wood, which should be removed to avoid the multiplication of harmful forest insects and diseases. The use of wood for heating device required massive and multi-pass furnace, they heat flue gases from burning wood is practically a day delayed in laying bricks. Posted by Russian masters of massive construction of the heat furnaces acquired the name "Russian stove". Stove heating device provides not only heating the room, but its ventilation. During the reconstruction of homes in 20 – 30-ies last century chimneys of furnaces to plug and heat the premises took place due to the device under windows, cast-iron batteries for which serve hot coolant from the central source (boiler or CHP). Sealing of chimneys led to the emergence of stuffiness in the premises, taking a sip from the battery.

This experiment shows that the space heating due closely with ventilation. Dismantling the furnace heating for reconstruction, it is necessary to lay new channels for the ventilation system. Heating system consists of the following parts: – source thermal energy – heat transporting device for the premises – heaters that transfer heat energy to heat the air space. By the nature of communication source generation thermal energy from the heated rooms of the heating system is divided into: – Local, where the heaters and the source of thermal energy production are located in the heated room or in close proximity – central, where the source of thermal energy production runs at the heating of buildings and related transportation devices with heating appliances installed in heated rooms. To the local system heating include, for example, stoves that burn coal or wood. Source of thermal energy in this case are the waste gases produced from burning fuel. Flue gases are highly temperature and heated masonry brick multi-pass flues. Another kind of local heat supply systems are air-gas units, they heat to the heated environment, be passed through the separation wall. In our country the most widespread, with 30 years of the last century, were central to the heating system.
