Today to present the production of metal-free is impossible. Therefore, the very popular metal lathes. Leading position among these are the cnc milling machines. The direction of motion spindle can be divided into two groups: vertical milling, and horizontal milling. Vertical milling machines are mainly used for drilling, boring and reaming holes, the formation of grooves and etc. This is facilitated by two types of spindle movement: rotational movement and feeding.
The advantage of these machines is the possibility of quick change tools at the correct diameter holes and the size of bore surfaces. Still worth paying attention to the point that the machines can handle parts with virtually all types of material. Just keep in mind that the processing of cast iron and other brittle metals heated cutting edge instrument is not significant, and in case of processing other materials require the mandatory use of coolant. The design of spindle assembly of these machines makes it possible to carry out processing at high speed and reach excellent precision products. On milling machines usually use two cnc systems – cyclic program control unit (CPU) and simply control (CNC). Machines with more CPUs are easy to use, because the program performs only the cyclic work machine, and the other geometric configuration has been done with working parts (lugs, sockets, etc.).
cnc machines also operate from a fully sampled data set forth in the program. y – you may have come to the same conclusion. Before how to choose what kind of machine to buy and what system cnc supply him should take into account several factors: what type of production it will be used (standard, small-scale, mass), the accuracy of existing products; size, complexity of installation and adjustment of the machine. To create a fail-safe machine operation, observe the following conditions: guard rotating and moving of the machine in protection against relegation coolant, chips. Bear in mind needs ventilation and lighting provide grounding machine leaders in producing and selling cnc milling machines in the former Soviet space are Ryazan Machine Tool Plant, Bogorodsky Instrument Co., of Petersburg company Yusto "etc. Not bad equipment imported from Germany and Bulgaria.
