Metal Machine This machine is designed for machining in order to form a given surface by removing material or by plastic deformation. Processing is performed mainly by cutting blade or abrasive tool. Machines are also used to smooth out the surface details for obkatyvaniya surface rollers. Metalworking machines perform cutting non-metallic materials such as wood, phenolic, nylon and other plastics. Special machines are treated as ceramics, glass and other materials.

Metal-working machines are classified according to various criteria, in Depending on the type of process used cutting tools and packaging. All commercially available machines are divided into nine groups, each group includes nine types. Machines of the same type may differ layout (eg, universal milling machines, horizontal, vertical), kinematics, ie a set of links that transmit motion, structure, governance, size, accuracy of processing and other Standards identified the key dimensions that characterize each type of machine. For lathes and circular machines, it is the largest diameter of the workpiece for milling machines – length and width of the table, on which set piece or equipment for cross-planer – the greatest stroke of the slide with the tool. Group of similar machines that have a similar layout, design and kinematics, but have different basic sizes, of size range. Thus, the standard for general-purpose gear hobbing machines provided with a diameter of 12 sizes of installed products from 80 mm to 12.5 m. The design of each size machine, designed for the given processing conditions, is called a model. Each model is assigned a code number – the number that consists of several letters and numbers.
