For nc vertical lathe rough selection of the release date: 2019 - 12 - 26 author: click: usually car milling compound CNC lathe processing was carried out on the blank, for the installation of CNC vertical lathe parts material and the corresponding mechanical properties to choose. Car milling compound CNC lathe parts of his performance is very good material determines the type of the blank, as used in the cast iron parts tend to have the forging blank, and his external steel parts is simple mechanical performance, of course, also is not very high, so we will use bar, if it is some of the more important steel parts, because want to have a good performance, so good to use forgings. Parts of the structure and the external size are relatively simple, nc vertical lathe with free forging blank many time, if complex that we will use the forging. Want to use new technology, new material and new energy to improve the mechanical processing, of course, we also think of cold rolling, forging, extrusion and metallurgy, and other applications, so that it can be very good to reduce mechanical work, also need not on CNC vertical lathe for machining. If we produced before to determine blank, that we want to know from the premise, is like a blank in the field production ability, and so on. For selection of CNC vertical lathe blank: 1. Parts of material and mechanical function requirement parts material processing properties and mechanical function roughly determine the kinds of blank. Steel parts when shape is simple and mechanics function often use bar stock, not high demand for steel parts, in order to obtain good mechanics function, should choose forgings, when the shape function of complex mechanical requirements is not high in steel; Commonly used material or forging blank non-ferrous metal parts. 2. Parts of the structure and shape appearance, size large and the structure is relatively simple parts blank multi-purpose sand mould forging or cold forging; The blank multi-purpose complex forging; Small parts available die forgings or pressure forging blank; Multi-purpose forging blank plate steel parts; The blank shaft parts, if steps were small diameter, available bar; If the step size is large, the appropriate choice of forgings. 3. Production platform, the size of a large number of a large number of production, accuracy should be adopted and yield rate are higher blank manufacturing methods. Modelling of casting by metal mould machine and precision forging, forging die forging or precision casting. In a piece of small batch production be wooden craft or free forging to manufacture blank shape. 4. Existing production premises to determine blank, necessary combined with the produce of the premise in detail, such as the actual field blank manufacturing level and ability, the possibility of outsourcing, etc. , otherwise it is not reality.
