Crossed platform (flat) when using the first installation and commissioning. Before you can use. On the cast iron plate no qualified installation is meaningless work, installation and commissioning of a non-professional cast iron plate is illegal to operate, it is possible to damage the structure of cast iron plate, and even cause the cast iron plate deformation, so that it is corrupt and unusable . Therefore, before use, we have a professional staff of the cast iron plate installation, installation of non-professionals is illegal to operate, should absolutely not be used. Crossed platform (flat) After installation, wipe clean and iron face plate, used in the case confirmed that no problem using the process, to avoid artifacts and cast iron face plate has a radical impact, prevent damage Cast iron face plate; workpiece weight but can not exceed the rated load iron plate, which will cause lower quality of work, there may be damage to the structure of cast iron plate, and even cause the cast iron plate deformation, so that it is corrupt and unusable. Crossed platform (flat) for a variety of inspection, such as the dimensional accuracy of the reference plane with precision measurement and inspection of measuring a variety of machine tools, inspection of parts, line deviation and make precision crossed, cast iron plate is machine tools, machinery manufacturing, electronics manufacturing and other 20 kinds of industries indispensable product. Cast iron plate is crossed, measuring, welding, tooling process is absolutely essential table, cast iron plate can also do mechanical test bed, and so on. Cast iron plate crossed standard and precision parameters: iron dash panel / iron platform according to GB / 4986-85 standards for manufacturing, products made of plate and box-style ribs, face a rectangular, material HT200, face scraping inquiry process work surface can be processed V-type, T-type, U-shaped groove and holes, long holes and so on. Cast iron plate is flat reference instrument for part inspection or crossed. Tablet installation should be raised to the level of the load are distributed in the pivot, the ambient temperature should be used to prevent vibration crossed flat iron / cast iron crossed platform standard and the corresponding level of standards: Cylindrical tolerance causes: 1) the rotational axis of the workpiece cast iron table with pump power imbalance direction 2) of the headstock and tailstock axis does not coincide 3) axially elastic deformation process is not the same system 4) poor rigidity of the workpiece, the elastic deformation is too large 5) an elongated grinding shaft, thimble top tight bend leaving the workpiece 6) center frame improperly adjusted 7) cast iron table rail lubrication pressure, generated in the campaign swing 8) leaving the grinding amount is too large workpiece bending 9) Coolant not adequate measures to prevent a) re-centering cast iron table or machine table 2) pad pad of paper or a thin copper in the ground and other tailstock
