Iron bending the material used HT200-HT300, in accordance with GB6092-85 standard manufacture. Iron bending of the face using the scraping process, after two manual annealing, is bending accuracy and stability, wear resistance changed for the better. Bending use and precautions iron bending for inspection, checking vertical mounting machine machinery can check on the plate workpiece verticality phrasebook fitter crossed. Iron bending not in humid, corrosive, high or low temperature environments and storage, the use of cast iron plate bending when the first installation and commissioning, and then wipe clean the face plate bending, no problem in identifying the case, re-use. Bending uses: bending into iron bending, bending angle, T-slot plate bending, general curved panels, splice plate bending, bending granite, marble curved plate, granite curved plate, right angle by iron, Right Angle by the board, foot rectangular plate bending, bending test. Bending Uses: detection and machining parts in the fixture. To inspect the part of a 90 ° angle, maintenance, inspection equipment related components perpendicular to the surface of degree, also commonly used in bench marking. And commonly used in the testing, installation, check the vertical face of machine tools, and can be checked on the cast iron plate workpiece verticality, for high-precision machine tools machinery and equipment inspection and is not perpendicular to the degree examination.
